Can someone tell me how to install a coolant level sensor? I checked FAQ and saw nothing for the 240. Also, basic electrical knowledge appears to be critical to keep my car running well. I don't understand the posts on this site that deal with electric at all. I don't even know what an ohm is, other than I think I heard it on a Paul Simon record once. Where do I go for the minimal knowledge I need to keep up with the posts on this site that deal with electric?



Thanks,

At least some basic electrical theory, or the laws that govern electronics, is explained here - Collin Cunningham from Make magazine explains Ohm's Law.

Good luck.

If I were you, I'd go to a local community college where they teach basic electricity. You need to know volts, amps, ohms, how they are measured, and how they relate to each other. A lot of students thought very little of basic algebra and physics in school. But, when they get older and see how much a professional mechanic costs, they suddenly have an interest in basic physics.

That's a good suggestion worth looking into. I wish I would've paid more attention to math and science in school.
Thanks

Here is a link that I saved concerning the installment of a low coolant sensor:

Post back with questions you might have. I personally think the low coolant sensor is one of the most important upgrades you can add to a brick. All six of the Volvos I maintain for the family are equipped with one.

I too think of myself as being electrically challenged. I have learned a lot about electrons and their flow by simply reading posts and replys right here on the Brickboard. A willingness to learn goes a long way in acquiring an education.

Thanks to you and oleseahorse. i remember this post and lost it. I will gather the goods and give it a go.

Thanks again.

Hi Randy,

My last couple of assemblies used these vs the more expensive (but probably identical) McMaster Carr liquid level float switches.

They come from China in about a week. Amazing

These assemblies are now in four 240's and I'm still waiting for the day when they save my engine. I suppose the day is coming.
