Ok so I have dual pass I installed Here is the diagram I used.
Also I have a LFP Dual pass heat exchanger and It doesnt have the bleeder on top so I have just let it run and tried to bleed it from the bleeder on the bottom. Well my temps are at 170 sitting and drop to 140 driving I know that aint right.

 

how are ur laminova core hook up ?

 

im pretty sure the middle is the out and did u swap the cores ( might be wrong can some one chime in)

 

Make sure the IC pump is working and there is no air in the system.

 

Cores are like so the top and bottom are out and the middle is in. Thats how its done here https://www.cobaltss.net/forums/show...l+pass+install

 

Its air and a bad pump. My iddle was 80deg above ambient with my pump working. Swapped. Pump now I'm at 50 deg over ambient the more air I work out the better cooling it does

 

nah bro air if anything just replace the pump not to long ago with a brand new lightning.
