AGREE WITH BOTH #1 AND 2
SOUNDS LIKE A BLOWN HEAD GASKET. ON THAT TYPE OF VEHICLE ITS BETTER TO REPLACE ENTIRE ENGINE, THE BLOCKS ARE ALUMINUM AND SLEEVES FLOAT, IF YOU NEED MORE INFO, I HAVE A TEMP SOLUTION FOR THAT ON EMAIL US MOBILMECHANIC481@GMAIL.COM
Is there a temporary repair
Loosing coolant? Overheating or coolant just looks "muddy"?? Ever changed out the coolant since YOU have owned it?
