Chris was a pleasure to work with. He had the tools and ability to R&R my Crankshaft & Camshaft Position Sensors without dropping the screw so he was able to get the job done quickly. It looks like I've found myself a new mechanic to work on my car's engine when it's cool . Thanks Chris.

Rocco came to my home to check out my car since it would not start. I did not want to go through the hassle of having to tow it to a repair shop and wait around. I had a problem with my starter. With repairs like this you would think you'd have to go to a repair shop but I'm relieved I was able to have it fixed at my home from someone professional. He came and checked out my problem (which took less than an hour), provided an estimate along with how much time/labor would be involved and the next day came and made the repair. And I was able to save time without waiting around for other customers and cars ahead of mine like at a shop. I'd definitely use the service and call him again in the future :)

Awesome experience!! Chris was great!! I was extremely satisfied with his service. I would recommend him to family and friends. Besides delivering a new battery and installing it, He checked all the fluid levels, checked the tire pressure and made sure all the the malfunction lights went away. He was very professional, knowledgable and friendly.The final bill was less than I was quoted, because he gave me a $20.00 discount.I asked for his card so that I could request him if I need YourMechanic services again. Love this company!!!

All about Thermostat Replacement

A thermostat is part of the cooling system that regulates the temperature of the coolant in the engine. The thermostat is a metal valve that has a temperature sensor built in. It can either be open or closed. When the thermostat is closed, it keeps the coolant in the engine. When the engine gets to a predetermined temperature, the thermostat opens allowing coolant to circulate. The circulation of coolant prevents the engine from overheating. If the thermostat fails to open, the car will overheat. If the thermostat fails to close, the engine may never reach the optimal temperature (~220F). The thermostat opens and closes many times when the car engine is running. It is the most common component in the cooling system to fail, causing the car to overheat.
