Replacement of Radiator was easier than I thought it would be.
Reviewed in the United States on February 19, 2023 by GABRIEL STOPKE
Only dislike with manufacturer was the drain valve was not tapped out. Threaded. Used the radiator anyway. Shipping not very good. Must have put it under a stack of tires. Came to my door with a bow in the middle of the core. Boxed was crushed. Used it anyway being a former mechanic thought I would try it anyway. It worked fine no leaks. They could have put a big sticker on the shipping box that said "do not bend or crush". Don't think it would have mattered in the times we live in. Manufactures workmanship good. Shipping people not good.

I would highly recommend this radiator. I installed it myself on my 2003 GMC Sierra 2500 HD 6.0 truck. It took my about 3 hours to do it myself and I saved a lot of money. I would suggest going on you tube and seeing some installation videos before taking this task on. You also want to make sure that your oil cooler connections are secure otherwise you'll make a mess and have your oil leak if the connections are not secure. I would highly recommend this radiator over the other higher priced aluminum radiators. It would also be a good idea to replace the top and bottom radiator hoses while you are it. It's the smart thing to do. I live in AZ and our summers here are brutal and our radiators take a beating here. You can't go wrong with this product and as always Amazon pulled through for me again.

Item came faster than ant part store could guarantee. The fit was perfect and I have piece of mind that it is an OEM part (for the same price as some knockoffs.)

Quick and easy install, everything went right in as it was supposed to. Shipped all the way to Alaska with 0 damage. Very impressed and would highly recommend. Make sure to double check the line clips before installing.

Lowest price that I could find when you included shipping. It’s the real GM part and exactly replaced the old one in my 2004 Escalade with the 6.0.

Part is new as advertised but when I got it it looks like the whole unit was bent/tweaked a little bit. Not sure if that's a product manufacturers issue or a packaging issue. Doesn't appear to affect the performance of the product but I will update this review if there is a problem with leakage. Thanks for reading fyi was delivered a day early!

Perfect direct Delco replacement for my 2004 GMC Yukon Denali. Careful removal and install netted me 4 hours of labor including cleaning of other parts etc. No leaks no problems and works as original did. I replaced mine as the EOC (engine oil cooler) O rings inside plastic tank had begun to seep leaving small drops of coolant on the garage floor. You can view some procedures on YouTube that are useful in observing the procedure.
