Ok, even with the FAQ there is still so much information about where to get parts in there that any installation tips have kind of gotten lost. I decided that I would break in the new forum and post the steps that I took to install ramcharger fans in my TPI Monte.


Ramcharger Dual Electric Fan Installation
___________________________________________________________________

Note:
I have a TPI system, so the wire set up might be slightly different
___________________________________________________________________

First things first: You need to locate the fan system. I ordered mine from an Authorized Vendor of this site, SMM Performance (Protouraero) at 219-926-9793 , but you can the set up at a local junk yard or Ebay.
Here is what you are looking for:

If you are getting it from a salvage yard, these are the cars to look for:
Chrysler Concorde 93 - 97
Chrysler LHS 94 - 97
Chrysler New Yorker 94 - 96
Dodge Intrepid 93 - 97
Eagle Vision 93 - 97 ESi or TSi

These all use the same fan set up, so any of these cars should work. Make sure you get enough of the wire system that you are able to splice into a custom wire harness.

Other supllies:
1. Wire Strippers/Crimpers
2. 10 Ga. primary wire (I used red and black, but any two colors will work as long as you can distinguish the power and ground)
3. 8 Ga. primary wire - the same two colors as the 10 ga.
4. Two automotive relays - I got mine at radio shack, but most parts stores sell them in the fog light section (make sure they are 30/40 AMP)
5. Heavy Duty zip ties or electric fan mounting kit (which is really just fancy zip ties)
6. 10 Ga. butte connectors
7. 10 Ga. FEMALE spade connectors
8. 8 Ga. FEMALE spade connectors

Optional Supplies (I used all of these, and will be referencing them):
1. Fused power distribution block (You need it to be fused, so I decided to do it this way in case I need to add any other electrical accessories)
2. 4 Ga. Power wire - from a car audio store
3. 2 Automatic temp sensors - there are several different brands and models. I used an Imperial part from Advance Autoparts that cost about 14 bucks, it is an exact copy of the Flexalite adjustable fan control
4. Cutlass radiator top plate - not necessary, but looks a lot nicer, and it is more secure.
5. Heat shrink tubing to waterproof wire connections.
________________________________________________________________

Ok, now that all the supplies are together, you are ready to get started. We will start with mounting the fans because it is the simplest.

Depending on the radiator you have in your car, some trimming/shaving may be necessary to get it to fit. I was lucky, and my fans fit perfectly between the tanks of the radiator. What you need to do is simply test fit it to see if any trimming is needed. This may be easier with two people, because it can be hard to line up the fan and keep it steady because you are bending your arms around all sorts of other stuff in the engine bay.

Test fit
1. Slide the fan down behind (in between the radiator and the engine) the radiator
2. If the shroud fits (it will be snug) in between the side tanks of the radiator, you are done. If not, keep reading.
3. Identify what part of the fan is hitting the radiator (usually going to be the 4 original mounting tabs)
4. Pull the fans out and trim - it will be easiest to use a rotary tool like a Dremel, but the plastic is fairly easy to cut with a utility knife (just be careful!).
5. Repeat steps 1 - 4 until the fans fit nice and snug.

Mounting
1. Pull the fans back out and lay them on a flat surface.
2. Using a drill bit that is big enough to feed zip ties through the hole, drill 6 holes around the perimeter of the fan shroud. I drilled one hole in each corner, and one on top center, and one on bottom center.
3. If you have push in type temperature sensors, push the sensor into the fins per the directions that come with the unit (near the upper left corner in an SS) and mount them in a location that is convenient for you. I mounted mine right on top of the fan shroud so they are easy to get to should I need to adjust them.
Picture - Temperature sensors mounted to fan shroud:

(The reason why the sensor wire is bundled outside of the shroud is because I previously had a flexalite controller and it crapped out, so I replaced it with the one from Advance after I already had everything mounted.)
4. Now feed a zip tie through each hole and through the fins of the radiator, around the side of the radiator and secure it back.
Picture - Zip tie securing fan to radiator, and zip tie securing A/C line:

5. Find an appropriate location to mount your relays and fuse panel. For me, this was on the inside of the passenger side fender (make sure that you are not getting in the way of the hood hinge). Go ahead and mount them so we will be able to run wires to them next.
Picture - Power Distribution and relays mounted to inside fender:

6. Install radiator top plate to secure radiator to car.

________________________________________________________________

Wiring

This is the most time consuming part of the install, so take your time. It is easier to spend a couple of hours doing it right the first time, then having to go back and do everything over.

