ok kool thanks for the help

 

yeah thats what i thought. but the good thing about that filler neck is i can see the fluid go through when the pump is actually working. we hit it witha hammer and it came on. lol.

i ordered the bosch intercooler pump so i should get that tuesday. should be an easy install. foes anyone had any bad or good experiences with the bosch pump?

 

so when my iat is at 60 andmy iat2 are at 100 to 120 id say my ic is not working right ??

 

Really I wouldnt worry about a 120* iat2.

 

i wish mine were that low. your fine at 120

 

really i thought the 2 numbers should stay a little closer together then that

 

Depends on your mods. If you are dual pass or bigger/second HE then that is pretty high. When driving on a 60F day my IAT2 would usually be at ~80F, that is with dual pass and opt b w/2.9 pulley.

 

My iat2's get to like 150 right now..i dont have my meth hooked up yet and im wating for my h/e so im crusing around with a half tuned tvs and 80's..lol

 

well im all stock so what should my iat2s be

 

I've heard as a rule of thumb, 20 degrees over ambient temp is a typical IAT2. Even for stock. But after a WOT pull tho... not too sure.

Found this too...

well mine seem to be all over the place so i think im going to put my new pump on that i have had for awhile now lol

 

im in the same boat. mine works sometimes and not others. i got the bosch replacement sitting at the shop waiting to go in. i was just waiting for my heat exchanger first.

 

yeah same here lol its been warm up here in cleveland and i seen my iats'2 hit 150 yester day so i need to get my pump on lol

 

On a different note... has anyone changed the coolant to more water than dexcool? Right now I'm running 50/50, the temps are fine, just wondering if I'd benifit from something like 75% water, 25% dexcool?

 

dont know lol

 

Yes you will. I run water and a bottle of chill charger.

 

ya sounds like ic pump too me tap with rubber mallet and run 75 water 25 dex oh ya and get an interceptor cuz repeated runs over 200 iat2s... kaboom

 

Water is actually the coolant, so running a higher part water will cool temps more. The dexcool is a lubricant and raises the boiling boint as well as lowering the freezing point. The IC system shouldn't get hot enough to boil, so that isn't an issue. You don't need much lubrication in the IC system either. The only thing you have to watch out for is freezing.

 

ok cool deffently going to run 75 water and 25 dex
