We know that immediately the water boils, about a gallon of water is lost. It would be interesting to know whether at any time the car was run short of water.

Had the ignition actually given trouble before you did this or had you found the points pitted and corrected them in order to save trouble later on? As regards the front cross member - to replace this means unbuilding the whole car. It is necessary to remove the engine unit from the frame, to knock out the rivets fixing the pressed steel cross member under the radiator and to spring apart the side members in order to take it out or refit this front cross member. We have put it up to W.W. that we think it is too much of a job, but if it has to be done, we recommend that bolts are used for fixing the pressed steel member on one side also we need some modification to the front cross member as it has failed on both cars running the 10,000 miles. We think, in view of the trouble caused | ||
