JD 4320 compact. I have the low heat problem when the tractor idles. I replaced my water pump about 7-8 years ago with the std replacement. Didn't realize/know that they make a high volume water pump. It has like a 2.62 dia impeller versus the 2.0?? maybe. If I ever replace it again i will put in the high volume pump. If anybody changes out there water pump you need new bolts because they are they torque turn setup. Later.

I forgot one other thing, Maybe you have a air pocket in the heater circuit. Later

Sorry for the info but my tractor is an older 4000 series. Disregard the above on the high volume water pump.

Got a great chance to use the cab heat today...blowing about 12" of powdery snow.
Heat works fine! In fact, since I was wearing insulated coveralls, I had to turn it down.
I hope the AC works as well!
