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.
New core 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.
The National Automotive Radiator Service Association (NARSA)
recommends that motorists have a seven-point preventative cooling
system maintenance check at least once every two years. The
seven-point program is designed to identify any areas that
need attention. It consists of:
- a radiator pressure cap test to check
for the recommended system pressure level
- 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
- By performing regular checks, NARSA
radiator and cooling system specialists can help motorists
prevent problems, emergency repairs and/or replacements,
effectively saving the consumer time, trouble and money.
