PACCAR MX-13 EPA2017 Oil Thermostat and Filter Cap Replacement with Oil Survey
Release Date
2/14/2020
Revision
02/28/2020: Revised oil filter pleat inspection and added oil thermostat replacement instructions.
02/19/2020: The population for this campaign has been expanded and the chassis list has been updated. A special survey form link has been
added for cross-division repairs has been added to the Procedure section. An explanation of parts availability has been added to the Parts section.
Condition
PACCAR MX-13 EPA2017 engines may have a faulty Oil Bypass Valve located in the Oil Filter Cap assembly. The plastic retaining tabs could
break off and put the lubrication system into an unfiltered state. An improved oil thermostat is also available for this same population of vehicles
and will be installed at this time.
PACCAR is conducting an engine oil survey to study the effect of engine oil on engine longevity. While the customer is in the dealership for this
repair, complete the Oil Survey with input from the customer.
Chassis Affected
Specific chassis with EPA2017 MX-13 engines. See the chassis list.
