An ACDelco GM Original Equipment Radiator Cap is a spring loaded cap that seals the radiator filler neck or surge tank, and is a GM-recommended replacement for your vehicle’s original component. It maintains pressure on the cooling system while the engine is operating, which raises the boiling point of the engine coolant. It also replenishes the system with coolant from the expansion tank (if equipped) when the engine cools off. This original equipment radiator cap has been manufactured to fit your specific GM vehicle, providing the same performance, durability, and service life you expect from General Motors.

Bought this as it says it fits my van , also after reading good reviews . A mistake . I had to buy a special large pliers in order to close and open the cap. Should have bought a cap with ears.

My 1998 Chevy 1500K had a really scary looking garbage cap on it when I bought the truck used. No writing on it whatsoever. The water pump went out so I replaced the cap and all the hoses. Now with this cap I feel I have a cap I can trust. It's been 3 months and no problems. Fits very tight so it gives me confidence it won't leak. Time will tell.
