placing strain on the hoses, and be securely clipped to prevent accidental damage
and chafing.
Initially fill the fuel system by turning the ignition on to operate the electric fuel pump.
Loosen the bleed screw on the top of the primary fuel filter/water trap and close when
fuel begins to flow clearly (no bubbles). It is rarely necessary to bleed the injection
pump or injectors upon installation as the engine will already have fuel in it from the
engine run in and test procedure.
10. Coolant
Prepare coolant mix of 50% clean tap water and 50% antifreeze.
Fill the engine cooling system for the first time through the header tank filler cap on
models 30 & 40, and through the exhaust manifold filler cap and then via the header
tank on model 50. Start and run the engine for several minutes to dispel any
remaining air bubbles, with the pressure cap removed.
N.B. After running the engine for the first time, monitor the water level frequently as
trapped air bubbles may be expelled. Top up the system as necessary
.
Ensure the top header tank connection goes to the small hole connection on the tank.
