Perkins 4.108 overheating

Hi anyone have this problem? I have a Diesel Perkins and it is overheating. The water in the header tank disappears and can''t find where it is going! Have replaced thermostat and checked all hoses and the head and cannot find a leak. The oil is fine no water in it or oil in the water. Engine seems to run fine but water disappears almost as soon as you start up the engine. Is that disappearence normal? please help me! I am out of things to try..thanks...

Suggest you check out your heat exchanger. If it hasn''t been maintained, it''s possible for the fresh water(header tank water) to escape through the heat exchanger tubes.
A low water level in the fresh water supply will surely result in high temps as the fresh water supply is the engines only way to get rid of heat.

Heat exchangers deteriorate if the zincs have not been maintained. Once a leak develops between the salt water (raw water) tubes and the engine coolant, heating problems are sure to follow.

Remove the heat exchanger and have it checked out by a radiator shop. If they are near salt water, they are probably familiar with heat exchangers and their maintenance.
Fairwinds,
Jim

In addition to the heat exchanger, the exhaust manifold is bathed in fresh water. There could be a crack inside the manifold that is allowing the fresh water to go right out the exhaust. You can follow the tubing that comes off the tank to get an idea of the flow thru the manifold.
