Is your Freightliner giving you a false low coolant light?
Might be time to swap out the sensor.
This is a brand new coolant fluid level sensor from FUSCH AUTO.

It's a direct replacement for a bunch of Freightliner trucks, including the FL70, FLD112, FLD120, and M2 series.

The main part number is 3612521, but it also replaces 4903489 and cross references to NSN 6680-01-530-1204.

It's a 4-pin sensor, made of plastic and metal, in black and gold colors.

It screws right in.
If you're tired of that annoying warning light, grab this sensor and get back to hauling with confidence.

It's a direct fit, so no messing around.
