# 1556389 Sealing Ring | Genuine Volvo Penta Part

## 🔧 Product Description

This genuine Volvo Penta sealing ring is a formed OEM sealing component used in the late-type engine sealing joint. It is manufactured to the original Volvo Penta dimensions and interface requirements so the mating joint retains its intended fluid, gas or contamination barrier. Late-type water-pump shaft sealing ring used in the D16/FH16-family coolant-pump assembly. In service, it seals the matched late-production joint against oil or coolant leakage. Fitment is controlled by the exact engine or product configuration and serialised parts list; confirm OEM number 1556389 against the installed assembly before ordering.

## 🚤 Compatibility

-   **Engine Family:** TWD, TID, TD, TAMD, TAD
-   **Serial Range:** up to serial 11848

## 🔌 Function

The sealing ring forms a leak-tight joint at a cooling system pipe connection, preventing coolant escape and air ingress at the mating faces. It compresses on assembly to maintain the seal under normal cooling circuit pressure and temperature cycling.

## ⚠️ Common Signs of Failure

-   Coolant seepage, drips or crusted residue around the pipe joint
-   Loss of coolant level with no other visible external leak
-   Hardened, flattened, cracked or perished ring on inspection
-   Persistent air in the cooling circuit or pressure loss during a system pressure test
-   Overheating or fluctuating engine temperature caused by gradual coolant loss

## 🛠️ Service Notes

-   Always fit a new sealing ring rather than reusing the old one — a ring that has been compressed once has taken a set and will not seal reliably a second time
-   Clean the groove or seat and check it for scoring, corrosion and old sealant before fitting; a mark across the sealing face will leak however good the ring is
-   Ease the ring into place without stretching, twisting or dragging it over sharp edges or threads, and check it is seated squarely all the way round before closing the joint
-   Do not add sealant or jointing compound unless the workshop manual for your engine calls for it, and tighten the joint or union to the figure given in that manual
-   Check the joint for weeping once the engine has been run up to temperature and allowed to cool, as many sealing rings only show a leak after a heat cycle
