If you find that this radiator does reduce the jelleying the reason is probably in the method of mounting. The R.R. radiator is rigidly fixed to the frame and has one stay to the dashboard. Its inertia is therefore added to that of the frame. The Gallay radiator is attached to the body at the bottom and sides and has two stays to the dashboard. It is therefore "centrally mounted", its inertia is independent of the frame, and in addition it has to work as a body stiffener. Proof of this is that the brackets holding the two stays to the top tank of the radiator are already tearing away the material of the tank with the result that leaks occur at both these points. We suggest that you should try mounting the R.R. radiator on the body at the bottom, fitting two diagonal stays to the dash instead of one but not attaching it to the body at the sides. It will thus be centrally mounted but will not have to work as a body stiffener. Rm{William Robotham - Chief Engineer}/FJH.{Fred J. Hardy - Chief Dev. Engineer} | ||
