Typical example
1. Stop the engine and allow the engine to cool.
Isolate the electrical supply to the engine. Loosen
the cooling system filler cap (1) slowly to relieve
any pressure. Remove the cooling system filler
cap.
2. Clean the cooling system filler cap (1) and inspect
the seal (2). If the seal is damaged, discard the old
filler cap and install a new filler cap. If the seal is
not damaged, use a suitable pressurizing pump to
pressure test the filler cap. The correct pressure is
stamped on the face of the filler cap. If the filler
cap does not retain the correct pressure, replace
the filler cap.
