Forklift Radiator Water Tank Cover — Kingstream Brand, 100% Professionally Tested
This radiator water tank cover (pressure cap) seals the radiator filler neck and maintains the cooling system’s rated pressure — typically 0.9 bar (13 PSI) on most forklift cooling systems. The pressure cap raises the coolant’s boiling point by approximately 3°C for every 1 PSI above atmospheric pressure, preventing coolant boil-over during heavy-load operation when engine temperatures peak. A failed cap that doesn’t hold pressure allows the coolant to boil at 100°C instead of the system’s designed 110-115°C, causing overheating even when the radiator, water pump, and thermostat are all functioning correctly.
This Kingstream cover is 100% professionally tested and ships in a carton box with 7-15 day delivery from Liaoning, China. Video outgoing inspection and machinery test report provided. The cap’s spring-loaded valve must seal against the radiator neck seat to maintain pressure — always inspect the radiator neck for corrosion or pitting before installing a new cap, as a damaged neck will prevent even a new cap from sealing.
Compatible with standard forklift radiator filler necks. Browse our forklift radiator cover selection for specific models and pressure ratings.
