Faster Response Water Temperature Regulators; Service Simplified
Usage:
All Truck Engines Except 3208 Truck Engines
Description of Change: Water temperature regulators with a faster response are now used in many engine applications. See chart for part numbers of the former regulators. The new regulators listed will eventually be used in all applications of the former regulators.
The faster response regulator opens at a faster rate and closes faster. In some cases the opening temperature is raised 3 °C(5°F).
Adaptable To: The new regulators are direct replacements for any of the former regulators as listed. Only the four new regulators are used in production and can be used in parts service to replace the listed regulators. This makes parts service easier.
