Boulder Auto Repair

Warm weather or cold, Boulder drivers still need to think about their family car’s air conditioning. Most Boulder people don’t service their air conditioning until after it fails. At John’s Auto Care, we can advise you on your vehicle manufacturer’s preventive maintenance schedules for air conditioning service, just as we do for transmission service, oil changes and so on.

Boulder drivers rely on their car’s coolant system to keep their engine cool. Coolant (also called antifreeze) mixed with water flows through your family car engine and absorbs heat. The mixture then flows out to the radiator where it’s cooled by air flowing over the radiator. From there the coolant/water mix circulates back through the engine to absorb more heat. There’s a reason we mix coolant and water. Water alone actually does a good job transferring heat from the engine. The problem is that water boils at a temperature that’s easily reached inside your family car’s engine, so it can turn to steam which does not conduct heat as well and is harder to contain. Also, if it’s freezing outside in Boulder, the water in your engine could freeze while your vehicle is sitting out in the cold. So, if you remember your Boulder high school chemistry, you’ll know that a mixture has both a higher boiling point and a low ... read more
