# 21096421 Piston Cooling Jet | Genuine Volvo Penta Part

## 🔧 Product Description

Brand-new genuine Volvo Penta piston cooling jet for TAD13/D13 lubricating systems. The calibrated nozzle receives pressurised oil from the main gallery and directs a controlled stream onto the underside of the piston crown, removing combustion heat and lubricating the piston-pin area.

## 🚤 Compatibility

Typically suits:

-   Volvo Penta TAD1346GE

-   **Engine Family:** TAD

## ⚙️ Key Features

-   Calibrated piston-under-crown oil nozzle
-   Used in the TAD13/D13 lubricating-system gallery
-   Maintains piston temperature under sustained load
-   Precision outlet orientation must be checked during installation
-   One jet supplied; retaining screw and oil-gallery parts are separate
-   Engine type: Volvo Penta 12.8-litre inline six-cylinder industrial diesel

## 🔌 Function

Sprays pressurised oil beneath the piston crown to control piston temperature and support piston-pin and cylinder lubrication.

## ⚠️ Common Signs of Failure

-   Piston scuffing or crown overheating
-   Blocked jet from sludge or metal debris
-   Low oil pressure from a cracked or loose nozzle
-   Jet bent away from the piston target area
-   Cylinder damage or seizure under sustained load

## 🛠️ Service Notes

-   Check the nozzle bore and the oil feed passage in the block are clear before fitting — gasket residue, sealant and carbon block these jets and a blocked jet lets piston temperature run away
-   Handle the jet carefully and do not bend, straighten or reshape the nozzle tube to make it fit; a bent or cracked nozzle sprays in the wrong place and must be replaced, not corrected
-   Fit the jet square on its locating dowel or spigot so it sits in the position the workshop manual for your engine shows, and tighten to the figure given there
-   With the jet in place, bar the engine over by hand and check the nozzle clears the piston skirt and connecting rod through the full stroke
-   Renew jets whenever pistons or liners are disturbed and the engine has run dirty or with extended oil changes, and confirm oil is delivered at each jet before the engine is loaded
