Oil Filter Heat Exchanger Gasket Replacement

Model: Mazda Cx7 MK 1 - Years 2006-2012
Part: Checks and maintenance

To replace the gasket of the oil filter heat exchanger, proceed as follows: drain the engine oil through the designated drain plug located under the oil sump, extract the oil filter cartridge, which is located right in front of the sump, by unscrewing the plug underneath. Disconnect the engine oil pressure bulb and unscrew the fastening bolts of the oil filter support, paying attention to the gasket between the support and the engine block. At this point, it is possible to separate the heat exchanger from the oil filter support and replace the internal gasket, aligning it with the respective centring tabs.

How to Replace the Rear Light and Bulbs on a Ford Focus Year 2000

To replace the rear light and bulbs on a Ford Focus 2000/2004, first, open the tailgate of the boot. This gives access to the screw that holds the rear light in place. The screw to undo (using an appropriate screwdriver) is located inside the light and corresponds to the fold that accommodates the tailgate (as shown in the images). Once you start to undo it, continue with the operation and then remove the nut from the inside of the bodywork. At this point, you can remove the light, being careful to disconnect the electrical supply by unplugging the connectors or removing the entire bulb holder from its housing. This way, you can replace the bulbs. To reassemble everything, simply follow the described operations in reverse order.
