WARNING

Coolant may be very hot and under

pressure from engine operation. Ensure

engine is cool before performing

troubleshooting. Failure to comply may

result in injury to personnel.

CAUTION

Do not pressurize over 16 psi (110 kPa).

Failure to comply may result in damage to

cooling system.

(1) Pressurize radiator overflow tank, using

tester, to 15 psi (103 kPa).

(2) Observe radiator overflow tank for coolant

leaks.

NOTE

Pressure loss without external leaks

indicates engine internal coolant leaks.

go to step 7 of this fault.

(5) Remove tester and test kit from radiator

overflow tank.
