Cooling System Bleeding
on Fiat Twin-Cam

TO
AVOID ENGINE OVERHEATING CAUSED BY COOLING SYSTEM
AIRLOCK, PLEASE EMPLOY THE FOLLOWING PROCEDURE WHEN
REFILLING THE COOLING SYSTEM:

1. Raise front of
car and support safely on jack stands. It must be high
enough so that the radiator filler neck is the highest
point in the cooling system.

2. Place heater temp
lever in the ""heat"" position.

3. At cylinder
head tee (see Fig. 1) detach the hose that runs down to
the thermostat.

4. Loosen the same hose at the
thermostat, but do not remove. Rotate the hose on the
thermostat 180 degrees, forming a filler spout (see Fig.
2).

5. Pour coolant into the hose until it begins
to run out of the cylinder head tee.

6. Replace
the hose on the tee and tighten the clamps.

7.
Continue slowly filling the cooling system through the
radiator until it is full.

8. Leaving the
radiator cap off, start the engine and allow it to run
until the lower radiator hose is very warm and the
temperature gauge reads near the center of the scale.
This indicates that the thermostat has opened.

9.
Lower the car, top off the cooling system and replace
the cap.
