I was looking for a mechanical water temp gauge for my '89 Wrangler -I6 and noticed most of the gauges in the 4WD Catalog were not compatible with the AMC 6cyl. Most were Autometer. What is the deal here, I thought they were installed in the same place as the sending unit using a piece of threaded pipe and a joint. Can someone shed some light on the problem with AMC 6cyl installation of temp gauges?

TIA,

There is a larger hole in the manifold, but it has the CTO valve in it. I guess you could tee in under the heater hose, but even that is taken by some smog setups with another CT valve tee'd in under the heater water outlet.[img]/wwwthreads_images/icons/frown.gif[/img]

There are two 3/8 pipe plugs on the drivers side,lower engine block that you could use to install a mecanical temp guage. You will probably need an adapter from autometer or stewart/warner to fit the 3/8 pipe. I used one in a V-8 AMC with no problem. (same size pipe plug)
