New MINI R55/R56 coolant leak- resolved


Recommended Posts

NAM forum didn't help. Trying the true gurus here.

Our 2008 Cooper S Clubman has started to mark it's territory. 2000 miles outside of the 36k warranty, I noticed a 10" spot on the driveway. Turns out to be coolant. It is collecting at the front of the motor, on top of the oil pan ledge (which is why I first thought oil), and drips down on top of the exhaust down pipe at the flex union.

I pulled the heat sheild for the turbo to get a better look, but everything I could reach or touch was dry. The hoses and expansion tank bottom were all dry. I can't see the source of the leak. I suspect somewhere on the block/head, behind the turbo?

Any MINI types out there? Any source for troubleshooting info? The Real OEM site helps a little. Bentley says they "are working on" the R55/R56 manual.

The NAM forum said it:

>May be a leaking thermostat/housing. (I thought that was on the right side of the motor. This leak appears to be nearer the front left corner)

>Should be covered under warranty. (We're at almost 39k. Warranty ended at 36k.)

The NAM forum seems to be hit or miss when it comes to technical questions.

I will hand one tip to the NAM board. On another post someone said to determine if the driveway spot is oil or coolant, spray some water on it. Water beads = oil, no beads = coolant. Nice simple tip that makes me think, "well, duh. You should remember to do that Steve".

Just got the MINI back from the dealer.

We all thought it was a coolant line to the turbo, one of the banjo fittings. Once they got into it, they found the oil filter housing gasket was leaking coolant and a little oil as well. Replaced gasket kit 11 42 7 557 009 under warranty.
