Re: Where do I install sensor for mech. temp guage
Don't know what engine you have, so I can only help you out with a 258. Under the intake/exhaust manifold, just in front of where the exhaust manifold connects to the pipe, you'll see a pipe plug. That goes into a cooling jacket. Take that out and put your sender in there. Do it with a cold engine because antifreeze is going to pour out, unless you drain it first. You should have gotten some adapter fittings with the sender, eyeball the plug to pick the one that's closest, make sure you have everything ready and go like heck. That's what I did, and then top off the radiator!
