Cummins TSB 100657 New Thermostat – ISC and ISL Engines
« on: September 24, 2019, 07:02:24 AM »
This Cummins announcement dated April 2, 2008 announces the introduction of a reintroduced Caltherm thermostat and supersedes the old Standard Thompson thermostat. This announcement effects ISC and ISL CM2150 engines as they have a higher coolant flow requirement due to the addition of ERG coding and only this thermostat Part Number 4936026 can be used as a replacement thermostat in ISC and ISL CM2150 engines.

See the attached Cummins TSBs for details.
