hey there,
I own a 2004 GTP, just bought it in February and it all was working well until Good Friday, i was driving and i saw that my car was running really hot. so i pulled over into a parking lot and saw that the engine was smoking (thinking it was just from going through a lot of puddles) well it turns out that my coolent has been pouring out. i found out where it has kind of been leaking from and its around where the top 90 degree elbow is. i know what to do to fix that, my problem is that i smelt a sweet smell from my exhaust...
i have been reaserching the hell out of this car and i can not come down to the conclusion if its a head gasket or a intake manifold. i dont have any coolent in my oil, there was no lack of power because i had to pour a bunch of coolent in the rad to get to a better location so i was moving pretty good. i've started the car cold with coolent in it and waited a while to see if it would smoke white, there was nothing of that. the car seems 100% just that i can smell the sweet smell.
i talked to a mechanic and explained what was going wrong and he said that he never worked with a 3.8L S/C but he said it could be both. He told me to drain all that Dexcool crap and put the green coolent in, thats the only help he gave me.
