Stop coolant seepage at the outlet and keep your Cadillac's cooling system sealed with the FEL-PRO Engine Coolant Outlet Gasket 35863. It drops in as an application-specific replacement for the 2004-2009 Cadillac SRX (V8-4.6L), the 2005-2010 Cadillac STS (V8-4.6L) and 2006-2009 STS (V8-4.4L), and the 2004-2009 Cadillac XLR (V8-4.6L) and 2006-2009 XLR (V8-4.4L).
This gasket seals the coolant outlet flange to the engine, sealing the joint where coolant leaves the engine so it stays inside the cooling passages. Weeping, dripping, or a low-coolant condition around the outlet housing are signs the original gasket may need replacing.
Application-specific design: validated for fit, form, and function on the listed vehicles.
OE-level sealing: meets or exceeds all original equipment specifications.
Premium grade: designed with proprietary Fel-Pro materials for imperfect, real-world sealing surfaces.
Two mounting holes to locate the gasket at the outlet flange.
Country of origin: Taiwan.
