This is a radiator cooling hose, specifically designed to circulate coolant within the engine's thermal management system for Volvo and Mack trucks. Manufactured to strict OEM specifications, it ensures robust performance and longevity, unlike a brittle or leaking old hose. Observable issues include coolant leaks around the hose connections, visible cracking or swelling of the rubber, or a persistent engine overheating warning.

Cross-reference part number with serial number before ordering to confirm fitment. Keep original parts until new ones are confirmed correct. Record part numbers replaced for future reference.
Always consult the OEM service manual for model-specific torque values and procedures. WhatsApp our technical team if you need fitment guidance.
The initial symptom of a failing radiator hose is often a visible coolant leak, especially at the connection points or along the hose body. If ignored, the hose can degrade further, leading to a burst under pressure, causing rapid coolant loss and severe engine overheating. A burst hose can also spray hot coolant, posing a burn hazard to personnel.
Ensure the hose clamps are positioned correctly over the original hose marks on the pipe to ensure a secure seal. Do not reuse old hose clamps, as they may not provide adequate pressure.
When replacing a radiator hose, inspect all other coolant hoses for signs of wear, and check the condition of the radiator and water pump.
