Engine fan: automatic or manual?

I have to pull a switch to turn on the engine fan and cool the engine off in my 67 A. This seems strange as my 65 Coronets were auto fan cooled. Plus it makes the alt work really hard and I'm on my second one in 3 months. So my question is was the engine fan automatic or manual from the factory?

Thanks,

my fan is automatic i dont believe any A came with a manual fan but i could be wrong

so is it an electrical fan? - upon reading your post i have to guess you are saying an electrical fan is placing an increased load ( more current needed ) on your electrical system - but then i may be misreading - some more info should help - engine, stock or mods of engine / electrical - etc - oo3

Many moons ago I had a 67 A100 purchased from the original owner. It did not have a electric fan of any kind. The origianal fan was a steel blade which I replaced with a multi blade flex fan after the steel blade was damaged when a motor mount broke. I owned the van is So California and drove it to the desert and Baja Ca. Never had a heat problem. Engine was 318 with auto trans. Hope this info helps.

Mine is a 318/727 also. I think I need to dump the electric fan someone put in there and get the same one you put in. I wonder why someone would put in an electric fan??

It's hard too say why one would put in an electric fan in place of a standard fan if the cooling system was working as designed. Are you having cooling/ heating problems?

This is the fan that is in my van. I can turn it on without the key!



Not sure what this is. Maybe the voltage regulator?



Wires run all over the place! I really need to rewire the whole thing. My first kid is due in 2 weeks so it will have to wait a bit!



The white button in the upper right is the one set to control the fan. What was it?

No cooling problems when the fan is on. Not much for heat in the winter though.

Looking at the pics, it appears that the original steel fan was replaced by the plastic electrical fan. Installing a manual flexfan of the right diameter should eliminate the need for the electrical fan altogther. The installation requires using a spacer or two to set the correct distance from the back of the radiator tubes to the front of the fan. Comes with the fan. The flex fan changes pitch as rpm increases. Mine worked very well for quite a few years. Im probably preaching to the choir here but the cooling system is a balance of several components that need to be working together to provide proper cooling in the summer and proper heating in the winter. So bear with me on this:
Radiator : proper thickness and number of tubes and coils, clean inside and out.
Radiator cap: correct pressure and seals well.
Radiator shroud in place.
Correct thermostat installed with the right side toward engine.
Water pump operating correctly. Correct coolant mixture.
All hoses in good shape. ( I had a messed up by pass hose on mine, looked ok on the outside but the inside failed, drove me crazy all of one summer.

Looks like someone added the late style dual belt setup to the engine. Depending on what water pump pulley was used, there may have not been enough room for the stock fan, so an electrical one was used instead.
