300M, Greenville, NC, September 13, 2009, 02:36

Hello, I own a used Chrysler 300 M with 133,000 miles on it. It recently started running out on me... I kept water in it and always pulled over on the side of the rode once I noticed the temperature gauge started to rise, except one day I was late for work it began to run hot and I continued to drive despite. I was stubborn and was attempting to make it to work on time. Nevertheless it overheated extremely until it cut off on me white smoking from the exhaust and hood extremely bad. I was on the side of the rode and it would not start back up even after cooling off..I ended up getting it towed to a local repair shop and he did a diagnostic of the heads that sit on top of the engine. I was quoted 1400 to replace both heads. My question is what is the potential that this price will creep up once the engine is broken down or that I might need a new motor. I just feel I may have done extreme damage to it and that it may have seized.

    It is always a possibility that other items will need to be replaced once the cylinder heads are removed. An engine that is badly overheated can cause damage to the oil control rings. The labor to replace the engine is about 10 to 12 hours.

    Yes, much damage could have been done. Mine has overheated a couple of times, the result of electrical radiator fans that were toast. New fans, water pump and even radiator (as it was cracked) and the car's been running fine. In my case, I've used Mobile1 synthetic oil since it's second oil change. Running fine as it approaches it's 11th birthday and 240,000 miles! Only the engine, starter and alternator fuel injection system are original in this car. All else has been replaced.

    my wifes 2000 300m has 130000 miles and the ac needs replaced but we are not sure to put $1100 into that car.
    How long do you think an original timing belt should last on this car? should we just trade this car in?
    thanks!!

    We had this exact thing happen with our 300M and it took forever to diagnose the problem. The dealership finally found the problem and it ended up being one of the dual fans that had gone out. With one fan working it would over heat and then keep going when it cooled off. We were able to do the repair ourselves by replacing the entire unit and purchased a new aftermarket one from an auto parts store, one that had a lifetime guarantee. We were glad we did because a couple of years later the same thing happened. They said it went out again because of an issue with wiring compatibility and that seems to have been worked out because the second one has been in for several years and is working just great.

    do you happen to have the cost of that dual fan and manufacture? im having the same problem, had them replaced a couple of years ago but it now happening again. the dork at the repair shop told me the second should come on when the AC is energized but i didnt believe him. one of the fans is clearly out and the temp goes up to almost half when it gets hot outside, not comfortable with that at all. tnx
