E.Fan control question
I recently completed a conversion to a dual fan system
I have an interesting problem since I did the conversion, and I wonder if you guys could help me out. Prior to the dual fan install I had the adjustable thermo control, with the radiator probe, mounted beside the radiator with the tube to the probe coiled up right there, and it worked great.
During the install I moved it up by the firewall, and ran the tube along the fender to the radiator. Now it doesn't shut off so easily as before. I wonder if the tube is picking up the heat from the header. I mean it is prob. 10" away, but could that affect it at a stop?

Since all it would take to move the control box back to that spot is two longer wires I say move it back and see if it makes the problem go away. Just my .02 and what I'd do to trouble shoot it.

Oops.
It is amazing how much better the system works (no blinking lights, no cutting out of radio when I apply the brakes!) now that I have installed a ground wire from the 3g alternator to the frame!
And ... I find that if the rad. is filled above the temp probe you get a better reading. It's all in the details.
Running at normal temp, stop for a minute, re start and temp is 220-230. That temp is normal, right?

That sounds about normal for a vehicle for temp....basically you quit moving the water when you shut the engine down and after a few minutes you get back in and start it up all the water that was in the water jacket will be hotter due to induction heating.
