20459065 O-Ring | Genuine Volvo Penta Part

🔧 Product Description

A genuine Volvo Penta o-ring used in the engine electrical and auxiliary mounting assembly. It is supplied as an individual service component under part number 20459065 and is intended to restore the original fit, alignment, sealing, support or operating function of the specified assembly. This listing supplies the named part only; adjoining components shown in an parts list for your engine are serviced separately unless explicitly stated.

⚙️ Key Features

• 0.005 kg
• For the engine electrical and auxiliary mounting assembly
• Serviced as an individual ring rather than in a set

🔌 Function

Seals a joint in the engine electrical and auxiliary mounting area, keeping oil, coolant or damp out of the interface where a unit is bolted to the engine.

⚠️ Common Signs of Failure

• Damp or oily film at the base of the mounted unit
• Corrosion creeping into the joint where moisture gets past the seal
• Fluid tracking down the block below the mounting face
• Ring found hardened, flattened or broken on removal

🛠️ Service Notes

• Always fit a new O-ring — never refit one that has been removed, as it has already taken a set in its groove
• Clean the groove and both sealing faces and check them for nicks, scoring and corrosion pitting; a damaged groove will leak however good the new seal is
• Smear the ring with a little clean lubricant compatible with the fluid it seals, then roll it into place by hand so it sits untwisted and fully in its groove
• Never lever an O-ring over a sharp edge or thread with a screwdriver; use a blunt plastic tool and protect any edge the ring has to pass
• Assemble the joint squarely and tighten to the figure and sequence given in the workshop manual for your engine — over-tightening extrudes the ring and causes the very leak you were curing
