Seal the coolant joint and keep every drop where it belongs with the FEL-PRO water pump gasket 35552. Classified as a Water Pump Gasket but described by FEL-PRO as an Engine Coolant Thermostat Housing Gasket, this part is known by both names and is listed under each — it restores the coolant-tight seal at the housing-to-engine connection. It drops in as a direct-fit replacement for the listed applications, including the 2000-2009 Toyota Tundra, 2003-2009 Toyota 4RUNNER, 2001-2009 Toyota Sequoia and 1998-2007 Toyota Land Cruiser, plus a range of Lexus GS, LS, SC, GX470 and LX470 models — see the Buyer's Guide tab for the full list.
If a hardened, cracked or leaking gasket is the source of coolant seepage at this joint, the 35552 replaces it and re-establishes the seal during a housing or pump service.
