I think the contour fans both pull the air through the radiator. That one has a puller and a pusher. Something to take note on. Blowing hot air from the engine bay over it isn't going to help much. I think one is the main fan and one is the condenser fan. That would be silly for them to be blowing opposite directions but I will have a look.

The front ac condenser fan and the contour fans work together and blow the air toward the engine. You could probably take off the ac condenser fan if you have contour fans but I see it doesn't hurt. And where is the 400.00 price tag from? In all I don't have 400 in the WHOLE swap. Let's not forget how much less drag is on that water pump now too. In all I'm as happy as a school girl and the engine and electrical is A okay with mine. I of course wired it properly too so that helps. I didn't have to buy a different belt with my HO alternator. In all it was a necessary mod for me. Is it for everyone? No of course not. I'm going on 200,000 and the fullmonty is actually going to the dealership soon to get a full check up. So I will update on that as soon as it's done. Should be Tuesday or Wednesday.

Maybe rapidly circulating the air back and forth over the radiator cools it. The Intrepid didn't have a grill per say, just the small vent in the bumper, so maybe that was the way around cooling issues. Don't know how well it worked. They could've flipped the blades or run the one fan in reverse but if they are two identical fans wired in the same fashion they will blow opposite directions because they are facing opposite directions.

So I will update on that as soon as it's done. Should be Tuesday or Wednesday. It seems I read another post or earlier in this post talking of $400 installed. That was using the other controller and the F5 is more than that one. Does your WHOLE swap include the HO alt. I gave $300 for mine and that's the cheapest one I found. Some are $1000. It is just extremely inefficient to take engine power to convert to electricity just to turn it into mechanical energy again to turn the fans. The electric fans were designed around transverse mounted engines as an engine driven fan doesnt work with the front mounted radiator. I think if the engineers thought there would be some benefit to this setup on every vehicle they would've made it oem. They also would've been able to integrate it into everything as efficiently as possible. It it was just some points to consider for those looking to do the mod. The water pump is driven by the timing belt.

Yes I can't remember if the nose is connected to the pulley or not. I just mean in general that's why there are electric fan conversions. The engine is spinning regardless of whether or not there is an electrical or clutch fan. The alternator is spinning regardless as well. I have seen no negative impact on the conversion. Only positive.

I picked up a dual fan setup from a 97n Dodge Intrepid today. I might have to return it because it's part of the wire harness and I haven't been able to find it anywhere. .... Cool! What about the depth? One of the problems I've run into is that some are too deep and place the fans almost up against the engine. Speaking from personal experience, that is not such a good thing.

I highly disagree with that statement JK. ... Also if there are add ons like an arb bar and lights you need that extra power. .... Likewise. And something that wasn't mentioned - the ARB does inhibit air flow somewhat. Adding lights to the ARB in the locations drilled above the winch (not on the bar, but the main body) will most certainly inhibit air flow. That may not be a problem or it may be. I have had mixed results. Edward

... The engine bays of the cars that these come out of are huge in comparison as well. No. Really? And you're the one talking about how bad spending $500 is? No. The condenser fan is unneeded with a sufficient electric fans setup.. Pushers are inefficient and using one to blow air against the air flowing into the grill would be completely ineffective. Post documentation that shows that's how that works. Edward

...It is just extremely inefficient to take engine power to convert to electricity just to turn it into mechanical energy again to turn the fans. A properly designed system will run the electric fan(s) around 60-70% of the time - or less - and not at full speed. As opposed to 100% of the time with a mechanical fan - at 30-40% to 100% speed. Engines typically need a fraction of the air flow that any mechanical fan delivers. They have to be over built to take in any and all circumstances wherein an electrical fan setup can be driven based on any data the engineers care to use that's available. That makes them more efficient at cooling, more fuel efficient and more emissions efficient. They are not used in 100% of applications because mechanical fan configurations are CHEAP. They have and they do. The timing belt is under the plastic covers. The water pump is driven by the external belt - the same one that drives the P/S pump - from the crank shaft pulley. It is not the timing belt. The timing belt drives the cam shafts and that is ALL it drives and it's driven off the crank shaft as well. Edward

Well its been about 2 weeks give or take since I took off the ac condensor fan. Ive seen zero change in temps. Seems to be doing good so far.

The '99 is going into the shop Wed to have the running boards removed and the rockers Rhino-lined. The bull bar and winch will be here by the end of the week. Hopefully I'll have everything else necessary to tear into the front by the end of next week. When I take the front off for the ARB, I'll have access to the A/C so I'll take a good look at all of that then. Edward
