A couple of questions

[paulyboy]

On my S6 the fan cuts in at 96 degrees which i persume is correct. When you turn the ignition of does the fan suppose to stop as well?? i thought on most cars it carrys on running untill the temp drops?

where is the a/c fill point on the speed 6?

Cheers

The fans stop on the Cerbera when the engine is switched off - you've removed the source of the heat so the engine will cool down anyway.

If the a/c is similar to the 4.2 then find the a/c compressor and you will see the two hoses leading to the unit. There should be a valve with a plastic cap on each one - the larger valve is the filling point.
