Water Loss from Radiator on Phantom. In view of a customer's (Mr. H.{Arthur M. Hanbury - Head Complaints} Hill) complaint of loss of water, we have tried out tests with a production chassis. The radiator was filled up to its maximum level and then run at high speed for a distance of 110 miles. Water was lost from the radiator, bringing the level in the top tank to 1.125" above the matrix tubes. With this level of water a further 120 and 130 miles were run, with no further loss of water. The height of the water when cold measured .625" above the matrix. This follows the tests in France. We have since tried out a scheme LEC.3819 to lessen the pump efficiency at high speed with less loss of water. The tests have been satisfactory. We have been able to prevent the loss of two quarts of water. The results of the tests were - height of water cold above the matrix, 1.875" and 2.875" when hot. It retained this level after 250 miles of high speed. It has in no way interfered with the cooling efficiency. We propose to carry out comparative flow tests on the bed: also fit it to 28-EX for the 10,000 mile test. Hs{Lord Ernest Hives - Chair}/G.W.Hancock. | ||
