I ordered this over flow to replace a small capacity tank. Just knowing the over flow is working holding that extra plus radiator is staying at the level.

I bought two, 1 for my 67 Cougar RestoMod & another for my restoration of a 77 Jeep CJ5. In both cases the fit and look was perfect. Easy to install. Quality product.

I used this in my '67, cars didn't have overflow tanks then so I had installed a plastic one that has some age and was looking crappy. This looks good and was easy to mount, much nicer than plastic and should last a long time.

I loved the beauty and function in my big block Camaro, I had to buy same product for my 1955 Chevy 210. Capacity holds more that most tanks, and O ring seal cap is quality. Polished tank look complete sitting next to radiator.

What type of hose can bend back up then bend over to the radiator without kinking? Does Speedway offer the hose to connect the coolant overflow tank back up to a top fill radiator?

Is this strictly an overflow catch can or does it also a recovery reservoir that will cycle coolant back to the radiator?

What is the spacing of the 2 mounting tabs? Center to center. I have a 49 Merc with the original flathead motor with a Weiland baby blower installed. I'm pushed for extra spacing for mounting an expansion tank. If the tabs are close enough together to mount to the wheel well on a flat spot this unit might help me out. If not, I might need to go with an old fashioned overflow bag.
