Coolant Test

Fall usually follows summer and precedes winter which might happen again this year. In case it does now is the best time to get your car ready for cold weather. Procrasting by waiting until the first prediction of a hard freeze means you may have a long wait — get sub-par work and pay more. The checkup begins with engine coolant which for decades was tested by sucking some coolant into a turkey baster looking device with floating balls or discs inside. That’s a hydrometer and it tells how cold it can drop before your engine freezes. Freeze protection still needs to be tested but if that’s the only test the technician does — politely say thank you and take your car to a real shop. Today’s coolants are different and so is the way they’re tested. In addition to checking freeze protection it’s important to perform a PH Test. Which tells how corrosive coolant is. Many coolants age gracefully and become dangerously acidic. It doesn’t take a chemistry degree to visualize what acid would do to a cooling system. The lower the PH the more acidic and damaging your coolant is. Don’t play the numbers here. Wheen coolant PH drops out of spec flush the system and install the proper new coolant for your car.
