    ABY sensors

    While I've got the rads out of the bay and plastics with easy access to the engine sensors etc would it be prudent to replace them and maybe the thermostat with new while I'm at it ? Are they prone to playing up ? Think they worked anyway but haven't run the car for any length of time etc on the roads... Or should I leave alone !? Just a thought ...

    The four things I'd replace whilst they are exposed are:

    1. Thermostat and o ring
    2. The 2 bar oil pressure switch, that's the one on it's own, not the one that's part of the oil pressure sender.
    3. The rubber hose attached to the back of the thermostat housing that links to the heater return steel pipe.
    4. The small rubber hose leading from the inlet manifold to the tube that feeds coolant to the turbo.
