I just caught a mention of a coolant level sensor in Warren’s emails regarding his install. I enjoyed his pics and write up very much. When I get through my current failed head gasket situation I want to add a coolant level sensor. My expansion tank cracked on the freeway and I lost the gasket. I’ve since installed a new aluminum expansion tank but the damage was already done. What are you all doing for coolant level sensors? Where’d you get them? What parts did you buy? Where did you install them? How did you install them??I’m actually open to some kind of horn situation but want to hear what you’ve done.?

Back in my salt flats days we put a massive horn on our racers coolant level sensor so you could hear it over a 736 cubic inch diesel engine with a helmet on.?

The coolant expansion tank from RMW includes a coolant level sensor.

But they also sell just the replacement sensor for about $15

So wait, there was a factory coolant level sensor? How did it work? How did you know it went off? My Vanagon was converted in 2002 and I didn’t own it until?10 years after that so no surprise I didn’t know about this.?

Yes, there was a factory coolant level sensor that screwed into the top of the original 2.1 expansion tank. It had two prongs. When you started the 2.1 engine the temp light flashed a few times then, if there was coolant enough to touch the contacts, it went out.?

Where did you get your new aluminum expansion tank? ?Either it had a sensor mounted or a place for one.?
