## ⚙️ Key Features

-   Used between cooler core and end tank
-   Commonly two required per cooler
-   Resistant to boost pressure, coolant and heat
-   Direct replacement where part number 21244928 is specified
-   Engine type: D13 or D16 turbocharged marine diesel

## 🔌 Function

Seals boost air and cooling-medium passages at the charge-air cooler end tanks.

## ⚠️ Common Signs of Failure

-   Boost leakage or hissing
-   Oil mist around the cooler joint
-   Flattened, cracked or extruded sealing ring

## 🛠️ 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
