Subaru cannot get the temperature gauge to move during test drives and their tests indicate it is running within normal range – so they don’t know what to change/fix.
It happens to me when
- temperature is below 40 degrees.
- it happens within 10-20 minutes of driving … regardless of speed.
- it happens every day when it’s below 40 degrees – but just since the water pump and thermostat were changed and then the new faulty thermostat was then replaced …
- the gauge comes immediately down when I turn the heat and fan on
- I try to get it to Subaru when it’s happening, but I’m usually about 25-50 miles away and can’t get it to them when it’s happening
- it NEVER happens if the weather is above 50 degrees.
