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

And don't put the oem radiator in (it sucks). A mishimoto is 2/3 the price, will last longer (it's not made of plastic at the top -- that's why the oem ones fail) and it will actually keep your engine a little cooler.

Pros: lasts longer, keeps cooler

Cons: oem ones fail

Vehicle: Subaru Impreza

Pros: Hasn't leaked at all

Cons: hole in the box

Vehicle: Toyota
