Any advice or tips on installing elective cooling fan in '72 Dodge Dart Swinger? Thanks in advance ! G
What kind of motor do you have?
A slant can get away with a much wimpier fan than a stroked 360.
I run a 17" thermostatic controlled fan in my car, set up fully automatic and it works great.
When I change to the 360 Mag I'll have to change it out for a fan clutch setup because the electric won't keep up.
I have seen built V8's run 2 hi speed electrics with a shroud and get away with it.
The motor matters as to what you can do.
We always convert our 240's and 740's to run the later style Volvo 940/960 e fan. They are cheap and easy to find. They come with a 2 speed relay. I always wire mine up to run any time the key is in position II. In summer, I run it on speed 2 and on speed 1 in winter.
I started an install on my '68 with the 960 radiator as well....
I think that in many production RWD cars the extra electric fan is mainly for the AC. At least, in my 1980's M-B cars it only comes on from the AC refrigerant temp switch. You could also wire one to come on from automatic tranny fluid temp if using an add-on cooler. The after-market ones are fairly wimpy, but would help for above.
To really help, people like the Ford 2 spd fans from the 90's (Taurus, Crown Vic?). Much info on the H.A.M.B. hot rodder site.
I love what Rectilinear has done. A guy with a Volvo and Mopars, let's see what will fit. I try the same with M-B parts..
I have a 360 30 over forged TRW pistons, 508-292 cam in '72 Swinger. The car does not overheat, just looking for options.

Yes. Have a plan for if the fan quits with or without you knowing.
That raises the question why manufacturers of new cars don't add a sensor to indicate that the electric fan is commanded, but an open circuit (no current flow). Even easier would be a high coolant temperature audible chime (some might have that). Must be for cost. Almost all new engines have aluminum heads which are very sensitive to warpage from overheating. Our engines are much more robust and can usually run until the oil overheats before they are damaged. You could rig a temperature switch in the coolant flow (ebay) and wire to a 12 V alarm in the dash, but a bit of work.Yes. Have a plan for if the fan quits with or without you knowing.
