WARNING! A cooling system can have up to 15 p.s.i.
when hot. Only repair or check when the ENGINE IS COLD or personal injury can
result. Always have the vehicle under inspection
on level ground, in park with the emergency brake on. Always wear protective eyewear,
gloves and necessary clothing before inspection or work begins. Never crank an engine
over when anyone is near the battery or engine. Always have an operational fire
extinguisher close by, obey all first aid instructions in the event of an injury.
Never stand in front or behind a vehicle when cranked over or running. When engine
is cranked over keep hands and clothing away from rotating components.
The vehicle's radiator is the component that removes heat from the engine through
thermal heat exchange. It is usually located in the front of the vehicle under the
hood. The engine creates heat from the internal combustion that continuously occurs
inside the engine, this heat is transferred to the engine coolant, then circulated
through the thermostat then to the radiator. Inside the radiator there are many
small tubes with cooling fins attached that allows the coolant to be cooled and
then returned to the engine in a continuous cycle. Radiators are mostly made of
2 plastic tanks and an aluminum core.

Step 1 - Identify Radiator and Cooling System
Components (under hood)
The thermostat housing is where the thermostat resides, it is connected
to the radiator upper tank. The system is filled and checked at the radiator cap.
The radiator is held in place by the radiator holder brackets and is usually
near the top radiator tank. Some radiator configurations may vary in appearance
but the concept is the same.
Step 2 - Disconnect Negative Battery Terminal
Make sure the ignition key is in the off position, loosen the terminal
pinch bolt and disconnect the battery terminal (gloves suggested). Anytime you perform
repair work like this it is a good idea to disconnect the battery to avoid electrical
short circuits. Always disconnect the negative battery cable to avoid a short to
ground and NEVER let the wrench contact to positive side of the battery. Make sure
the battery is clean at all times. If corrosion exists rinse battery with water
(hose) and sprinkle with baking soda to naturalize the remaining acid.
Step 3 - Drain Cooling System
Locate the radiator drain valve, turn it counter
clockwise to loosen. On some cars there is a protective plastic splash guard that
may need to be removed to access the radiator drain valve.
