I installed the Max Redline FMI. I have coolant comnig out of the cap which is rated for 15psi i think. i dont understand where i could have pressure building up b/c i have the dual pass which should make it fow easier. i also have the "stu" mod, so maybe the extra coolant? i dunno if it leaks while im driving but it def leaks when its parked for a little bit after im driving. any ideas?

 

Only thing that should cause pressure in the system is a kinked or blocked hose.

 

did you flip the cores when you did the dual pass install?

 

yess

 

I Have the same problem i cant figure it out

 

its an open vent system?! i was thinkin it might be the weight of the extra coolant but i didnt have this problem until a couple of months afterwards. it drips enough to make 5" diameter puddle after i stopped running the car! ill check my hoses when i do my build this winter. since it seeps out slowly, i might just put a higher psi limiting cap on it.

 

with my CXR fmhe, the cap is rated at 5psi, and i've never had a problem with it leaking.

 

do you have the "stu" mod?
