Rolls-Royce Phantom III -

	Side view of the later type radiator steam valve.
	Top view of the valve showing the spring-loaded outlet ball.
	Steam valve housing. The original bellows mechanism required this lid to be vented to the atmosphere whereas the later, ball valve type, needs a sealed lid. This picture shows the vent holes after the vents holes have been soldered up.
	After timing the ignition the radiator was temporarily installed. The water pipes were attached to the engine which was then filled with a weak solution of antifreeze and hot water - no leaks evident. The ignition was switched on and the fuel pumps primed the carburettor - no leaks evident. The starter button was press and after about one revolution the engine fired but did not start. The hand throttle was opened slightly and a second attempt produced the same result. With slightly more hand throttle applied the engine fired immediately and settled to a steady tick-over of about 800rpm with maximum oil pressure. There are three minor adjustments to be made before the bodywork is re-fitted:- 1) one banjo connection in the 'V' is leaking oil 2) one petrol pipe union is leaking 3) the clutch adjustment needs refining.

But it started first time!!!
