Step 1.
Start water pump engine (WP 0022). Check if water pump engine runs rough.
If water pump engine runs rough, troubleshoot Water Pump Engine Misfires,
Runs Rough, or Lacks Power (WP 0089).
WARNING
Allow engine to completely cool before handling any cooling system component or
hose. Failure to comply may result in serious injury to personnel.
NOTE
Step 2 will check for internal damage to water pump engine causing coolant to enter
combustion chamber. Do not pressurize cooling system with pressure tester for this test.
Step 2.
Stop water pump engine (WP 0022). Install coolant system pressure tester (WP 0478).
While an assistant starts water pump engine (WP 0022), check if coolant pressure
system tester shows pressure increase just after starting water pump engine.
If coolant pressure system tester shows pressure increase just after starting
water pump engine, replace water pump engine (WP 0219).
Step 3.
Stop water pump engine (WP 0022). Perform water pump engine compression
