INSTALLATION
Reverse removal procedure.
Whenever coolant lines have been disconnected it is necessary to bleed air from the system as follows:
Disconnect coolant heater outlet hose (12) at elbow (10). Add coolant at surge tank until coolant spills
from both elbow and hose. Reinstall hose on elbow without allowing air to enter either hose or elbow.
Tighten clamp and continue adding coolant until full level is reached in surge tank.
After engine has been run to raise coolant pressure in system make visual check of all hose connections
for leaks.
