Video tutorial

In this video tutorial, you can see how to replace the diesel filter in a Subaru Impreza: the first step is to lift the bonnet, secure it with the prop rod, and disconnect the negative battery cable and the two connector cables on the right. Using a 12 mm socket, undo the two bolts that connect the pump to the bracket.

Remember to disconnect the two connectors from the bracket before removing the pump assembly. Protect the engine with a cloth; to unscrew the diesel filter, you can use a special oil filter wrench.

Once the filter is empty, it can be unscrewed from the pump; next, remove the plastic cover from the new filter and lubricate the new O-rings with clean engine oil. The next step is to reassemble everything, so screw the new filter onto the lift pump (tighten by hand, not with the wrench).

Final step: operate the lift pump to fill the new filter, (starting the engine with an empty filter could damage the high-pressure pump of the injectors).

How to Reset the Tyre Pressure Warning Light on a Kia Rio?

The tyre pressure warning light displayed on the instrument cluster of the Kia Rio can be reset by inflating the tyres until they reach the recommended pressure value: this value is indicated on the sticker affixed to the driver's door pillar. Once all tyres have been inflated to the recommended pressure, turn on the ignition to check that the light has disappeared: if it is still present, it may be necessary to drive for a few miles, allowing the sensors to work and thus turning off the light.
