| -2- effect to the coolant, and eliminating subsequent trouble. Experiments are to be carried out on these lines. With regard to No-co-ro{C. C. Rose - Export Manager} corrosion inhibitor, this was apparently used by Vauxhalls as a standard filling on new cars, and appears to give satisfactory results if applied before serious corrosion has set in. Several chassis which have come into the Repair Department have been supplied with this, but as they have not come in since, no further data is as yet available. It appears that working on the information available to date the best move for cars which are in trouble would be to clean out the radiator as much as possible, ensure a good steam valve, blowing off at about 3 lbs/sq.in., and filling up with No-co-ro.{C. C. Rose - Export Manager} In the event of the expense being considered justifiable, the hot spot bosses could be changed to aluminium. (2) Car Heaters. Tools for producing car heaters were expected to arrive to-day and production anticipated to begin very soon. Two heaters are being made, one for R.R. without defrosters and one for Smith's with defroster. The principle being to cover up the heater exits when desiring to defrost and blowing all the air up to the screen. A small central knob was being provided for the shutter control. (3) B.V. Radiator. A B.V. radiator was taken back to Marstons for modification. It is proposed to omit the straps around the matrix, holding this in the yoke by bending the side strips in the form of an angle, and bolting on in the usual manner. This is similar to the construction on the Corniche. Weight and cost saving are not yet available, but will be forwarded as soon as they come to hand. (4) Wraith 30 Yoke. An accurate cost for the stiffened W.30 yoke was not available, but we were informed that it would only be in the region of sixpence. In view of this we consider the modification worth retaining as a safeguard. (5) Pressure Cooled Radiator. Schemes and details for the pressure cooled radiator | ||
