Noisy brakes can be caused by any number of reasons, such as:

  • Thin brake linings
  • Wear indicators
  • Cracked linings
  • Defective pads
  • Poor quality parts
  • Normal occasional brake squeal

A Check Engine Light can be caused by many factors, such as:

  • Loose gas cap
  • Emission control device failure
  • Mechanical problem with the engine
  • Up to 100 direct or indirect causes
  • Normal occasional brake squeal

If you’ve had your vehicle repaired for a Check Engine Light and it comes back on soon after the repair, it may or may not be related to the repair. Remember that the Check Engine Light indicates a failure of up to 100 different causes.

Because a Check Engine Light has so many causes, it is extremely important to have it repaired. Only by having your vehicle repaired each time the Check Engine Light comes on, can you safely operate your vehicle and be assured that you are not causing additional damage and expense to your automotive repair budget.

Note: DEQ will not test your vehicle if your Check Engine Light is on.

Common causes of poor performance are:

  • Vehicle overdue for tune-up
  • Fuel injections system is dirty or malfunctioning
  • Computer or sensor malfunctions
  • Poor quality of fuel

Answering these questions will help a technician diagnose the source of engine malfunctions:

  • When was your last tune up?
  • Is you check engine light on?
  • What brand and quality of fuel are you using?
  • Does your car hesitate or ping? At what speed?
  • Is it worse when warm or cold?

Any of these factors may cause your car to pull to one side:

  • Alignment is off
  • Brake calipers are sticking
  • Radial tire pulls
  • Worn suspension bushings
  • Worn suspension parts

Answering these questions will help a technician diagnose the source of steering pull:

  • Does it pull at all times, or only when braking?
  • Does it pull only while accelerating?
  • Were any repairs recently performed on the vehicle?
For the vast majority of drivers, oil should be changed every 3 months or 3,000 miles. So why do many owner’s manuals recommend oil changes every 5,000 to 10,000 miles?

This recommendation is based on what the manufacturer calls normal driving conditions. Unfortunately, the term normal is very misleading. The vehicle manufacturers definition of normal is a vehicle that is driven long distances, and more than 30,000 miles per year (Most of us drive 10,000 to 15,000). Most people drive their vehicle under severe conditions. If you drive in extreme cold, dusty conditions, or stop and go traffic (most of us) then you are driving in severe conditions and should change your oil every 3 months or 3,000 miles.

Our goal is to not only prevent costly breakdowns, but also reduce your overall cost per mile vehicle expenses. Regular oil changes are the cheapest way to protect your automotive investment.

The number one cause of preventable breakdowns is not performing the regular scheduled maintenance for your vehicle. The following services should be performed on a regular basis:

  • Vehicle inspection
  • Change transmission fluid
  • Periodically change belts, hoses and thermostat
  • Flush the cooling system
  • Inspect brakes and flush brake fluid
  • Replace air and fuel filters
  • Replace timing belt and water pump

Our staff can provide you with the manufacturers maintenance recommendations for your vehicle and suggest services based on those recommendations and your specific driving habits.
