Why mini cooper 03 overheats while the AC is on?

I have already replaced the thermostat and the engine continues to overheats; It happens when the AC is on and while at idling. No leaks. No head problem. Any idea anyone? Thank you/

Check to see if the electric cooling fans are working. Some of the fans have 2 speeds and some need to operate on high speed constantly when the air is on. High speed could be a burnout.

There should be a temperature sensor, a fan Relay, and then the electric cooling fans.

Testimonial: "Thank you Fordexpert.I think your right. It's a two stage electrofan and the relays are fine. I'm down now to trobleshoot the temperature sensor and electrofan. "

SOURCE: 2005 Mini Cooper Engine Cooling Problems

There is a problem with the thermostat gaskets. Often times they leak and allow cars to overheat. Check under your car and make sure that there is no coolant leaking. MINI has updated the gasket so if you get your car serviced at a mini dealer then your gasket will be updated. There is not a bulletin or recall for this replacement this would be at your cost.

My 2009 mini-cooper heats and loses power when the ac. is on phoenix az

No, there is nothing to change in the programming. Make sure the fan is coming on high when the engine is hot. If not, please get back to us for troubleshooting. If the fan is coming on high, the thermostat might not be opening fully.

Hi the garage has just charged the alternator on our 2004 Mini Cooper as the battery light was coming on. The heater was working fine and blew hot air prior to this. The heater is now blowing only cold air...

Ask garage if they removed and water hoses to swap alternator.Needs proper bleeding after draining. Minis prone to water loss and overheats...dont drive till sorted...got a 59 plate cooper in workshop now...needing full engine due to overheats. Very important to bleed properly and pressure test to ensure no leake ( usually fron thermostat housing.

Dashboard overheat warning light blinks continuously after 5-mi

It is not the thermostat since it only overheat on stop n go situation. Most likely cause is a bad radiator fan. Turn on the AC and see if both the radiator, and the condenser fan works. They should both be working when the AC is turned on. Lets stick to this for now. Let me know what happened. I don't want to confuse you with too many possiblity.
