Air Cleaner - Normally serviced every 5000 miles. If car is operating in dusty territory, however, check condition of air cleaner and clean it if dirty. See cleaning and filling instructions under "Every 5000 Miles."

Radiator - Check coolant level only when radiator is cold. Maintain level at line on tank marked, "filling Level - Cold," using water. Filling above level line or when radiator is hot will cause loss of coolant. CAUTION: Do not remove cap when radiator is hot because coolant will boil and overflow when pressure is released. When refilling cooling system after draining, "Heat Control" lever must be moved to high position. See Page 5.

NOTE: If cooling system is being drained for storage where freezing is likely to occur, it is necessary to disconnect heater and defroster hoses to thoroughly drain them. If car is Dynaflow equipped, disconnect lower hose at transmission oil cooler.

Manifold Valve Shaft - Place a few drops of graphited kerosene on shaft at each end and rotate shaft to work lubricant into bearings. If shaft is frozen, free up by tapping ends of shaft lightly with hammer.

Throttle Control Linkage - Place a few drops of engine oil at connections. Work Lubriplate into Equalizer Shaft bearings and wipe off surplus lubricant.

Generator - Place a few drops of engine oil in cups at both ends of generator. Avoid excessive oiling which may affect brushes and windings. Do not lubricate while generator is in operation.

Master Brake Cylinder - Thoroughly clean filler cap nut before removal to avoid getting dirt into reservoir. Add fluid as required to bring level to 1/2" to 1" below top of filler opening. Use G.M. or Delco Super No. 11 Hydraulic Brake Fluid. NEVER USER RECLAIMED FLUID OR ANY MINERAL OIL.

Tires - Inflate all tires to pressures given on page 14.

WARNING: It is not possible to inflate tires correctly when they are hot.

Hood Fastener Mechanism - Lightly coat latch lever and pilot with Lubriplate.

Door Locks and Strikers - On Series 40-60 apply G.M. Door-Ease Lubricant at the following points: (1) Top of bolt housing; (2) Gear teeth on striker. On Series 50-70 apply G.M. Door-Ease Lubricant on (1) Wedge plate on lock; (2) Wedge contact surface on striker. Use only S.A.E. 10 engine oil on lock bolt roller.
