How To Change The Coolant In Your Car

In the service manual for my 1999 Acura Integra, it recommends replacing the engine coolant every 45,000 miles. Before getting started, the first thing you want to do is make sure your temperature control is on maximum heat. For modern cars this is often an electronic control, so you may need to run the car or at least turn the ignition on beforehand to make sure the heater core is opened up. This will ensure that you replace all of the coolant in your car. Before working on the car in any way, it’s critical that the engine and radiator have completely cooled down - you’ll often see a warning for this on the radiator cap. This video will walk through the process of replacing the fluid.
