Reddit reviews TYC 1140 Compatible with MAZDA Miata 1-Row Plastic Aluminum Replacement Radiator

When they get brown and get kind of a spider webby look to them, they plastic is decaying and becoming brittle. It will crack any time, probably while you're out on a long drive and get the car really warmed up.

New OEM Koyo (Koyo made the factory radiator and are also a good aftermarket manufacturer) are only about $100 currently $75 from Amazon. Super simple DIY repair.

It says TYC but many many Miata owners have ordered that one and it comes in a Koyo box, has Koyo marking on the part, and is exactly like the OEM radiator in every way... except not brown...

I actually just saw this one today. Since your in oregon I would say the one plus is that he replaced the top. Another is the reasonably low miles. As for the negatives as stated before the radiator will need to be replaced very soon as it is very brown. You can get this one as it a OEM replacement but for very cheap. It is koyo brand so it is a reputable brand and you get it for 90.00 shipped. While doing that I would suggest doing the main coolant hoses as well which will be around another 100.00. I would suggest taking the stock rims and using that money towards a good set of wheels that arent 17s. With that you would be at 3000 with around 200.00 of parts to replace right away so I would ask 2700 once you take the car for a spin and go up from there because you can negotiate knowing there are things needing to replaced already. Unless there are any other noticeable things that you see wrong with it once you take a test drive 2700-2800 would be a fair price in my eyes. Also be sure he has replaced the timing belt and water pump as this is the mileage where it should have been done pretty recently.

Note that a LOT of owners wait until closer to 100k for TB and water pump replacement if there are no issues. Owner's manual for CA says 105k, everywhere else is 60k. Same exact belt. But doing it at 60k won't hurt anything. Read here: https://www.miata.net/garage/timingbelt.html

For radiator get the $78 TYC radiator on Amazon. It is direct fit--even for your 1993 according to multiple forum posts I've read. Amazon will disagree but you can ignore that. Here's one recent comment about this--see #24. Transfer the rubber/metal mounting bits and fans from old to new and bolt it right in. If it comes with auto trans cooler connectors on the bottom (I'm assuming you have a manual) just leave them alone. Replace your coolant hoses if needed. Reuse the spring clamps if you have them. Total cost including a little antifreeze should be around $100.

I am preparing to do a timing belt/water pump replacement myself. All my research says to get a Gates belt. I've seen total kits on Rock Auto before but for something you'll have in the car for 60-100k miles why not spend a bit more and get things with good reviews? Get the seals separately if you can't find a kit that has a Gates belt. Most people replace the water pump when they do the TB. I'm hoping to find a water pump with a cast impeller rather than stamped and spot-welded.

EDIT: FlyinMiata has a good reputation and they have a kit: https://www.flyinmiata.com/na6-big-nose-timing-belt-kit.html - worth consideration.

I know it's not all aluminum, but what do you think?

Got any links? This was the cheapest I could find.

Amazon is telling me those won't fit my car. Are either of these the correct one or do I need to put something more specific into the search bar?

Amazon says these are built for the automatic gearbox models.
