Have a vortec Engine in my 2000 1500 gmc Sierra, how do i find out what type of 5.3 it is?
Replacing power steering cooler lines. Believe i have a vortec 5.3 but not sure if its a high
performance or regular engine
There is only one Vortec 5.3 in 2000 -- 2003 in the Sierra. 285HP http://www.pickuptrucks.com/html/sierra.html
There is in fact a 5.3 HO High Output but not in a Sierra. Like this (click for full screen)
