Hi Guys,
I'm new here. I inherited my 87 GN last year from an older friend of mine after he passed from cancer. Car is a clean 87 GN with 28k, body is clean garaged but had a lot of issues I'm sorting out and the radiator was one of them. Stock radiator was completely plugged so for a temporary fix I found the aluminum replacment radiator with the plastic tanks that was drop in. I live in Sacramento so I know when I fix the AC the stock fan and that 1 row radiator won't cut it.
Coming from European cars, I kinda like to over complicate my modifications. I live in a pretty hot area during the summer. I will be using my AC a lot and wanted to make sure It had sufficient cooling. I know the intrepid fans work perfectly fine as an upgrade, but having used PWM fans on other cars I am going to do the same to my GN. Also the variable speed is nice especially because you don't have to hear the high speed Fan constantly when not needed.
Scored and NOS aftermarket aluminum radiator from Facebook market place.
Found a bunch of info on pwm fan conversions from: Brushless Cooling Fan Conversions
Also just ordered PWM fan controller from ebay:
Since it was labor day weekend and pick and pull salvage yard had a 40% off sale I tried to look and some chevy volts that they had. All of them were crashed in the front or fans were missing
OEM used fans on Ebay run anywhere from $250-$350. Too much for my experiment so I called a local dismantler and he had one for $100. Just picked it up and it is the perfect size.
I store the car at my father's house during the summer because it's cooler there but will have it back here in a month and will update with the progress. If anyone else has done this conversion, please chime in if it doesn't work or any hurdles you may have encountered. Looks pretty easy though. I work on cars for a living and electrical is my specialty so the wiring should be cake.
I have attached a picture of the new aftermarket aluminum radiator and a picture of the Chevy Volt fan on the original GN radiator.

VARIABLE PWM FAN CONTROL works with ANY sensor, compare to Lingenfelter VSFM-002 | eBay
It also has special selections for driving Solid State Relays (SSR's) to vary DC fans with no fuss. Easy 2-button programming makes setting the temperature span a snap, just run the engine and press one button at your "turn on" setpoint, another button at your "full speed" setpoint.
