It seems I need a new catchcan for the radiator, the mazda dealership says its like $127 or something for a piece of plastic.

Did any of you buy it off the dealer or did you buy aftermarket ones?

The only ones I found were here :

Anybody have them, any problems with them, which one is the best?

Thanks

 

Search for AST or Air Separator Tank - that's the name of the part. A number of vendors make them that are RX-7 specific.

Or just buy the AST elimination kit...Belive it's something like $35.00

 

Are you looking for a AST or the overflow tank? The overflow tank is infront of the right wheel. If it is the overflow tank you looking for, I'd think you'd be hard pressed to find a after market one that would fit in the stock location. Check with Ray Crow@

By the way, are you sure you need a new one? I've seen people over fill the tank and think it's leaking when it just draining from the overflow hole.
