FLV119 - 52mm x 2.5mm LH GM/GMC Radiator Pressure Adapter

• Designed for the L5P Diesel engine with two tank caps
• One cap is located on the side of the tank (Vented) with right-hand threads
• The other is located on the top of the tank (non-vented) with left-hand threads
• GM designed this to eliminate any chance of installing the non-vented cap where a vented cap is required
