1337 Water Temp Gauge. I Got A Vehicle With This Gauge Installed But No Temp Sensor. Can The Temp Sensor Tapped Into Coolant Temp Sensor FiTech 60021? Id Like To Use The Existing 1337 I Have With That Temp Sensor. If Not What Sensor Do I Need

Asked by: S.J.S. Hayes
This is not compatible with the FiTech system CAN bus or sensor. It uses a simple resistance range of around 1100 ohms @ 100 to 65 ohms @ 250. We do actually have a FiTech compatible gauge here:

Can this gauge and sender be used to monitor automatic transmission temp? Will be used in a 700R4.

Asked by: Jim D
Hello, Thank you for your question. This gauge uses the same sending unit found in our transmission temp gauges. You can definitely use this for your application, but will need to locate a port on the transmission to place the temp sensor.

Zach, In the installation instructions it clearly says I should use Teflon sealing compound on temperature senders. Please explain your recommendations to use no sealant or tape.

Asked by: MoonBar2
You can certainly use a small amount of sealant, but it's important to know that a ground connection must happen through those threads. Since the sender is a tapered pipe thread, sealant isn't actually required.

Can the sender (2258) be used without sealant or Teflon tape ?

Asked by: MoonBat1
Thank you for your question. We actually recommend you do not use teflon tape on #2258 as the sensor grounds through its threads and teflon tape/thread sealant can lead to a poor ground connection.
