Cooling suggestions (fan)

-
Somewhere on here @goldduster318 did a write up on how to wire these fans up. I can't find it, but it used 2 70 amp relays (one for hi and one for lo) and a 60 amp maxi fuse. This setup was controlled by a Dakota digital controller. I set up my Taurus fans the same way. I'll keep digging for the write up.
I have a Delta Pag pretty straight H/L control. 1 40 amp inline fuse from the battery and a heat sensor to the radiator. Pretty bullet proof. I didn't check to see if the sensor wire may have come out.

The heat sensors can be problematic from everything I’ve seen. I run a Dakota Digital controller on the contour fans with a separate temp sender. For a Taurus fan that controller would actually be an easier set up.

But it sounds like there’s still some troubleshooting to do still. Check the sensor, make sure you’ve got power everywhere, that sort of thing. I hate tracking down all that electrical stuff myself, easier said than done. But if your setup worked well before it’s probably an easy fix once you’ve found the gremlin.
 
I've been reading about the Contour fan setup and was considering this as my next project.
But I went an measured and I have the 22" Champion radiator, and I'm seeing that the contour setup works on the 26" radiator.

Anyone got suggestions on a dual, or larger single electric fan setup that would work on a 22" radiator?

I believe the Taurus fan or the HHR fan is a single fan and works on the 22" and pull a lot of cfm.

I have Taurus fan on my radiator cooling a 470. On low at idle. in garage it will hold 180
all day. This is on a 26" radiator.
 
Good info , but still no worky worky on crossflow rad. .

:rofl:

That's funny, because the '95-2000 Ford Contours that those fan assemblies came from had a crossflow radiator straight from the factory. Works just fine. As long as the radiator core is a similar size as the the fan assembly you're good to go.

Do they attach at the top and bottom . Would have to match almost exactly to fit mine , core included . ------??

From the measurements on the drawing , no way would it fit a 22 wide x 18 3/4 tall core , w/ tanks on each end/no mounting-------------rigging it would surely be a rattler .

The Contour fan assembly attaches to the sides. It is also designed for a 26" wide radiator, which has been mentioned MANY times in this thread. It will not fit a 22" radiator, that's why the Taurus and HHR fans are mentioned. I mean seriously, are you reading this thread at all or just posting nonsense about a fan assembly you've never used?

And why are you commenting at all if you don't know how it mounts? You don't know how it mounts, but somehow you know it won't fit a crossflow radiator? Even though the radiator it's designed for is a crossflow?

C'mon man. If you don't know, either ask or don't say anything.
 
The downfall of people going with electric usually comes down to poor wiring techniques. If you use an electric fan(s) don't go with any type of electronic controller
use a simple capillary type switch with good quality Bosch type relays. Also have a
backup jumper circuit to bypass any controls to activate 12v directly to fan(s). Dual
fans can cover more surface area and also provide backup if one fails. Mechanical
fan is more reliable but leaves "free" power on the table.
 
I learned through trial and error (mostly error) and came up with what works well for me. A 16lb radiator cap to start (pressure equals a higher boiling point) a 195 thermostat (proper cooling is about heat transfer) and a 50/50 mix of good antifreeze (no more/no less) along with a good clutch type fan with a shroud. My cars run cool enough to idle through town on a 90 degree day without overheating.

I absolutely love my Dakota Digital controller. I can set virtually any temperature range I want for both the high and low speeds of my fans, calibrate the controller to pretty much any temperature sending unit I like, and even set post-shut down fan run times. You won’t get control like that with a simple switch, which leaves a lot of the capabilities of electric fans off the table.

Sure it works great until it doesn't like everything else, less room for another techy
failure. Do you really need or want to rely on extra stuff that can and WILL fail? I had it happen...more technology for the sake of technology.

Everything fails eventually. Thermostatic switches fail. Relays fail. Temperature senders fail. Fan belts, fan clutches, heck even water pump shafts and bearings fail. I have seen plenty of mechanical fan failures, they're not immune. And when they do fail, they take the radiator with them a lot more frequently than electric fans do. Modern electric fans are much more reliable than they used to be, and most of the problems people have with them are poor installations and improper triggering/controls.

And the Dakota Digital controller is not "technology for the sake of technology". You can not do what it does with just a thermostatic switch. One of the biggest advantages to running an electric fan is improving efficiency- running the fan only when needed reduces parasitic power loss, and keeping the engine in its ideal temperature range improves power. A digital controller does a much better job than a simple thermostatic switch.

You missed the point ''know it all " , I was inquiring weather it could be made to fit , looks like no way to me , I`m sure glad u are the worlds most authority on my car and everybody elses .
You can take ur egotistical comments and stick them where the sun don`t shine , tired of ur bulls--- T

I am tired of dealing with all the over engineered BS on cars. So many problems from
ECU, PCM GEM etc etc. Why put another layer on **** on a simple classic peace of mind car. I deal with this crap on a regular basis, now I need a PCM for my 2001
Honda that won't start below 50 degrees unless I heat the PCM with a hair dryer. And I can't find and need to buy one off Ebay, along with the PCM the ignition switch and imobilizer all together as a programmed package, no help from Honda. Electronic controls fail (Asian made) no warnings like mechanical which most times
signal warning signs. Agree electric fans are good.

I didn’t miss the point. This thread isn’t about YOUR radiator.

First, you posted that the Contour fans won’t fit a crossflow radiator. Which is completely false, they were literally designed for a crossflow.

Then you asked how they mounted, and said you didn’t see how they would fit your 22” radiator. Well, of course they won’t. They’re for a 26” core, which has been made very clear. Other fans that do fit a 22” radiator were even mentioned, the Taurus and HHR fans.

And now you want to call me names because this thread isn’t about your radiator or what fits your car? I don’t care what fits your car. I never said the Contour fans would fit YOUR car. I just corrected the incorrect bullshit you keep posting about fans you’ve never even used so people than CAN use the Contour fans have factual information.

Well, to be fair, your Honda is 19 years old and practically a “classic” itself. None of these cars went 20 years without replacement parts.

If you don’t want electronics on your Mopar, that’s fine, it’s your car and that’s your prerogative. But that doesn’t mean the digital controllers don’t work, or won’t work better than a thermostatic switch.

Sinse u seem to know everything about every mopar ever made , maybe u can come off ur hi horse long enough to figure out , I was more inquiring to the fit to my radiator , u seem to take about everything the wrong way , wake the f--- up !!
I aint the only one on here that feels this way either!!

Rusty the Taurus fan works well, 2 speed single fan boasts 28000 /4500 CFM. I couldnt keep my 470 cool untill I put it in.
They have become so popular their hard to find in junk yards but only certain yrs. You can research them as I did .

I have the Contour fans on my champion 26" to cool my 340. The dakota dakota controller works sweet. It comes on at a preset temp and turns off at a preset temp and also comes on with the AC clutch kicks on.

All of this is set to your specs on the controller.

uh, think you put an extra zero in there :D

Here's the Contour fans on my 451 (26" rad of unknown origin). It's a tight squeeze (just trim a little of the plastic ribs where the WP pulley spins).
