Frequently Asked Questions

What does a coolant temperature sensor do?

It monitors engine coolant temperature and sends a signal to the EFI computer to adjust fuel mixture and trigger the cooling fan at the correct threshold.

Is this a direct replacement for the OEM sender?

Yes — this SMP sensor is engineered to match OEM specification and bolt into the stock location.

Will this fit my Harley or Indian?

This sensor fits V-twin EFI motorcycles. Verify your bike uses a coolant temp sender in the thermostat housing before ordering.

Do I need a tuner with this sensor?

No — as a direct OEM replacement sensor, no re-mapping is required. The EFI system will recognize it immediately.
