Engine radiator KOYORAD or OEM Toyota

I bought a Koyorad radiator for my 2003 Toyota Sequoia and worked out perfect!

I refused to install anything but a koyorad

My all aluminum Koyorad radiator is a far superior unit than the factory original.

I run the Koyorad 38mm radiator on my NB, with just regular Prestone green concentrate and distilled water 50/50, and OEM Mazda cap and thermostat. Coolant temps stay in the 190's at all times. It very rarely gets above 200 except on the hottest summer days, usually when sitting in traffic.

Another vehicle the rad got low and the stream pretty much melted the top where it connected to the hose. New rad was on backorder and I needed a car so I cut the melted but off at a clean angle and attached a chunk of ABS pipe using high-temp JB weld which I reattached the hose too after it set. I regularly checked it over the next 1-2 weeks until the shop got a new rad in and had no issues.

I placed the thicker koyorad in there and fixed a lot of issues, together with hood vents helped me getting my drift car cool.

I have the koyorad myself, bought it used. Spend some time sealing the nose to force all air through the radiator and you'll never have an overheating issue naturally aspirated.

Koyorad. Their fit and finish is OEM level.

One of the best replacement radiators for sure but you’ll have to get an external transmission cooler for it to work as the Koyorad doesn’t have an integrated transmission cooler that autos use.

When I ordered a koyorad I didn’t get this in the box. I sent back what I got from them it was all dented and didn’t fit.
