-   **HP Range:** 200-430 HP

Full model list at the end of this description.

## ⚙️ Key Features

-   Extensive exact V6 and V8 application list included below
-   Correct factory cross-section for the designated coolant-system joint
-   Material selected for hot coolant, pressure cycling and marine engine temperatures
-   Maintains system pressure while preventing coolant leakage and air entry
-   Typically shown as a multi-quantity service item within the heat-exchanger/expansion-tank assembly
-   Engine type: Freshwater-cooled electronically controlled petrol V6 and V8 marine engines

## 🔌 Function

Seals a coolant passage in the heat-exchanger/expansion-tank assembly so the closed cooling circuit can retain pressure without external leakage or air ingress.

## ⚠️ Common Signs of Failure

-   Coolant staining or dampness around the joint
-   Slow unexplained coolant loss
-   Cooling-system pressure decay after shutdown
-   Air entering the closed-cooling circuit
-   A flattened, cut, hardened or swollen seal found during service

## 🛠️ 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
