Was the fan motor seized before you fitted it?

Motor seized would blow fuse, so that needs to be sorted before you try it again.

You will need a new squib for your airbag, you should not have cut the wires.

Does the eps light come on when the ignition is at pos 1?

HOURS of work, Fan Issue Overheating

Thanks, the Radfan was siezed and the 30 amp fuse blown...
This was how it was when I bought the car...
The PAs is not an Issue Now..

My Concern now is making this fan to work as it should
I know the fan works as I tested it b4 i fitted it...
So, I need to solve this and am going down now to fit a
Couple of Earths, 1 from engine to chassis and 1 from
radfan to chassis, and also check the connection is good from old black multiplug onto radfan, it clicks in,but since the fan i have fitted is from a mark1 Siecento and mine is a mark 2 it could be it is not a good connection...
Also I am going to Bleed the System fully from both bleed screws after fittin my new punto 87 degree thermostat I have just bought from fiat..
I will also be checking connections and wires..
I have learned that,like fords,fiats' wires can rot from the insdie out, so it may not be obvious when a wire is Duff...
So a good thing to check when issues crop~up and cannopt be easily sorted...

Radiator Fan Problem

Hello,
Quick Update, got the MOT today
But had to fit a switch for the fan and situated it in the
Ashtray first thing this morn b4 i went to the Garage...

Now I need to fix this Issue ~

The Radfan does NOT Come on as it should ie when the engine gets
HOT... I have fitted a new thermostat from Fiat (87 deg panda one)

So any suggestions as to why it will not come on would be Gratefully
Recieved... BTW the engine is a 1.1 MPI and the plate is 2001
I would like to know if I am right in assuming these only have one
switch/sensor in the water, ie the one that is called the fanswitch
and on mine i think it is situated behind the thermostat, about 7 inch...
So, do I just have one,as opposed to what i think the spi had,namely two ?
I cannot see any other wires going to the rad at all, so i do not think
there is one in the rad...

THANKS
Paul

green one in the heater outlet of the black plastic manifold only

Kristian

Thankyou Kristian...
Hmmm... I think this is what I need to replace then
Paul

You have replaced the fuse, but have you checked the relay (near to the ecu), there is one dedicated to the fan. Mauve/purple ish and grey/balc large wires going into it

Mate, that is my next port of call then
Thankyou.. ~Are they next to the Fuses
I will have to get that replaced then...
If I bridge the fanswitch turn ign on
AND it still aint coming on, then
its got to be Wiring OR Relay
THANKYOU

They should be on the passenger side in the engine bay near the ECU at the rear.

There will be two relays as far as i remember. REmove one and the car won't start, the other is then the fan relay.

edit- you can't just bridge the temperature sensor though, it a a resistive element, and not just a switch, so it won't like thast method of testing.

Oh okay I think I have seen this when I was checking Fuses would it be next to three fuses (high~rating) and under a
plastic cover with 2x10mm nuts ontop

Thankyou for the heads~up on the bridging~issue... I thought it was a fanswitch, but it is not then it is
a temp~switch that tells the ECU the temp, which then makes a decision as
to when to start the fan :idea:
So, perhaps it would be a good idea to
replace the Relay and then see if it is
Cool (no pun intended) with that, ie working normally, if not then maybe replace the temp~switch ?
You really have been helpful mate
Thanks
Paul

You could always test the relay, and test the power supply while your at it, rather than just replace it.

Great Idea
This is Very Appealing since I am SKINT
Having Spent FAR too much on my Car
But on the bright side I have learned a lot and discovered that in the Fiat Scene there are as friendly helpful People as
in the Ford Scene where I am Active
So a BIG To Kristian and SPD

TOP~ADVICE
Thankyou...

ps I recently bought a lil electric~screwdriver . . . . . .
When I put it on a connection it lights~up n stuff So I think I can know if this relay is getting power, and I think by putting it on the power out metal tab (by leaving a bit sticking out) i could see if it is givingpower out...
OH, hang on... if I remove it,and out a live to the correct terminal,then it should put power out, so I can test that :idea:..
And then I can test if live is getting to it :idea:
Since I cannot bridge a fanswitch, how do i test it Should I get the engine hot first, switch it off, get my "stall" together, and test ?
Would it not be easier to try and test the temp switch, or do you think it would be the relay rather, sorry to be so active about this, you have all been GREAT

Take the relay out, apply a 12V, you could even use a 9V cell, circuit across the switching side. You should hear and feel it 'click', and click back again with the power removed.

You can then use a meter across the power terminals to make sure resistence goes to zero when the relay is switched on.

Cheers

HOURS of work, Fan n PAS Issue

Thanks SPD... I do not fully know what to do, but I will
find the one and remove it and try and get it to Click
if it does I take it is working and does not need
replacing... If this is the case and the radfan is
still not coming on as it should then i should prolly replace
the temp switch which i have sourced at 15 del
Thanks

A relay is an electric switch.

it uses a small amount of current to operate a solenoid to switch a larger current, thereby keeping the larger current away from, in this case, the ecu.

By putting 12V across the switching terminals, it should click.

At that point the infinite resistance across the other two connections will go to zero.

So set your meter to Ohms and watch what happens.

Cheers

Hey there,
I'm so sorry to be a pain I don't have a meter, so thats not an option, nor am i getting one (atmo) But I do have a elec screwdriver
Now I have located the two relays, when i remove one the car does not start, so i know which one is the radfan one....
When you say across the terminals ~ what do you mean ? I took it to my jumpstarter pack, did my usual test with a bulb to see i had power, placed the live on one term, and the earth on the other ~ nothing, I tried to get it to click... But it wouldnt, I was unsure what I should put where... I knew the large terms were prolly the ones....
If I could simply establish if it is done or not that would be Great

HOURS of work, Fan Issue

Hello,
I have just spoke to George th owner of the Fiat Garage, and
he says to swop them over, if the engine still starts then the
relay is fine Why did I not think of that :bang::bang:
A new Temp Sensor is £50
So I have foned jiminwatford from here who was VERY HELPFUL
in sending me a replacement PAS Motor and a radfan...
He is going to try and help..
So, I am going down shortly to see if the relay is working
and to weld a wheel~arch lip onto a Volvo
Paul

get one from a scrapyard for about £1 lol.

I've given a few away in my time.

Also, buy a multimeter, will make diagnosis SO much easier. You can buy one from maplin for about a fiver, so no excuse really

Hi Kritip I am geting a 2nd hand one (as above twice:bang
You and SPD have been Absolutley Great
Thankyou....
As for the Multimeter, I think I will have to, I have been
eyeing one where I bought the elec s/driver from...
As for a fiver, I will have to find this "maplins" never heard of them..
And as for Scrapyard, where I live there is not one
Paul
