TC29DA Overheating

Problem solved.

I swore I cleaned out the radiator sufficiently - but I was wrong.

I've periodically cleaned out the radiator fins because they get really gunked up when I mow my field with the rotary cutter. I have a front end loader that I never bother to take off. I sometimes have it extended all the way up when I'm in the field, but I usually just have it at a "normal" height in front of the tractor - this tends to brush off all the seeds and fuzz to get them airborne just in time to get sucked into the radiator. I guess they got so compacted in the fins that my normal cleaning wasn't enough to get all the accumulated gunk out.

I had to remove the battery, oil cooler, and fan shroud; and, I had to use both water pressure and air pressure to clean out all the crap. After spending a few hours working on that, the tractor runs at a normal temperature again. Thanks for all the suggestions.

Thanks for responding back! I use a long air wand that is bent at a angle at the end to blow air from the back side several times a year.

Glad you found the problem.

I sure am glad you did that instead of pulling the water pump. Of course, I was taking you at your word that you had cleaned the radiator fins. I'm really happy that others suggested you be a little more conscientious about that job.:thumbsup:

On my tractor, the hood has a vent screen that is supposed to catch all fuzz from weeds. Actually, it does a pretty darn good job. However, around the hood is a rubber seal that may get old and stiff. Under my radiator was some foam that got wiped out by acid from a leaky battery as early models did. When I fixed my battery shelf, I pulled out all that rotted foam and stuffed some carpet padding in its place. With an Optima battery, I no longer have acid, but some lint still gets through the hood and into the radiator. About twice a year, I blow out the collected lint around the edges and then use a hose nozzle to reverse flow water through the radiator. By doing it in the late summer and then again in early springtime, I've never had a problem. I'd suggest you look for air leaks around your hood closure and try to stop any large leaks. The fine screen on New Hollands hoods does catch 90% of the lint, but some of it does get through and build up over time.

My TC33d has the older 12 fins per inch radiator that has the screen right in front of it to stop most of the debris. After swinging the air inlet out of the way, the screen pulls up and out to clean it. I still blow the radiator out from the back when I pull the screen. Per service bulletin 3/03-T5, after serial #G039046 tractors had a radiator with 8.5 fins per inch and NO front screen installed. It was their attempt to have less plugging of the fins.
