EricInAZ Posted September 10, 2021 Share Posted September 10, 2021 Put more highway miles into the Italian tune up today. Temp gauge was planted just below 1/2 way, until ... I got into stop & go surface street driving, then parked at a fast food joint. Temp went up to the Max - top of the gauge. Seems that the radiator fan runs only when the ignition is on. is this normal for a Civic? My other vehicles' fans run when I park & walk away with the ignition off & key in my pocket.

EricInAZ Posted September 11, 2021 Author Share Posted September 11, 2021 Radiator was about 2 quarts low, and a refill solved the overheating problem. Temp is stable, so I guess it's not necessary for the fan to run to cooldown after ignition is off. Link to comment Share on other sites More sharing options...
