I am having trouble with overheating. I have removed the thermostat and this has helped but not fixed the problem.

It is a Belarus 90HP (an old one)

The water is pouring out from under the radiator cap

MarkOsborne,

There are two possibilities regarding your overheating problem.

The most common problem is the radiator cap, itself. It's very possible that your radiator cap is faulty. Start with replacing the radiator cap. It's cheap enough, and it may solve the problem entirely.

Radiator caps are designed to maintain a small amount of pressure on the cooling system. If the cap fails, the coolant will quickly boil.

You could also have a blown head gasket. High pressure exhaust gasses can then escape by the head gasket and enter the cooling system. You'll know if you have a blown head gasket immediately after replacing the radiator cap.

Stop in if you need further help.

Joel ....

Could also be improper coolant, such as plain water.

Or a clog in the system. Best to have the rad and block power-flushed at a rad shop, but you could try this:

Put quality cooling-system cleaner in the rad. After a few hours of running you'll have to get it all out, by draining just the rad (unless yours has a block drain too). So that requires several drain-refill-run cycles. ....

Had it fixed today. Looks like it was a mix of things, clogged radiator, poor quality coolant and the thermostat had been removed. All is well now, although I will find out tomorrow when I commence slashing.

Thanks for all of the suggestions.

Cheers
