How to Remove the Oil Filter Housing on a W123
The oil filter housing unit in the W123 acts as a housing unit for an oil filter to ensure dust and debris does not enter into other parts of the engine system. Periodic removal and replacement of this part is recommended to ensure safe and efficient driving.
Items Needed
- W123 Oil filter
- Oil drip pan
- Grommets
- W123 Housing unit
- Wrenches of various sizes
- Remove current oil. Understand the engine releases tiny particles of metal, dust and debris while the car is running, the oil pumps through the oil filter housed in the oil housing unit to prevent engine damage by dirty oil build up. To minimize damage to your engine and oil housing unit first remove all the oil in the housing unit by opening the bottom grommet area and allowing the oil to drain to an oil pan. This will insure oil will not leek or burst onto you or the engine as you remove the oil filter housing unit.
- Remove all the connectors from the tubes surrounding the housing unit of the W123. If you have drained the oil properly then the removal of these tubes will not cause damage to your engine or self by splattering oil. Test the amount of oil in your drip pan, if an entire oil change remains in the pan then you should have no problems removing the oil gaskets around the housing unit. If there is only a slight amount of oil, you may recheck your drain applications, and try a better drain system or visit an auto mechanic, as this may signal a greater problem with your cars cooling system.
- Proceed to remove the actual housing unit of the W123 oil filter, after all the oil gaskets and tubing are removed safely. There will be a slight amount of oil build up along the wall of the actual filter, and lower oil storage area below the filter. Seeing large amounts of oil in the actual housing unit may signal additional complications in your housing unit, check accordingly.
