Dual fan kit

[turbolou]

Anyone know of a source & what the current hot setup would be. Thanks Lou

I have the dual fan kit from Gbody with the caspers plug n play harness. I can idle in traffic down here in Louisiana in the summer time with the A/C on and the temps dont go above 185. And it gets HOTTT down here.

im running the same thing as 87NAT .. works great

+3. I'm running an F-body radiator. Had cooling problems, now I rarely see over 170.

Do you overheat? I run a single fan and don't have any issues. Been in bumper to bumper traffic while it was around 100* and everything was great. Any chance you have a problem somewhere in your cooling system?

I should clarify. I used to have a cooling problem. Part of the solution was the F-body radiator and dual fans. I no longer have the problem and am very pleased with the gbodyparts setup.

I still like taking the dual fan setup from a dodge intrepid. they're cost effective and they work. Plenty of those cars in junkyards today.

Also know of a member who converted his hot air to an electric fan setup by using the single fan from a Lincoln mark VII, I think.

is there a certain year dodge intrepid to look for or will any of them do ?

you would want the dual fan setup from a '98 - '04 dodge intrepid. I believe all three engine options (2.7L, 3.2L, and 3.5L) had the dual fans. Actually any '98 and up Chrysler product will do - intrepid, concorde, LHS, 300M.

this fan style is also called the Ramchargers (RC) fans bought through Ramchargers (hi-perf Mopar stuff) when they were in business, but you can still buy these new from a dealer or used from the junkyard very inexpensively. OEM fans taken from a junkyard car are more reliable than the similar fans sold through ramchargers. there was a discussion a while back about the reliability of the that the dual fans that RC sold were the ones that Chrysler rejected - that these fans failed initial tests and were repaired and sold as "surplus", or "factory seconds" by ramchargers...

Do a search for dual fans in all open forums as there is some great info that does not need to be re-created here. Note that as you read the other threads, this is a topic that will have varying opinions. Most of the differences are in how the two fans are wired for operation (high speed and low speed operation), brackets for mounting the fan (top/bottom mounting or side/side mounting), and the depth of the fans. Some guys need really low profile dual fans while others do not. Some like the Spal fans for this reason. Another thread notes using the dual fans from a '98 Olds cutlass.

Here are a few existing thread with good info....

Dual fan control systems

dual fans squealing...anyone have this happen?

Dual Fan

POST #9 IN...Ramchargers fans not working

Dual Spal Fans

As you can see, there are several threads on this topic. If you go this route, use the Casper's dual relay wiring harness. Junkyard fans from the Chrysler products are about $30 - $40 from you-pull-it type junkyards.

And just to clarify....

the dual fan kit that G-body parts sells is the the Chrysler dual fan setup. You can get the plug and play wiring harness/relays directly from Caspers.

wow those are interesting threads seems like the RC is not the way to go for long term reliability its like a crap shot ............ thanks for the the information

I didn't want to totally push you away from the Chrysler dual fan setup. I haven't had any problems with the ones I've gotten from the junk yards. I test them in my daily driver intrepid. You could buy 2 or 3 good used ones for the price of a new one.

the majority of failures for the Chrysler/ramcharger dual fans is from....
1. using the '97 and earlier OEM assemblies and the factory "seconds" from ramchargers (until ramchargers went out of business a couple of years ago). the dual fan setup was re-designed for the '98 model year.
2. using the turbo regal factory wiring (single low speed relay, which is undersized) instead of the dual relay kit from Caspers.
3. having both fans only run at high speed all the time. these OEM units were not designed for extended daily use only high speed all the time.

I copied this text directly from the Casper's dual fan relay harness installation instructions for the chrysler/dodge/ramchargers... "The relays are both energized by the factory fan relay in the Buick, reducing the circuit load on the factory relay and permitting full coolant fan control without overload risk. The fans are then both powered at high speed when cooling is commanded via factory low speed coolant fan control through the ECM. This system assures proper load through the relays with proper power distribution."

Okay, so the first thread asked about other setups. there is also the GM F-body dual fans as an equal choice. Get them from either GM or the junk yards. The control strategy here is that both fans operate when either low speed cooling or high speed cooling is requested.

So, the F-body dual fans can fail the same way as the chrysler dual fans - neither setup was design to operate both fans only at high speed all the time. So when we use a product outside of its original design, there exists the potential for premature failure. make the choice that is best for you...spend a few hundred bucks on a new fan or 40 for a good used one. either way the casper's wiring harness is still about $70.

good info there I appreciate it. and its always good to know there are options out there.

what about the radiator ? any more options out there besides the f-body or is that the way to go ?

Anthony, excellent reply, right on the money, & thanks to all the rest for the help, I now have the answers I needed. But it has been said that never give a child too many choice's lol Lou

it all depends on whether or not you want the oil and trans cooler built into the endtanks like the factory Buick one had. some choose to run a variety of combinations of internal (to the radiator) and external combinations. it really depends on the engine setup and use (racing only, street only, or some combination of street/strip).

some choose to just re-core their factory radiator when needed.

some choose the F-Body radiator with various combinations of external oil coolers.

some choose an aluminum multi-row core radiator with both built-in oil coolers. check out this earlier thread about aluminum direct replacement radiators...

Well I just ordered the Gbody setup this morning. Oh well I like brand new stuff on the Brick anyway. Jon
