Electric fans
I got dual SPAL electric fans for my new alum radiator, and when looking at the wiring, I'm not so sure where to fit the water themo switch except in the spot where the water temp sensor is.
What am I missing? Are there other similiar spots to put in a water sensor?
Yea, I know, Novice! :rolleyes:

There should be a matching port in the other head that is plugged. If you can't find one there, then there are usually ports into the water jacket of the intake manifold, that's where I put mine Spal temp sensor.

Re: Electric fans (Deslok)
I have a Spal 16". It works well. My Weiand 7546 manifold had a spot just to the left of the Upper radiator hose. That is where I installed the sensor (yellow wire). I got an 195 degree relay, get a 160 or 180. 190 is too high.

I got a thermostat housing at Schucks that had ports in it for sensors. Works great for me
Respectfully disagree with this.
I have the 195 sensor and I am using a 180 degree Hi-Flow Robert Shaw thermostat. On the highway (practically any speed above about 30 mph) natural airflow keeps it cool enough that the fans never come on. Around town (stop and go), it heats up to 195, fans kick in, it cools off, fans go off. I have NEVER broken 200 degrees.
If you have a fan sensor that is equal or less than your thermostat. The fans will run constantly. The Spals are great but they do pull a lot of current. The way mine is setup, the thermostat controls the lower limit and the fans control the higher limit.
My $0.02.

If I had a 160-180 degree thermstat, how would that help control temperature below 190 when my electric fan kicks in?

I am not sure what my thermostat is set for. My engine reaches 195-200, fan kicks on, engines gets to about 210 (sitting still or stop-n-go traffic). Once I get moving it goes back to 180 degrees.

I noticed you are using the single 16" vice the dual 11" fans. I wonder if that makes any difference.
However, I did have the same kind of problem with the heating. Plus, after the car got hot enough to turn the fans on, it never got cool enough to turn them off. That's when I tried the Hi-Flow thermostat (about $10 at Auto-Zone). It honestly works great and at idle or in traffic, the car gets up to 195, fans on, they run a well, and it cools right back down and they turn off.
I am pretty sure you are just not getting enough coolant flow. Cheap, quick fix. There is no better kind. :smash:
