Is there an accepted mounting point for the temp sender for an electric fan? I am adverse to drilling holes, so I'd like to avoid that.
Any on/off temp recommendations?

I used this which fits in the top hose -

you may well find something similar locally - it's a good idea to wire it in to a fused permanent live. Generally the fan does not come on in free moving traffic but will come on as soon as you stop.

The fan I got from Delta many years ago had a tube-shaped temp sensor that was to be inserted into the radiator cooling fins towards the top of the radiator. This has been working well for me.

thanks for the info. I'm certain I'll use one of those methods.

Here is a picture of how I installed it.  I had to drill the holes to mount the control module.  The control just has a trimpot to adjust when the fan comes on, no indication of the temperature.  The way it is adjusted now, the temperature gauge in the cockpit stays midrange when the car is idling in the garage when I am working on it and the fan runs less than 25% of the time.  Hope this helps.

I had a system like that on my 429 Torino in the good old days.
I also like the in hose sender, Edd China approved you know.

Use a T-piece in the top radiator hose.
I have soldered a threaded bung in the top radiator tank. I think it was M22 for which thousands of different range sensors are available, so plenty of scope to experiment.

I wound up using the hose adapter from these guys.

They also offer temperature switches. I got 200 on 185 off....works awesome

I have a European specification intake manifold and what I did was drill and tap a hole next to the OEM sending unit for the gage in the dash. I put a 160° Deral electric switch in this hole and it switches two relays for the pair of fans I have pulling on the Champion 3 row core radiator. The only time the fans turn on is when the car is warmed up and not moving when in slow traffic. Cold mornings no fans, warm day and moving swiftly no fans. Works awesome, with a 160° thermostat in Southern California.

that's a very well thought out modification.. I like it..do you have Zenith or Dellorto manifold...I assume Euro spec mean Dellorto but I'm usually wrong when I think I'm right...what was the thread [if you remember]
