I asked this question on another Forum and got some interesting comments, wonder what some of you guys might have to say or maybe some thoughts on this subject.
What is the correct location for the Temp Sender on a SBC? Car is a 1957 Chevy running a 383 and a Muncie 4 speed. This is a new aquire for me and playing around with it I found that the Temp Gauge didn't work. I pulled the gauge and found that the sender was cut or broken. It "WAS" a cheap gauge and it also was manual using capillary tubing. This gauge was located in the drivers side head, in that spot on 350 heads were there is a plug between the # 1 and #3 plugs. I used this same spot as I could not remove the plug from the intake manifold. I installed a manual Autometer gauge.
Got it buttoned back up replaced the coolant, and went for a little drive. Temps after 20 min or so were a little high to say the least. After warm up the temp got up to 220º and then over the next 5 or 10 miles went as high as 230º. I came to a big hill with a down grade of a mile or so, shifted into nuetral and coasted down that hill at 60 MPH. Thinking here was engine would be at an idle and air flow would still be 60 MPH. That worked and it cooled down to 195º to 200º pretty quick. As soon as I hit level ground back up went the temps to 230º.
For me this is just to hot, engine runs fine and just doesn't seem to be hot at all, does not puke out the over flow tube, doesn't diesel like a hot engine will some times, it does really seem fine. But it is just to hot for me and something is not right. As I pondered this problem I got to thinking about that spot in between those two plugs. Is that a good place for the sender? I believe I have seen Chevy use that same location, or at least I think I have seen Temp Senders in that spot. Is that position between those two plugs and in the head a good indicator of ---Water Temp---?
