The B max was due up for new discs and pads plus rear brake check & dust, so while the car was up on stands I took the opportunity to give the under-side a wax oil service. The main impediment to this is the plastic over-sills, which just half cover the blind grommets in the sills, so the first job was to remove them. With no Haynes or Ford manual available I needed to analyse how this area was assembled in the factory. As it happens they come off quite easily.
For each sill:
Firstly remove the push rivet at the front end of the sill, inside the bottom of the front wheel arch - don't be fooled by the Pozidrive recess - simply prize out the centre and pull out the rivet body.
In the rear wheel arch unscrew the two Pozidrive screws & washers holding on the plastic end plate, squeeze together the plastic spring clip and withdraw the plate[IMG]
Remove the six push rivets along the sill by prizing out the centres and withdrawing the rivet bodies.
The plastic over-sills will now just pull off. With both doors open start at the rear end and work forward[IMG]
Take the opportunity to thoroughly clean the sills, including the accumulation of dirt under the end plates. DO NOT use a screw driver or anything that will damage the paint - I found a combination of finger nails and a 1 1/2" paint brush to be ideal.
Once cleaned, remove the blind grommet blanking plugs from the sills.
Areas & sections to inject wax oil:-
Sills, via the six tooling holes now exposed[IMG]
Chassis box sections, whole length of car.
Front sub frame, NOTE - Areas to avoid: exhaust (fire risk), brake discs, rubber bushes.
Clean and set all push rivets & screws ready for re- insertion[IMG]
Refitting the over-sills is reverse of removal procedure.
