I have had overheating issues on my Bee !
The issue is the Dual Fans....or rather lack of them !!
And in the summer heat of Spain, that's not good.
Below are some pics of the "shot" wiring.... The squeamish, look away !

What I need desperately is a new "wiring harness" with connectors !
...and any instructions or tips to fit them !
Fiat in Spain are....well, aren't very good, is a good way of putting it, so I need help and advice.

...I'll also add (and people may debate this) I believe the cause is that before I took charge of my Bee, she was running without a Heat Shield (manifold) and this is the result !

"Squeamish look away" is like saying, "Don't look now but..." That's not enough warning! I've had to have a lie down! I hope someone here will be able to help. I've just checked ours but it has a single fan. The wiring is connected to the fan and then clipped along the top of the rad to the connector you show and it then disappears behind the headlight unit and my head is too big (careful) to fit in there. Good luck.

Ouch ! Yep new loom required I would have to agree

Sorry not been on here for a while.

www.barchettaparts.com will probably have all the second hand parts you require. Not really cheap though..... I think the last time I asked he wanted 100 euro for the complete dual fan setup. (which I believe included fans, frame and harness.

Looking on eper harness only is going to be a similar price....

There are several Barchettas being broken for parts in the UK check on www.ebay.co.uk search for "fiat barchetta breaking" you could try emailing them and see if they have the parts you require. If there is any problems shipping to spain I'm sure someone on here could help you out.

www.ebay.de is normally a good source for cheap parts.

Hope you find what you need

This one even looks like it has a hard top fitted..... could be a good score for someone

Hey there Wayne.

I was just reading one of your posts regarding dual fans and resistors....and then you reply !

Great minds, in hot countries, think alike !

And thanks for the heads up on the car being broken.
going to check it's a dual fan car, then I should be able to sort this problem out.

How did you get on with the dual fan question ? What would bypassing the resistor do to the engine ?

I know Doc Orange Peel replied and he's running dual fans (without aircon) and must have some clever wiring going on.
My car has aircon, but whilst it gets hot here....it never get "sooo" hot, so I can do without aircon....and would prefer to have that extra cooling effect when sat in traffic.

Kim

PS. Looking at the resistor and cables on eper, it looks like I only need those parts...rather than the "whole" dual fan system. Would you think I am right in that assumption ?

Kim

Hi Kim.

Looking at your pic it looks like the resistor has already been removed?

I believe that removing it would allow the aircon fan remain at full speed all of the time. The aircon fan is smaller than the main fan so I don't think the extra current would damage anything.

I decided to replace mine with a used one from barchettaparts. Car was fine after this. even in the summer with the aircon on

Have you checked your fans to make sure that they are OK? If they work and the wireing from them is undamaged then a loom and resistor is probably all you need.

Eper shows the cost of the loom to be about £76 and resistor £15. check with your local fiat dealer to see if they are available and get current price.
I'm a bit of a cheapskate. I'd probably buy the used assy and have a pair of spare fans

My current car used to suffer with overheating problems. I've finally seemed to sort her out by replacing the radiator, fixing some minor leaks and ditching the antifreeze and replacing it with water wetter and distilled water.

Probably not recomended for UK based cars but not much chance of it freezing here. Providing the temps in Spain doo not drop below freezing in the winter I would highly recomend it.

Good luck

I may follow your lead with regard the "antifreeze". I have never seen snow here...not even a "light frost". Winters a considered very mild indeed.

As for the resistor, yep there's on there. Just a "spring/coil" inside.
And the mangle of wires clinging onto it.

The wires below look pretty shot up to. When I activate the aircon, no fans come on, so I guess that confirms the "shot" wiring !

I don't fully understand what the resistor is for ! I checked the dual fan set up on eper....and the single fan set up also...and noted that there is no resistor on the single fan set up, so I can only assume that it is soley for the aircon as it's only on the dual fans.

I mainly (pretty much year round) drive with the hood down and only use the hood when parked up (to protect the interior from the sun) or if it started to rain....so would really like the car to run as a "dual fan" car that gets extra cooling... rather than "with aircon".

