Is there information here or anywhere else on the net that would provide an interchange list of parts for an Eunos Cosmo? My son has developed a small leak in the top tank of his stock rad and is looking for a replacement. The local dealer is useless as we are in Canada and they don't acknowledge the Cosmo. I'm from the Mazda MX6 world and only have knowledge of donors for the 626 and MX6. I'm thinking possibly an RX7 of the same generation and engine family or possibly a 929.

The car is a 1991 Cosmo with the 13B Twin Turbo engine.

Any direction is appreciated as he doesn't really want to repair it... just replace it with a metal rad. Thanks in advance.

 

Mazda didn't make any equivolent for the Cosmo or RX-7.

I don't know if any RX-7 radiator would fit, but you might try checking the japanese regional section...when it comes back.
