Hi all,

I'm still working through the logistics of sticking the xu10j4rs into my cabriolet and I've got four rad cowlings - one for the non aircon xu10j4r from my cab and three (!) standard '6 aircon cowlings.

The bog standard 2.0 cowling only has one central fan, and a much simpler arrangement - 2 wires connected in the multiplug, and another couple of wires leading off to a temp sensor screwed into the rad. Since the '6 radiator has a blanking plug where the sensor would plug into, it looks like it should be quite easy to fit the single fan cowling in place of the twin fans and bitron controller.

I can think of a few advantages to this:
1) Simpler arrangement so much less chance of things going wrong (e.g. failed relays, multiplug corrosion, etc)
2) Better airflow to the rad when the car's moving
3) It'd be a bit lighter

But are there likely to be any big disadvantages, e.g. confusing the ecu because there's no bitron connected, or worse, inadequately cooling the engine when it goes to over 96 degrees?

Excellent, thanks

theres something wrong with your cooling system then, or the fans arent working properly, if theres no ac you only need one (unless its a td)

my 6 temp sits good too now it has an oil cooler
it used to creep up sat in traffic but is under control now

some info about the fan bitron unit pinouts

Bitron Fan Control unit
Pinout 8010 : coolant temperature unit (/)

Pin 1: 809 : slow speed relay control (0v sink) Too 1508 : low speed fan supply relay
Pin 4: B158: Battery 12V F15
Pin 5: 8054 : Compressor cut-off command
Pin 6: 405 : Coolant temperature warning command
Pin 7: 808 : additional heating request
Pin 8: M801: Ground/Earth
Pin 10: 8091 : fast speed relay control (0v sink) Too 1509 : high speed fan supply relay
Pin 11: 8075 : Compressor cut-off relay command (0v sink) Too 8005 : air conditioning compressor relay
Pin 13: 8076 : Force high speed command (fan unit)
Pin 14: 8081 : Air conditioning compressor authorisation request output (BSI)
Pin 15: C022 : Ign 12V F2

1/ ac mod will bring on both fans if tthe system is working ok

2/yes the std fan cowl sits ok without the aircon rad i have mine removed

double check the 3 relays
if you get high speed with one fan only i would say the other fan motor is faulty

nope both work fine, if i bridge the 2 pins you mentioned in the other thread the other fan spins up just fine! (its a brandnew motor..)

Welshpug, in terms of cooling, i have no low temp fan at all atm, so in traffic it goes up to 90+, with the ac button putting one on at high speed it will slowly bring it down to 90 again (and below) but thats been in the months of Oct - Now so coolish weather, hot weather worries me....

Did you mean French military defeats?

my fans still dont work properly at all, resorted to the ac button to override and put the one on high speed which seems to work - very frustrating...
