2007 model 3203 started it up and in 5 min. gauge on red , radiator feels cold and it is full . Does this indicate a bad water pump or could it be a valve stuck ? 885 hours and so far over 3,000 in repairs . Bought it used with 500 hours , not a happy camper

Get some way to monitor temp of water in engine and around the water pump. May just be gauge. Hope you will be happy soon.

I'd drain the rad. fluid and see what that is like.. look for plugged radiator too. Check out the thermostat..

Yea I would suspect a stuck thermostat in the closed position, or your water pump isn't working.

A infrared temp gun is very handy in situations like this. If it is over heating in 5 minutes, I would point to the thermostat. I have seen water pump impellers move on the shaft and not pump the coolant adequately. But you would have to put it under a load before it would over heat.

You can check the thermostat for operation. Pull it out and put it in a pan of water on a stove.

Get a new one, auto parts stores may physically fit, check your owner's manual for temp and put it in. You don't get proper circulation without one......so the story goes. On my Fords they do, Bransons haven't had the problem, JD 4230 100 hp required 2 stats and had to use JD OEM style.
