my brother in law has an 1900 Aircooled on an A reg don't know engine codes. We re-tapped no 2 cylinder plug hole recenlty and in faffing about with the tinware whilst doing so severed a wire linkage that runs downwards at the crankshaft pulley/fan end of the engine. It operates some sort of an airflow control flap. Can anyone tell me waht this flap is and how critical to proper running its please. I'm not used to watercooled

hi m8
thats the thermostat wire i think from what you say,,, it runs from the bar above the tinware through a hole,, round a pulley and is connected to the thermostat. if its broken dont worry as the flaps are sprung so that in the event of this failing, the flaps open fully for full engine cooling. it will just take a little longer for the engine to reach full operating temperature in winter as when closed by the thermostat the flaps limit the ammount of cooling air flowing over the engine.
