Good To Know

Q: Will this temperature regulator work with the LRC option? A: The title includes LRC, which typically refers to a specific cooling system configuration. Confirm your machine has the LRC option before ordering.

Q: How does this regulator affect engine performance? A: By keeping coolant flow at the correct rate, the regulator helps the engine reach and hold its optimal temperature. That improves combustion efficiency and reduces wear.

Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
