Default Coolant fitting location

Is there anywhere else people are putting the sensor for coolant temp other than on the drivers side head? It seem right next to the header, so I am unsure if I am getting a good reading. I am working with a 1999 LS1!! Thanks for the help!!

You can put the gauge sender in the passenger side head rear as well. That way, the computer gets its sender and you get yours.

Default As Patrick says...

I'm using autometer guages, with the 12mm adaptor from Autometer it bolts right in to the passenger side head in the rear.

I put a VDO sending unit in the water pump on the round casting boss next to the TB cam/arm. Drilled and tapped it and it works like a charm.

It is also a great place to bleed air out of your cooling system as it is the highest point in the motor.

You get a pretty accurate reading from there?
