Pressure Cap Test
Tools Needed:
9S8140 Cooling System Pressuring Pump Group
One cause for a pressure loss in the cooling system
can be a bad seal on the pressure cap system. Inspect
the pressure cap carefully. for damage to the seal or to
the surface that seals. Any foreign material or deposits
on the cap, seal, or surface that seals must be
removed.
The 9S8140 Cooling System Pressurizing Group is
used to test pressure caps and to pi check the cooling
system for leaks.
To check the pressure cap for the pressure makes
the pressure cap open, use the procedure that follows:
1.
Remove the pressure cap from the radiator.
WARNING
If the engine has been operated and the
coolant is hot, loosen the pressure cap to the
first and let the pressure out of the cooling
