livanda Posted March 28 Share Posted March 28 I'd like to add an aux coolant temp guage and keep the stock working. Any other place I can pull a plug and replace with a sensor? Link to comment Share on other sites More sharing options...
Febreze Mee Posted March 29 Share Posted March 29 (edited) Welcome to the forums Livanda! Please take some time to visit the New Members section and give a small intro. As for alternative temp sensor locations, I have an auxiliary coolant temp gauge mounted, and I plumbed into the back of the coolant cross over pipe. I, too, wanted to maintain my factory coolant temp sensor. On the pipe, catty-corner on the other side of the factory sensor, you will find additional metal real estate from the casting. This proved to be a great spot to drill and tap for 1/8 PT sending unit. If you decided to go another route, any one of the ports you plug a block heater into would suffice, so long as you had the right conversion plug to fill it, so the new plug could take a temp sensor. Here is an example of what my set up looks like for my water temp gauge: Coolant temp gauge circled in yellow above. The red circle is where I tapped. And the red arrow shows the route I took with the wires. Edited March 29 by Febreze Mee MILKRUN - Click Here Link to comment Share on other sites More sharing options...
