Limited-time Offer on New Brake Pads

replacement brake pads LongmontEach manufacturer of replacement brake pads offers a wide selection so choosing which to go with can be confusing. In a 2014 review of replacement brake pads by Consumer Reports, upgraded or severe-duty pads were only recommended “if you tow, carry heavy loads or numerous passengers often, live in hilly or mountainous areas, or have a daily commute down a steep grade”. While price and performance or important considerations, choosing certified replacement brake pads, like NAPA’s line offered at Best Auto Repair in Longmont, is the most important factor.

Types of Brake Pads

Semimetallic: Pros of this type of pad are their durability and heat transfer; cons are that they tend to wear down rotors more quickly and may not do as well at lower temperatures, and can also be noisy. Semimetallic brake pads are mad up of inorganic fillers, friction modifiers and 30-65% metal, which could be graphite, copper, iron powder or chopped steel wool

Low-metallic NAO: These pads only contain 10-30% metal (usually copper or steel) mixed with organic matter. The metal component increases brake performance and heat transfer, but creates more dust and noise as well.

Nonasbestos Organic: Also known as just organic or NAO, this type contains glass, rubber or carbon fibers mixed with high-temp resins and other filler components. Being softer, they are quieter but also wear faster and create more dust.

Ceramic: The most expensive kind of brake pad because they are cleaner, quieter, don’t accelerate rotor wear and offer optimal braking performance. As you probably guessed, ceramic pads are made of ceramic fibers, bonding agents, nonferrous filler and maybe a bit of metal.

According to Consumer Reports, it’s most important to look for certified replacement pads; the most expensive or upgraded options may not be the best choice for your vehicle and driving habits. The Dual Dynamometer Differential Effectiveness Analysis, or D3EA, is voluntary, conducted by an independent laboratory and the hardest certification to receive. NAPA was among only three other companies to pass the stringent D3EA test when it was first introduced in 1996!

From now through June, Best Auto Repair is offering $50 off qualifying NAPA brake products– so if your brakes are squealing, make an appointment today to take advantage of this great deal!

Special on AC Recharge or Service

recharge car ac LongmontDid you know that the refrigerant used in your car’s air conditioner can damage the environment? That is why the EPA requires technicians to be certified and use approved recycling equipment when working on a motor vehicle’s air conditioner. Interestingly, the “EPA does not require leak repair before refrigerant is charged into a vehicle” but anytime a car’s AC system is opened for repair or just maintenance, the refrigerant should be recycled (which means cleaned of impurities). Best Auto Repair in Longmont has certified technicians and EPA-approved equipment to recharge your vehicle’s air conditioner, and can also handle all necessary repairs should any leaks be detected.

3 Options to Recharge Your Car’s AC

  1. Adding more refrigerant– Although topping off the system will result in a noticeable temperature improvement inside the car, it could also actually impair the air conditioner’s performance. Mechanics cannot precisely measure how much refrigerant your vehicle currently has when brought in, and guessing how much to add can result in either undercharging or overcharging it.
  2. Draining and refilling– An evacuation and recharge service removes any guesswork because the technician is able to refill the system to the exact manufacturer recommendation. All of the existing refrigerant is drained and impurities are removed through a cleaning process before being introduced back into the AC along with any needed new amount.
  3. Repair leaking components– Although an electronic leak detector is usually successful in locating the problem, small leaks are sometimes difficult to pinpoint. However, although topping off or recharging a system are effective approaches, they provide short-term benefits and only repairing a leak will improve your vehicle’s AC for the long-term.

Now through the end of June, Best Auto Repair of Longmont is running a special for $15 off a recover and recharge service for your car’s air conditioning system! And should your vehicle’s AC system still use the outdated and increasingly expensive CFC-12, or chlorofluorocarbon, refrigerant, our shop can retrofit it to use the newer HFC-134a, or hydrofluorocarbon, refrigerant as well. Call us today before the hot weather hits!

Squealing Signals Brake Check and Repair

brake repair LongmontThe most common clue that alerts drivers to a problem with their brakes is hearing a high-pitched screech when stopping. If you hear this sound frequently (and not just after your car has been sitting in wet conditions), then an appointment with a mechanic is in order. Best Auto Repair in Longmont can make any necessary brake repair in a short amount of time and at a competitive rate.

