## 🔌 Function

The gear transfers rotational drive within the engine's cooling system, turning the coolant pump so circulation is maintained while the engine runs. Correct tooth engagement keeps pump speed and coolant flow matched to engine speed.

## ⚠️ Common Signs of Failure

-   Whining, growling or rattling noise from the pump drive area that changes with engine speed
-   Visibly worn, chipped or pitted gear teeth
-   Excessive backlash or play in the gear train
-   Loss of coolant circulation and rising engine temperature despite a serviceable pump
-   Metal particles or debris found in the oil or during inspection

## 🛠️ Service Notes

-   Inspect the mating gear as well as the one being renewed; a chipped or worn tooth on the partner will quickly ruin a new gear, so change them as a pair where the wear is shared
-   Check the shaft, bush or bearing the gear runs on for wear and scoring before assembly and renew anything that is not to size
-   Fit the gear square and press it home rather than driving it with hammer blows, which spread the bore and mark the teeth
-   Oil the teeth and bearing surfaces on assembly so the gear is not run up dry on first start
-   Where the workshop manual for your engine gives backlash, end float or timing settings for the gear, set and check them to those figures rather than by feel
