COOLIN' OUT

摘要

When you're idling at the light, or stuck in a traffic jam of cars waiting to exit a car show, the one thing you have to do is keep it cool. Now, we're not talking about your temper or your patience, we're talking about the cooling system in your car, and in specific the water pump.
