ACDelcoGM Genuine Parts 21499 Radiator

2001 GMC Sierra 1500. Fit perfect and great price

I had to go to Rockauto Parts to do a look up on the part number. Then went to a GM parts book to be surethe number was correct. Good fit easy to install. THanks!!

Bought this to replace the leaking OEM radiator in my 1999 GMC Sierra 1500. I try to use Original parts as much as possible due to the fact that they fit better and seem to work better. I researched this part to make sure that it was the correct one. I personally have never had the Amazon recommendations be incorrect, but I know it happens by reading the reviews here on Amazon. Do yourself a favor and make sure the part you're ordering actually fits your application. Only issue I had with this radiator is that it doesn't have a drain petcock in it. If you look at the photos of the part, it shows what appears to be the outlet for a petcock, but it is just molded into the side tank and is plugged. Not really a big deal, just something to be aware of before you buy. Part fit like I thought it would, also price dropped $25 right after I bought mine, so those that buy now are getting it for a much better price.

The replacement Radiator fit just like the original in a 2000 Chevrolet Silverado 1500. The replacement radiator also came with new upper & lower mounts, a nice addition. The only very small downside is the there is no drain plug on the replacement radiator, but there are other ways to drain radiator.

Mechanic who installed said was perfect fit and exact as replaced one. Description said it wasA/C Delco brand but could not find any branding on it. Bought from warehouse at substantially discounted price.

Love OEM radiator, only problem that it was to small. Even though it said that it fit my 02 Tahoe. This one is a 24" one and mine needs the bigger one, 34".

it fit great works great just no drain plug but i knew that ;) fast delivery

My truck was over heating at idle, I checked every component in the cooling system. Everything was good, 16 years original radiator which did not leak, after replacing it, my truck ran perfect. I live in the desert which gets over 120 degrees and my truck runs fine now. Turns out the lower 1/3 of the old radiator was clogged, I took the plastic sides off and discovered crud clogging the lower 1/3.
