I needed a replacement starter for my mower and wasn’t completely sure which one would fit. I sent them a message and they got back to me quickly, asked for my model information, and helped confirm the right part before I ordered. Everything was handled professionally and the communication was great. Very happy with the service.

Good To Know
Q: How do I know if this thermostat fits my engine? A: Verify your engine serial number against Perkins model lists for 1004-40, 903-27, T4.236, 504-2, or T3.1524, and cross-check the 4W-8063 or 1447384M1 reference on your existing thermostat.
Q: What happens if the thermostat sticks closed? A: A stuck-closed thermostat causes overheating and potential engine damage, so replacing it with this calibrated 82℃ unit restores proper coolant flow and temperature regulation.
Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
