I've got a JD 2640. The temperature gauge is going to red after it runs for a few minutes. The air cleaner restriction indicator is also on.
When I run it for a few minutes and the temperature gauge is getting to red, then I shut the tractor off, the radiator fins are not very warm at all. When I open the radiator cap and touch the coolant, it is warmer than when the tractor has not been run, but it's not hot.
I've put in new primary and secondary air filters. I put in a new thermostat. I also drained the coolant (opened the drain cock on the radiator and let coolant flow out), ran the engine for a few minutes while running water from a hose through the radiator, and refilled with a 50/50 mix. When I refilled, it only accepted 2 gallons, but capacity is supposed to be around 13 quarts.
What should I do next? Is there a way to tell if it is the water pump or if it is blockage in the radiator? Does the air cleaner restriction indicator offer a clue - or is there something else problematic with it? Is there any need to bleed air from the system - if yes, how?
Just hoping to learn from other people's experience. Thanks.
