DESCRIPTION
When performing a scheduled maintenance, you may notice coolant residue at the water pump weep hole. This condition can be a normal part of the
water pump seal break-in period. To confirm that this condition is due to the break-in period and not a faulty water pump, perform a cooling system
pressure test according to the following procedure.
REPAIR PROCEDURE
1.
Verify concern.
2.
Remove radiator cap and install pressure tester.
3.
Pressurize system to:
123 kPa (1.25 kgf/sq.cm, 17.8 psi)
Caution
Applying more than 123 kPa (1.25 kgf/sq.cm, 17.8 psi) can damage the hoses, fittings and other components, and cause leaks.
4.
Wait approximately 5 minutes, then verify if cooling system did or did not hold applied pressure.
^
If system held applied pressure, water pump replacement is NOT necessary.
^
If system did not hold applied pressure and the water pump is leaking, replace water pump.