Signs that Your Car Needs Brake Repair

  • Pulls to left or right when braking. If this happens, the brake linings may be unevenly worn or the brake fluid might need replaced if a contaminant has gotten in.
  • Less resistance when pressing on pedal. Reduced responsiveness is usually a symptom of a fluid leak or air leak in the hose. Another sign of a brake fluid leak is a puddle accumulating under your parked vehicle.
  • Grinding sound when braking. This jarring noise is caused when the disc and caliper rub together because the pads have worn away. The rotors may then need to be evened out or replaced if they have become too deeply scratched.
  • Vibrating feedback when stopping. If the pedal shakes when depressed, most likely your car’s rotors are warped. The rotors surface becomes uneven from extended periods of intense braking, like when towing or on a steep downhill. This sensation is just like what happens with anti-lock brakes on a sudden stop.

 

In addition to the above warning signs, you can also visually inspect your brake pads through the wheel’s spokes to make sure there is at least ¼ inch remaining. Most drivers assume that their vehicle’s brakes are in good working order unless they hear or feel something amiss but regular brake maintenance should not be overlooked. Best Auto Repair of Longmont can help prevent expensive future bills and ensure that your car is in safe-working order by conducting a thorough inspection and doing any needed brake repair.

Save on a New Air Filter & Enjoy Better Performance

air filter LongmontDid you know that your vehicle’s engine uses up to 10,000 gallons of air for every gallon of gas consumed? Having a clean air filter is vital for your car’s ability to function optimally: it improves gas mileage, acceleration, and overall performance while also reducing emissions and prolonging engine life. Best Auto Repair in Longmont is offering a deal now through the end of April when you install a NAPA air filter with an oil change, you’ll get $15 instant savings!

5 Reasons to Change Your Car’s Air Filter

  1. Extends Engine Life– The function of the air filter is to prevent dirt and other particles from entering the system. The internal components, such as the pistons and cylinders, are especially prone to damage from small pieces of debris.
  2. Better Fuel Efficiency– One study claims that regularly changing the air filter will boost your vehicle’s gas mileage by 10%. Another showed that acceleration increased 6-11% when a clogged filter was replaced.
  3. Decreased Emissions– When air flow to the engine is reduced, the emission control system may inaccurately calculate the proper air-fuel ratio which could also lead to increased engine deposits. The spark plugs could also begin to fail should they become too dirty.
  4. Valuable Prevention– Your vehicle’s owner’s manual will state the recommended schedule for changing its air filter, usually between every 12,000 to 15,000 miles. Swapping out an old filter for new is a quick fix for preventing many potential problems.
  5. Inexpensive Maintenance– Replacing the air filter is low-cost upkeep and is even more affordable now with the current air filter coupon available at Best Auto Repair through the end of the month.

Take advantage of extra savings on a new air filter this month at Best Auto Repair in Longmont and enjoy your car’s increased performance!

A Spring Tune Up will Save You Money & Keep You Safe on the Road

tune up LongmontWe all want our vehicles to be safe and reliable, and the best way to ensure that dependability is with regular maintenance. Keeping your car in good shape with regular tune-ups following the manufacturer’s recommendations will also keep its resale value high. Best Auto Repair in Longmont offers a thorough and affordable tune up for your car or truck that will ensure it is running optimally this spring!

Rich White, executive director of the Car Care Council, points out that there are economic, safety and environmental benefits to performing regular vehicle maintenance and stated that “Neglected vehicles do cause accidents, or a breakdown on a highway, which in itself can be dangerous.”

Basic Spring Checklist to Tune Up Your Car

  • Check the air filter– a dirty filter will not keep as much dust and dirt out of the fuel system, which results in poorer gas mileage.
  • Measure the tire pressure– under-inflated tires wear out faster and use more gas.
  • Assess the lights– make sure the front, rear and brake lights are not burned out or defective.
  • Check the level of fluids– low transmission or brake fluids can decrease performance but also cause bigger problems with other engine components.

