Hey we have a Massey ferguson 4840 and i seem to be having water temp issues. tractor gets hot when worked. watch temp gauge climb quickly. Water pump?? who would be the best person to ask? message back if you have any ideas.

change the thermostats to 160 degree,blow out the rad.and tighten the fan belts. don't worry about the water pump until it starts to leak.you do know cummins wants a gold bar for a water pump. try and figure out if your engine is running hot or maybe just the gauge screwing around.

You could have a badly plugged off radiator on the inside. If antifreeze has not been changed much or maintained even more chance of that. Drain a little antifreeze, remove the cap, and on some radiators you can see the core, some you can't.

Blow the radiator out first check actual temp then look at thermostats and check belt of course.

Is it actually boiling over or is the guage showing high temp. I would get it up to temp and drain some coolant and check the temp. Thermostats would be cheap to try as said clean radiator. Does the tractor have a viscous fan or a solid drive. Could be a bad viscous clutch. Otherwise you might have to get radiator boiled out at a radiator shop

thanks all for the ideas. will try some of them and check some when it gets warmer out.

very probable that you have internal crud on the tubes inside, jd makes a rad and cooling system flush that uses oxalic acid with water under load to dissolve the crap, then a flush and neutralizer . it works well, and or lots of old timers would drop the coolant and fill the system with water and some tide for 2 hours of work, drain and flush and refill with 50/50 coolant. most coolant has less than 5 years life, and when the additive package and inhibitors go the cooling system suffers like you describe. maintenance of cooling systems is often neglected. cummins has test strips in single packs that can tell you your additive status and ph, as well as coolant freeze point, use them, they also make an additive to replenish the coolant midstream of its life.

We had one that after changing thermostats, removing radiator and getting recored we found out it had a broken water pump impeller.
