SERVICING INFORMATION
HOOD LOCK: To open the hood, place the fingers between the radiator grille and the header bar, slightly right of the center,
and pull the rod firmly, releasing the hood. Place the fingers between the top of the header bar and bottom flange of the
hood at the center; pull forward as far as possible on the safety latch and raise the hood. The hinge design makes it
advantageous to pull forward as well as upward for easy raising of the hood. When closing the hood, push downward firmly
until the latch is fully engaged and the hood cannot be raised even slightly. If not properly locked, the hood will remain
partly open, held only by the safety latch,
BATTERY LOCATION: Under hood, left side. Size - 12 volts, 70 ampere hours, 66 plates. Negative terminal grounded.
RADIATOR CAP: Pressure cooling is employed with valve in cap set at 13 pounds. Never check the level until the engine
has been stopped for several minutes. Before removing cap, turn it until a slight stop is reached to allow any pressure in the
radiator to be relieved through the overflow pipe. Check coolant level when engine is cold and add water until it reaches line
marked "Filling Level-Cold" stamped approximately 1-1/4 inches below top of radiator tank.
RADIATOR DRAIN: Drain cock located at lower right corner of radiator tank front face. For complete draining, disconnect
heater and defroster hose. Dynaflow oil cooler is in lower radiator tank. Hoses between Dynaflow and radiator carry oil, which
may be hot. CAUTION - Do not remove the hoses when draining the cooling system. When refilling cooling system after
draining, the "Heat Control" lever below radio grille must be pushed to left of high position.
BLOCK DRAIN: Drain cock on each side of block.
GAS TANK FILLER: Center of bumper. Every 5000 miles disconnect fuel line at front of gas tank, remove strainer at tank
outlet and drain the tank. Clean or, if necessary, replace the strainer. When assembling the strainer, apply not more than 7 to
10 Ib ft torque to the nut.
JACKING CAR: The front and rear bumper must NOT be used for jacking purposes. Also, it is important that frame contact
lifts be equipped with adapters to compensate for the 10" wider frame used in 1957 and to eliminate possible damage to the
exhaust system. When using conventional twin posf lifts, care must be exercised not to lift against the rear axle housing
radius rod bracket. On some lifts it may be necessary to locate the car slightly off center to ins ure adequate clearance at
this point.
WINDSHIE LD WIPER: The windshield wiper blades must not be rotated by hand for any reason as this places a strain on the
cable fastenings.
As in previous years, when changes in design are made in the manufacturers'
later production, additional Mobilubrication Bulletin will be issued.
