    My 2008 Explorer radiator failed on its own. I later noticed that my fan will always run trying to keep up with the heat generated. I also had to keep topping coolant. On making a little research, i found out that its a common problem with 2006 thru 2008 ford explorer and so many people had replaced their radiator. The cost of doing this can set you back almost a thousand bucks. I did replace the leaking radiator along with the reservoir and the AC evaporator but i did something which put paid to the radiator ever busting again. i found out that the radiator cap is a very important part of the cooling system and its actually very important to the life of your radiator. I found out that the vapor return valve was stuck in the closed position. All i had to do was remove and gave it a thorough wash working the valve up and down. I later found out that my first radiator got busted due to a failed radiator cap which was not allowing excess vapor or steam back into the reservoir i.e. my radiator could not breath. So give your radiator cap a good wash today and you can save a lot on replacing your radiator.

    The problem started when I would hear a loud revving sound while driving. This would usually start after I've been driving, come to a stop then started driving again. It sounded like a jet engine. I would also note that my temp gauge would turn on and the light would go to "HOT" for about 20 secs then come back down. I did a little research on line and noticed others with the same problem and they ended up saying that it was a radiator problem causing the fan to go into overdrive to cool things down. I went out to check my radiator and sure enough it was almost bone dry and the coolant was almost all gone. (I had just topped these off 1 month before). Never saw any leakage which is why I never suspected the radiator. I've had the radiator replaced 3 times already and it looks like I'll be going in again tomorrow to have it done again.

    Same as others..radiator has a small leak. All is still running fine. Replace plastic radiator at DEALERSHIP!! Next thing you know the engine overheats and water runs out. We get it back to the DEALERSHIP! They replace the thermostat. It is bad they say. Then it overheats again and my wife has to call the DEALERSHIP! who sends out a tow truck and provides us a rental car. Now the issue is a defective radiator they say. I think the old thermostat and the new plastic radiator were the problem. Why didn't they really check the thermostat and radiator? The service rep tech said this is a common problem with the Explorer so if he knew that why didn't he check it out thoroughly. I had a previous Explorer, 1997, that was just great. Yep, they saved weight at my expense and over $1,500 dollars and personal time...glad I wasn't on a trip far away from home. Please pass on to others.

    I recently had my third radiator put in by the dealership. When I got home this morning I noticed it leaking already!!! The dealership tells me this is an issue with this the 06. Of course it always happens after the warranty runs out. At some point you would think Ford might find a solution for the problem. If this keeps up I will have spent enough for a nice down payment on a new vehicle!!

    noticed high revving after stops, looked it up on line changed the coolant cleaned the reservoir changed the radiator cap and thermostat noticed it was still leaking a bit finally had it start going into "hot" on heat gauge by the time I took it to the shop the thermostat housing was leaking as well as the radiator had the radiator replaced and the thermostat housing. Be sure to check not just the reservoir but the radiator coolant level Radiator repairman said its typical of Ford Explorer. Had a 95 Explorer in the past ran it over 170000 never had these issues only changed batteries starters and the alternator

    Trouble light, and Temp. gage spiked, pulled over to side of road ... white steam from engine compartment, and that famous smell. Leak from top of engine (2008 Explorer XLT, 4.0L V6), oh no, not simple hose or radiator ... my free road service from AMEX towed truck to my friend's shop. Half expecting "junk the truck" verdict. Turns out the plastic thermostat housing cracked, replaced both upper & lower housing, told my friend ... go hog wild, flush the system, new cap (it was getting crummy)' hoses, thermostat, antifreeze ... $500.00 later (cheap with the hoses for the Aux. heater in the back, I had a virtually new cooling system. I FORGOT THE RISK YOU UNDERTAKE WHEN YOU FLUSH THE COOLING SYSTEM ON A 100,000+ mile vehicle. Oh well, now the radiator leaks, so what's another couple of hundred. Ordered the radiator thru my friend, but put it in myself, don't want to abuse the friendship too much, plus I fix all his computers ... so I know what's coming.
