Chris Fix: How to Replace a Radiator - complete guide

Is your car overheating? Do you see coolant leaking from your vehicle?

It sounds like it's time for a thorough checkup of your cooling system. While you're at it, you'll want to use a hydrometer to check the condition and specific gravity of your coolant. A refractometer can give you an even better indication of the condition of your coolant, and it isn't a bad idea to take your overheating car to a shop for a pressure test. A pressure test will quickly indicate any leaks or weak spots in the system, as it subjects the radiator, hoses, hose clamps, thermostat and water pump to higher-than-normal operating pressure.
