All the water pumps we carry are metal now , even the one from MINI.

Here is a link to the location and what to look for on the older water pumps.

ECSTuning,

I see you provided two part numbers for the R56 thermostat replacement kit: 11537534521KT3 or 11537534521KT4

What is the difference between the two?

 

One is from MINI and one is from another supplier which is OEM MINI. Just back up in-case the Genuine direct one goes on back-order again. Both include the install hardware bolts.

 

Great, thanks for the info! I will be ordering mine very soon.

 

I had an overheating problem.. 85k miles.. i changed the water pump and belt.. Still overheating.. I ordered the thermostat and housing.. I got it and noticed the thermostat was spring loaded OPEN.. i pulled the connector off .. which would have made the Thermo spring open. i filled it again... started it up. and an hour later it warmed up.. which meant i was right. Took it for a drive.. Boiled over again.. let it cool off and added more coolant.. Drove to work today.. boiled over and tank has water in it.. NO oil in water and no water in oil.. this is WEIRD.. anyone got another idea??????

 

Checking in with my 2009 MINI Cooper S - 39,800 miles. Thermostat being replaced at the dealer today and I am out of warranty as of this past July. Replacement should run me around $500. Just had turbo oil line replaced a month ago.

 

2009 Cooper with 58,000 mi checking in. Just had mine replaced today. Also, I had my water pump replaced at 50,500mi.

 

Just finished turbo Oil line two weeks ago, noticed a small puddle of coolant this afternoon on drivers side right below the transmission bell. Ordered Thermostat from Parts.com ~91.00 delivered.

Don't ya just love a project car?? 67k miles, 2007 MCSA

 

Add me to the thermostat housing list, 104,000 miles

 

Did the thermo last weekend. Just over 60,000 miles. ECS hooked me up fast! Ordered on Thursday afternoon and had the part Saturday morning. That worked out very well since that was the only "warm" day we've had in months and Sunday it snowed again. What a ***** of a project. Good luck anyone attempting it!

 

I did mine right at 60k a few months back. It started out with the water pump leaking. Fixed that. Ran for a week, then I started noticing a much larger coolant leak on the opposite side of the car! So I ended up replacing the thermostat/housing. At the time the housing were on backorder so, I had to limp it around and be careful for about a month while I waited. Its been almost 4 months now and everything is peachy.

Interesting thing I found while doing this project, a whole bunch of leaves had built up behind the fender liner by the firewall. Anybody else have this odd build up as well?

 

Oh gosh yup. I purchased mine used from Carmax about a year and a half ago with 74k on it. After I had to car for about 2 days, there was a big puddle of coolant under it... At least MINI did some failure analysis and designed it to leak instead of straight up failing. If that had been my old GM car, it would have just dumped ALL the coolant, necessitating a call to AAA.

 

Yup. 2007 Min Cooper S 82,000 miles Just replaced my thermostat housing and water pump.

 

I want to replace my water pump before it goes bad and even though I have a 6-Year extended powertrain warranty I'm seriously considering paying out of pocket just for piece of mind. It's better than waiting for my water pump to start dumping all my coolant onto the road while I'm driving!

The replacements are all aluminum housing!

 

me, too. replaced housing and pipe. 68,000 mi. I also have to do the Turbo Oil Inlet replacement as well. 2009 JCW.

 

Just replaced my thermostat housing due to a leak. The car has around 60K miles. Weird way of making a thermostat housing. I can't say I am a fan.

 

Remember the wax pellet type thermostat housings, they would open when the wax got hot enough and close when cooled. Those were very simple design, the Mini design is complicated!

 

It's a Mini Cooper base model, 2010, 28k ,Got CEL, then went to read the detail of the code, it's' thermostat temparature below regulating temp'. Searched online and determined to replace thermostat housing. got one from local dealership. Replaced by myself in ~4 hrs. Went to local auto parts store to reset the code. ~300 miles later, today, the CEL comes on with the same error code. Only concern is not able to pass emission test, then not able to register and drive again.
Any suggestions are welcome!

 

Sounds like the coolant temp sensor. make sure the sensor plug is plugs all the way in and not loose. Also make sure you bleed the coolant system and get all the air out, seen those codes thrown when changed and there was still air in the system. See the changing N14 engine thermostat threads.

 

2010 R56 S with 75K miles. Was leaking, no code. All hoses seemed fine and could not see the leak, so figured it was from the t stat housing. Took 3.5 hours out and in taking my time. Then another hour to fill and let it settle. Went well and as stated in the how to thread. Some connectors are difficult to release especially if you cannot see them. Probe under with a pick and you'll get it. I think you do not have to take the wiring harness cover off as I did, as stated by another post it would have been fine to just pull it and the harness straight up off of the t stat housing and you can work underneath it. I think I did not need to unplug the ECU cables. Might have given a bit more room for the wiring harness to move, but might not be necessary. A thin wall 10mm socket is needed, especially for the bottom front t stat housing bolt. Removing the airbox helps to see the clip on the rear hose to the water pump. I used water pump pliers and needle nose vise grips for all the hose clamps. Bought the MINI t stat housing from Turner Motorsports for $100. MINI said they would do it for $500.

 

$500, that's crazy! You can buy a Forge FMIC for that!

 

65000 miles thermostat housing leaking !! I would like to meet the guy that came up with that jewel nothing but fun Changing that thing out. BMW of San Antonio wanted $750 ..

 

BMW of san Antonio wanted $750 ..

 

Now their just plain stealing your money if you take it there. Those service guys get paid on commission hence inflated prices, go somewhere else!

 

Follow the part number above and links on the DIY, if you can do it yourself. If you cant, find a indy good shop and show them the links. Thanks and hope that helps.
