Water cooled 991's have ridiculous air pocket problems, the final solution was a
couple companies that sell vacuum bleed systems, you pull a vacuum on the cooling system,
then it has a valve you open to suck the coolant in.

Here's a couple, I've only used the Baum version myself.. The principle is simple..

I'll ask again. Are you sure the head gaskets are on the correct side?


I explained why this would be a problem but deleted it, I can't explain it.

Jake33

yes I'm surr they say front on them

Jake33

This is like my gasket with the tang on the bottom torwars front.

I changed my upper radiator hose so its lower.
thermastat is 160 degree . I bought a vacumepump from summit racin . Still hot

So.... when you fill water pump neck and radiator completely full and run the car is it pushing water out into the overflow excessively before it starts to overheat? Or when you go to check it is there now air in the system? If so does it smell like exhaust fumes?

Jake33

Seems like at 230 it will push out overflow
when it gets hot it does smell like exhaus . The exhaust is out the bumper so ur literally right by it

I do have regular water in it.
I also opened up front bumper to get air flowing vs just the 2" holes

Here is a video of my set up

Any issues with this ict adapter being out of the head?

Is this a possible cooling issue. I imagine it

I run the same adapter, no issues.

What I meant was does the water smell like exhaust gas, to see if maybe there is a head gasket issue.
Nothing in your setup is any different that lots of other setups that run perfectly normal temps. Tons of turbos are placed right where yours is. I could see your fan possibly melting a little under a long pull but maybe not lol.

No water doesn't. My leakdown check. Also was good and the system does hold pressure

Dang man... theres nothing left to check.....
It should be able to sit there and Idle all day long with that fan on

Jake33

Whst head gasket you recomend. I did run the btr22033. Boosted application
If I gotta remove the heads to check gaskets. I dont wanna do it again. If and one runs the btr 22033. Check the tang on them. Both sides should be between 2nd and 3rd head bolts
front side correct?
