Good To Know
Q: How do I know if this sender fits my John Deere? A: It fits the 1550, 2155, 2355, and 2555 models, but always verify your serial number and thread size before ordering. The OEM cross-reference AZ35440 should match your original part number.
Q: What happens if this sensor fails? A: The temperature gauge will either read low, spike wildly, or stay at zero, which can hide overheating. Replacing it restores accurate monitoring and prevents potential engine damage.
Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
