electric fans

[crash-harris]

Too much power? Probably not, but 2350 [email protected] is incredibly good if it's accurate. I'm using 2 JDM 10"- 1730 [email protected], each on its own relay, (1st relay controlled by thermostat, 2nd relay controlled by first relay) and a 12" 1730 [email protected] on a manual switch. I made a shroud that seals with neoprene around the perimeter and blow-through flaps that open at speed but seal shut sitting still so only cool air is ever pulled through the rad (3 row aluminum). Towing a car hauler and Chevy Malibu in the summer from Jacksonville to St. Petersburg, my temp never went over 205°F. I'm pretty satisfied with these inexpensive fans, they're holding up so far and they're cheap enough to painlessly replace should one (or more) buy the farm.

That's good to know. What material did you use for the blow through flaps? I really like that idea.

I used .050" EPDM pond liner and pop-riveted it to the shroud.

Thanks

This thread has actually given me some confidence in planning out an electric fan mod on the Enterprise. I have previously been worried about our since our factory mechanical fans move so much air. I did see today that now the JDM fans are rated at a maximum flow of 1750 CFM when they used to be 1500 (maybe continuous flow). I'm thinking now about mashing 4 fans in there with your idea of "flow flaps" on a shroud. This setup would draw much less power than two 3.8L dual speed fans, be way easier to install and even a little shallower. Combined airflow with 4 fans would be 6k-7k CFM maximum. Also likening the idea of dual thermostats.

As of yet I haven't looked, but is there a factory plugged hole in the t-stat housing, or is this something that must be drilled and taped in the cast housing?

I drilled and tapped a hole for my temp gauge in the t-stat housing. im just not sure if I am going to put the sensor for the fan in the same place or somewhere else on the block.

 

[crash-harris]

One more question, what size/pitch did you tap it for? I'll have mine off soon and would consider drilling and tapping it, but I've also thought about using the gauge sender port on the drivers side head for my mechanical gauge and either buy or fab an adapter tube/fitting for the upper radiator hose for a fan controller. I've used the stick in probe type and got lucky enough to find a spot on Bruiser's radiator that I could slip it into without destroying anything, but I'd feel more secure with a probe in direct contact with flowing coolant.

 

[no mufflers]

I believe the sender was 1/8'' pipe thread and I had the tapered tap. its good cast so it went pretty well.

 

[crash-harris]

Good to know as well. I think I may go with the inline hose adapter for a probe. I'm way behind my own schedule on getting the Enterprise back on the road

Ok, hijack off.

Seems like the JDM fans can handle it after reading this thread and doing some deeper research. Those things are cheap on eBay and very easy to wire up. They are reversible as well.

Sorry I am just getting these posted, it was a crazy weekend and I am just getting caught up with Oilburners.....

Here is the fan and shroud setup for a 2000 P71 CVPI (Crown Vic Police Interceptor)

There are some subtle differences between the two. The 2007 one is a bit thinner as the radiator in these are slanted toward the engine at the top. This is why you can see the radiator in the 2007 pictures, but not the 2000.

Another side note, the P71's also have an oil cooler. In the pictures of the fan, look at the bottom of the radiator, if you see the "log" with 2 what look like hydraulic hoses curved into it, and the lower radiator hose in from the right (you can clearly see the hose clamp on the hose). This is an external oil cooler that replaces a section of the lower radiator hose. The lower on a Civilian Crown Vic is about 2 feet long. On the CVPI you cut both ends off and this replaces most of the hose. Just an idea of something that could be used to keep other fluid cool, like Power Steering (maybe) or even a fuel heater..........

If you need any other pictures, let me know. I have access to these 2 anytime.........

is that the same shroud for the engine driven fan and is it just replaced with one big electric fan?

What's that on in the pictures? I only ask because I noticed that the upper rad hose goes to the opposite side of the radiator then my IDI upper hose. I'm assuming it's the Crown Vic now that I notice the thin rad core It would offer a nice alternative to broken factory overflow reservoirs and add another good option for an auxiliary power steering reservoir. Would be great for hydro assist trucks or even hydroboost swaps.

is that the same shroud for the engine driven fan and is it just replaced with one big electric fan?

I believe it's a different shroud. The mechanical fan shrouds I've seen reach farther back toward the engine, since there is a large gap between the front of the engine and the radiator. I double checked this morning, the fan mount is part of the shroud, at least on the 2000, I am not where the 2007 one is at the moment...... It ls also just one large fan, not 2 like on the Taurus.......

Also what is the diameter of that single big fan?

These are on the Crown Vics listed. They are both retired police cruisers, and even on the hottest days, they keep the temp in check, and the A/C nice and cold.....

Yes, they do both have remote power steering reservoir, the 2000 mounts to the front of the engine, and the 2007 mounts to the core support. I would estimate they hold less than a quart... they are no where near as big and the remote reservoir on my 03 PSD that has hydroboost.......

The coolant bottle you are seeing is a really nice unit. The only issue I see is, it's actually a Degas Bottle and is under pressure. The "radiator cap" is actually in this bottle, and there is no cap on the radiator itself... Also, there is an ~1.5 inch hose that connects into the bottom of the bottle, along with a small one on the top....

If you look to the right of the hose clamp on the oil cooler, you will see a tee with a hose coming "up" toward the bottom of the bottle

In this one, you can see the hose clamp on the same hose, on the bottle itself, and the small hose that goes to the radiator.

I'm sure you could plug this hose, but I don't think there is a way to put the "suction" hose from an IDI into the bottle, and the large hose in the bottom is where the coolant leaves the bottle, back into the system.

I can get other pictures if you like......

kind of off topic but I have an OBS PSD radiator and bottle on my 91.

Good point snicklas. I'm currently planning on going the "go fast" route to replace my broken resevoir. Got one of the 3"x16" chrome reservoirs that mounts vertically. If for some reason it doesn't provide enough expansion volume my next step would be to mount another one on the other side of the radiator. Small town, slim pickings at the only junkyard in the next town over and I can do a trip to the Columbus pick n pull just to look for a good factory resevoir.
