Wait until the temperature is below 50 C
(122 F ) before removing the coolant system
pressure cap.
Failure to do so can cause personal injury
from heated coolant spray.

carbonate and water(or a commercially
available equivalent).

to be operated without the cap for this
process.
Operate the engine for 5 minutes with the
coolant temperature above 80 C(176 F) .
Shut the engine off, and drain the cooling
system.
Fill the cooling system with clean water.
Be sure to vent the engine and aftercooler
for complete filling.
