Engine coolant has three jobs. The first is to protect the aluminum engine parts; the second is to keep the engine from over heating and the third is to keep the engine from freezing. When a shop checks your coolant they put a test strip in it to check the acidity of it. As the coolant deteriorates it becomes acidic and starts to eat away at the aluminum engine parts. The shops also have another tool to check the temperature of the coolant. When it is new it should go down to approximately minus 50 degrees celcius. A shop will usually suggest doing a coolant flush when the coolant doesnât go below 30 degrees Celsius.