Just trying to figure out how to do that (and what harm I may do, if any), then I will see if a "vehicle electrics mechanic" can make up a loom for me, using the reclaimed connectors. Surely that should be possible ?

I have looked on eper for the resistor and was quoted 45 euros form Fiat (but they haven't got any in !) and noted that it is the same part number for a number of other Fiats (Bravo, Stylo, Punto etc).

What to do !

Kim

I think I had the same problem that parts were unavailable. I bought 1 from barchettaparts.com for about 10 euro. If yours is still there and intact there's probably no need to replace it. Do a resistance check to make sure it works. Not sure what resistance it should be but providing it's not an open circuit it should be fine.

Check the fans to make sure they work. If you unplug them from the loom put 12V directly to them to make sure they are ok.

first fan should come on just after you start the engine. I believe 2nd fan comes on with air con switched on?

do you have the service manuals? I think they are still available for download from this site. If not send me a pm with your address and I will post them to you on CD.

Hi, I fitted dual fans on mine, I have no air con so just wired the fans to work simultanesly together. Cant remember how , but may be back in my thread i may have wrote about it. Will need to have a search through.

Hi there.

Yeah read through your thread as I realised that you had put dual fans on yours, but you didn't say "how" !

It was one of your early modifications.

And I would interested in how you approached it and achieved it.

I saved the picture of your fans and they look stock ones, so therefore would have had a "resistor hole" there (did it have a "spring" in ? Or is that part of the resistor itself ?)

How do your fans operate now ? When do the operate (in dual mode) ?

I have removed the "harness" (and what a botch the previous owner made of it) and would like to rewire it so that the fans both kick in at the same time.

As I see it the Temp sensor sends info to the Electronic Fuel Injection / Ignition Control unit...and that switches on and off the fan.
In the Bulkhead I have relays for AirCon (5) Rad fan 1st speed (6) Rad fan 2nd speed (7)

AND I am guessing that the "second fan" is just for "AirCon", which I would do without....but would like to use the "second fan" along with the "first" one ! (and not with the Air Con)

Sooo... is there a way of doing this...or is it best to just go ahead with the "normal" fix, which is remake a "harness" ( ask an auto electrician), buy a resistor, plug everything back in ....and only use the "second" fan when (whenever that is !) I use the AirCon ?

A long question I know.... but all are damn good on here, someone will have the answer.

What is it with Barchetta owners ! They buy cars that have passion.
A rare breed we are indeed.

Kim

Hi Kim,

I cant remember exactly how they are wired, But yes your correct in saying one fan is used for the air con and one for cooling.

I would have just conected / bridged the wires until they both worked in sinc,

I dont think it was anything difficult but when i,m next by my B, I will have a look.

I store her at my parents house where its more safe and so next time i,m there i,ll check and post some pics for you.

More then likely to be next week or possibly this weekend.

Hope this helps..

KC

Cheers KC. That would be of great help.

Kim.

Hi Kim, I had a look at the B, and it looks like I just wired the two fan in sync, I must have have found the live going to one fan and then joined the other until they both work. I do have the two cables and connectors intact to those that you show burned in yr pics. So i guess that thats the main connection that allows them to work. Photos wouldnt reveal much as i have my new induction covering the area.

hope you manage to sort them out.

Hey there KC3 and Desert Rat.

All done now...and back in the road. Thanks for all the help.
New fan cable harness, thermostat, water pump (and cam belt, well why wouldn't you !) and a manifold heat shield.

Temp gauge hits the mid way point....and holds firm there.
Even in 34 degree heat and climbing up a 1500 feet hill from the coast...
...and then 2nd gear through a village.

The fans now work, but still want to look at a modified one.
Looked at a Kenlowe on with a manual over ride (kenlowe.com), but the distance from the radiator to the heat shield did not seem big enough.
I needed 74mm (fan and housing) plus 10mm (clearance).
Although I will re measure this now... I now have the heat shield on !
