OVERHEATING - blowing out coolant

1bigdoggie · 12-27-2019, 09:55 PM

Ever since I had the engine worked on for a complete valve job (new head, etc..) I have had an overheating issue. Have traced it down to COOLANT LOSS at such a rate that eventually the engine will overheat. The coolant is being blown into the overflow tank, and from there, after it fills up, it blows out the top and continues to do so until there is not enough coolant left in the system (down about 50 ounces or more) and then the engine overheats and pings the needle red.

Anyone know how this can happen? Why is there so much pressure build up to blow out all the coolant into the overflow and beyond??

ANY HELP is appreciated.
