- a radiator pressure cap test to check for the recommended system pressure level
- a thermostat check for proper opening and closing
- a pressure test to identify any external leaks to the cooling system parts; including the radiator, water pump, engine coolant passages, radiator and heater hoses and heater core
- an internal leak test to check for combustion gas leakage into the cooling system
- a visual inspection of all cooling system components, including belts and hoses
- a system power flush and refill with car manufacturer's recommended concentration of coolant
- an engine fan test for proper operation
5 Most common radiator service procedures
Flush and repair. The radiator is removed from the vehicle, cleaned externally using a powerful spray gun and flushed internally. It is then pressure tested, inspected and repaired as needed.
Clean and repair. In this procedure the radiator is removed from the vehicle, cleaned externally and flushed internally by immersion in a specially formulated industrial-strength cleaner. It is then flushed a second time, pressure tested, inspected and repaired as needed.
Rod-out and repair. The radiator is removed, cleaned externally and flushed internally by immersion. It is then pressure tested, inspected and repaired as needed. One tank is removed and a rod is inserted into each tube to remove debris. Once complete, the radiator is reassembled and tested.
Newcore or recore. This technique brings a radiator up to or as close as possible to its original operating condition by using restored existing parts in combination with new, rebuilt or unimpaired parts. It always requires the installation of a new core.
Plastic radiator tank and gasket replacements. In this procedure the radiator is removed from the vehicle and placed in a special fixture to detach the damaged tank and/or gasket. The tank and/or gasket is replaced with a readily available new or restored part. Afterward, the radiator is reassembled and tested.

Did You Know?
Ethylene Glycol/Polyethylene Glycol "GREEN". Tried and true, this type of anti-freeze is still standard after almost 70 years. Modern ethylene glycol anti-freezes have several additives to protect, clean, and lubricate your cooling system.
Non-Toxic Radiator Coolant. This anti-freeze does not contain ethylene glycol or polyethylene glycol (both acutely toxic). These engine coolants are, however, still toxic but only in larger quantities and over longer periods.
Extended-Life Anti-Freeze "ORANGE". In most cases, this is simply an ethylene glycol anti-freeze with one or more carboxylate additives to prevent corrosion of the cooling system. These engine coolants should make your car radiator and cooling system last longer.
