Where is coolant bleeder screw?

I am looking for the bleed screw. I have the '07-'11 Bentley manual but it does not have a picture. The TIS has picture but it's not clear.
I have searched forums but they are mostly 1st gen.

Problem I am having is heater goes cold at each stoplight.

I have '10 Justa Clubman with manual heater controls. Coolant in reservoir is up to max line.
Would like a photo if possible.
Thanks

I have seen that photo in other threads but it does not look anything like what my engine looks like.

OK I found it. It is fairly large cap like thing with a (+) slot for a straight blade screwdriver. Does not even look like a normal screw or bolt head.
The pdf was for N14 engine and I have N12.
Went back to my TIS which is still not accurate because the last model the ebay TIS covers is '08 and I have '10.

It's a large black plastic screw. It blend in well. Straight down from the top between the hoses. Look for a large +.

Don't unscrew too far or it falls out and then can be hard to find.

Near the thermostat? Right side of engine? I have looked around there...do I need to take something apart to see it?

Thanks...

If it is not obvious, the previous owner may have replaced the upper coolant hose with an aftermarket one, e.g. silicone, without the bleeder.

Nope. It is 100% not there. I have a 2011 JCW and it had the thermostat housing replaced in 2011. I am looking at a pic of a thermostat housing online. I see the coolant temp sensor and bleeder screw. On my car I see some kinda of modified temp sensor and exactly where the bleeder screw should be - nothing. Maybe this was a service bulletin or an updated part? Any help would be great because when I refilled the system only took in about 32 ounces of mixture and not a drop more. Ran the car with heat on for a few minutes hoping the thermostat would open and suck it in - nope. Don't want to overheat the car. Any suggestions?

I have what looks sort of like a bleeder screw but it's actually the temp sensor because it has 2 wires coming out of it. Weird.

Ok. The N18 bleed screws are integrated into the temp sensor. Weird turning a plastic bleed screw with temp sensor wires attached to it. Never seen such a thing. By the way I have a 2011 JCW with a N14 engine apparently with an updated t stat housing similar to the N18 engine.

The screw is right above the connector. I have an N18. How can you tell if your have an upgraded T stat?

I have no idea how to determine if one has an updated/upgraded t stat housing.

The MINI stealership looked up the p/n of my t stat housing changed by the previous owner - and when I googled that p/n a picture of the old t stat housing shows up - which does not match what is on my car. There must have been some upgrade or service bulletin done to my car. I finally found the bleed screw so I'm all good.

Might be a dumb question but does the bleeder screw all the way out or is there a stop on it? In other word, can you screw up and screw the screw all the way out until it is completely out or will it stay in the hole?

Don't screw it out all the way.

It will fall and you won't find it. Just loosen and wait tail it starts burping coolant then tighten.

I turned mine out three full turns. Maybe 3 and a half. Fluid came out and I screwed it back in. It doesn't seem to tighten fully and seems to keep going around. Maybe I turned it out too far? and need to thread it properly?

R56 2007 mini S bleeder screw

I recently bled the cooling system on my R56 2007 mini S and had a difficult time locating the bleeder screw. Although there were others who were able to describe its location, there weren't any detailed photos of my model online so I thought I'd post my photos in hopes that it may help someone in the future.

When looking at the driver side of the engine bay, the bleeder screw is in line with the spark plugs (specifically the region to the right of the 4th spark plug), and 3 inches below the plane of the spark plugs (the region will be dark making it difficult to see the already black screw, but it's reachable). 2nd photo shows a magnified shot with a flathead in the slotted bleeder screw for reference.

My 2012 S did not come stock with a bleeder screw. The new thermostat did have one. Surprisingly bleeding the system was very easy, didn't need the screw, I have heat and engine runs at correct temperature. Now changing the thermo, h2o pump and water pipe was not fun. Thanks for the incredible design whoever did that.

Thank you so much; this was very helpful. It only took me 10 seconds to find it thanks to you.

I'm curious, what is the purpose of this screw? It is not referenced in Pelican Parts guide:

Allows you to remove air from the system after replacement of water pump, thermostat housing, coolant, etc...
