Denso › Engine radiator

Ok-Energy5358 28 Jan 2026, 20:30

Rating 5.0

Leaks:

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.

Pros: zero leaks

Vehicle: Toyota 4runner

Mileage: 65000 km

Leaks:

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.

Cons: radiator leak, catalytic converter issue
