Head Warped after 6 months (more than 10,000 miles) since we attended thermostat replacement.?

I have a Honda Accord 2002 V6, which showed an unusual temperature reading about 6 months ago (about 10,000 miles before). I say unusual because it went to the high end only when car was stopped for a long time (such as in a drive through with engine on).



We had the thermostat changed immediately, but in July (4 months later) the temperature began to show similar symptoms and took it to radiator shop and they replaced the radiator. For another 2 months, it looked like problem was solved, but after that again the temperature started to show strange reading, the same unusual heating only when car is completely stopped.



Recently, after 6 months of changing and fixing (after more than 10,000 miles) the Check Engine light has lit up and we took the car for verification and they say we have a miss fire code from cylinders. They check the engine and see the head is warped.



Insurance company does not want to pay for the damage because the coverage is only for engine itself, not problems related to cooling system. But we did change everything related to cooling system and still the car was presenting ubnormal readings. Also, the insurance company say that the head was already warped from the begining when we first took the car for thermostat change (6 months ago, 10,000 miles before the check engin alerted). Is this possible to happen? can a car be warped half year ago and not show a miss fire code in the computer, or should it have shown us the miss fire code back then?



We are upset with the insurance company becasue they are just telling us that they are not saying they refuse to fix, but they do not either say they will pay for the damage. Strange part is that they are not clear in their answer, like if they know something and just waiting to see if we are capable of knowing it or not. They just say we need to present an evidence of failure that is not related to the radiator or thermostat.

You may already know this, but a warped head will not cause your engine to over heat... so all of the problems you have had were not related to the warped head, but the warped head was cause by your over heating problems. My first questions is did you ever pour cold water into your system while your car was hot? If you did, that would defiantly cause your heads to warp or crack.

As for your insurance company, they have lot of lawyers working for them... you may need to get one too if you really think that they owe you. Technically I think they have point.

As for your car.... because you said it would over heat when you stopped it makes me think it is a problem with your fan. The reason your car would be ok while it was moving is because air was getting in to cool the water in the radiator. When you stop the fan is what keeps the iar going over the radiator to keep things cool. You may need a new fan clutch or pulley. Also check your belts, something may be slipping. The only other thing it could be.... is your water pump going out or the valve is not opening to let water into your engine. It is easy to tell by starting your car (while it is still cool), and then open the cap on your radiator. The water level should be full. Once the car gets warm, the valve that lets the water into the engine should open, and the water level will appear to go down. If your car starts to get hot and the water level never goes down... change the valve, try it again and then if the valve didn't work change the pump.

Unfortunately your engine will never run the same with a warped head, if it runs at all. You will need to get the head changed out or replace the engine.

Hi, I would talk to a factory Rep. from Honda. I am sure they will help you all they can. I know they do not want this negative problem with their cars.Good Luck
