Re: Loss of Water in Phantom II Radiators. Chassis No.88-MS - H.{Arthur M. Hanbury - Head Complaints} Hill Esq. Mr. H.{Arthur M. Hanbury - Head Complaints} Hill the Owner of 88-MS brought his car to Derby for us to deal with his further complaint of losing water. He arrived during the morning, having stayed overnight in Derby. He stated that he had lost over a quart of water on his run up from Weybridge (140 miles) measured when the engine was hot, and that the water was below the tubes when he started at the Hotel. The water was a little below level 'A' or approx. 1/2" above the tubes when measured outside the front office at W. We let the engine cool off but the water level was still above the radiator tubes although below the tunnel through which the calorstat control passes. To enable us to make comparative tests we filled the radiator to level B. (cold) and ran the car for 100 miles and lost nearly a quart of water. As suggested by you we carried out tests with the Bentley type steam escape pipes fitted to the radiator. In the meantime, whilst these pipes were being fitted to the radiator, we carried out the same test of 100 miles with a new production radiator and the loss of water was again nearly one quart. We got Mx.{John H Maddocks - Chief Proving Officer} to carry out a similar test on a new production chassis and we found the loss of water also to be about the same. We then carried out a 100 miles test with the Bentley type steam escape pipes fitted to Owner's own radiator, and we lost approximately one pint of water. A further 276 miles were run which included the return of the car to Weybridge and the total loss of water for the 376 miles was one quart. We should be pleased to know if you consider any further improvement is possible. The Owner himself appeared satisfied with the above result. Ha/WT. | ||
