Hi everyone! Trying to find as much help possible online to help me with a problem im having. Today my jeep completely overheated every time i drove it, it would get all the way to hot. When i idle and stop i hear a fan in the engine turn on and get real loud and thats when the gauge starts to get real high, then i start driving and it goes back down to middle. I try turning the heat on to take some heat off the engine it doesnt help at all. Last year i flushed the coolant, and about a week ago i filled the resevoir tank with coolant because it was completely empty and topped off the actual radiator with coolant because it was a little low, and i made sure to push the car to get most bubbles out. Today after going home with the gauge all the way on high it must have bubbled over and exploded out because i opened the hood and there was coolant sprayed everywhere all over the engine. What caused this??? Its also super hot out so that dosent help! any ideas please ! its a 2006 commander v8
Matt, if you're still around.
And you want as much help as possible. Let's start from the beginning.
After the engine cools. Pull out your dipstick and check your oil.If it looks like chocolate milk you're done.
If it doesn't. Then you might be okay.
Second is to wash off all the antifreeze under the hood. Wash it all off with clean water.
Then you're going to remove the bleed screw on the upper radiator hose on top of the motor.
If you didn't do this the last time you changed out your antifreeze. You may have created your own problems. That is a step that cannot be skipped over.
You can't just push the motor to burp out the system. Like you stated earlier.
Once that bleed screw is removed. Then refill everything until antifreeze comes out of that bleed screw hole. Refill your reservoir and refill the radiator. Put the cap back on the radiator when antifreeze comes out of the bleed screw hole.
Reinstall the screw. And then once all that water is dried up from washing everything. Now fire engine back up and wait and see what happens. Start looking for leaks and cracks. once you know for a fact there's no air in that system. And it still has overheating problems. Then you know you've got some things you can start checking one by one.
If you know that your oil is still good. And I was in your shoes. I would get a new thermostat and housing and install it. Before you do everything else, I just mentioned. That way, at least that part is covered. And it's cheap to do. Make sure you don't put that thermostat in backwards. If you can't find any leaks when pressure builds up. You might be losing your antifreeze through your heater core on your dash. It can be a slow leak.Some folks just can't smell antifreeze when it comes out.
