I was thinking about installing an electric fan to assist engine cooling on
a short term basis...such as the loooong haul on the I-40 heading east out
of Albuquerque !.

Is there room to 'pull' air in by mounting the electric fan between the
inside of the radiator and the blade on the clutch fan? Should I just
mount it flush to the air conditioner....whatever it's called... I can
never get A/C parts sorted out by name,... and push additional air into the
rad. There is not room enough to mount 'between' the A/C thing and the
rad.

I had one several years ago out of a Benz (about 12") and it seemed to work
pushing air. This one is 11"

Just looking for the best method...suggestions welcomed

Can I assume you will be on your way to Dothan, Mike?

As a newbie I'd sort of like to have some company on my journey.

Yes, I-40 eastbound from ABQ is a long haul until you get over
the hump around Edgewood. I think my GPS indicated a bit over
6900 feet elevation right around Cline's Corners just after the
first of January (NOT in my GMC).

Not much more complicated than installing a fan, and permanent, check out Armand's air flow deflectors

Hmmm, I might make a spoiler when I get home...thanks for the link.
On a long up-hill, an air deflector might not be much help at 30MPH
<g>....but on the highway, a good idea.

I don't know if you have a tachometer, Mike,
but you need to keep the RPM up and not lug
the engine. In my 2012 Flex with 355 hp on
tap, I did the upgrade on I-40 out of ABQ
locked into manual 5th gear! I wanted the
engine to be breathing free and not lug.

I realize we only have three ranges in the
GMC, but running in second gear with RPM
at 2500 to 3000 would seem to me to be a
good target, regardless of the actual speed
you can attain/maintain. I think both your
engine and tranny would thank you.

I'm sure others can provide more personal
guidance on this.

Almost all of that stretch of highway has the
extra "truck" third lane at the right side.

Sorry but I'm prone to exaggeration <g>
I do haul it into 2nd gear for the long ones and 1st for special
occasions...like Mt Rushmore.

I sent you a note off net re Dothan

Talk to you soon.

Mike,

I had an electric pusher fan that worked fine (until the bearings died).

The GMC that JimB and I drove from CA to FL had a "mister" hocked up to the water tank that seemed to work even better.

Both work that I can see.

I was going to post on this subjecty a couple days ago.

How many owners have entirely eliminated their engine-driven fan?

FWIW: I thought the fan and belts contributed enormously to the noise level on the flight deck. There certainly have been plenty of posts about the "roar" when the fan "kicks in".

PS: I've had a couple V6 Honda/Acura motors in the last few years and they are as quiet as any luxury car (Quieter, actually, than my last Lincoln) in large part (IMHO) dues to the elimination of the entire fan driving mechanism. Also, my Lotus 7 replicar - with chevy V6 motor only uses an electric fan and it is remarkable how seldom it needs to cycle-on.

Mike,
My experience with ele fans is that they tend to block too much ram air
when installed in the "pusher configuration". The OEM setup is very
capable of keeping coolant temps within tolerances under any condition.
Any additions (other than the new alum radiator) are bandaids.

Jim,

IIRC somebody (NOT JimG) that used to hang around here installed a couple of large "T" Bird fans and to do so he had to install a
larger alternator to drive them. When Bill Bryant mentioned that he has had his GMC for something like thirty years and never had a
cooling problem that somebody "flamed" him.

Rob M.

the way I see it, there's a reason all the pickup trucks and vans made
by the likes of Ford and Chevy still have engine driven fans, years
and years after they stopped putting them on their cars.
Though Chevies do sometimes have small electrics on the front to help
the A/C condensor coils get airflow.

The modern e fans on trucks are more for low speed air cond and don't block the entire condenser. To go to all e fans you would need dual belt alt drive and soft start on the fans through low speed resistors and relays. Won't match clutch fan. My GMC never runs hot in traffic no matter how hot out. It's the road load heat thats hard to get rid of and the clutch fan will get that done when needed.

I suspect it's substantially cheaper to use a belt when the engine is North - South; whereas a sideways install is likely cheaper to do electrically.

Well see, that's what I was trying to get at. Even on longitudinally
mounted, RWD, V8 cars like the Crown Victoria, Ford was using electric
fans only. (since that car's gone now, 'is' is the wrong word) but on
trucks like the F150, and vans, like the Econolines, they used engine
driven fans. In many cases, these trucks and vans had the same engine
as the crown vic, except with mechanical fan.

(i can't speak to the most recent model years, with EcoBoost engines
and such, having not seen what they look like under the hood, and the
newest GM with a longitudinally mounted engine i've looked inside of
was my uncle's '99 Suburban)

What I'm trying to say is: Our machines work hard, maybe (probably)
harder than the vans and pickups I've mentioned. The manufacturers
know what they're doing, (a million F150s a year can't all be wrong!)
and that is putting mechanical fans on their harder working machines.

Patrick,
You've got it right. The GM trucks until very recently always used mechanically driven fans because they are made to live under a higher load condition including max gvw plus max trailer up to the gross combined weight rating up Baker's grade outside Death valley with no abnormal temp readings.

I think maybe 5 or 6 years or so ago, on 1/2 ton GM pickups they went to electric fans to help with fuel economy. They are more efficient in that respect, but the mpg differences are measured in the numbers right of the decimal point that are much more valuable to manufacturers that need to meet Corporate Average Fuel Economy regulations than they are to consumers who only register fuel economy improvements in the range of several whole mpg. I think the 3/4 ton and above trucks are still belt driven, partially because of the heavier loads, and partially because they are not counted in the fuel economy rules.

Something that is probably not intuitive, was a lot of the early use of electric booster fans on trucks was with snow plow prep packages. You wouldn't think in the winter you'd need them, but if you are going 5 mph pushing a lot of snow, and have a big plow in front of the grille, there were some overheating issues.
