vs
Engine radiator KOYORAD or OEM Toyota
Reviews
For your turbo Baja, [Koyorad](https://ebay.us/m/yadARd) is the creme de la creme.
Pros: creme de la creme
Vehicle:
Subaru
I went with a Koyorad radiator from rock auto and then I also replaced the inlet and outlet hoses with OE. A new OE radiator cap, too. Subarus are fairly sensitive to cooling system parts, so for any mechanical bits (cap, water pump, thermostat, etc) I highly recommend spending on OE.
Pros: highly recommend spending on OE
Vehicle:
Subaru Forester
Just dealt with the same thing with my AP1. The plastic to metal seam fails eventually and causes the leak. I got the Koyorad OE replacement and it was around $100 and took an hour to install.
Pros: OE replacement
Cons: plastic to metal seam fails
Vehicle:
Honda S2000
Koyorad if you want good OEM fitment and a fucking drain bung plus good cooling even for modified engines (we’ve put a bunch of the larger alloy ones into rx7’s)
Pros: good OEM fitment, good cooling
Cons: price higher than Fenix
Bout to hit 300k tomorrow on my 2012 and I’ll I’ve ever replaced is the radiator and a transmission sensor. All the pulleys are oem
Vehicle:
Toyota Tundra
Mileage: 300000 km
im steady at 75°C (167°F) with stock Ka, koyorad radiator, fanshroud and oe/oestyled clutch fan. and iirc, a stock nissan thermostat. hottest ive seen was like 89°C (192°F) and that was sitting in traffic on a hot summer day. idk how im running so cold lol.
Pros: steady at 75°C, runs very cold
Vehicle:
Nissan
I went with the Koyorad on mine. Everything fit perfectly, no modifications needed, which hasn't always been the case for me
Pros: perfect fit, no modifications
Ive had my car enter limp mode multiple times on a high 80 track days. Coolant temp would spike to the 3/4 marks. When I upgraded the radiator to a koyorad I never had issues again.
Pros: no more limp mode, stable coolant temp
I got the thicker Koyorad and managed to get it to fit with some redneck engineering, but it was a squeeze.
Cons: difficult to fit with AC
My first new car was an ‘82 Toyota Celica. I put 3 radiators on that car within 10 years. The OEM radiator had a copper core and plastic tanks, held onto the core with a crimped clamp all around. I don’t think that they paid much attention to expansion rates and coefficients of expansion of different materials when they designed these, and the seals would eventually give out and begin leaking.
Cons: seals give out, frequent leaking
Vehicle:
Toyota Celica
