Dorman - HELP Engine Coolant Reservoir Cap P/N:54370
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 a long list of GM applications, including the 2005-2017 Chevrolet Equinox, 2000-2009 Chevrolet Silverado 1500, 1999-2012 Chevrolet Malibu, 2002-2009 Cadillac Escalade, 2001-2009 GMC Yukon, 2003-2009 Hummer H2, and 2002-2010 Saturn Vue — see the Buyer's Guide tab for the full list of 76 applications.
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.
