Anyone know where to find a low coolant level sensor. Isx15. 3 pin. I got the number off of the sensor, but when I look it up, it reads, not enough numbers. I ordered a couple off of the internet that look like mine, but they didn’t work. 361111 was the number on my sensor. Ty

Got a Cummins dealer near you? Its a pretty specific sensor. Not expensive but specific enough that generics don't usually work.

I do and I called them this morning, they said that Newell put this sensor on the coach.  I'm just going to order from Newell, to the tune of $649.00

Do you have the old one out? Perhaps try to take it to a fleet pride or kenworth Peterbilt shop and see what they say. 650 seems outlandishly expensive. Might end up being a common part for some other transport vehicle.

Only thing I could see was the name Casco, 120402 which is probably a mold number and a tag Made In somewhere I couldn't make out. The hex nut had something but no part number.

Not trying to be an AI idiot, but putting that number in a search engine says it is a coolant temp sensor. That could be hooey.

Have you put a picture of the sensor into Google Lens along with the number to see what results?

Grok says to clean the probe with mineral spirits.
