It could be a loose gas cap-or something serious like a failing catalytic converter. Visit us in Riverside for quick code reading and diagnostics. At Protrans Automotive & Transmission Specialists, we can pull the code and diagnose the problem for you.
Factory Scheduled Maintenance
Automakers provide a service schedule for each vehicle. Our Riverside technicians follow this closely for gas and diesel vehicles, domestic or import, to ensure long-term performance.
Headlight and Bulb Replacement
If your bulbs are dim or out, it's time for a replacement. Our Riverside team installs high-quality bulbs to restore visibility and safety.
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 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 Protrans Automotive & Transmission Specialists. 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 Riverside, Canyon Crest, Moreno Valley, Orange Crest or the surrounding area, come by Protrans Automotive & Transmission Specialists 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 Protrans Automotive & Transmission Specialists 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 Riverside 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 Protrans Automotive & Transmission Specialists in Riverside our professional auto repair technicians can realign it to stop the noise and fix it before your fan belt completely breaks.

Mike and his team are The BEST in Riverside! They give a fair price and stand behind the work. I have an old pickup truck, and together we are restoring it. I feel Mike welcomes you into his family gives you rides when your car is in the shop. Has late night drop off and will stay late for you to pick up your car after work. He help's get to know your situation, what you absolutely need, and what you can put off. Mike's shop has played a considerable role in getting my Dad's old truck running.
