Denso › Engine radiator

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

I just got a new Denso radiator off of rock auto for a Tacoma. It didn't look much better than this. Had a hole in the box from shipping. Installed. Hasn't leaked at all.

Pros: Hasn't leaked at all

Cons: hole in the box

I put a Denso radiator in my wife's car.

It was packaged very well and arrived completely undamaged. It was a perfect fit.

You should absolutely fix, but $900 is steep from the quoter. Buy a quality rad (denso, nissens) and have it installed by a competent mechanic for $300 max.

Get a Denso on Rock Auto for 130 and replace it yourself. Watch a YouTube video on how to do it and save yourself a bunch of coin.

Pros: save yourself coin

Vehicle: Toyota 4runner
