    • Barometric pressure: 20.5 in. Hg (69.7 kPa) or more.
    • Engine coolant temperature: 14°F=X°F (-10°C=X°C). X = engine coolant temperature upper limit is determined by barometric pressure as indicated in graph. See Fig 1.
    • Fuel tank level: 1.3-3.75 volts.
    • Intake air temperature: 14-140°F (-10-60°C).
  2. Ensure all accessory loads (A/C, headlights, blower fan, rear window defroster) are off. Start engine and race at 3500 RPM for 200 seconds to warm up to normal operating temperature, then let idle for 120 seconds. See Fig 2.
