LS Engine Swap Intake Plug Coolant Temp Oil Pressure Sensor Adapter M16 M12 x 1.5 to 1/8 NPT for All GM LS Series Engines LS1 LSX LS3 5.3L 6.0L 6.2L

I have a John Deere tractor and needed a fitting for a temperature sensor . this fitting worked great no problems 5 Stars rating

Wanted to hook a old school temp gage and it dose not work

Exactly what we needed

Did exactly what i needed it to bolted to passenger head at back for an added temp sensor for a ls swap i did

They actually work and fit well in LS1

This is advertised as fitting a 2005 Chevy LS head. It fits the head loosley and the compression washer is NOT a compression washer. Pressure check of cooling system exposed a leak at the left rear head, i.e., this fitting. Moderate tightening of the head to sensor adaptor resulted in the adaptor twisting off with the threads left in the head. Removed the broken portion from head, used a brass adapter and no leak. This is a cheezzie Chinerzze product.

Just what was needed. Came nicely packaged. They include aluminum washers. The threading external and internal is clean. They are aluminum tightening into aluminum which prevents galvanic corrosion but careful on the torque spec so you don't strip them out.

I used the adapters when swapping an lq4 in my s10. they seal well and have not leaked. they seem well built for the cost and adapting everything correctly. buying a set for my c10 swap.
