Stop Overheating and Breakdowns – Restore Factory Cooling Performance
This upper radiator hose is engineered as a direct replacement for Parts 23275466/23278115, designed specifically for Volvo VNL/VN trucks (2007-2017) and Mack Anthem/ProStar trucks (2015-2020). It replicates the factory hose's exact 1.25" inner diameter, 300°F temperature rating, and routing to maintain unimpeded coolant flow – eliminating leaks that cause engine overheating, sudden power loss, and $500+ repair bills.

Why This Hose Beats Generic "Universal" Kits
100% Factory Match
3D-scanned from genuine Part 23275466 to ensure identical diameter (1.25") and routing – no leaks from misalignment.
Unlike universal kits that require cutting, this installs perfectly with factory clamps.
Truck-Grade Durability
Reinforced EPDM rubber withstands 300°F engine heat and coolant chemicals (tested in 500+ hours of real-world use).
Stainless steel clamps resist rust and vibration – no more "hose slippage" during long-haul trips.
10-Minute Fleet Repair
Includes pre-installed OEM clamps – simply unclamp old hose, install new one.
Pro Tip: Cool engine completely before replacement to avoid burns.
Critical Safety & Installation Notes
⚠️ ALWAYS ALLOW ENGINE TO COOL – Hot coolant causes severe burns (190°F+).
⚠️ Disconnect battery before starting to prevent electrical shorts.
⚠️ Do not overtighten clamps (15-20 ft-lbs max) – crushes hose and causes leaks.
⚠️ After installation, check for leaks at idle – if coolant drips, verify clamp tightness.
