With a turbo setup coming together, I figured it was a good idea to upgrade the cooling system. Over the fourth of July last year, I upgraded to a new radiator in the Miata. I didn’t want to do any extra work later, so I upgraded other related things on the way.

The engine bay gets pretty roomy when you take out the radiator and fans. I flushed out the old system using a cleaning product. I should have done it sooner. It needed it.

The old and new. I upgraded my 240Z with a Koyorad radiator and I was pleased with the quality. When I was looking for the Miata, I found that Koyorad was making a new thinner version that performed just as well as their older performance radiator. I went with the new one.

The new radiator could accept the factory shroud and fans, but I decided to upgrade those parts. I figured I’d do it eventually and it would be better to do the work when the radiator was out. The shroud and fans are part of a kit made by Flyin’ Miata.

Nearly finished . I replaced the hoses with silicone pieces and used Breeze clamps to hold them in place.

I’m glad I swapped out the radiator. Eventually, I’ll reroute the coolant to make the most out of the system. It’s been doing great on the street.
