if you JB weld it it'll just crack beyond the point where the weld is applied. But it might hold you over till you find a new radiator.

Alright, just thought i'd try. Never had a radiator crack. Although, that may be a good fix until you can find a deal on one. Usually people MUST buy them, right then and there because their'* is shot and they need a new one. Maybe picking up one from a junkyard is a viable option. I'm sure a later year would be compatable, and the only thing that would vary [i think] is it would cool better if you picked one up from a Supercharged 3800.

Ya if you tell them you need one from a supercharged car it might work, but remember ssei'* only came after '92. A 92 radiator may not fit in an 87-91 bonne. I think if he finds one for a heavy duty it'll be fine, 3 core is plenty. That'* what i got in my car and it runs super cool even on 85 degree days.

An H-Body is an H-Body, man. Some exterior body parts changed, but other than that, they are exactly alike. I'm 99% sure a 92+ radiator would fit in an 87-91.

I've got the stock [whatever the core might be] radiator, and it stays cool in 110*+ weather. The stock radiators in our cars are fine, I am just saying that he can widen his search.. maybe save a few extra bucks.

I wouldn't be so sure. Even though the chassis was reused for 1992, the rad support may look similar (and be similar or the same in dimensions), it may not bolt up.

Hell, radiators even changed between the years for '87-'91. Unfortunately, I've got a slightly thinner, used 1990 (If I recall correctly) spec SSE radiator that was plucked off a family friend'* parts car. The original, '91-spec one was thicker.

a: try a local radiator shop. Think when I replaced the radiator in our '90 it was about $150. Looks like the crack was caused by flexing the radiator hose - JB Weld may be temporary. Secret is surface preperation though.

Plastic tank on son'* GrandAm cracked on top. I JB Welded it using quite a bit and going well past the ends and seems to be holding. Did use plastic pipe cleaner (for sprinkler pipes from Home Depot) for surface prep after cleaning and sanding.

Is that a metal Radiator? And have you owned the car seince new? Looks as if the Radiator has been replaced before... 91'* came from the factor with plastic tanks... That looks like metal.... Or am I wrong here? LOL
Howdy! It is metal and I have not owned the car since new; I've had it for just over a year now. :( Auto Zone has them new for about $300; is that the only viable option?
WTF??? $300... Woah... That seems a little steep...

A couple of questions..

Do you have 2 cooling fans at the radiator? Some of these cars had Heavy duty cooling... Its possible that you may have a 3 core Radiator...

Do you by chance have an Advance Auto Parts near you?
Yep! 2 fans and I live near an Advance!

Yeah, $300 seems pretty ridiculous. Maybe they messed up when looking it up. My sister went to a radiator shop to get one for her '89 LeSabre T Type (fellow h-body with dual fans), and it ran her about $130.
