📋 Kit Contents

• 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
