New to the site and am in search of some information about what type coolant temperature sensor to use and the preferred location to install it. Just purchased a BullyDog GT and it has the option of placing the programmer in "Engine Warm-Up Mode" to allow the coolant temperature to reach a certain temp before applying the tunes. Thanks in advance for any info!

If you take the cap of the reservoir bottle, it should take the vacuum out of the system. And if you are quick enough with the plug, you shouldn't loose that much coolant.

This port in the side of the water pump housing is plugged with a 5/16" square drive 3/8"NPT plug. Simply remove the plug and install a 3/8"NPT to 1/8"NPT adapter and screw in the sender. On this 2000 Ford 7.3L Powerstroke we are installing the water temp sender in a "T". This is due to the customer's installation of an aftermarket coolant filter requiring a hose connection.
