DIATOR repairs are particularly
troublesome to the average .haulier, because, -unless he has a spare to fit on his vehicle, the lorry has to be held up while the defective part is being made good.. Ven if a spare radiator or block be available, which is not often the case. With the small man, it take quite an appreciable time to dismantle one pert and fit the other. A further disadvantage • is that it is extremely difficult to repair a tubular radiator block, so that it will stand up for any considerable tittle to the excessive vibration associated with the work of heavy lorries,. although we. believe that there•are some repairing concerns which can make quite a goo job of such work.
Pierce-Arrow users will avoid these expensive troubles if they avail themselves of the advantages . of a' new radiator just introduced specially for machines of this make by Messrs. George Bright, of kill Lane, Hampstead, London, NAVA the concessionaires for Pierce-Arrow vehicles in this country. Thc block of this radiator is built up of removable sections, each section containing two stacks of tubes fitted with large rectangular fins, which give an adequate cooling area. The
unscrewing of two nuts enables a section to be removed should a leak occur in it and a new one to be replaced in about five minutes. When the section is slipped out of place special valves in the top and bottom tanks are closed, so that, if it be required, the lorry can be run with some of its radiator tubes missing—a convenient feature in the winter months when it is often desired to cut down the cooling surface to keep the engine at a higher temperature. Incidentally, the small section is obviously much easier and cheaper to repair than if a whole block be taken down, as, in order to secure good results, it is necessary to run all the solder off the top and bottom plates, which have to be well cleaned, and then' resolder the complete block. The tube sections in the new model, of which there are •17, are, of course, toupled to the header and bottom tanks, both of which are single castings and Integral, with the side angle-brackets, thereby making for greater rigidity and strength. . The price of this radiator, which is arranged. so as to allow an inch more space for the fan of the Pierce-Arrow engine than is afforded by the normal type, is f20 10s., spare tube sections being priced at 17s. each. The component has a good appearance and Should be widely used by the numerous owners of the make of vehicle' in question.
