Help keep coolant sealed where the coolant outlet / thermostat housing meets the engine block with the FEL-PRO Multi-Purpose O-Ring 35533, also listed as an Engine Coolant Outlet O-Ring and an Engine Coolant Thermostat Housing O-Ring. It fits many vehicles, among them the 2002-2006 Nissan Altima, 2002-2006 Nissan Sentra and 2005-2006 Nissan X-Trail, as a direct-fit replacement for the listed applications. See the Buyer's Guide tab for the full vehicle and engine list.
This O-ring seals the coolant outlet / thermostat housing joint to the engine block, helping keep coolant contained at that connection. Fel-Pro designs its gaskets for the repair environment, where sealing surfaces are often less than perfect. It builds them with proprietary materials so they are intended to seal reliably even on troublesome applications.
Signs this O-ring may need replacing include coolant seeping or crusting at the thermostat housing, or a coolant level that keeps dropping. Diagnose the source of the leak before replacing parts. If a failed O-ring is the cause, this part replaces it.
