For any car really the temperature of the coolant will dictate if the fan comes on or not. Pretty much any amount of car movement will put enough air through the radiator to keep the coolant from getting too hot, so the fan isn't required.

I'm not sure if there's anything specific about stopping the fan from coming on when moving, I'm pretty sure on a track day when my fan's been on flat out I've driven off and it didn't stop running immediately.

You know I've been driving for 30 years and never realised just always thought it came on as needed. Like you said heard it running when ive gotten out of the car and presumed it was already going. Well you live and learn.

It does indeed come on "as needed" but by definition "as needed" is only likely to be with no air flow under the bonnet when stationary as the temperature rises further.

As said above.

When moving, the cool air over the radiator will be enough to keep the coolant cool. Only when you stop should the coolant get hot enough to need the fan to simulate air flowing over the radiator to cool it down again.

Turn on the aircon and the fan comes on to cool the condenser, which is normally in front of the radiator.

Hi guys back again, right finally got around to testing the fan wire for continuity. Right I'll try and explain what was told to me and i preformed it exactly as told. Remove the 30A fuse test across were the fuse was, I got no reading at all. Put one probe into one of the slots and the other to ground, reading fluctuated and then finally when to 1 and stayed constant. Next change the setting to continuity and put the probe in the other slot and the other in the fan connection, I got no readings again. Again any ideas what i can try next. Thanks

Ok I've got a different question, my pas fan is not there, that in itself is not to much of an issue but i can't even see the electrical connection. So i called a specialist breakers earlier to get a price and he informed me that not all R50's are fitted with them, is this right?

What is that about, so the pump on the R50 doesn't need cooling or is it a case of different pump i.e. a belt driven not electic?

the engine is less stressed, less heat, no need to compensate,

I don't mean to harp on just trying to understand, ok so not all R50's have the pump but all 53's do, but isn't the 53 the same car just convertible? What's the difference in the engine's. Mine is a 1.6 cooper so if mine doesn't have one which one's do?

UK R50s don't have a PAS fan only hot weather countries. All R53/R52 1.6 SC Engines do
R50 1.6 NA Cooper
R52 1.6 NA Cooper convertible and 1.6 SC Cooper S convertible
R53 1.6 SC Cooper S

Valeo as in the SMF conversion? Your call, sounds cheap enough but imo LUK especially if it is or will be modified, there's about 20% less friction surface with the other, whether they work for people or not, that to me is a concern

Bought a 56 plate R50 a few weeks ago, all seemed ok till steam started coming from under the bonnet, soon realised the fan wasn't kicking in. Quick google found out what the problem was and by passed the dreaded resistor, guess what, still no fan. So I just changed the thermostat, absolute nightmare couldn't get the battery tray out(bolt heads had corroded). I put the coolant back in that came out and it was way over the max line, so ran the engine till warm, expecting it to fall once the thermostat opened but no, nothing, so must have an air lock. Opened the bleed screws 1 just off the top hose and another on the heater hose, coolant came out of both straight away, still nothing, still way over the max line. Pumped the top hose a few bubbles appeared in the reservoir but nowhere near what you would expect. And worst of all still no [email protected]#&*"g fan. Can anyone please help I'm at a complete loss.
Thanks
Is your thermostat inserted iin the correct orientation?

Yeah the thermostat is in the correct position. To be honest wven though the fan still doesn't kick in, the steam has stopped and am no longer losing coolant. Do know what i did but it ses to have worked

I actually think it was probably a big air block, because since changing the thermostat and bleeding the system all seems as it should, aside from the fan, but I'll figure it out. Wondering weather its an earthing problem, corroded wires or something similar.
