    This is the only place I will take my car to be serviced at. Not only do they do a wonderful job, but they are very ethical which is hard to find these days. Would recommend this place to anyone that is having issues with their car or looking for a place for routine maintenance. Couldn’t recommend enough!

    This place is great! They do a full review of everything on your vehicle and print out recommendations of what needs to be fixed. Not pushy like some places. Staff is super nice too!

Frequently Asked Questions About Precision Auto & Diesel

Should I keep an eye on fluids and filters?

Your car’s engine is full of sensitive and delicate moving parts that rely on fluids like oil, transmission fluid, and coolant to function well. If you don’t keep an eye on these fluid levels or periodically change the filters, these delicate parts could face irreparable damage. Your car’s brakes also require brake fluid to transfer the force to the brakes to slow or stop your vehicle. It's possible for brake fluid to lose its effectiveness or for leaks to occur. If you experience abnormal brake performance, make sure to have your car checked. Coolant or antifreeze prevents overheating and freezing of the engine's cooling system. Like brake fluid, recommended service intervals vary by manufacturer and can range from roughly a few years to a recommended check during every scheduled maintenance service. Keep an eye on your coolant level to ensure there aren't any leaks. If you ever see the engine temperature warning light turn on, there might be something wrong with your coolant or the amount of coolant remaining.

When should I have my automotive parts replaced?

Your vehicle’s brakes should be examined at least once a year to identify any wear and tear and need for repair. Brake pads and rotors typically last anywhere from 35,000 to 60,000 miles, depending on how often you stop while driving and how thin or thick the rotors and pads are initially. Your car’s battery typically lasts 4 or 5 years, depending on outdoor temperature, driving frequency, and overall use – among other influences. To maximize battery life, keep your battery clean; don't leave your car unused for an extended period, and don't forget to shut off the interior lights and headlights when your car isn't in use. Driving with bad headlights can be very dangerous. Restoring your headlights can have it looking like new and can shine up to 3 or 4 times lighter when driving. You can slow oxidation caused by heat, sunlight, pollution, and harsh chemicals by parking in a garage when possible.
