It May Be Time to Change Your Vehicles Thermostat

The thermostat within your vehicle maintains the engine's temperature and ensures it's operating with a range that's specified in your vehicle's owner's manual. Thermostats serve two main functions, to heat the engine and keep it consistently at optimum temperature. As you drive, the thermostat gets older and worn. A worn thermostat can get stuck open or closed, leading to an array of problems. It may not be easy to determine whether the thermostat is the main problem culprit when issues occur. Below we provide a brief overview of signs to look out for that indicate the thermostat needs to be replaced.  

There's cold air blowing through the heater vents.
If the thermostat is stuck open, the temperature within the engine will decrease. 

The engine is overheating.
If the engine is smoking and overheating, the thermostat may be stuck closed. A thermostat that is stuck in the closed position will not allow the coolant to flow adequately. In severe cases, the engine can overheat in less than 15 minutes. 

There's a noticeable difference in drivability and handling.
A faulty thermostat will not be able to maintain the appropriate temperature for a vehicle to function effectively. Your engine will struggle to power the car. These problems result in a domino effect that impacts other aspects of your vehicle, such as fuel economy. You'll find yourself spending a bit more than usual to keep your gas tank full. 

If there's a problem with the thermostat, the check engine light may not always come on. It's essential to be vigilant to any potential signs that your vehicle needs to be serviced. Consistent overheating can cause long term engine damage that'll hurt your wallet. A thermostat replacement is simple and easy to fix; long term engine damage isn't.

First time at lex Brodie’s it was excellent service and the girls at the front were really helpful.
Ronald & Sally H.
Yelp: Jack and the girls at the front took really good care of me and my mom. They are professional and probably one of the most honest mechanic shops I have been to. You can tell they really want to make their customers happy and give them the most fair price they can. Jack and the sales girl I talked to broke down all the costs before starting the work so I knew exactly what we were paying for. Great staff, patient, kind, and honest. This place treats you like family and wants you to leave happy.

Have been going to Lex Brodie's for tire and alignment work for over 40 years and they have been outstanding. Sure, I've experienced a few "quirks" with them, but that also happens with any other best other shops taking care of them in good order.

Wonderful, quick service. My low tire pressure light came on while driving to work downtown. I was able to make an appointment to drop off my car at lunch and picked it up after work. No charge for checking my tires and the employees were extremely friendly and efficient even though they were busy.
