AST tank...above, below, or even with filler neck?
Should I mount a new aluminum AST so that the cap is above the filler neck cap, below it, even with it, or doesn't it matter?
thanks

Mine is mounted at a slight angle below the filler neck. Its attached to my PFS SMIC. The previous owner did it this way. I'm pretty sure you can mount it where ever you want and it won't matter.

Yes... if the car is off, and you open the AST cap while its sitting lower then the filler neck, you will loose some coolant out of the AST. This is the only downside IMO.

No... it wont overflow at the filler neck if AST is higher, as there is no pressure and the AST has another hose going back into the radiator. Coolant would go there, but it cannot push all the coolant already in the radiator out of the filler neck so.... nothing happens in this scenario
