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

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.

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

My first new car was an ‘82 Toyota Celica. I put 3 radiators on that car within 10 years. The OEM radiator had a copper core and plastic tanks, held onto the core with a crimped clamp all around. I don’t think that they paid much attention to expansion rates and coefficients of expansion of different materials when they designed these, and the seals would eventually give out and begin leaking.

Cons: seals give out, frequent leaking

Vehicle: Toyota Celica
