New Water Temperature Regulator Improves Temperature Control{1355,1354}
Usage:
3408 And 3412 Industrial Engines
Description of Change: An improved water temperature regulator is used in 3408 and 3412 Industrial Engines. The regulator is in the expansion tank group.
The regulator has a specific maximum leakage rate. This prevents engine operation at too cool temperatures. The result is more efficient engine operation and longer service life.
Adaptable As: The new 1W5253 Water Temperature Regulator is a direct replacement for the 9S9160 Water Temperature Regulator. Two are necessary.
