Where can I screw in a water temp sensor? #303668 04/30/09 12:05 PM 04/30/09 12:05 PM

The stock temp sensor is electric and threads into a tiny hole in the intake. The nice autometer gauge I got has a big brass fitting and I don't know where to plug it in. Where do you all put the mechanical sensor? the side of the block? Thanks Kevin

Isn't there a plug somewhere I can unscrew and screw in the sensor? The water moves all through the block right? I wasn't talking about a T... Anybody else? Where did you put yours? Thanks

A small hole drilled in the stat rim allows some flow with the cold engine. A lot of the performance water pumps don't even have a bypass provision.

The coolant comes nowhere near the gauge, no closer than with the electric gauge.

I'm thinking about going with the autometer electric gauge. It comes with a sender 1/4" npt. should be easy to drill and tap. That way I can still run the stock sensor- redundant I know but I can't stand to have it dead in my dashboard... Thanks

A small hole drilled in the stat rim allows some flow with the cold engine. A lot of the performance water pumps don't even have a bypass provision. I have yet to understand why such a large bypass & I have blocked it(no problems) & as Moparforlife says use it for a gauge location. You want the sender location as CLOSE to the stat as posssible(thats pretty much the hottest point).I would not drill shavings into the intake & the coolant will be hotter elsewhere than it is at the block drain. live every 24 hour block of time like it's your last day on earth

Quote: Great link, on another page they seem to have the fine thread to 1/2 NPT adapter. http://www.autometer.com/cat_accessorieslist.aspx?pid=9 This is how I do ALL my motors. I pick mine up at HomeDepot or Lowes. Any hardware store has them. Pull the plug from the intake (or just drive the car there, you will need a regular hardware store for someone to come out and look at it) and bring the temp unit with you and they can fix you up. 76' Volare, 5.9 magnum w/Iron heads.
