Operation: Secondary air pump disassembly instructions

To cold start a petrol engine, a "rich" mixture is required, ie a mixture with excess fuel. Since the catalyst in this operating state has not yet reached its operating temperature, a considerable amount of carbon monoxide and hydrocarbons is formed in the time interval between cold start and the intervention of the lambda regulation. do not burn. By means of the insufflation of oxygen-rich ambient air into the exhaust manifold ("secondary air"), a post-oxidation ("afterburning") of the harmful substances takes place at that point. In the car model presented in the video, the secondary air pump is tested right in the front part of the engine and is fixed by an aluminum collar: then unscrew the fixing pins of the bracket, disconnect the socket and the hose to complete the disassembly.

Handbrake adjustment on Ford Ecosport

First remove the plastic profile at the base of the gear lever. To do this, slightly widen the side edges and carefully lift it to release it. There is no need to remove it completely, just move it forward to avoid bother. Now remove the plastic center console around the handbrake by first working from the rear to release it and lifting it until the brake lever passes. Also in this case it is not necessary to remove it completely but, paying attention to the connected cables, it can be stowed in front of the passenger seat. At this point we notice that at the base of the handbrake lever, on the front, we find a nut. By acting on it, with a 10 wrench, we can adjust the brake force, increasing it by turning the nut clockwise, or decreasing it by turning it counterclockwise. Once adjusted, the center console can be repositioned first, pressing lightly to engage it, and then the profile of the gearbox base.
