## ⚙️ Key Features

-   4.3L GM V6 marine circulation pump
-   No-bypass configuration
-   Two-bolt pump layout
-   Brass impeller

## 🔌 Function

The pump circulates coolant through the engine so combustion heat can be transferred to the raw-water or heat-exchanger circuit.

## ⚠️ Common Signs of Failure

-   Coolant leaking from the pump weep hole
-   Bearing rumble or grinding
-   Reduced coolant circulation
-   Corroded or damaged impeller
-   Pump shaft seizing

## 🛠️ Service Notes

-   Establish why the old pump failed before the new one goes on — debris, a blocked strainer, a starved supply or a dry run will take out the replacement just as quickly
-   Fit new gaskets, O-rings and seals on the pump's joint faces and drive, with the faces clean, and use only the sealant the workshop manual for your engine specifies
-   Check the drive and the shaft it runs on — coupling, gear, key, belt or drive dog — while access is good, and renew anything doubtful
-   Prime or fill the pump as the manual for your engine directs, bleed the system afterwards, and confirm it is actually delivering before the boat leaves
-   Tighten mounting and cover fasteners evenly to the manual's figures; pump housings distort easily, and a distorted housing either leaks or binds
