ok heres my setup....

small t3 .... oil cooled
2.5" mandrel piping
CCA 6" FMIC
greddy BOV
d16y7

alright so i had to wire up my fan to the lights so it would be on all the time to cool my coolant off because it was pretty much boiling in the resevoir tank and the radiator itself...

well now it stays cooled for around 30 miles of good around town driving and the needle will sit right in the middle of C and H.... well then the coolant vaporizes or something and i have to refill the radiator cause there isnt any in there.... ive put about 100 miles on my car and have had to add water 3-4 times because i was running hot... not close to H.... PAST H

am i missing something?

and im not using actual coolant..... im using just tap water.... would that make a difference?

 

definitely would help to run coolant.

 

head gasket?
check for leaks?

 

both are fine

 

 

Headgasket. Check it again.

 

have you removed the head at all? did u re-use the head bolts?

 

no the head has never been off..... the thing was running fine before i went turbo....

 

do a compression test. might have a bum headgasket (doesnt ALWAYS mix w/ oil) or the head is lifting.

 

i got the same problem
the hg doesnt leak out of boost but it lets air in the coolant when i go for a run
im gonna torque my bolts down +5 and see if that does it
