Owner reviews for engine radiator

my 2005 4Runner Limited 4WD V8 that I bought one year ago with only 55k miles on it (well maintained time capsule), was just fine. Zero leaks from the radiator or anything. At 65k miles I went ahead and replaced the radiator with a Denso unit.

I figured going from a life in SoCal to southeast Texas summers would tax the radiator. Plus, 55k miles in 20 years, and now I’ll put about 20k miles a year on it, would likely make the original radiator go pop at the most inconvenient time, surely.

Put a koyo rad in it and it’s been good to go.

I got a Koyorad and 0 issues with overheating with hard driving! Coolant stays at operating temp no matter what.

I got a Mishimoto with zero issues and fitment was spot on

If you go aluminum Koyo is the way to go.

koyorad on my 400hp Focus and never had over heating issues.

I went with Koyo. CARid was the best price at the time. Been 7 years and no issues.

I had a 2019 from october '24 till late november '25, in that just over a year it was in at the dealership twice for repairs that if it hadnt come with a years warranty from the JLR dealer I bought it from it would have cost me thousands, first it was the right radiator with a leak which needed replacing then an issue with the cat.

My mishimoto radiator sprung a leak after 1.5 years in my F150. So good luck.

My first non warranty repair on my B58 540 was a $3k radiator replacement. That was at about 60k miles.
