1304010D8BD0 metal expansion tank cap is the pressure cover for JAC truck coolant expansion tank. It seals the expansion tank and maintains the rated pressure inside the cooling system. Raising the boiling point of coolant, it prevents the cooling liquid from boiling and overflowing under high working temperature. The built-in pressure valve and vacuum valve work automatically to balance internal pressure as temperature rises and falls.
After long service time, the sealing rubber ring will age, deform or crack. The pressure spring may also lose elasticity. A failed tank cap causes coolant leakage, water shortage, engine overheating, which may lead to engine cylinder head damage. It is a small but critical spare part for truck cooling system maintenance.