 

According to the National Car Care Council, “Neglected vehicle maintenance leads to more than 2,600 of the approximately 43,000 deaths each year…and nearly 100,000 disabling injuries.” There are 3 major reasons why preventative maintenance is worthwhile: first, your car will run more efficiently, second, it is better for the environment, and most importantly, it ensures that it is safe to drive! Regular vehicle maintenance definitely saves money in the long run, but with the top quality tune up provided by Best Auto Repair in Longmont, it is also affordable now! Call today for an appointment to get your car in tip-top shape for spring!

Role of Catalytic Converter in the Exhaust System

exhaust system LongmontThe function of a catalytic converter is to convert engine emissions into non-hazardous gases through a chemical catalyst. It is a vital part in the exhaust system to prevent pollution. A damaged catalytic converter will need to be replaced to make emissions safe, and the highly trained technicians at Best Auto Repair in Longmont have the experience to thoroughly evaluate your vehicle’s exhaust system and return it to maximum efficiency in a jiffy.

Signs a Failing Catalytic Converter Needs an Exhaust System Check

  • Exhaust Problems: A clogged converter will restrict output and a crack will cause leaks. If dark smoke is being produced from the muffler or it smells like rotten eggs/sulfur, a faulty catalytic converter is most likely to blame.

  • Rattling Noise: The inside of a catalytic converter contains a honeycomb structure that can start to break apart due to age or damage. These pieces will rattle around internally causing a noise that will be more noticeable when turning on the car and will also become progressively louder.

  • Poor Engine Performance: If you notice a decrease in your vehicle’s acceleration, power or fuel economy, a damaged catalytic converter may be to blame. Since the converter is a vital component of the exhaust system, any problems with it will reduce overall engine performance.

  • Check Engine Light Illuminated: The sensors that monitor oxygen and fuel ratios will turn the check engine light on if they detect that exhaust gases are beyond the recommended levels. This is a strong indication that the catalytic converter is becoming inefficient, but there are many other possible reasons for a check engine light alert that only a computer scan will disclose.

If you suspect your vehicle’s exhaust system needs repair or if it fails an emissions test, bring it to the ASE-certified mechanics at Best Auto Repair in Longmont for a quick diagnosis and solution.

Diesel Service and Repair in Longmont

diesel service and repair LongmontAccording to the National Motorists Association, “it’s getting harder to make an economic case or a functional case for a diesel engine over a gas engine, at least in passenger cars.” However, if you are the owner of an older diesel car or a newer diesel truck, you need to find an auto repair shop that you can trust. Best Auto Repair in Longmont has mechanics that have gone through extensive ASE-certification training for diesel service and repair.

Diesel Service and Repair vs. Gas Engine

  • Diesel engines are more complex than they used to be; their emissions systems in particular. Their urea injection needs to be supplied with a regular amount of diesel emissions fluid. It is no longer the case that diesel engines are simpler than gas.
  • More modern gas engines are now turbocharged, so the big torque appeal of diesel engines has diminished. The newly designed turbos produce impressive torque at lower RPMs and also provide more horsepower than most diesel engines can.
  • Diesel engines still have a slight advantage in lasting longer than gas engines. But it is common for most gas engines to last 200,000 miles nowadays, which was the appeal of a diesel engine back in the day when the gas counterpart could only be counted on for half as long.
  • Diesel engines are heavy duty, usually constructed from cast iron instead of gas engine’s aluminum block. Diesels have to be stalwart to withstand the high cylinder pressure of a compression-ignition engine. This is their main advantage today- they endure hard work better than gas, and so are the logical choice for trucks used to pull heavy loads.

Federal regulations have changed diesel engines from being simple and affordable to maintain to more complicated and expensive to own than current gas-powered passenger cars. They are also not much more fuel-efficient than modern gas engines. But rest assured that if you need a diesel service and repair, the ASE-certified technicians at Best Auto Repair in Longmont have the knowledge and skills to take care of your vehicle!

Cost of an Engine Rebuild vs New Car

Rebuilding an engine, whether a ring and valve job, in-house rebuild or rebuilt exchange, is a major repair job. We feel a conservative approach, where parts are replaced as needed, makes sense and costs less, although some damage cannot be diagnosed until the engine is partially taken apart. If you think your vehicle needs an engine rebuild, bring it to the ASE certified technicians at Best Auto Repair in Longmont for a thorough diagnosis and fair repair estimate.

