cooling system problems

Hi all

I am helping a friend who doesn't know what end of the spanner to hold with his mini. He has a 2002 mini cooper s and it started to overheat. When he got me to look at it there was no coolant in it, I started to look why and popped out the thermostat, which was stuck shut. I changed that and filled it back up but it seems like there is an air lock left in it. The coolant is circulating round the engine you can see the colour change with the anti freeze but the fan wont kick in and then it boils over. All the time the temperature guage only gets to half way and stays there no matter if the engine boils over. Is it likely to be an air lock that I have not shifted or something like the temperature sender not telling the fan to switch on? Any help is much appreciated

Thank you in advance


Gareth

Hi ya

The gauge is for show only do not trust it, ideally you need a scan gauge of diagnostic tool to keep an eye on the coolant temp.
You can access it though the IKE this link will help you look at fig 36 select it to test 7 and you can keep an eye on it

You must bleed the system correctly this link will help you :-)

You must use the correct coolant to halfords sell it

Halfords | Comma G48 Antifreeze and Coolant Conc 2L

Check all your fuses and relays for the fans in the engine bay fuse box.
If the car has A/c run the car turn it on the second stage fan should cut in after a bit then turn off and back on. If this works your first stage fan resistor has most probably gone

This link will help post no 8

Hope this helps just take your time don't rush bleeding the system

Hi marque

Thanks for the quick reply

When the car is idling it would not overheat as long as the air con was on but even then the fan was not spinning. As soon as the air con is switched off the engine boils the coolant. Do you think the fan resistor is shot not switching the fan on? Is there a best way of testing it?

The mini has two stages of fan.
Low speed cuts in at 105 deg c and second cuts in at 112 deg c
This is why it's important you have the correct coolant
And you must bleed it properly or it will keep over heating

As said before read post 8 it tells you how to check the resistor

http://www.mini2.com/forum/general-d...t-problem.html

Also make shore the supercharger belt is ok as this belt runs the supercharger and the water pump is run from the supercharger

If you look at the picture attached you will see he has used an Alan key
To lock the tensioner stop, so you see two holes Alan key in one other one free
When that top hole is no longer visible you need the belt changed.
