1D-6 ENGINE COOLING

DIAGNOSTIC INFORMATION AND PROCEDURE

Checks
Check for a loss of the coolant
Check for a weak coolant solution.
Check the front of the radiator for any dirt, any leaves,
or any insects.
Check for leakage from the hoses, the water pump, the
heater, the thermostat housing, the radiator, the core
plugs, or the head gasket.
Check for a faulty thermostat.
Check for retarded ignition timing.
Check for an improperly operating electric cooling fan.
Check for radiator hoses that are plugged or rotted.
Check for a faulty water pump.
Check for a faulty coolant reservoir cap.
Check for a cylinder head or an engine block that is
cracked or plugged.
Checks
Check for a leak in the radiator.
Check for a leak in the following locations:
•
Coolant reservoir.
•
Hose.
Check for loose or damaged radiator hoses, heater
hoses, and connections.
Check for leaks in the water pump seal.
Check for leaks in the water pump gasket.
Check for an improper cylinder head torque.
Check for leaks in the following locations:
•
Intake manifold.
•
Cylinder head gasket.
•
Cylinder block plug.
•
Heater core.
•
Radiator drain plug.
Engine Fails to Reach Normal Operating Temperature or Cool Air from the Heater
Checks
Check to determine if the thermostat is stuck open or
is the wrong type of thermostat.
Check the coolant level to determine if it is below the
LOW mark on the coolant reservoir.

COOLING SYSTEM DIAGNOSIS

Engine Overheats
Loss of Coolant
Action
Add the coolant.
Confirm that the coolant solution is a 50/50 mixture of
ethylene glycol and water.
Clean the front of the radiator.
Replace any damaged components.
Replace a damaged thermostat.
Perform an ECM code diagnosis. Confirm the integrity
of the timing chain.
Replace the electric cooling fan.
Replace any damaged radiator hoses.
Replace a faulty water pump.
Replace a faulty coolant reservoir cap.
Repair the damaged cylinder head or the damage
engine block.
Action
Replace a damaged radiator.
Replace the following parts, as needed.
•
Coolant reservoir.
•
Hose.
Reseat the hoses.
Replace the hoses or the clamps.
Replace the water pump seal.
Replace the water pump gasket.
Tighten the cylinder head bolts to specifications.
Replace the cylinder head gasket, if needed.
Repair or replace any components, as needed, to
correct the leak.
Action
Install a new thermostat of the correct type and heat
range.
Add sufficient coolant to raise the fluid to the specified
mark on the coolant reservoir.
