Expansion tank, antifreeze and airbag sensor are OK to order and fit. I believe you went ahead and fitted the expansion tank already (this is my 4th one now!!). I believe I might have a pipe-outlet from my old engine sitting in Pattaya, will check.
I would like to personally check the hand-brake system, as from what I've seen on the forums it's very rare to require a complete replacement of the hand-brake system. Often times a re-calibration and check of brake pads is what is needed. So do NOT order this part yet.
What time is the car ready for collection today?
