Water Temperature Regulators (Thermostats) Have Been Redesigned {1355, 1380, 1393}
- Engine: Truck
- All
The new regulators (thermostats) have the same part numbers as the previous regulators, but the new regulators have a new change level. The new regulators are interchangeable with the previous regulators. Refer to Table 1 for the affected part numbers.
Note: Before using the new regulators, exhaust the old regulators. In engines with multiple regulators, use regulators of the same design.
