About this item

  • LS cylinder heads are machined with metric M12-1.5 coolant sensor ports,This adapter allows you to keep your original sensors and integrate them into your swapped LS engine. We would suggest measuring the length of your sensor before purchasing this adapter.
  • Adapter has a female 3/8" NPT port, 0.85" deep.Converted 3/8 to the metric thread size on most chevy ls heads. Allow you to use your factory coolant temp gauge for your LS swap.Perfect fit to adapt older sensor to a newer model ls engine.
  • Must have when retrofitting electric fans to a Chevy LS motor with a painless kit ,perfect for adding Joel electric fans to a 6.0l Chevy.
  • Larlansz Precision threads never leaked or stripped any threads when installing.This adapter will fit all GM LS series engines.
  • Material: Aluminum AL6061,Package listing : 1 adapter & 1 sealing washer
  • NOTE:Don’t over tighten.


This is the best LS temperature sensor adapter, dont waste your money on the other kind.

The internal threads for the coolant temperature sensor were not tapped fully, I wasn't able to even start the sensor. I bought a tap and threaded it properly. Poor quality

Bought this to add a temp switch in the head of my LQ4. Quality seems nice and fit was great. Remember you are working with lightweight aluminum so don’t crank down when tightening. Zero complaints!Bottom line- will be buying another for a different project I have!

The end broke off instantly in the head. DO NOT BUY THIS unless you want to be running an extractor in your head.
