Belt Replacement
Fan belts (or drive belts) dry out and crack over time. If you hear squealing or see wear, visit Northwest Automotive LLC in Defiance for expert belt inspection and replacement using quality parts.

Check Engine Light Diagnostics
It could be a loose gas cap-or something serious like a failing catalytic converter. Visit us in Defiance for quick code reading and diagnostics. At Northwest Automotive LLC, we can pull the code and diagnose the problem for you.

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.

Hose Replacement
Cracked, dry hoses can leak coolant and cause overheating and prevent optimum performance. We inspect and replace worn hoses to keep your cooling system in top shape.

Oil, Lube & Filter Changes
Most vehicles need oil and filter changes every 3,000 to 7,500 miles. We provide full oil, lube, and filter service at Northwest Automotive LLC to prevent wear and overheating.

Oil Filter FAQs

How often should oil filters be changed?

Consult your owner's manual to determine the recommended maintenance interval for your vehicle's oil filter. Some manufacturers recommend replacing the oil filter every time you get an oil change, while others may recommend replacing it every other oil change.

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 typically a simple repair at Northwest Automotive LLC. Other possible causes of water leaking onto the driver's side floor include a damaged door seal or a leaking heat exchanger. Our technicians can inspect the source of the leak and determine the appropriate repair.

Why is my car leaking a sweet-smelling fluid?

If there is a sweet-smelling fluid leaking from your vehicle, coolant or antifreeze may be the source. A coolant leak can become a serious problem if left unaddressed. If your vehicle gets too low on coolant or antifreeze, the engine can overheat and potentially suffer engine damage. Have the vehicle inspected promptly to locate and repair the leak.

FAQs About Automobile Squeaks, Squeals and Rattles

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

The most common reason 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 a wheel, this can also be a sign that a wheel bearing is beginning to fail. If you're 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 clicking noises when you turn the steering wheel, one possible cause is low power steering fluid. As the fluid level drops, air can enter the power steering system and cause unwanted noises.

Come to Northwest Automotive LLC to have the power steering system inspected and the fluid level checked. If the noise returns quickly after the fluid is topped off, your vehicle may have a power steering fluid leak. Our professionals in Defiance can diagnose the source of the problem and recommend the appropriate repair.

Why is my car making a squealing noise?

A squealing or chirping noise may be caused by a slipping or misaligned belt. These noises can occur when a belt and pulley are not properly aligned or when the belt is becoming worn. If you come by Northwest Automotive LLC in Defiance, our professional auto repair technicians can inspect the belt and pulley system, determine the source of the noise, and make the necessary repairs before the belt fails completely.

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.
