plastic radiator crack, Burb

It cracked cause it wore out replace it with a new/rebuilt one and you get a warranty we have a couple of 90s era chevys and if we get a 150-180 k on a radiator were happy. There's not much to them

Not a Suburban, but the OEM radiator in the wife's 2000 Camry sprung a leak in the top tank 3 years ago. My replacement options were a new radiator for $500 from Toyota, or $110 from the local NAPA store. Opted for the NAPA replacement, installed it myself and it has been fine since. Never considered attempting a repair, though NAPA had a repair kit. The counter guy persuaded me that replacement was a better plan.

Twenty-four year old radiator wouldn’t have other weak spots? Replace!

Time for a new one. Modine makes probably 90% of all automotive radiators now and all are plastic tanked and all die after a while. New only.

I would replace it with an all aluminum one. Why rely on plastic end tanks with gaskets when you can have a welded one piece design for around the same price? Check if you have oil and/or transmission cooler lines going through the radiator before you order one.

Those patch/repair kits always seem to let you down at the wrong time.

Like the others said, fix it right.

seems almost all the radiators built in the last 30 years have gone to plastic caps. And seems like no matter who the mfg is, the life is somewhere around 100K miles or 10 years.

you've been lucky.



Fixes are a short term band aid. solution is a new radiator.

That's been my experience and virtually all my neighbors who keep vehicles very long.

If you have a "Summit Racing" store near you, I've found them to be the best place to get radiators.

The repair kits are best suited for people making a quick repair just to sell it. They usually don't last long.

I got a Vista-Pro replacement rad from Rock Auto when my 01 started leaking. I don't think they make all-aluminum for this application because you have oil cooler lines going thru the left side and trans cooler lines going through the right side.

*EDIT* They DO make an all-aluminum radiator that fits a 94 1500 burb, its $929 at Summit Racing. :E Now I remember why I didn't get one....

If you plan on keeping the truck now is a good time to replace all the hoses, t-stat, and rad cap. On the 01 the plastic overflow tank is pressurized as part of the system and ages out just like the radiator does, worth checking on your 94.
