Dorman - HD Solutions Engine Coolant Level Sensor P/N:924-5516XD

The original equipment coolant level sensor on certain Mack trucks often provides inaccurate data that sends the engine into limp mode, causing costly vehicle downtime. The false readings are due to a failure-prone factory design notorious for improperly determining coolant level. The OE design delivers readings sent from a magnetic float on a plastic shaft that is vulnerable to the engine compartment vibrations typical of stop-and-go use refuse trucks and other short-haul applications. Continuous jostling of the sensor assembly and limited float range can generate fault codes. This Dorman OE FIX solution more consistently and accurately monitors coolant levels. It features a magnetic float with a much larger sweep area to more accurately sense actual coolant fluid levels. A rigid stainless steel shaft potted with epoxy prevents failures from coolant ingress. Additionally, a separate harness attached to the connector allows for simplified installation by removing the need to index the OEM sensor. Installing this upgraded Dorman OE FIX solution helps drivers and fleet managers avoid unnecessary truck downtime and possible engine damage.

Coolant Level Sensor Replacement