Top 3 Reasons for an Engine Rebuild

  1. Loss of Compression- Signs that your vehicle’s engine has lost compression are misfires, lack of power and extended cranking. A compression, or leakdown, test will need to be performed to make sure these symptoms are not being caused by other problems.
  2. Excessive Oil Consumption- If the engine is losing oil but not from an external leak, it may be that the PCV valve needs replaced (an inexpensive fix) or the whole engine may need replaced. Other sources for lost oil are stuck oil control rings, worn valve guides or dried seals or too much clearance between cylinders and pistons.
  3. Immoderate Oil Clearances- The classic reason for engine knock are excessive oil clearances. Some types of engine knock can be repaired without removing the entire block from the vehicle but partial disassembly is always required.

Remember that you will need to break in a rebuilt engine for about the first 500 miles you drive with it. Don’t surpass 75% of the maximum RPM or cruise for extended periods on the highway. Be sure to check the oil frequently, since it will burn more while breaking in, and don’t use synthetic oil. If you take care to break in a rebuilt engine, it will last longer.

Deciding if it is worth it to rebuild your engine is complicated- let the experienced mechanics at Best Auto Repair in Longmont help with your decision by first completing a full vehicle inspection so you can accurately weigh the cost of repair against buying a new car.

Affordable Water Pump Repair in Longmont

The function of a car’s water pump is simple: to cycle coolant to the radiator to prevent the engine from overheating. Internal blades send coolant through the engine and into the radiator to be cooled before starting the cycle over. This basic part is essential to proper engine function. If you suspect your water pump is wearing out, have the ASE certified mechanics at Best Auto Repair in Longmont inspect and replace it before more damage is done.

4 Signs that a Water Pump Needs Repair

  1. Whining noise from engine that gets louder when accelerating. Most likely caused by a loose pulley or worn out bearings inside the water pump.
  2. Red or green puddle under your parked vehicle. When the pump’s gaskets and seals deteriorate, coolant will start to leak.
  3. Frequent high temperature readings on the engine gauge. When the water pump stops doing its job, the engine will start to overheat.
  4. Radiator producing steam. This is the last, and biggest, warning sign of a broken water pump. Don’t risk causing more extensive damage to your engine by driving your overheated vehicle- call a tow truck instead.

Fortunately, water pumps typically last a long time in newer vehicles but, just like any other engine component, they are not impervious to failing. If you notice any of the above signs that point to a damaged water pump, the experienced staff at Best Auto Repair in Longmont can quickly diagnose and, if necessary, replace any broken parts in your vehicle.

If, unforunately, your engine does need a major repair, we currently have a special running in the local Valpak for $25 off any service over $250 or $50 off any service over $500. Click here for the coupon.

Fast Engine Mount Repair in Longmont

There are many potential reasons for odd noises or movements emanating from your vehicle’s engine; one of which is a broken engine mount. Engine mounts secure the engine to the chassis and dampen the constant vibrations caused when the motor is running. Best Auto Repair in Longmont has experienced technicians to quickly diagnose the cause of unusual car sounds or shakiness, and will expertly repair the problem- be it a broken engine mount or other damaged part.

Top 3 Signs of a Broken Engine Mount

  1. Clunking Sound- Thuds or banging noises coming from your engine, particularly when going over bumps, is probably the most common sign of a damaged mount. Impact noises are also noticeable when accelerating.
  2. Significant Vibration- Since one of the main functions of the engine mount is to absorb engine vibration, if the rubber component is worn then you may notice some increased shaking in the cabin.
  3. Engine Movement- If you suspect that a mount is broken, you may want to observe how stationary the engine is when running. A properly secured motor will not move up, back nor side to side in the bay.

As you can imagine, keeping the engine stable is critical for proper function, and if a mount is damaged then other components are being stressed and could fail sooner due to the added strain. If you notice any signs of a broken engine mount in your vehicle, bring it to the ASE certified technicians at Best Auto Repair in Longmont for a quick diagnosis and fix!
