What causes overheating?
Wes Grimes Question:  My engine overheated. What caused this and what do I do about it?Answer:  Overheating is caused by anything that leads to a loss of coolant, prevents the cooling system from getting rid of heat, or causes excess heat in the engine itself: -Coolant leaks (water pump, radiator, heater core, hoses, freeze plugs, head gasket, engine internal). -Weak radiator cap (does not hold rated pressure and allows coolant to boil over). Pressure test the cap to check it out. -Cooling system clogged (deposits built up in radiator or in engine due to maintenance neglect or use of hard water). Use a cleaner, then reverse flush the system to clean it out. A badly-clogged radiator may need to be rodded out or replaced. -Thermostat stuck shut. Replace the thermostat. -Inoperative electric cooling fan. Check fan motor, relay and temperature switch for correct operation. -Bad fan clutch. Replace if it is slipping, leaking, or loose. -Missing fan shroud (reduces cooling efficiency of fan). -Slipping fan belt. Tighten or replace the belt. -Too low or too high a concentration of antifreeze. It should be a 50/50 mix with clean water for best cooling. -Bad water pump (impeller eroded or loose). Replace pump. -Collapsed radiator hose. Check the lower hose. -Debris in the radiator. Remove bugs and dirt. -Late ignition timing. Reset to vehicle specs. -Restricted exhaust system. Check intake vacuum readings and inspect converter, muffler, and pipes. -Radiator and/or fan undersized for application. Increase cooling power by installing larger radiator and/or auxiliary cooling fan.
