🛠️ Service Notes

• Check the engine serial number, as this cap covers the build from 1101052533 onwards
• One of the superseded numbers was listed as a housing rather than a cap - compare the part you have before ordering, as the coverage has been consolidated
• Renew the sealing ring or gasket and pressure-test the circuit after fitting
