Dive Bar Casanova Posted November 25, 2018 Share Posted November 25, 2018 2001 GMC 2500 HD 8.1 HD gas. Stock radiator lasted 15 years 160.000 miles. Then the integrated trans cooler leaked and the complete radiator was replaced with what’s known as the best out there. Can’t get the replacement radiators to last 6 months. Any solutions out there? Anyone make a decent radiator? Quote Link to comment Share on other sites More sharing options...
dunefreak Posted November 25, 2018 Share Posted November 25, 2018 Why not another GM radiator? Seems like it did a good job lasting that long. Not available? 1 Quote Link to comment Share on other sites More sharing options...

Dive Bar Casanova Posted November 27, 2018 Author Share Posted November 27, 2018 I’ll be surprised if GM still has one available. Ill check Later this week. Quote Link to comment Share on other sites More sharing options...
aseman Posted December 10, 2018 Share Posted December 10, 2018 I've had the same issue with aftermarket radiators on my truck. Make sure the rubber mounts on the top and bottom of the radiator are still good and soft (to absorb vibration). Even then, aftermarket radiators may only last that long. A full aluminum construction unit would be your strongest. However if you have to stick with stock replacement, KOYO does pretty well for trucks. 1 Quote Link to comment Share on other sites More sharing options...

The GM radiator was 3 times the cost but definitely more robust construction. Other owners I know got over 260K miles out of their 8.1's and Allison's so It's worth the investment. Of the many many people I know with Allisons only know of one that died at about 150.000 miles. A split race bearing separated. Rated towing 12.500 he's been towing way, way more than that the entire life of the truck. Chevy dealer in Laughlin service manager told me they've never seen a bad one. Lucky to find any GM over the counter parts anymore. Got the last flip up center console avail in the USA. Truck has a rare bench front seat,, and leather at that. We'll keep it another 100K and then it'll do river duty garaged then just launching and retrieving boats. Been the most amazing truck, it's been everywhere done brutal duty. Those new 2019 GMC 6.2 4x4 1500's sure look nice. Edited December 13, 2018 by Dive Bar Casanova 1 Quote Link to comment Share on other sites More sharing options...
