Hello I'm very new to this but have a coolant leak in my 07 MC S. From most of the forums it appears that it is the thermostat housing gasket. Has anyone replaced this on the 07? I can only find threads for 02-06 and wish to do this myself as the vehicle is out of warranty.

 

Looks like I'm going to have to do this repair on the 06 JCW. Have been notcing intermittent small puddles of coolant under the car. Also heard "liquid sloshing" sound when I started it up this morning: a definite sign of lowish coolant level.

A job for next weekend

 

Thanks for the great write up. I finished this on my 2005 MCS in about 2 hours total.

Like some others, I did NOT drain the coolant and I did NOT even remove a single hose. There was enough play with the hoses still connected to the housing to be able to remove the old stat & gasket and replace them with the new ones, and I barely lost any coolant in the process. No more leak!

Thanks go out also to Way for the quick shipping!

 

I would recommend that you have a magnetic sockets set to use on the thermostat housing bolts. Makes taking off and re-installing a lot less of head ache. At least for me.

 

I'm new to the shade tree mechanic game and need a little help. I have an '08 Clubman S and need to change the thermostat housing. Do I need to put my car on ramps or jack it up? Pardon my ignorance but I don't have the repair manual and I'm trying to do this repair in the most cost effective way. I have the new housing but now I don't know what to do. I'm not super inclined as a mechanic but I'm patient and take great direction.

 

Hi I am not familiar with the Gen2 engine but there is not need to lift the car in any way for the Gen1 engine.

I would recommend that you get a service manual and identify where it is located as well as the steps for removal and replacement.

Do you have a coolant leak or is you T-stat not function correctly.

Keep in mind this thread is the Gen 1 form you might want to look in the Gen2 form to see if more specific information is available there. As i understand all 08s have the gen2 engine

 

@sidewalksam. thanks for the quick reply! I'm going to get a manual today. I was trying to stay on the cheapest side of this repair as possible but I don't think I can skate away without getting a manual. I looked on the second gen. forum and didn't find any detailed diy instructions. I think the newer owners are just taking them to the shop which I would like to avoid.

 

There's a thread on here by Boosted Mini called HOW TO: R56 - Thermostat Housing + Thermostat

I'll try to post a link...

Hope it works ok. Good luck!

 

Thank you soooo much! I think this will work. Does anyone know what the torq specs are if any? Again I'm just a beginner at this:-)

 

These days I generally use the German equivalent of 'gutentight' unless dealing with internal engine parts.

 

It's on the 1st page, 9 ft/lbs

 

Thanks Viper and Eric! I'm going outside to tool around with her now:-) Everyone that has replied to my postings thank you, thank you, thank you! I'll let you know tomorrow how I faired.

 

On an iron block this is really not an issue; however, if you ever have chance to work on an engine with an Aluminum block and you are using steel bolts you would be wise to rethink this.

 

It's worked for me for 35+ years. Hondas, Miatas, and many others. YMMV, and I did snap a water pump bolt on a '72 Datsun - which gave me my first and last lesson on 'how tight is too tight.'

 

I just finished installing my new thermostat. Thanks for the help. I didn't have to remove any of the coolant hoses. Dealership wanted $400. Haha.

I did it on my 08. it was a pain in the butt. I saved a boat load of moolah though. when I get home tonight I will post a link for you. do you mind posting a pic of your engine compartment. I just want to make sure it's the same as mine.

 

my mini '03 overheating when i opened the coolant reservoir there was a mix of oil and coolant any ideas?

 

A blown head gasket most likely. A cracked head maybe. Did a stuck thermostat cause the overheating or are there other issues?

 

Just wanted to say thanks for all this info. I used it to replace Tstat on 03 cooper (non S). Only removed air box/hoses and disconnected pos.battery cable and pulled to the side, disconnected bottom of Tstat housing hose. Unbolted old housing, removed Tstat and gasket, then in new one/gasket. There was a lot of air bubbles when I refilled with fluid so knowing where the bleeders were was helpful. I thought I bleed it properly, but when I went for a short drive the temp spiked for 2sec so I came right home and bleed some more. Think I'll keep checking it for a few days... Thanks again!

 

A big thanks to the OP for the time & effort, and to the other posters for the additional tips. Just completed the job on my '06 which has been dribbling for the past 7 months or so... Tight access, of course, but not a bad job overall. Like others, was able to skip a few steps but it was definitely made much easier by having these detailed & well photographed instructions.

As Steverino said,

Hopefully it will be drip free and I saved $300. That said, my god $60 for the stat and gasket only-from the dealer. The mafia would be proud.

Is there anyone that has the skills/tools to do this at a reasonable cost in the Seattle Tacoma area?

 

You can try minirepairshops.com , there used to be a good site for all MINI shops and the link is broke.