I will list the steps that I took to wire everything and then I will post my wire diagram.

1. Locate a good 12V switched power source.
- According my service manual, the Choke Heater circuit in the main fuse panel is not used in V8 cars but still wired in. Look at the main fuse box, it is labeled "C/H".
2. Splice 8 ga. wire into the source you have chosen.
3. Run the wire through the firewall and into the engine bay and to the temp sensors.
4. Split (splice an extra 3 inch piece to form a Y) the wire and put two 8 ga. spade connectors on the ends. Now connect them to the appropriate terminal of the temp sensor.
5. The other terminal of the temp sensors will send the trigger signal to our relays, so connect spade connectors to some more 8 ga. wire and run the wire from the output connector of the temperature sensor to the 85 spade on the relay. (Do this for both temp sensors)
6. Use 10 ga. wire to run from your fuse panel (2 locations) to each relay. Use spade connectors for each end. You will be connecting these wires to the 30 spade of the relay.
7. Locate a suitable ground near the relays, and using 8 ga. wire, connect spade 86 of each relay to this ground.
8. Locate a suitable ground for the fans. Using 10 ga. wire, connect the black wire on the fans to that ground.
9. Connect each of the remaining wires (green and yellow for mine) of the fan to spade 87 on their own relay using 10 ga. wire.
Picture - close up of relays:

10. Use the 4 ga. wire to run from the battery to the fuse block.
Picture - close up of fuse block:

11. Install 30 AMP fuses, and test.
12. In order to set the temperature sensors, turn both of them as high they can go and start your car. Once your car reaches the temperature you wish for them to turn on at, turn the knob of one of the sensors until the fans kick on. Now, shut the hood and let the car heat up, once the temperature rises to where you want high to kick on, turn the knob of the second sensor until the fan kicks on.

OPTIONAL STEP: Connect A/C to fans. Many people think that it is necessary to have your fans on when your A/C is on, so here are the steps of how I connected the A/C to my fans.

1. Locate the green trigger wire for your A/C compressor (one of two wires that actually plugs into the compressor).
2. Splice 8 ga. (the color you used for "hot") wire into that green wire.
3. Run that wire to the sensor that you have set as your "high" temperature turn on. And splice the wire from your A/C into the output wire of the temperature sensor.

FINAL STEP
Use wire loom to cover wires and zip ties to secure wires!!! (I ran out of wire loom so in the pics, some of mine are uncovered) Unnecessary, but wire loom makes everything look professional.

Ok guys, here is an update of parts that I used and where you can get them:

Fan Controllers:
Hayden/Imperial 3653 from Advance Auto Parts
or
Flex-a-lite 31147 from Jegs

I would recommend ordering the one from Advance, due to the fact that these parts are actually made by the same manufacturer, you are literally paying more for the flex-a-lite name.

Fuse Panel
:
ATC Fuse Panel I located mine in a NAPA without having to order it. I would recommend checking your local parts store though. After I moved to a town with an Advance Auto Parts, they had the exact same thing for about 5 bucks less. It just depends how much electrical equipment the store carries. It is Buss BP/15600-06-20, in case you want to order it from your local parts store.

Couple questions... do you have to upgrade your alternator with this setup? Do you know the part numbers of the fan controllers at advanced auto and also the part number of temp sensor? I couldnt find it online. Im trying to do the exact setup as you.

Unless I missed it the post, from the fans there are three wires.. One black ground and two others. If you want to have them both kick on full with one sensor, can you just splice them together with your hot wire? Know it sounds simple but want to make sure.

The two wires power both fans. Power one and both fans run on low, power the other wire and they both run on high. Its not for one or the other.

It's not an aftermarket part. The fans are off of a Dodge Intrepid. If you have any junkyards where you are at, that would be your best bet. You might be able to find them at a dealership but that would make them more expensive than aftermarket units probably. I'll let you translate. I don't know of any good translaters.

I found my fans at the junk yard for $25 and jes got my wire harness from ebay yesterday for like 30 sumthin. I got my fans off a 1998 dodge stratus. From what i understand...many of the late 90s dodge vehicles will have fans that will fit and work.

Encontre un ventilador como el recomendado, me costo 160$, en Venezuela los repuiestos son muy caros y no se consigue de todo, tenemos que ingeniarnosla.
Pronto subire fotos del trabajo.

I found a fan as the recommended, cost 160 $, in Venezuela the spare parts are very expensive and fails all, we must come up us.
Soon upload pictures of the work.

so it worked out for you just fine? I was concerned about the amp draw on the controller, might be using this as well. I'm between that and putting my own stuff together based on what others have showed me.

