Radiator Cap Inspection
Check the condition of the top [A] and bottom [B] valve
seals and valve spring [C].
If any one of them shows visible damage, replace the cap
with a new one.
Install the cap [A] on a cooling system pressure tester [B].
Wet the cap sealing surfaces with water or coolant to
prevent pressure leaks.
Watching the pressure gauge, pump the pressure tester
to build up the pressure until the relief valve opens: the
gauge hand flicks downward. Stop pumping and measure
leak time at once. The relief valve must open within the
specified range in the table below and the gauge hand
must remain within the same range at least 6 seconds.
Radiator Cap Relief Pressure
If the cap cannot hold the specified pressure, or if it holds
too much pressure, replace it with a new one.
Radiator Filler Neck Inspection
Remove the radiator cap.
Check the radiator filler neck for signs of damage.
Check the condition of the top and bottom sealing seats
[A] in the filler neck. They must be smooth and clean for
the radiator cap to function properly.
