GM Genuine Parts 20837 🔧 Radiator: Reliable and Authentic Cooling Solution Review

Fits 1999 GMC Jimmy 2wd. There is no drain hole for a drain plug on the underside of the radiator, but you can always remove the hose to drain the water from the radiator.

What a disappointment! This AC Delco cooler doesn't have a drain plug, I should have gotten a cheaper option and I probably should have gotten a drain plug! But I mistakenly thought I was buying a genuine part!

Local Chevy dealer wanted $800+ and my Blazer for 5 days to replace a new radiator. It seemed like a daunting task, but I was kind of fearless and tired of driving around hoping Barrs StopLeak wouldn't let me down. This job took me about 3 hours this weekend mechanic. I also replaced the radiator hoses. The hardest part was installing the factory spring clamp on the lower hose to the cylinder block with pliers. I gave up after about 90 minutes of fumbling (I was pushy but it was late at night…

The drain cock is cast but does not work. I recently purchased this radiator to replace the one in my 2002 Chevy S10 (V6). This appears to be an exact replacement EXCEPT the drain line (faucet) is molded into the bottom of the passenger side but is not drilled so you cannot use the old faucet on the new radiator.
