Intake Manifold Gasket Set 3857662 807473A1 for Volvo Penta 5.0 5.7 Vortec 1997+ 2 PCS
Product Overview
Intake manifold gasket set for Volvo Penta and MerCruiser 5.0 L and 5.7 L Vortec engines from 1997 onward, supplied as 2 x intake manifold gaskets. It replaces Volvo Penta 3857662 and 287753, MerCruiser 807473A1, OMC 3856394, Sierra 18-0488, Mallory 9-61213 and GLM 30347. These gaskets seal the manifold to the heads; a failed set shows up as a coolant or vacuum leak at the manifold joint, a rough idle, or a lean fault code on one bank.
