tip,
basic removal means,take the belts off,also apply summit to the switch,on the belt casing,else the dash light will stay on ,saying theres summit up with the system,

tip ,
if you leave the system on,and are happy to use it,periodically check this~

the load proportional valves(at rear on wishbone block)will need to be checked for,wait for it~small stones or gravel jammed in the seats of the lever arms,thus rendering that side not opperational in what its intended for,a small screwdriver will be needed to free any debris accumulated in that area.remember not to damage the seals on the load pins.

on two sets of these load valves ive had,both had (ironically in the same place and the same valve)small sticky gravel pieces,jammed in between the pin and lever arm,and when checked the arm wouldnt close enough to push the pin.

removal from the car is not necessary,though taking the rubber grommit out,off the wishbone location,will make this job operation easy!

hope this helps!

by the way,my car has the belts removed,but all the pipework still journeys through the valves,and im in the process of replacing the pipework,but still im going to plumb the same way,so if in future the car was to be standardised(the way the m.o.t. laws are going at present),the belts and switch need only be applied,.
