When we first got the car (sls) it ran fine but then it started to overheat. so we thought it was the headgaket so we bought this stuff called thermaseal and we flushed out the system and did what it said on the can. did not over heat when we let it itle. heres the thing it will not over heat when u sit in park and have it at 2,ooorpms for 5-10 min the temp gage stay halfway but when you drive it for a min or so down the street it would overheat. so we replaced the rad and looked at the water pump but the water pump was fine. filed up the new rad and tryed again soon as we would go down the street it would heat up and fast. i have no idea what it could be. anyone have any ideas? thanks[/quote:7e7504e4ee]

pressure test it for leaks, stop throwing parts on it, since you have probally overheated it to much, you probally have done damage, the head bolts have probally striped out by now, sorry to say

if no leaks are found, probally the head gaskets are damaged(headbolts)
