Leaking coolant on 2007 mini cooper. The dealership wants $445.85 to fix/replace everything. A friend of mine said I should just put something called "Bars Leak" into it to stop the leakage. If I do that, is there a chance of doing more damage to my mini?

Hi, W/D here.

The short answer is "it depends". If the coolant leak is evident (showing), then you should first tighten up the leaking component if such can be done, paying attention to the torque values for the parts. These are obtained from a manual, which is available from an auto parts supply store. Secondly, if the leak is on a part that is easily replaceable, and tightening doesn't remedy the problem (as in a bad radiator hose clamp or similar), replace the defective part. Thirdly, Bars Leak (or similar) is OK to use. Just make sure to read the instructions label to make sure that it will be of value in your type of leak. Some exclusions may apply. Talk with the personnel in the auto parts store about your issue, and they will make recommendations. Lastly, again depending on the leak site, You can perform the work yourself. The above mentioned manual is invaluable in this effort, and provides a wealth of other information as well. I have a manual for every vehicle that I own. They provide everything you need from changing light bulbs to engine rebuilds. The cost is usually in the $20 range. Should you elect to tackle thew repairs yourself, take pictures before you start. Mark and tape the wires removed, and make sketches of what connects where. Evey mechanic that I know does all of the above and it makes re-assembly muuuuuch easier.
Best regards, --W/D--

Why is my coolant reservoir smoking and leaking water

Hi Diane
Most common cause of overheating is a gradual loss of coolant from the thermostat housing seal. You need to top up and bleed the system and arrange to have the thermostat housing checked / replaced.

2007 mini cooper s running hot in traffic

The heater core had air in it and so did the upper hose. I think when they add coolant to our MINI's the system they use pumps air in. They need to bleed it out. Had mine fixed yesterday.

I have 2003 mini cooper s model the rear door light stay on all the time any help how to fix it.

mine too. I've noticed that the rubber seal has worn in that area due to friction. I think it must be a design error. The rubber sticks out too far. When I close my trunk, I always push down in the middle very firmly. That usually does the trick. <!-- from fixya rte -->

I had a reconditioned gear box in my mini cooper

Go to a Mini main dealership with proof that you own the vehicle. Also take along the servicing record. Using the VIN chassis number on the vehicle (and also in the service book) the dealer can look up the radio code for you but they may charge a fee. Most main dealers will give it to you for free if you ask nicely or are having any other work done on the car by them.

I'm puzzled by one thing though: a 2007 Cooper should still have been under the manufacturer's warranty, so a duff gearbox would be replaced by a Mini dealer. Part of the job would be to re-input the radio code. If this is what's happened and they couldn't provide you with the code I'd complain vociferously and get it fixed elsewhere in future.

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.

I just read in the 2009 Consumer Report Best and Worst Cars

The main cooling issue that is for the 05 cooper is the Thermostat gaskets leak. MINI has updated the part but has not issued a bulletin or recall. Check under your car often and make sure there is not a puddle of coolant. They just updated the part within the last 3 months, so it is still pretty new. The old gasket is a white color and the new one is a semi clear. The only thing that you can do is be on the look out for coolant leaking on the floor in the middle or towards the drivers side of the engine bay, Almost positive that MINI will not allow you to replace a part under warranty unless your thermostat is leaking. Hope that helps answer your question
