Hey Guys,

I have a 2007 SE V6 T4R that is about to hit 100K very soon. I know, just barely breaking in the car now. I plan on doing a coolant flush, power steering fluid flush, brake fluid flush, and changing the radiator hose (upper and lower). Cooling system is great, no leaks or any signs of heating up. Previous Owner did change the water pump and thermostat at 70K. Do you think I need to change the radiator? or is this too early? Thanks.

If you have money to burn, sure.

But not really needed until it's leaking. An old, but good OEM radiator is still better than the majority of aftermarkets you'll find.

ehh, don't really have money the burn. just wanted to do preventative maintenance. don't want to be stuck on the side of the road with the family in the car.

I like where youre going though, radiators have a finite life, especially the aftermarket ones. I blew a head gasket on my old acura thanks to the rad, just had a feeling the aftermarket rad wouldnt make it to the next flush and fill but since it wasnt leaking i left it alone. woulda coulda shoulda.... getting 12-15 years out of an oem is common, i think you may be leaving the comfort zone.

once you replace it, i'd think of it as a maintenance item every other flush and fill, 6 years may be about all you get, and since they will often have a lifetime warranty just trade her in..

do be sure to pressure test your radiator at regular intervals for piece of mind, once the tanks crack you need to replace it pronto.

replacing an oem radiator without a problem is like replacing a fender that isn't dented because "maybe it will start to rust one day", the logic is the same.

oem radiators don't have a finite life span, they can, and usually do, last longer then the vehicle does, so leave it a lone and don't fix what is not broken.

even if you bought an oem Toyota replacement radiator ,it isn't made as well as the original, that is because anything made today is trying to be made at absolute minimal cost by the lowest bidder and they sure don't care about making them last forever anymore, in fact they "try" to bake in a finite lifespan on everything made today to sell more parts
