Pressure Holding Reinforced Radiator Cap Heavy Duty Coolant Reservoir SHACMAN Unit

Reinforced Radiator Expansion Tank Cap for SHACMAN Trucks

A cooling system under load cycles pressure constantly. A standard cap lets coolant escape past a tired seal; this reinforced version holds the set pressure and returns coolant to the circuit instead of losing it on the road shoulder. The difference shows up on long loaded climbs where the system works hardest.

Part Specifications

Load Duty Behaviour

• Pressure cycles repeat all day on loaded haul routes.
• Standard cap bodies distort slowly under that cycle.
• Reinforced body keeps the seal loaded evenly.
• Coolant recovery works instead of venting to atmosphere.
• Fewer roadside top ups and less risk of overheating.

Application

Suited to mining, quarry and construction fleets where trucks run loaded for most of the shift in hot, dusty conditions.
