Hello people. I have a friend that has a coolant leak somewhere, and I don't think it's the thermostat.(there are no signs of brown foam, but it could be internal and getting evaporated ) It basically will cost her a $1000 if it is the stat,over $900 of that is in labor. Now I can do it but the whole top of the eng. has to be removed to get at it. I don't want to do that if I don't have to, so does anybody any suggestions, or have any knowledge of this problem with this model? Peace!
