Shutting down before it overheats or as soon as you see it is overheating will usually prevent significant engine damage. Bad head gasket symptoms include white smoke coming from the tailpipe, rough idle, and oil in the coolant. If your Wrangler is run for too long of a period while overheating, the head gasket may blow. It does this to relieve the pressure on the cooling system before lasting damage can occur.

If any part of this system fails, your Wrangler will eventually overheat. Radiator Hoses– Connect the radiator to the water pump and engine block.It is needed when driving at lower speeds. Radiator Fan– Your Wrangler’s radiator fan pushes extra air onto the radiator when the engine coolant gets too hot. Radiator– Pulls heat from the coolant before it cycles back into your Wrangler’s engine.Thermostat– The thermostat opens up once the engine reaches operating temperature and allows coolant in.The coolant starts in the radiator, enters the engine, pulls heat out of the block and heads, and returns to the radiator to be cooled again. Water Pump– Your Wrangler’s water pump pushes the coolant through the entire system.Your Wrangler’s cooling cycles engine coolant from the engine through the radiator. If your Jeep Wrangler is overheating, the first thing you should do is check the coolant level. A blown head gasket, engine block, or cracked head are much more expensive than a thermostat or water pump. Ignoring an overheating engine can lead to serious engine problems.
