## 🔌 Function

Passes engine coolant across raw water cooled tubes so heat leaves the engine circuit without the two water flows ever mixing.

## ⚠️ Common Signs of Failure

-   Running temperature climbing, especially at higher loads
-   Coolant appearing in the raw water side, or raw water in the coolant
-   Coolant loss with no external leak
-   Tube stack furred with scale or blocked with weed and debris
-   Corrosion or weeping at the end covers

## 🛠️ Service Notes

-   Renew the end cover seals and check the anode in the exchanger when fitting
-   Clean the raw water side and cure whatever caused the blockage, or the new exchanger will foul just as quickly
-   At nearly 48 kg this is a heavy item needing two people or mechanical lifting
