I am going to install this fan into my GTO and would like some detailed instructions on how best to wire the thing up.

Please.......... not trying to be nasty.....but I dont want to hear about alternatives.

I guess I'm electrically challenged since I cant find clear instructions in any of the old threads. Hopefully this will include how to put the sensor into the top of the radiator.

I am running a conventional 4-core radiator. I'm prepared to go to a 100 amp alternator as I understand these things will spike to 85A at start up.

Just get the hollister relay kit for it, money well spent. Its what i use.

Thanks, sounds like a quality built kit.

I see it says: "The sensor is a 3/8 pipe thread block mount type.....". Where/how did you hook up your mounting?

Right into your water crossover on the intake.

I'd like to avoid drilling my original tripower manifold.

Dont recall, but I wonder if there is anyplace on the block or heads as an alternate??

Where is the sensor now? Must be in the drivers head between #1 and #3 plug?

[mrtonegto]

The temp. sensor I'm using now is on the crossover, I'm running 5C heads, dont know what they'll show between #1 and #3.
I'll take a look................

Just found a pic of my engine that shows the pickup on the crossover and most of the driver's side head - dont see a spot there. Ground stud is there...............looks like something between #5 and #7 though.

[mrtonegto]

Here's a much better pic of a 5C head.

Nothing seems to show a location for a sending unit.

[grandville455]

Okay well if u already have it in the crossover whats the problem? lol.. If it isn't 3/8 pipe u can get a adapter then.

[mrtonegto]

Hey, you've got a point there........... except the sending unit I have now has the tube running to my gauge (mechanical).
Must be another solution............. anybody got ideas??

[mrtonegto]

Or for $20 + freight I could go with one of these:

Next to the second spark plug on the vertical portion of the head, marked with a red arrow. That slightly raised place, There is a threaded plug there. That is where the temp sensor is mounted on my 79 TA. remove the plug and mount the fan sensor there.

See Grandville455 - you were right!

Thanks Ollie.
