Did not know the 05's overheated.....had one, until a week or so ago. sold it......good truck, just do not need a crew cab dually anymore. If you want an overheating GM diesel, try out the pre 97 6.5diesels........had a 96, now that was one overheating SOB! Still wish I had the truck tho. Put dual t-stats, and the post 97 high flo waterpump, overheat issues went away!
I'll still take the one that fits my butt best.....ie the 96 over the 05, and now my 2000 is my main driver..........Besides, I like the 90's body style better than the new heavy duty ones.
