HEATER OUTPUT TEMPERATURE CHECK
Note. Perform this check if sent here from chart.
- Remove radiator cap when engine is sufficiently cool. Select heater (floor) mode, high temperature setting and high blower speed. Idle engine until coolant can be seen flowing in radiator. Install radiator cap.
- When engine is warm, after about 20 minutes, drive vehicle at 30 MPH (48 km/h). Measure ambient air temperature and floor outlet air temperature using accurate thermometers. If floor outlet air temperature exceeds minimum specification, heater output temperature is considered sufficient. See HEATER OUTPUT MINIMUM TEMPERATURE SPECIFICATIONS table.
| Ambient Air Temp. °F (°C | Floor Outlet Air Temp.°F (°C) |
|---|---|
| 0 (-18) | 130 (54) |
| 25 (-4) | 139 (59) |
| 50 (10) | 147 (64) |
| 75 (24) | 155 (68) |
