Hi all, I have a 1995 Honda Acty Street. Just did a ton of maintenance and the van is running tip top. I noticed today, and it may be normal but at idle I can hear a vacuum pump or some kind of electric pump or solenoid clicking on every 12 seconds for 8 seconds. Its idling find running fine, doesn't change with ac on or off. Just want to know if this is normal ? I plan on digging into it further when I have time to pop the engine bay open and find the sound.
could it be the electric fan cooling the engine/radiator? That runs via temperature sensor/thermo switch
