i just installed the zzperformance front mount heat exchanger. i took off the hose coming out of the right side of the stock heat exchanger and had it go to the front mount, and then from there to the inlet of the duall pass endplate. i would get iat2 temps of about 125-135 deg F, and now i am still getting about the same, maybe even a little bit hotter. going about 75 mph i see the iat2 temps of about 120 lowest ive seen was 117 on a 82 deg day.... is this normal?? maybe i have air pockets??? i was expecting to see lower iats..... what do you guys think

 

If you didn't bleed it out you have air pockets...

I bled mine for 2-3 days and it still wasn't fully bled. I went through about 3/4 of a gallon, just the front mount since I removed the stock one.

I bet I could have had a little more in the system if I never hit the damn cat and twist the front mount.

BTW, I hit a cat and all that happened was it bent. Didn't leak but twisted into the AC condenser and into the rad destroying everything.

 

^ Was the cat ok?

 

No idea. I went back to the scene after coasting home and it was MIA.

The next day when it got towed I had hair in the subframe holes

I honestly wish the cat died a cold death. Costs a lot of money to fix!

 

Lol, how fast did you hit it? Sounds like you were bookin it!

/threadjack

 

Let's just say fast enough to coast roughly 1/2 mile home with 3 turns

 

ok......well that really wasnt the response i was looking 4....... ppl r more interested in the cat then in the thread............lol

 

its gonna take awhile for you to bleed out the system. make sure you keep adding coolant.

 

make sure your pump is working. common problem. the only time i have seen iat2 temps that high is when my pump quit.

 

were in lovely florida.

 

ok well in 95*f ambient the highest i ever saw (keep in mind im a 2.85 and have a cobra) was 122, and that was after a good 3rd gear pull. i have had higher recently however my pump isnt co-operating with me.

 

And yes, keep adding fluid.

Every night when you get home and turn the car off, pop the hood and add more coolant until it fills up. The next morning when you go to the car, pop the hood and check the fluid. If it went down, add more till it fills up again. I did this every time I started/turned off the car. Seemed to work awesome.

 

well ive seen the iat2 temp drop.....but while idling it still gets a little hot.... as soon as i start moving it goes down..... like i saw yesterday 109 iat2 temps.... and would normally sit at about 113 while cruising.... at idle it still got up to about 130ish.....good mod tho.... never seen iat2 temps that low b4

 

The stock system should technically bleed itself if the surge tank is still there.

Normal. You live in a miami which is hot and humid...even in the winter.

 

It bleeds itself out over time.
