Transmission Repair – Transmission Fluid Service

By | Gresham Auto Repair | No Comments

The advancement in lubricants allow car owners to extend transmission service intervals on many vehicles with automatic transmissions.  In recent past most vehicles with automatic transmissions had service recommendations that were based on time/mileage(2-3 years/30K miles) now with the introduction of “lifetime fluids” these recommendations are 5-10 years or the life of the vehicle (100k miles) unless however the vehicle is subject to “severe duty.”

At Orient Auto Service we are commonly asked when the appropriate time is for fluid service?  This would depend on the use of the vehicle.  Severe Duty as defined in most OEM owners manuals would be defined as:

  • Operating the vehicle in extreme temperatures, above 100° F or below 0° F.
  • Carrying heavy loads or multiple passengers on a regular basis.
  • High speed interstate driving regularly.
  • Driving in hilly or mountainous terrains
  • Constant stop and go driving

Based on these definitions the majority of vehicle owners would engaged in ‘severe duty’ driving.  The winter of 2013-14 proved to be a cold and harsh winter, adding in stop and go driving would be a perfect example of ‘severe duty’ driving.  At Orient Auto Service we typically recommend customers to cut service intervals in half to account for ‘severe duty’ driving(30k-100k to 15k-50k service intervals.)

If you have questions about when you should have your cars fluids changed stop by Orient Auto Service in Gresham Oregon.  With over 20 years serving Gresham and the greater Portland Metro we have the experience to ensure your vehicle is properly cared for.

Indirect Tire Pressure Monitoring System(TPMS) on Imports

By | Gresham Auto Repair | No Comments

Most newer vehicles today come standard with a tire pressure monitoring system(TPMS), however many vehicles use an indirect tire pressure monitoring system that do not actually have sensors inside the tires to measure air pressure but detect low tire pressure by comparing relative wheel speeds via the anti lock brake system(ABS) wheel speed sensors.   As a tire looses air pressure the diameter decreases slightly.

Most older indirect tire pressure monitoring systems are not as sensitive to change in tire pressure as the direct systems that actually monitor the air pressure inside the tire.  An indirect TPMS are a fairly affordable add on to a vehicle already equipped with ABS.  Federal law requires the TPMS to alert drivers if the air pressure inside the tires drops below 25% of the recommended pressure.  The same rules apply to both direct and indirect systems causing many car manufacturers to switch to direct TPMS to meet the federal mandate.

One of the downsides to a indirect TPMS is that the warning light may not be triggered if all the tires are under-inflated because the tires are all equally under-inflated the wheels will all be spinning at the same speed and therefor the indirect system would not notice there is a problem.

However in recent years indirect systems have been making a come back starting in 2011 with all Audi models and in 2013 the Honda Accord, Mazda CX-5 and the VW Golf all switched to an indirect system.  If you are getting warning lights or have questions about your TPMS sytems bring it by Orient Auto Service for a look.  We are located in Gresham Oregon at 1550 SE Orient Drive, Gresham, OR 97080.

Power Steering Repair

By | Gresham Auto Repair | No Comments

Power steering is responsible for helping drivers move the wheel on their car with ease. When something goes wrong with the power steering, the car’s steering wheel is almost impossible to turn and in some cases it can complete lock up to the point you cannot turn the wheel at all.

If you have noticed that it is difficult to turn the wheel when you are trying to make a right or left turn, it may be because there is a problem with your power steering. The professionals at Orient Auto Service in Gresham, Oregon can run a diagnostic check of your power steering and determine what, if any, problems are present.

Wondering what the professionals will do during a power steering diagnostic check? Here is a look at some of the things they will do should you bring your car in for potential problems with the power steering.

Check the Levels of Power Steering Fluid

The level of power steering fluid present in the vehicle could indicate whether or not a problem is present. Lower levels of power steering fluid could indicate that there is a crack in the fluid lines or a potential problem with the actual power steering pump.

Look at How the Steering Pump Belt is Positioned in the Vehicle

Many people assume that when a belt in a vehicle goes, like the steering pump belt, it just snaps and breaks, but that doesn’t always happen. Sometimes the belt may slip and slide, which will cause the steering wheel to lock up.

The position of the steering pump belt can be determined by lifting the front of the vehicle up. Someone in the car will then move the steering wheel left and right. If the belt slips or slides, the car will typically make a loud whining noise.

Do an Entire System Checkup for Problems with the Power Steering

A whole system checkup could help determine what might be the cause of your power steering problems. Everything from lower steering leakage and cracks on the pinion seals to unequal tire pressure could cause you to experience problems with your power steering.

Some of the things that will be looked at during a whole system checkup include:

  • Tire pressure
  • Steering gear placement
  • Worn bearings
  • Rack and pinion seal checked
  • Hose check

Once a problem is determined, the steps to fix the problem can be taken. People who take their car to Orient Auto Service will receive a full estimate that will outline what problems are causing your power steering issues and how much it will cost to fix those problems.

If you suspect you are having issues with your power steering, get it checked out by a professional. Call Orient Auto Service today to schedule an appointment to have your power steering inspected by a professional.

Gresham Auto Repair- Cooling System Service

By | Gresham Auto Repair | No Comments

Summer is almost here and with it comes warmer temperatures. While everyone enjoys playing out in the sun, your car might not, especially if its cooling system isn’t working.

The cooling system on your car is responsible for making sure your car’s engine doesn’t overheat. While the cooling system is extremely important all year round, it is especially important during the summer months.

The warmer temperatures make it extremely easy for your car’s engine to overheat. Once an engine overheats, it could result in hundreds – if not thousands – of dollars in repair bills.

Luckily, there are often warning signs that will indicate that your car’s cooling system is in need of repair. Knowing the warning signs could help you save money on repair bills, as you prevent your car from overheating and damaging the engine.

The following is a look at some of the most common signs that your car’s cooling system is in need of repair.

Warning Sign #1 – The Warning Light Appears

This is the easiest warning sign to notice. If a car’s cooling system starts to have problems, a warning light will often appear on the dashboard. The light, which looks like a thermometer with several wavy lines, will often appear while you are driving.

Even though your warning light will tell you when you are having problems with your cooling system, you shouldn’t rely solely upon it. Sometimes your car’s system is unable to detect cooling system problems, which means the light will not appear.

Warning Sign #2 – Temperature Gauge Readers Lower or Higher Than Normal

While driving your car, the temperature gauge should read within the normal range. Unfortunately, if there are problems with your cooling system, your gauge will appear off.

When problems occur with your cooling system, your temperature gauge will often read extremely high or extremely low.

Warning Sign #3 – Poor Gas Mileage

Cars will always get the best gas mileage when they are running properly. Problems with a cooling system could cause your car to start to get fewer miles to the gallon. This happens because the fuel is unable to be evaporated properly, which results in the car getting fewer miles to the gallon.


If you suspect you have a problem with your car’s cooling system, schedule an appointment with the professionals at Orient Auto Service located in Gresham, Oregon.

Our technicians will perform a complete system check of not only your cooling system, but your entire car. Once a complete system check is performed, we can provide you with a comprehensive look at what is wrong and how it can be fixed.
