Factory Scheduled Maintenance
Automakers provide a service schedule for each vehicle. Our Defiance technicians follow this closely for gas and diesel vehicles, domestic or import, to ensure long-term performance.

Oil Filter FAQs

How often should oil filters be changed?

Consult your owner's manual to determine the maintenance interval for your vehicle's oil filter. Some manufacturers recommend that the oil filter be replaced every time you get your oil changed while others recommend every other time.

Why is water leaking on my foot on the driver's side?

The most common cause is a blocked air conditioning drain hose. This is a simple repair at Northwest Automotive LLC. There are other possible causes of water dripping on your foot on the driver's side of the car including a broken door seal or leaking heat exchanger.

Why is my car leaking a sweet-smelling fluid?

If there is a sweet-smelling fluid leaking from your car, the most likely culprit is leaking coolant or antifreeze. A coolant leak can become a serious problem. If your vehicle gets too low on coolant or antifreeze, it will overheat and may cause engine damage.

FAQs About Automobile Squeaks, Squeals and Rattles

Why are my wheels making a chirping sound when I accelerate?

The most common reason why your car's wheels make a chirping or squealing sound, especially during acceleration is a bad wheel bearing. If you notice a grinding or grating noise coming from your wheel this can also be the sound of a wheel bearing beginning to fail. If you are in Defiance, Napoleon, Bryan, Archbold or the surrounding area, come by Northwest Automotive LLC and we can diagnose the problem quickly.

Why does my car make a noise when I turn the steering wheel?

If your car makes strange sounds or clicks when you turn the steering wheel the most common cause is a low steering fluid. Over time the steering fluid decreases and air enters the steering mechanism causing unwanted noises. Come to Northwest Automotive LLC to top off your fluid reservoir with power steering fluid. The noises should start to go away immediately. If the sound returns quickly your car could be leaking steering fluid. Our professionals in Defiance can help you diagnose and repair leaks quickly and affordably.

Why is my car making a squealing noise?

It may be a slipping fan belt. Listen for a few warning signs such as a squeaking or chirping noise. Those noises are usually caused by misalignment of the belt and the pulley. If you come by Northwest Automotive LLC in Defiance our professional auto repair technicians can realign it to stop the noise and fix it before your fan belt completely breaks.

I have a 2011 Jeep Liberty, the A/C stopped working, so I called up Tim and told him. He said can you bring it in today at 1:00pm? I said yes. So I took it in, they found that all the Freon was out of the unit. So they put more Freon in plus added some dye to find if the system may have a leak. So I paid the bill. Tim said, if you have any further problems bring it back. So the next day I started my Jeep up. The A/C stop working. So I called them back on Saturday. Can you bring it back on Monday at 2:00pm? I replied yes. Returned back to Northwest Automotive. They took my jeep in and recharged the A/C unit, and checked the system for any possible leaks. So Tim filled me in on no signs of dye so go ahead drive it and if any further problems bring it back. So how much money do I owe you? He replied nothing. The next day I drove my Jeep the A/C stop working again. So I called them back and told them. Can you drop it off so we can get to work on it Monday morning. I said yes. So I called them up Monday around noon and asked how are things going with my jeep? He replied that we believe we have found the leak. So he asked you said when it would set over night that the next day it not work? I replied yes. He asked if you don't need your Jeep back today, we will let it set overnight and check and see if it is still working in the morning. So I replied yes. I called them back the next day and asked how are things going with my jeep? Tim replied it is working fine. He asked if I would pick it up later today, l said that is fine because I will not be in town till around 3:30pm. Because I was at work. So went to pick up my Jeep. Tim said I believe the problem was from the low pressure valve. It should be alright. I replied so how much do I owe you. He said nothing, if you have any further problems bring it back. I believe he is a fair and honest person. I will respect that and I will bring him some more business. Thanks again.
