Dorman 924-5516XD coolant level sensor for the 2008-2019 Mack MRU 6-cylinder 10.8L, the 2009 MRU 6-cylinder 12.8L, the 2011-2019 MRU 6-cylinder 8.9L, the 2012-2018 MRU 6-cylinder 12.8L and other vehicles senses the coolant level with a magnetic float. This Dorman OE FIX engine coolant level sensor replaces a factory design whose float rides on a plastic shaft that is vulnerable to engine vibration in stop-and-go use.
- Magnetic float with a much larger sweep area to sense the actual coolant level
- Stainless steel shaft potted with epoxy to prevent failures from coolant ingress
- Real-time coolant information for drivers and fleet managers to schedule coolant service intervals
- Part of the Dorman HD Solutions line
Quick facts
- Part: Dorman 924-5516XD coolant level sensor
- Also called: engine coolant level sensor
- Fits: the 2008-2019 Mack MRU 6-cylinder 10.8L, the 2009 MRU 6-cylinder 12.8L, the 2011-2019 MRU 6-cylinder 8.9L, the 2012-2018 MRU 6-cylinder 12.8L and other vehicles
- Material: Metal
- Condition: New
A failing coolant level sensor can give false coolant readings, set fault codes or send the engine into limp mode. Before you replace this sensor, rule out low coolant (checked with the engine cool) and a damaged connector or wiring, since either one can also trigger a coolant level fault; a shop can test the circuit.
Fits
It also fits the 2008-2016 Mack LEU 6-cylinder 10.8L and the 2011-2016 LEU 6-cylinder 8.9L. Every application takes a single sensor, and this listing is one.

Frequently Asked Questions
Does the Dorman 924-5516XD fit the 2012-2018 Mack MRU 6-cylinder 12.8L?
Yes. The Dorman 924-5516XD coolant level sensor fits the 2012-2018 Mack MRU 6-cylinder 12.8L, and that application takes one sensor.
Is there a coolant level sensor for the 2011-2016 Mack LEU 6-cylinder 8.9L?
Yes. Dorman 924-5516XD fits the 2011-2016 Mack LEU 6-cylinder 8.9L, and this listing is one sensor.
Does this coolant level sensor with the attached harness come with mounting hardware?
No. The box holds one coolant level sensor with a separate harness attached to the connector. Mounting hardware is not included.
What thread and connector does the 924-5516XD coolant level sensor have?
The thread is M26 x 2 with a 26 mm thread diameter, and the sensor threads into place. The connector is a female, straight pin type with two wires.
What is different about the shaft on this Dorman OE FIX sensor?
The shaft is stainless steel potted with epoxy instead of a plastic one, which is meant to prevent failures from coolant ingress. The magnetic float also has a larger sweep area.
