resurrecting a 2002 600xc.
idles good, runs good, unless I really get on it for a few seconds and it starts to bog and coolant steam comes out of the pipe through all the leaks and kills the motor. the owner replaced the head gaskets without success and gave up. ended up parking it for a few years. I wonder if he got the heads torqued wrong. or a crack. strange how its only an issue under heavy load. preasure build-up pushing coolant past the gaskets?
