This radiator cooling hose, part number 22891468, is a critical component in the engine's cooling system for Volvo and Mack trucks, facilitating the circulation of coolant to dissipate heat. It is constructed from high-quality, heat-resistant rubber compounds to withstand engine temperatures and pressure fluctuations, unlike a brittle or swollen old hose. Operators may notice coolant leaks under the hood, a persistent sweet smell of ethylene glycol, or a rapid increase in engine temperature if this hose fails.
Always verify with serial number before ordering.

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 bulge or crack in the rubber, or a small coolant leak. If ignored, the hose can rupture under pressure, leading to a sudden and significant loss of coolant and rapid engine overheating. The consequence is severe engine damage due to excessive heat, potentially requiring a complete engine rebuild.
Ensure the hose clamps are positioned correctly over the original hose routing marks on the radiator and engine nipples to prevent leaks. Do not overtighten the clamps, as this can damage the hose or the connection nipple.
It is recommended to replace both the upper and lower radiator hoses simultaneously, along with the thermostat and coolant, to ensure the integrity of the entire cooling system.
