Air in the system needs to be bleed, Id order the Y so it works better. Ur Iat2's is 27 over iat during cruise? Yeah thats pretty high but u have air in the system so that may be why.

 

i can sit there an watch air bubbles come threw the hose back up into the opt b tank, so is it something that time will take care of ? is there anything i can do ?

 

Why do GM do it this way? Cheap and because no one cares I guess. The best for the cooling is gentle sloping hoses, no kinks and no t's; not always possible.
and why do I mention it? Because folks need to hear why things cost more. And you have to repeat things many times for folks to hear it.

seems to me, you didnt hear or read the info right the first time, and in fact argued the option B deal when yours didnt work. so.

I would check connections, it is entirely possible there is a leak somewhere...

 

powell thanks for your input, i checked for leaks hose clamps on everything are nice an tight.

It seems like the coolant does not want to go into the t fitting for some reason from the opt b tank. If you look at the pics, the tube is full right up to the T, an it shallows out
and the air bubble is there.

 

do you have a restrictor (.040) in the bleed line to the HE? Any extra FMIC or stuff like that?

 

Why would I call, I don't even know what they're selling. How many sells are they losing to competitors because it's a non-functional website?

 

no dual pass, ottp fm h.e and yes the restrictor is in the line(no coolant is coming out of it) so i routed it as so .... http://www.zzperformance.com/miscftp/HE%20routing1.jpg

 

Good point. We don't do e commerce off our web site and it does not work very well. But the products we make are listed. and If folks wont email we will probably lose the sale. Thats unfortunate, but at the moment I cant fix the web site. Thats not my expertise. Back to making parts.

 

Check with Paul P, your tuner, out there, maybe he can help you. The OTT FMIC is an issue ZZP published pictures of the cores a long time ago and maybe the restriction in the core means you have to be patient and wait for the air to get out. My guess is, the cooling with the stock HE would be as good alone as it would be with the extra FMIC and the air entrappment may well be less. Good luck with it.

 

ok thanks powell ill have him check it out

 

if anyone else has any input please feel free to help me out

 

Is your pump working? No kinks in any of your hoses?

 

yea pump is working no kinks anywhere

 

the air bleed line does go on the stock HE right? idt there is one on the ott one?

 

yea bleeder line is on the stock h.e, how doi know if its working correctly tho ?

my issue seems to be the fill hose isnt full when it hits the "t" u can see in the pics

 

and the reservoir is full, right? so something isnt working right, possibly the pump. are you sure its running?

 

When you were filling with coolant, did you make sure there was coolant sitting in the t-fitting before attaching the hose to the Opt. b tank?

I use the same proceedure for filling my opt. b tank as I did when my cooling system was stock.

1. Fill with coolant until it bleeds out of the top of the stock heat exchanger.

2. Attach new fitting with 0.040" bleed orfice to top of stock heat exchanger.

3. Continue filling until coolant is visible in the top of the T-fitting.

4. Cap/plug T-fitting, start car (I used some extra straight 3/4 hose, and plugged the top).

5. Re-check T-fitting.... If there is coolant still visible, attach Opt. B tank and fill tank. If not, fill and repeat steps 3 & 4.

 

thanks staged ill double check but yea it was full after i ran the process ... ill re try it

 

Ok. Sounds good.

 

u know the system is properly bled when there is nothing but coolant running through that clear hose to the tank

 

by clear hose u mean ? bleeder hose or fill hose ? ... i cant get the fill hose to fill up all the way to the "t" thats the problem.... its like its too low or sumthing but its level

 

the bleeder hose coming off the h/e

 

yea its black tho so i cant see whats going on inside of it

is there supposed to be any fluid in the bleeder line ? im getting mixed answers as i read other threads.

 

that needs to be changed then... after all without the filler neck i dont think theres any other good way to know that the pump is working other than seeing fluid move through that line. also u know ur pump is working by turning the key on and hearing the buzz of the pump

 

for some reason my pump never turns on when i turn the key to on , it only runs when the car runs... ever since day 1. i know it works cuz before my iat temps were 20* above ambient stock.

i can see coolant moving through the fill hose (clear, snake like hose in my pics above) but there is an air bubble in it as u can see in the pics.

so should there be a stream of fluid through the bleeder line ?
