so a week ago my car was dumping coolant into overflow tank( expanding it until fluid leaks out) and i replaced head gasket over this 3 day weekend and it seemed fine for a day until today wen it started doing that again and my heater going from burning hot too cool.... so im like whats going on. thermostat maybe? i have never replaced it before.... also my car surges idle. any advise is greatly appreciated

 

by the way i did headgasket saturday 1-19-13 and i had my head checked and milled / resurfaced too

 

o and a brand new ARP stud kit was used. torqued to 60 ft pounds and in the right order

 

Maybe your block is warped?

 

would a bad thermostat cause this too happen??? or am i wrong?

 

bump....

 

you should check your block, my a6 recently over heated and the head is currently off. i plan on taking the block out and getting it checked out and maybe resurfaced. but i was wondering if any of you honda diy wizards know where i could get a headgasket to help compromise for the shaved metal off both the block and head...because wouldnt that increase the compression ratio?? any info will help

 

i have never over heated it past 3\4 on temp gauge... idk about previous owner but ya... my car ran perfect b4 i took head off but just sent coolant too overflow tank.. i have never replaced or checked thermostat,,, could that cause that???

 

will thermostat cause this?????? or not?

 

yeah, the thermostat can be it. it might not be opening once the operating temp is reached.

 

You can check to see if the T-stat is working by letting the car warm up and check to see if both hoses are hot. This would mean the t-stat is opening. They are not that expensive. I would just replace anyways.

 

it was head gasket. i just re did it.... good too go.. now my car still surges for an idles too.. any ideas why??? my car came with a aftermarket 68mm throtle body.. maybe i should have tps adjusted differently from stock or what???

 

what does "my car still surges for an idles too" mean?

what rpm does it idle at?
