Cooling System Pressure Test

System Pressure Test
1. Remove radiator cap cover located under the
storage box access panel. See Chapter 3.
2. Remove recovery bottle hose from coolant filler.
3. Connect a Mity-Vac™ (PN 2870975) to radiator and

must retain 10 lbs of pressure for five minutes or
longer. If pressure loss is evident within five minutes,
check radiator, all cooling system hoses and clamps,
or water pump seal.
Radiator Cap Pressure Test
4. Remove radiator cap and test using a cap tester
(commercially available).
5. The radiator cap relief pressure is 13 lbs (89.6 kpa).
