I installed a mechanical temp gauge at the heater connection at the back of the intake manifold. Operating temp is right at 200. I have been told this is the hottest spot in the cooling loop. Has anyone else taken temp readings at this location?

I have mine hooked up there too, and on a hot day it doesn't go past 200 or 205. On a normal day it hovers around 195 or 190.

Thanks Rob. It appears to be coming down the more I run the motor. It has just been rebuilt for the second time. This time it's done right...I hope and pray :D

I run my temp gauge off that back intake water port also. It runs about 190 all the time. Using that back port does give a more accurate reading of temp and it's also easier on the temp line you have to run back thru the dash. I always have a habit of breaking those important lines when working on my engines.

Sounds like your in the correct tempeture range.
I also have the same setup with a mechcanial water temp gauge. 190 -203 degrees.

Newbie question....how do you connect the sensor in that area. My sensor is located at the front of the engine but it isn't screwed in! Just sits in the hole. The sender is longer than the hole it appears!

Get a pipe fitting from your local hardware store that will fit the heater hose and has a hookup/threaded fitting that will work for the sending unit to mount to the fitting.
Cut/splice the fitting into the heater hose and mount the sending unit into the pipe fitting.
In my vehicle both the stock and auxiliary gauges are working. Good Luck
PS: you will probably need an additional hose clamp or two.

Does the sending unit get immersed in the water? Or is it simply sitting in a metal housing that heats up with water flowing around?

Bliss is ignorance..

You prolly want a short enough fitting so when it's all threaded and tightened the sensor is actually in the path of the water flow.

Mine was up to around 220 or 230 before I set the timing right :eek: !!!
