Radiator leak??

My current setup in my 69 camaro is an aluminum radiator with electric fan and a catch can attached to the fan shroud. I have the overflow hose coming from the neck down and it zig zags to the catch can. My radiator is leaking coolant out of the cap when the coolant heats up. I replaced the cap, another 16 lb cap, and it still leaks. Anybody have any ideas why coolant leaks out from the cap when I have a catch can?

I know I could just let is spit out what it doesn't need and it will eventually run at that level but I would like to know why this is happening.

Thanks in adavance.

Re: Radiator leak??

Does your catch can have a breather hole to allow the expelled water to displace the air in the catch can? (Can you blow through the overflow hose into the catch can without resistance?)
I assume you have checked your zig-zagging hose for kinks..

One option, although you shouldn't have to, is to use a recovery type cap. The upper seal of these caps will prevent expelled water spilling from under the cap providing the water is able to flow through the overflow hose into the catch can.

Re: Radiator leak??

No, there is no breather hole. The hose isn't kinked. Good point on the breather hole. I could always make one and see if that helps. I might try to reconfigure the inlet on the tank so I can just run the hose right down into the tank rather than zig zag back and forth.

Re: Radiator leak??

The raditaor if over filled will spue out coolant till it reaches the correct fill level on marked on the side.
A catch can is there because of scrutineering requirement at tracks fo doest spliil on the track creating dangerous conditions...
In some places it is now manditory to have on the road because of enviromental issue with thr glycol.
If you want to convert...I tryed a few yrs back and didnt work as meant to...did bother to find out why......a modern presure system where the raditor is full all the time, the access hot goes to a resorver (not a catch can) then when cools down gets sucked back in you need a special radiator cap, AND I think a special type of neck on the radiator.
Just fill the radiator up to the factory marks on the side of the radiator..there are 2 one "hot" the other "cold"..
Or fill it right up, catch the ecess in the catch can, mt the catch can....dont top up the radiator
problem solved

My Spelling is not incorrect...it is creative
