CTA Tools 7124 Radiator Pressure Adapter Kit for 2017 and Newer GM L5P Duramax Diesel Engines

CTA Tools 7124 Radiator Pressure Adapter Kit for 2017 and Newer GM L5P Duramax Diesel Engines

• The CTA Tools 7124 Radiator Pressure Adapter Kit is designed for pressure testing the cooling system on 2017 and newer Chevrolet Silverado and GMC Sierra trucks equipped with the L5P Duramax diesel engine. These applications use two coolant tank caps with different thread directions: a vented right-hand thread cap on the side of the tank and a non-vented left-hand thread cap on the top. The kit includes both adapters and a center core with sealing O-rings to close the tank vent port and support accurate cooling system pressure testing.
• Features:
  • Designed specifically for GM L5P Duramax diesel cooling systems with two coolant tank caps.
  • Includes right-hand and left-hand thread adapters for the two tank openings.
  • Supports proper testing of the vented side cap and non-vented top cap arrangement.
  • Center core O-rings seal the tank vent port during pressure testing.
  • Helps prevent installation of the non-vented cap where the vented cap is required.
