for those who have added an electric water temp guage, where did you screw in the sender?

 

Since no one else has responded I thought I should atleast give some advice. Plant it somewhere before the thermostat in the radiator so you can be sure you get the reading of the temp of the coolant before the thermostat opens.

Sorry, I haven't done this, just giving advice.

 

Look just above the oil filter. There is a drain plug in the block that is 1/8"NPT, the same as an Auto Meter sender. Coolant WILL come out, so be prepaed to get messy.
