I think my fan assembly is missing

seanmathes · Post by **seanmathes** » Mon Sep 25, 2006 7:48 am

On the passenger side of the engine there is a pulley, but there isn't
anything attached to it. At first I didn't think much of it but then I
realized there really isn't any type of cooling for the engine. I
couldn't find any good pictures of the engine. Can anybody tell me
what I am missing? I have driven the car about 100 miles so far,
should I not drive it anymore until I get that. Does anybody know if I
am going to be able to find what I need to replace it? Thanks

I contacted the guy I bought it from and this is what he said:
Hi Sean,
Appearantly there has never been a fan on it since I owned it, I don't
remember ever having any work done on the engine.
He has had the car for over 20 years! Is the fan not that critical for
operating temperature? I can't imagine why anybody would take that off?

THe pulley leads to the cooling fan behind the engine. The last I checked Miles was selling some new pulley belts for this on ebay.

But there isn't any fan on the back of the engine. That is why I am
confused I am not sure what is and isn't there. Can you visibly see
the fan between the motor and the cowl?

What year is your car? The fan assembly for the 1970 and early 71 is different from the late 71 and 72 model.
I definately have one from a 72 and might have one from a 70 soon.

My previous 72 coupe the original owner had the fan assembly removed
on the engine, im not sure of the reason either, he actually removed
the pulley off the crank also and replaced it with a spacer.

The car is a 72. What parts do you have for the assembly, does it
include the entire housing for the fan, etc? Please let me know and
what you want for it? Thanks

Maybe they are removed for performance reasons? Without the belt and
extra pulley there would be an increase in horse power I think, that
is the only thing that I can think of.

Yep, it will have the entire housing for the fan. I can get you pictures soon. It's currently on my engine, but the engine is coming out next week.

Running your engine without a fan, you can do that. But I wouldn't, in
fact, I have put oil coolers on Honda 600's because of the heat that is not
removed by the fins (loaded with dirt) a fan that is not sufficient after
there are a number of miles on the car. Heat creats wear, more heat more
wear..... I ran a test of engine oil temp by having a oil drain plug made
to accept a oil temp sending unit and watch the temp of the engine oil
during different dirving conditions. Freeway driving the engine oil stayed
at roughly 170 to 180, 5 minutes off the freeway and at the first stop
light, it was hitting 250 to 280. And that was with a fan attached and
running properly. With a oil cooler it gets up to 190, and I have not
observed it getting higher on or off the freeway or during in town driving.