If this was already answered, I apologize. Does the alternator need to be addressed at all with this upgrade? I just picked up a dual fan from a 96 Intrepid and a top plate from a Cutlass and am gonna give this a go this winter. Thx

Yes, upgrading the alternator is almost a must if you sit in traffic, but if you are always moving and run a temp switch than it's not as necessary, but definitely worth it.

I ran the factory replacement alternator for awhile in mine. Only time it became a problem was at night when the lights were on too and in the winter when the heat was on. I later upgraded to the cs-144 or whatever and it cost me only $40 so it was definitely worth it.

As an FYI, CAspers electronics makes a stand-alone harness for teh ramcharger fan setup.

for my GN, all we did was cut the 4 tabs off the fan shroud and utilizing a new F-body radiator (3rd gen) the fan assembly literally snapped into place.

I'll be doing the MCSS soon, as my stock radiator developed a pinhole leak at pressure... frown

As an FYI, When I installed these fans on my GN, I bought a bolt-in harness from Caspers Electronics that was plug and play for the GN.

They also make a stand alone unit for cars that came w/out electric fans that you'd retrofit (like a MCSS)

I used a new 82-92 F body aluminum radiator single HUGE core. It utilizes the same core dimensions as the G-body.

You trim the mounting tabs off the fan housing and literally "snap" the fan assembly onto the radiator. you can cut a shallow groove into the shroud so it wont pop out, but its likely it wont do that anyway. mine is untrimmed and works just fine.

Now that the radiator in my MCSS has decided to slow leak, I guess that one is next.

been reading and rereading your post on installing these twin fans.
How have yours held up?

GOing to do the same with my ride , but it's a 82 Buick Regal, with a Buick 455, currently get cooled by a 86 GN electric fan and Radiator, tho not very well.

I noticed on most other boards they are using the "Ramchargers" style fan, wich is the 98-04 Intrepid/Stratus style.. does yours function any different or better?

In your pics in this thread it looks like your using the "ramcharger" style, or are they the earlier 93-97 style?

Thanks

Richie Cat thanks for the pics and the info..just finished installing mine and the basic hardwire.
I have a couple of questions on these 93 fans..one is in your pick is the plug-ins are mounted at the top,mine are on the bottom.
Also the green wire on the one fan.. is it a Hi or a low? I Have both mine wired red for power, and the black fir ground, when testing them before final install, the 3 wire one dosnt sound powerful like the 2 wire one...
I will post up pics tommorow

Putting the plug on the bottom is the correct way if you want the drain holes for the shroud on the bottom. When I tested mine it felt like the larger motor spun faster than the other one (on low and high speed) so I installed the fans upside down so that the large motor fan would help with cooling the incoming water to the radiator. I don't know if it really matters though.
My plug has green, tan(yellow?) and black wires. The green wire made both fans run faster so I used that hooked to my AC circuit.

I have my fans installed upside down. Wanted the bigger motor towards the hotter side of the radiator (coolant in). It felt like that motor pulled a little stronger than the other one. The green wire is for high speed.

I like your Idea of the stronger motor on the drivers side, I may do that, I want to keep the shroud mounted as is , but it looks like I can switch the motors from side to side.

Mine came with no additional wiring, just the solenoid/relay box in the the middle between the fans, ( it had 3 wires , red,green,black going from it to the the big fan motor, and only two wires red and black to the small fan motor)no plug going into that solenoid/relay.

Was it suppose to remain in?

I cut mine out and hard wired the red and black wires from each motor to relays and they both turn on together, to me they seem to be the HIGH setting.

The hard wired the green wire from the bigger motor to its own relay. when powered it seemed not as strong.

I found out that using one of the blank spots in the fuse block for switched ignition source was making both my fans and starter fight for the same juice.

A freind of mine who owns a GN , made mention that there is a brown wire behind the glove box that has a female spade type plug on the end and it's not used in most Regals , it is for a power trunk release.
It is not energized when starting the car,and the key is all the way foward, so that's now my switched ignition source.

Now with that said I picked up and installed a 3 position switch one off and two ons.

I wired from that brown wire to that switch then from there two wires to the relays, one wire runs both relays for the HIGH fan , and the other runs the relay for LOW speed.

So now I have one fan running at normal speed for cruising on the highway or the backroads, and then if it gets to warm 0n temp gauge, I flip the switch and got now two fans running HIGH !
