## 📋 Kit Contents

-   Complete cylinder-head sealing component set - part number 20805523 - quantity 1
-   Internal seals are serviced only under kit number 20805523; Volvo does not publish separate service numbers for the contained pieces

## 🔌 Function

The kit restores the designated cylinder-head seal so oil, coolant, intake air or combustion gases remain separated at the serviced joint.

## ⚠️ Common Signs of Failure

-   Oil or coolant seepage at the serviced head location
-   Seal hardened or damaged during dismantling
-   Loss of sealing after reusing the old component
-   Contamination or corrosion in the seal groove
-   Repeated leakage caused by an incorrectly seated seal

## 🛠️ Service Notes

-   Fit every item in the kit at the same time; the kit is made up for one job and reusing an old seal alongside new ones is where leaks come back from
-   Clean and dry the sealing faces and grooves completely, taking off old gasket and sealant without scoring the metal
-   Inspect the shaft or bore each seal has to run on — a scored or corroded running surface will cut a new seal straight away
-   Lightly lubricate O-rings and lip seals with clean fluid of the type the system carries, and fit lip seals square with the lip facing the same way as the original
-   Assemble and tighten in the order and to the figures in the workshop manual for your engine, then pressure-test or run up and check for weeps
