ACDelco® 21696 - GM Original Equipment™ Engine Coolant Radiator

I received the radiator in a thin box with very little packaging with the exception of at the ends there was the expandable foam. The radiator looked like it was a piece of bacon bent and the fins smashed. Will upload a picture if requested but not ordering radiators again.

Excellently packaged for shipping....Perfect OEM replacement for my automatic Saturn Sky....

For this OEM radiator, its is a very good idea to replace the lower hose AT THE SAME TIME that you install the radiator. What I found was that after I installed the radiator and had everything hooked up and in place and filled with fluid, the original hose had a bad seal and had a leak at the connection. The set up on this OEM radiator uses a push on coupling with a wire spring that fits on the hose to keep it in place. There is an "O" ring in the hose that over time will shrink and you can't purchase the O ring separately as it is built into the hose. Its much easier to install the hose before installing the radiator. Best to install both parts at the same time to be sure you won't run into a problem after installation or maybe a short time after the installation. I installed the hose after finding the leak without taking the radiator out and just removing the coolant reservoir and it was difficult but not impossible. Took as much time to install the hose as it did to install the radiator. Now that both have been replaced, my truck is running great. One other tip. When you fill the radiator, don't pour the antifreeze directly into the radiator as it can cause air pockets. Better to fill it from the top radiator hose as much as you can. Get a funnel and disconnect the top hose and put the funnel into the hose. Remove the radiator cap. Pour the fluid in slowly and allow it to seep down into the hose. By doing this, you will be pushing the fluid down into the engine and allowing the air to escape from the top of the radiator. Once you can see that the hose won't accept anymore fluid, reattach it, then pour directly into the top of the radiator. My research showed that if you get air pockets in the cooling system, it can cause your vehicle to overheat or have intermittent temperature changes. Don't forget to top off the reservoir.

Radiator in my 2007 Chevy Express 3500 4.8 L box truck was leaking badly. I called around locally for an OEM radiator and was getting quotes of $400+. I searched the OEM part 89019353 number in google and saw this ACDelco radiator come up on the TRUCKiD.com website. I was ordering this on a Friday morning and needed the radiator by Monday morning. The representative who helped me in a chat gave was very nice and gave me a discount code and link to order online and told me it would arrive by Monday. I actually received it the next day (Saturday) around 2PM. It took me a few hours to install and it was a perfect replacement for the original radiator that was in the truck, no changing hoses or anything just a clean swap. I am very pleased with the service I got from TRUCKiD.com and the quick turnaround they gave at no additional charge. I think I may have been fortunate that I ordered this during the COVID19 pandemic and the shippers at UPS were working really fast and that TRUCKiD got the radiator out the same day I ordered it and that I may have not been too far (a few states away) from where it was being shipped from. The shipping price was inexpensive and this saved me easily $150 by not going to pick it up at a local dealership. Thanks TRUCKiD!
