Keep your heavy-duty cooling system sealed and holding pressure with the Dorman - HD Solutions Engine Coolant Recovery Tank Cap (902-5502). This twist-on cap installs as a direct-fit replacement across a range of MACK trucks — including the 2004-2007 MACK CV, 2006-2007 MACK CXN, 2006-2007 MACK CXP, and the 2008 MACK CHU, CXU, GU7, GU8, LEU and MRU — spanning the 6-11.9L, L6-10.8L and L6-12.8L engines (see the Buyer's Guide tab for the full list).
The coolant recovery tank cap closes off the reservoir and holds system pressure so coolant stays contained as it heats and cools. If your original cap is cracked, warped, or lost and no longer sealing, this application-specific replacement is engineered to match the dimensions of the factory cap.
- Pressurized design: rated to a maximum of 10 PSI; non-vented, with no pressure release lever.
- Twist-on attachment: secures with a simple twist for quick, tool-free service.
- Metal construction measuring 58.42 mm in diameter.
- Application-specific fit: made to match the original cap on the listed years, makes and models — a quick, low-cost alternative to a dealer trip.
Country of origin: India. Package contents: 1 coolant tank cap.
