Product Information

Full details

This Mishimoto Water Temperature Sensor Adapter is designed for automotive enthusiasts and tuners seeking precise engine coolant temperature readings. Its key benefit is enabling accurate sensor placement directly in the radiator hose, bypassing potential inaccuracies from engine block placement. A primary consideration is that installation requires cutting the existing radiator hose.

FAQs

What is the main purpose of this adapter?

The primary purpose is to provide an optimal location in the radiator hose for installing a water temperature sensor, ensuring more accurate readings of the engine's coolant temperature.

Do I need to cut my radiator hose to install this?

Yes, installation requires cutting the radiator hose to insert the adapter.

What size sensor does this adapter use?

The adapter features a 1/8" NPT sensor bung, which is a common size for aftermarket water temperature sensors.

What does the '38mm' designation refer to?

The '38mm' refers to the inner diameter of the radiator hose that the adapter is designed to fit.

Does this adapter come with a temperature sensor?

No, the adapter is sold separately and does not include a water temperature sensor. You will need to provide your own compatible sensor.

Can I use this on any vehicle?

This adapter can be used on vehicles with a 38mm inner diameter radiator hose and a 1/8" NPT temperature sensor. Compatibility depends on your specific vehicle's cooling system dimensions.

Will this adapter affect my cooling system's performance?

When installed correctly, this adapter should not negatively impact cooling system performance. Its function is solely to provide a mounting point for a sensor.

Troubleshooting

Coolant leak from the adapter

Ensure hose clamps are tightened securely. Verify that the hose is properly seated on the adapter barbs. Check the condition of the radiator hose for any cracks or damage.

Inaccurate temperature reading

Confirm the sensor is fully threaded into the adapter and is functioning correctly. Ensure the adapter is installed in the main radiator hose, not a heater core hose, for the most accurate reading. Check for any air pockets in the cooling system.

Difficulty installing sensor

Ensure the sensor's threads are clean and free of debris. Apply a small amount of thread sealant specifically designed for coolant systems to the sensor threads before installation. Do not overtighten.
