# 21986932 Cylinder Head | Genuine Volvo Penta Part

## 🔧 Product Description

Replacement cylinder-head assembly/casting for the Volvo Penta engine build that specifies 21986932. Combustion-chamber profile, injector bore, valve layout and coolant passages are product-controlled; supplied contents must be confirmed before ordering.

## ⚙️ Key Features

-   Precision-machined combustion chambers and deck face
-   Correct valve, injector and coolant-passage geometry
-   Designed for the matching block, gasket and fasteners
-   Pressure and flatness must be checked during installation
-   Assembly contents must be confirmed before ordering

## 🔌 Function

Seals the top of the cylinder block and houses the combustion chambers, valves, injector locations and coolant passages required for engine breathing and combustion.

## ⚠️ Common Signs of Failure

-   Coolant loss or combustion gas in the cooling system
-   Low compression or misfire
-   Cracks between valve seats or injector bores
-   Warped deck surface and head-gasket failure
-   Valve-seat, guide or cam-bearing damage

## 🛠️ Service Notes

-   Check the head for cracks and check the head and block faces for flatness with a straight edge before assembly, and have any doubt about the face or the valve seats resolved before the gasket goes on
-   Clean the gasket faces with care and without scoring them — do not attack an aluminium face with abrasive discs or scrapers, and keep debris out of the bores, coolant passages and bolt holes
-   Always use a new head gasket, and tighten in the stages, sequence and torque-plus-angle steps given in the workshop manual for your engine, with the threads and mating faces clean and lubricated exactly as that manual specifies
-   Head bolts on modern engines are angle-tightened and stretch permanently, so renew them wherever the manual calls for it rather than reusing them
-   Refill and bleed the cooling system properly, then run the engine and carry out any retightening or valve clearance recheck the manual requires after the first running period
