Any vehicle you buy may have problems...find out why the owner is selling.
You can check the vehicle history at Carfax or call your local dealer and they can tell you the warranty history of the vehicle.
The 96-02 S/T trucks are very dependable and trouble free (I owned a 96 S truck until last year when I traded up to a C truck) and my wife owns a 01 Jimmy.

check your raiator , becuase of dex cool, that stuff can really fuck up the raidiator and it will cause u to overheat
