NOTE: Water is not required for testing.
Activate pump and pressurize engine cooling sys-
tem to 34 kPa (5 PSI).
Wait 3 minutes and check if pressure drops; if so,
verify all testing components.
– If kit components are not leaking and pressure
drops, verify all external jointed surfaces, tem-
perature sensor and the O-ring between the
spark plug area and the engine cylinder head
cover. If none of these components are leaking,
there is an internal leak and it can be detected
with Bottom End and Top End testing.
