Yes, you use R-134A. The low pressure intake valve is right in front of the engine, in the middle of the car (side-to-side) and about12" down on a silver metal pipe. Remove the cap, take your adapter (at the end of the hose) and pop it onto the intake valve. It will not fit onto the high pressure inlet valve (PLEASE DO NOT EVEN TRY!!!!) which is located on the driver's side down near the frame. Follow the directions on your kit for re-charging your system.
PLEASE let the manifold cool down before reaching into this space to access this valve!
On the 2003 Chevy Silverado 2500, the A/C system recharge capacity (R-134a) is: 1.6 lbs.
