The radiator has an overflow tube that is 1/4 " and the coolant tank is 1/8". I haven't found a good way to connect them yet. The chrome is beautiful and the price is awesome !

I have a 94 Dodge Dakota with a 3" body lift, the lift requires removal of the fan shroud, the stock coolant overflow tank mounts to the shroud. The stock system requires a non-pressurized tank. Mounting and tubing are no problem and the filler neck on the radiator has an overflow provision. Is this the right tank to use to replace my stock one?

We run a sealed system in our modified. No where for water to go as the engine heats up. Would installing an expansion tank help drop the temps? Are we having the issues we are because we are creating to much pressure by not allowing water to escape?

What size tank would I need for a 72 chevelle 350 w/ a/c? Would I need to change my radiator cap and does this unit allow for coolant to go back into the radiator upon cooling down? Finally, does it come with all parts needed to install? Thanks

I need to know how many inches from top mounting hole to bottom mounting hole. I have a 1923 Ford coupe with a Aluminum Radiator for 1932 Ford with Small Block Chevy. I was just wanting to know if this 17 Inch Stainless Steel Expansion Tank will mount to the side of this radiator. That's why I was asking how many inches from top mounting hole to bottom mounting hole. If this won't mount can you tell me which on will work? Thank you
