STEP 3 CONTINUED
3.3 Per figure 3.3, route the open end of the
hoses toward the front of the engine where the 3/8”
NPT nipples were installed in step 1.2
3.4 Connect the hoses to the nipples with hose
clamps provided, see fig. 3.4.
3.5 Cut hose to length and install to heater with
hose clamps provided.
3.6 Cut and splice the in-line shut-off valve into
the supply line (which comes from the top of the
thermostat housing), in a suitable location like the
one shown in figure 3.6. Attach using two (2) hose
clamps. Confirm the valve is all the way open.
NOTE:
The in-line shut-off valve quickly converts
the heater into a summer time blower by preventing
hot water from flowing to the heater core.
3.7 Secure hoses with wire tires as necessary
to prevent rubbing against hot or moving engine
components. Wire tie the return hose to the air
cleaner bracket so it does not kink under its own
weight.
3.8 Using manufacturer’s recommended proce-
dure, refill the cooling system.
