Dorman - HELP Engine Coolant Reservoir Cap P/N:54016
Cracked, missing, or worn-out coolant cap? Seal your coolant recovery tank again with the Dorman - HELP Engine Coolant Reservoir Cap 82597, a direct-fit replacement reverse-engineered from the original cap. It drops in on many vehicles, including the 2000-2009 Chevrolet Silverado 1500 and 2005-2017 Chevrolet Equinox — see the "Vehicles it fits" section for the full list.
This cap closes off the coolant recovery/overflow reservoir, helping keep the cooling system's expansion tank sealed and contaminants out. If your original cap is cracked or lost, this reproduces its fit.
