What do I do for an overheating combine?
A- The first thing to always do is shut off the engine (use extreme caution to avoid burns as most coolant can reach 210 degrees F. and can spray out and scald you!!!). 1.) After the engine is cool, check coolant level. Every day a pressure cooling system can lose some coolant, and needs to be full to cool equipment properly. 2.) Check fan belt tension, if the drive belts are not tensioned properly the fan will not run at the correct speed. 3.) Check external radiator for blockage, and wash out as needed. Blocked air passages prevent proper cooling. 4.) Check water pump function, if the coolant can't circulate the engine will overheat. 5.) Check for a sticking or broken thermostat, the thermostat regulates the temperature of the engine. 6.) Check for improper coolant flow on the inside of radiator and through the radiator cores. A plugged core will also cause the engine to overheat. These tests will require help, possibly the aid of a mechanic. 7.) Check out ALL fan blades, ducting, louvers, shrouds, etc. All these items are required to keep air flowing in the right places for proper cooling. If everything checks out to appear to be in working order, check out the gauge for proper function, and replace as needed. 8.) Eighth & MOST important ALWAYS be safe as coolant can burn, fan belts & other moving parts can severely injure you & others. Safety starts & ends with each of us. If after all of these tests are performed and you still have a problem, call a mechanic. I hope I was able to be of help.
