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 put a Denso radiator in my wife's car.

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

Pros: perfect fit, well packaged

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

I ordered a Denso radiator from RA earlier this year. Took my old radiator out of my truck before opening the new one (rookie move, I know). Well one of these fittings was bent/broken on the new one. Called every car parts store, mechanic, and radiator shop within an hour drive and no one had one. Someone finally pointed me towards a hydraulic shop and I had to have a guy there machine a new one for me. Been working without an issue. It was just crazy to me how difficult it was to find such a simple fitting.

Cons: bent/broken fitting, difficult to find replacement
