John Deere 5045 Problem: Engine Is Overheating.

The engine of John Deere 5045 E tractor overheats after about 15-20 minutes of operation. What causes can cause this problem and how to fix it?

Engine overheating is almost exclusively a cooling system problem. So let’s put the engine aside for a moment and look at the radiator.

First, a word of caution: Never try to open the radiator cap when the engine is hot. The coolant is pressurized, as well as being very hot, and can blow the cap off while stinging you from the hot steam. We’ve seen radiator caps fly through windows, onto people, and into the air – just don’t.

Next, make sure the radiator actually has coolant in it. After all, an empty radiator cannot do its job. Do not use tap water to fill your radiator as it is often full of minerals that can clog it and create even bigger problems. Instead, use a 50/50 mix of the proper antifreeze with distilled water.

You can blow out the radiator fins with compressed air if they are dirty or muddy. Dirty fins prevent the radiator from effectively lowering the coolant temperature, but be sure not to bend any of the fins while cleaning them.

If basic troubleshooting like the ones we’ve listed here doesn’t fix your problem, it’s time to call in a professional. Be sure to keep a list of everything you’ve tried so that you have a good idea of where to start.
