cool enough to touch with bare hands. Slowly
loosen cap to first stop to relieve pressure
before removing completely.
Test Radiator Cap:
1. Remove radiator cap and attach to D05104ST Tester
using appropriate adaptor as shown.
2. Verify with the applications specification manual that
the correct cap is being used.
3. Pressurize cap to cap’s specified pressure.

Gauge
should hold pressure for 10 seconds within normal
range if cap is acceptable.
4. Remove the cap from gauge, turn it 180
°
, and retest
cap. This will verify that the first measurement was
accurate.
Test Cooling System:
NOTE: Engine should be warmed up to test overall
