    2005 mustang 4.0l v6 sohc. shelby gt350 replica. i have a coolant leak that seems to be coming from behind the water pump on the left side of the car (or right side if your looking at the engine bay) at first i thought it was the water pump and or the gasket. i replaced both and still i have had this leak. i have heard that it may be a crack on the lower thermostat housing BUT it seems that one thing in common that people have experienced with that issue is that the leak only occurs when the car is running... thats where i differ, on or off coolant pours from my engine. i also had thought that it could be the head gasket.... but i have not experienced smoke from the tail pipe and my oil seems to be just oil not a mix of coolant and royal purple... i have checked all the hoses and all of them seem to be in order. can anybody help me im STUMPED and this being my only car at the moment i need a fix

    woah, that sounds like a major problem. i wouldnt run it if its leaking coolant though, it would be horrible to overheat the engine.

    my suggestion would be to get it towed to a shop.

    sorry I couldnt be of more help

    thanks for the reply guys. i put a new gasket on the water pump yesterday...the one i had gotten with the new pump was not good apparently. that stopped the leak for the most part while the car is off still slowly drips but not from the same area and not 100th of the amount it was with the bad gasket. i think it going to be the housing with the symptoms i am experiencing now but if any body else has this problem i found both upper and lower housings for about 50$$ on partsgalaxy.com. hopefully ill save a few people money. it looks like i made the mistake of jumping to conclusions and replacing the water pump before i found the leak for sure.... stupid me. but thx again guys ill defiantly be back next time i have a problem witch probibly wont be all that long knowing mustangs reputation ha ha

    Interesting, I have had this drip for a week now! I going to take a better look at the thermostat housing.

    Thanks!

    glad i can help another tip i can add is use needle nose pliers when taking the sensor off the housing i just pulled it off with a screwdriver he damn thing shot out and got lost. ford wants 7 bucks for basically a paper clip luckily i found it the next day when i had more light but be careful. good luck my friend
