can someone tell me how to put a water temp gauge in i have a 96 gt with a 98 motor . any help would be great . thanks

 

Not sure if you're talking after market gauge like auto meter or what...

Here is what it says for 98 mustang on Auto Meters web site:
Water Temp Location and/or Thread Size
for 4.6 engine(s)
Look below the last freeze plug on drivers side (left side) of the block. There will be a threaded in plug (16mm x 1.5). This can be accessed and removed from under the vehicle. For electric gauges use an Auto Meter model #2268 adapter. For mechanical gauges use an Auto Meter #2275 adapter.



Also I just did a write up how to install electric oil pressure and water temp gauges on 99-04 4.6's here: https://mustangboards.com/reference-...ure-gauge.html

 

I think the only place to put it is on the side of the block on the drivers side. I believe it is a 17mm bolt head on a pipe plug and is about half way down the block and closer to the rear of the block. Hope this helps.
