Hey guy's I am looking at buying a 2005 2500 duramax sold my 1994 as an excuse to do so what issues and or problems to look for or be aware of any insight won your behalf would be greatly appreciated TIA

 

Overheating and head gasket issues on the lly, other than that just check the usual fluids, smoke, noises. They are good trucks, hope you like it!

How many miles? im in the same boat. A lbz,kodiak mouthpiece or afe makes one will solve the over heating. Make sure the upper radiator hose isn't collapsed thats one of the sighns of bad head gaskets! Good luck

 

The upper rad hose on my LBZ stayed hard as rock overnight when my gaskets went, it was due to excess pressure buildup in my cooling system, and it would cause coolant to blow over the overflow tank

a healthy upper rad hose is easy to squeeze and stays round
