COOLING SYSTEM PRESSURE TEST
1. Remove the coolant bottle cover.
2. Remove pressure cap
q
and pressure test the cap
using a commercially available pressure tester. The
pressure cap relief pressure is 13 psi. Replace the
cap if it does not meet this specification.
WARNING
Never remove pressure cap when engine is warm or
hot. The cooling system is under pressure and serious
burns may result. Allow the engine to cool before
servicing.
3. To test the cooling system, connect the pressure
tester to the cooling neck
w
with the correct adapter.
4. The system must maintain 10 psi for five minutes or
longer. If pressure loss is evident within five minutes,
check the filler neck, radiator, hoses, clamps and
water pump weep hole for leakage.
