Hot start problem - fan not kicking in for long
« on: 17:21, Sun 18 January 2009 »
hi everyone, im having problems with hot starts after a run, after about 15 mins i cant start my R5.

Ive tried today to work out the problem, is it the little sensor that goes into the carb? The terminals look clean and everything seems ok. Sometimes the fan kicks in, sometimes it doesnt, but even when it does after turning the car off, its only for about 20 seconds then it goes off.

cheers
james

if you have your anti-perc fan on yor car still it will be down to this as this usually kicks in to cool the petrol down in the carb

most people disconect it and just live with it like that

but if you want to keep it you could always put it to a switch so you know it has kicked in

and if yours is faulty/broken there is loads on ebay
DONT KNOCK IT TIL YOU TRIED IT!!!!!!!!!

i saw that video, but was it because it didnt cool it down???
most people disconnect it and live with it? do you mean, each time they try to start? i have to have foot to the floor for abotu 10 seconds of turning over before it will start when the fan doesnt work, now im scared about fires! had a fire before in my mini!

They have a nasty habit of jamming up and catching fire. The inlet hole isn't filtered and all sorts can get in there from under the wheel arch. Even more so if you havent got the plastic arch lining fitted.

Trouble is when the fan catchs fire, so does the plastic tubing joined to it, and in there is the fuel pipe.  :lol:

I haven't got one fitted at all, hot starts aren't much of a problem for me. I don't have to crank it over for 10 seconds?  :shock:  If it doesn't fire up the first time it usually does the second time.

hope this helps (think you might have to enlarge it to see the words)

basicly it says the blue line is your anti perc fan and to remove it
firstly disconect the petrol pipe that goes into the carb(the green line/the one that comes out of the perc fan tube/housing
then loosen off the nuts/bolts on the motor next to the headlight and then puul the full unit out and reconect the petrol pipe to the carb and hey presto :lol:

theres a few modified bits

strapped intercooler - suggests its seen more than standard boost

looks like it had a mod to the breather system with that little filter

Hi James,

Funnily enough I'm just in the process of putting my anti perc fan back on and putting the engine back to how it was originally.

Have you taken yours off yet? If not, please could you tell me where the wires from the fan, the sensor under the carb and the sensor that is dangling where the turbo heat shield should be? Also where do the wires from the solenoid valve go?!

I'm having trouble finding this information, haynes manual seems to have it's wires crossed so to speak! The way it shows it doesn't make sense, and it doesn't show the turbo heat shield sensor or the solenoid valve.

 :shock:  :?:  :?

Thanks a lot that would be a great help!

Love your mini by the way. I had a Mini with 1380cc semi race spec engine and loved it but always wanted a turbocharged one. I bought the turbo bits but that was as far as I got, what's yours like to drive?
