I am putting a set of aftermarket gauges in my 06 GT wondering what best way/location is to install temp sensor? Thanks in advance guys!

An splice in adaptor in the upper radiator hose is one of the easiest ways, I run the glowshift one. You could drill and tap the coolant crossover as well.

There is a location on the driver's side of the block. I put mine there. It is about 3/4 ways back from the front.

I think I like the idea of having the sensor located in the block anybody have any reasoning for why the splice in the upper hose would be better? Is the engine hotter up at the top of the engine such that putting it on the upper radiator hose would be a more accurate reading of the engine temp??

Found a couple pics of the location.

Putting the coolant temp sensor in the crossover is more accurate but both should be close. My 98 crown vic has both a coolant temp sensor and head temp sensor and they both read pretty close.

Absolutely, that is your real "hottest" temp coming out of the motor. The freeze plug on the driver side is closest to the water pump discharge and hasn't fully equalized by running through the block and heads yet. The water pump pulls from the lower radiator hose and pushes through the block and then heads, then coolant crossover discharge is hot water out to the radiator to be cooled again, so there is always a temperature differential from top to bottom forward to back. I wanted to read the hottest temp as the water comes back out the motor to be cooled again. I also have a water cooled turbo. I use that freeze plug on the driver side to feed the chra which measures 150-160 degrees coming out of the block at operating temp and then measures 250-260 coming out of the turbo chra, I return that to the upper radiator hose as well to go straight to the radiator for cooling.
