With the engine sufficiently cool, perform the following steps:
- Remove the radiator cap.
- Start the engine.
- Let the engine idle.
Set the heater controls to the following:
- The HTR mode, the full RED temperature.
- The HIGH blower speed.
When the coolant flow in the radiator is visible through the filler neck, install the radiator cap.
Temperature Check
- Warm up the engine for about 20 minutes with the engine running.
- Drive the vehicle at 48 km/h (30 mph).
- Use an accurate thermometer in order to determine the temperature of the outside air and the temperature of the air discharged at the floor outlets.
The minimum acceptable heater output temperatures at 4 different outside temperatures are represented in the table.
Outside Air Temperature | Heater Air Temperature |
|---|---|
-18°C (0°F) | 54°C (130°F) |
-4°C (25°F) | 59°C (139°F) |
10°C (50°F) | 64°C (147°F) |
24°C (75°F) | 68°C (155°F) |
Minimum acceptable heater output temperatures for outside air temperatures other than those shown may be approximated by using the Fahrenheit scale and rounding off the outside air temperature to the nearest 5 degrees.
When the outside temperature is below 50 degrees, allow an additional 1.8 degrees of heater output temperature for every additional 5 degrees of outside temperature.
When the outside temperature is above 50 degrees, allow an additional 1.6 degrees of heater output temperature for every 5 degrees of outside temperature.
