2004 Mitsubishi Outlander AWD, over heats when idle/stopped, cools down when driving. Added antifreeze 2 weeks ago, problem fixed until yesterday when started heating up again during idle, antifreeze leaked, haven't found any leaks. Help!

only clickin i can think of that would make idling erratic is the timing has become out. and the pistons are hitting the valves. this would click or tap and eventually go bang. would not recommend reving or driving it till the timing has been checked.

see the picture. God bless you

If you know about timing belt driven water pumps.. you know that you have to reset your timing on the engine. If you think you can. Tear it down.. replace the pump. And go onto the internet and find that engine and ask for timing marks.. reset them.. and all will be fine.. hope this helps.

I am having the same problem but it only happens to me when the car engine is cold. This does not happen when the car has been on for a while. My solution is that I warm up the car for about 20 minutes before driving and my car works fine.

Added to my problem, when I press the gas, it asks like it's choking and I have to press through it, flooring the gas, to which it accelerates too much. It's ok when no in traffic. Also, when I stop the car idles really low and acts like it wants to shut off.

fan clutch could be bad if it doesnt have electric fans. thermostat could be stuck shut. water pump may be bad s the impeller inside can come loose from the shaft the belt drives. dont drive until fixed as any new motor noise is sign of potential internal motor damage and may lead to engine failure.

If you added three gallons of coolant you must have a leak somewhere. Those motors were notorious for intake gasket leaks. Take a good look at the corners of the intake where it meets the cylinder head. Check the oil and make sure it's not milky. Usually when the intake gasket goes it seems to leak externally but it's possible it could leak into the engine and end up in the oil pan which will prove to be disastrous if you continue to run the motor with that oil in it.

Check the IAC valve...or sometimes known as an electronic choke. That valve is how your engine gets air when the throttle body plate is closed. If the valve is stuck due to malfunction or carbon build up then it will cause that problem, and give you a rough idle at best.

TAKE A PEEK UNDER THE HOOD IN THE FUSE PANEL FOR THE FUSE AND RELAY FOR THE COOLING FAN. IF THE FUSE IS BLOWN THEN REPLACE IT. IF YOU SUSPECT THE RELAY TO BE BAD THEN TEST IT BY SWAPPING THE FAN RELAY WITH ANOTHER ONE WITH THE SAME PINS ON THE BOTTOM. MAKE SURE IT IS THE SAME SIZE AS WELL. HOPE THIS HELPS.. PLEASE KEEP ME POSTED. THANKS FOR AN HONEST RATING AND FOR USING FIX-YA. GOOD LUCK

Yes, it sounds like the timing belt has broken, you need to have a Mechanic install a new one.

your window motor and regalator need to be replaced
