Water Cap Sakey 1.1 old type
SKU: HB-K-001
The pressure cap on engine coolant systems lowers the boiling point of the coolant while providing a safety mechanism to bleed pressure from the coolant if the engine overheats. The factory expansion cap is rated at 1.1 kg / cm3 or 16 PSI. The cap should hold this pressure and then bleed the pressure above this point.
