Antifreeze Concentration Check Check the antifreeze concentration. Use a mixture of 50 percent water and 50 percent ethylene-glycol base antifreeze to protect the engine to -37°C [-34°F] year around. Antifreeze is essential in any climate. It broadens the operating temperature range by lowering the coolant freezing point and by raising its boiling point. The corrosion inhibitors also protects the cooling system components from corrosion and provides longer component life. 50 / 167 pages Venting 17 mm, 19 mm Warning:
The pressure of the fuel in the line is sufficient to penetrate the skin and cause serious bodily harm. Venting is accomplished by loosening one or more fittings at the injectors and cranking the engine to allow entrapped Re-Tighten Line Fittings Torque Value: 30 N*m 122 ft-Ib] Warnig: Do not bleed a hot engine as this could cause fuel to spill onto a hot exhaust manifold creating a danger of fire.
