Full model list at the end of this description.

## ⚙️ Key Features

-   One top plate used per heat exchanger
-   Forms the upper structural closure of the plate pack
-   Accepts ten securing screws and washers
-   Works with spacer tubes 21111099 and 21111110
-   Plate only; cooling plates, gaskets and hardware are separate
-   Engine type: Volvo Penta D13 and D16 marine diesel

## 🔌 Function

Compresses and aligns the plate stack so coolant and raw-water passages remain sealed and structurally supported.

## ⚠️ Common Signs of Failure

-   Coolant or seawater leakage at the plate pack
-   Corrosion or pitting on the plate face
-   Distortion from uneven tightening
-   Cracked mounting area
-   Repeated gasket failure from poor plate flatness

## 🛠️ Service Notes

-   This is the top closure plate only — check the ten spacer tubes (21111099 / 21111110) and their securing screws and washers are serviceable before reassembly, since none of these are supplied with the plate
-   At close to 7.7kg, support the plate positively as the last screws come out, and inspect the sealing face for distortion or corrosion pitting before it goes back against a new gasket set
-   Draw the ten screws down evenly and in sequence rather than fully tightening any one first, so the plate compresses the stack squarely instead of cocking against it
