COOLANT PASSAGE
EXHAUST MANIFOLD
Coolant Recovery Tank, Recommended Installation
Fill the fresh water system as follows:
I. Remove the pressure cap from the manifold.
2. Pour a clean, antifreeze mixture into the manifold and allow enough time for the coolant to fill the
fresh water cooling system.
3. Start the engine and allow it to come up to its operating temperature. Monitor the coolant in the
manifold and add antifreeze coolant as air is expelled. Once all air is expelled from the system, fill the
manifold to the filler neck and install the pressure cap. Open the air bleed petcocks, each in turn, located
on the upper inboard side of the manifold to allow any air in that area of the manifold to escape. Close
the petcock securely.
4. Remove the plastic cap from the plastic coolant recovery tank and fill the tank with coolant halfway
between the ADD mark and the MAX mark. Replace the plastic cap.
5. Run the engine and observe the coolant's expansion flow into the plastic recovery tank.
6. Check for leaks between the pressure cap/filler neck and the plastic recovery tank. Stop the engine and
allow it to cool. Coolant should be drawn back into the cooling system as the engine's temperature comes
down. Check the coolant passage in the filler neck to ensure it is open to flow. Clean it with a heavy
piece of wire periodically to ensure it remains open. Once a season or more should you find it necessary.
7. Add coolant to the recovery tank, as required, to top off the fresh water coolant system and periodically
check to see that the manifold is full of coolant by removing the pressure cap when the engine is cold.
