Thermometer Test Of Sensor

NOTE: Test must be made with engine cold and air cleaner temperature below 85°F.

Remove air cleaner cover and install a suitable temperature gauge as close as possible to sensor. Reinstall air cleaner cover (do not install wing nut). Start engine, air door should open immediately (if engine is cool enough). When air door starts to close, remove air cleaner cover and read temperature gauge. It must read 115°F ± 20°F. If air door does not start to close at temperature indicated, temperature sensor is defective and must be replaced.
