got all the big lines installed.. theres a brass elbow and a little black insert with a clear tube for over flow to the secondary surge tank.. does this go in the copper fitting and ten a hose over it ?

 

i don't totally understand what you're saying.... but the clear tube/hose should go from the option b tank to the top of the stock heat exchanger.. and the copper or brass (not sure which) goes into the stock heat exchanger, and then the clear tube connects to that

 

Little black insert goes into the brass fitting. Then the brass fitting goes onto your STOCK heat exchanger. Clear tube goes from brass fitting to small nipple on 2nd (option b tank) tank.

 

That's what I thought. So I'll see it through the clear tube. Thanks man.

 

Its an air bleeder so nothing should go through there. Thats what the black insert is for...to stop fluid coming through and only allow air.

 

ok i have a option b tank in my car and just wondering if that small hose connected to the heat exchanger to the opt b tank is spose to be pushing coolant back into the tank. It has always pushed coolant into tank and now has stoped just wondering

 

Its for air only. Either you restrictor fitting is missing or broken

 

Some coolant will bleed up through the restrictor.... that's normal.

What you shouldnt have is a steady flow of coolant going from the top of the stock heat exchanger back to the expansion tank.
