So I picked up this GTV a few months ago. Im preparing the car for a road trip from seattle, wa to monterey, CA. I picked up a set of alfaholics 15x7 GTA reps. And now installing the electric fan conversion. I searched for fan kits and couldn't find exactly what I was looking for, so I ended up sourcing parts from two different suppliers. I'll list the parts below. I knew I wanted a proper fan switch, not the type you push through the fins on the radiator. I'm sure these work just fine, but I really didn't like the look of it. A clean engine bay is a focus of mine. I also wanted a proper relay and circuit breaker. JEGS of all places had a very nice 12" slim line fan and wiring kit with relay and circuit breaker. The kit also included a 3/8 NPT fan switch in a temp range I believe would work just fine, but I ended up not using it. I wanted to use a radiator hose insert for the fan switch and couldn't find one with a 32mm or 11\4" diameter that had a 3/8" NPT thread for the switch. Alfaholics does have one and it comes with the alfa fan swith. Both were around 60 dollars. I think this should be a nice combination. I'll post updates of the installation. There is probably already a thread on this subject, but couldn't hurt to have one more.
-JEGS #52131 12" ELECTRIC FAN
-JEGS #10560 Electric Fan Relay Switch
-Alfaholics Electric Fan Thermostatic Controller-In line hose version.
Good move. The switch housing can be sourced from an early 90s Saab Turbo and you can use an Alfetta radiator fan switch. Here is my junkyard pipe for $5 and a $20 Alfetta switch. Yours looks like it's aluminum, though. Beautiful.
I wired mine directly off the alternator though and did not use a relay. I want the fan to stay on after the car is shut off for a bit to cool off the car.
Good info to have. Yeah, the alfaholics swith housing is aluminum and I'm very pleased with it as I have been with the other items I've received from them. I am using the same switch as you too. It is included with the housing.
What is your motivation for installing an electric cooling fan?
BTW, SPAL makes a "12 inch", low profile high output fan that is a perfect fit between the radiator and coolant pump in a GTV 2000. It is like this Italian company, SPAL, designed it for this ALFA. I've had one as a puller in a GTV for a better part of 14 years and 40K miles. Works flawlessly as does the PSM controller.
Cooling as a pure function of engine temperature is the best way to cool. The only reason to keep the engine fan really is for originality. I've also heard fear that the electric fan could fail someday. Sure, that risk is there, but all cars today just have an electric fan, so I don't hold that fear.
Very nice! I'll try the temp switch I have currently, but I love the idea of an adjustable. I'm going to mount with able too. I just can't bring myself to use those plastic mounting clips provided. I was planning on aluminum, but otherwise just like yours
Didn't have a lot of time to work on the car this week, but managed to install the online fan switch housing. I took this opportunity to flush the system a bit, bleed out and air, and to her off. Hopeful I'll find time to install the fan and write it up this weekend.
