    Hey guys,

    About mid 30's here today

    Drove into work and when I got there I noticed that there was some slight smoke wafting out from the windshield side of the bonnet. Nothing outrageous, just noticed it.

    I don't have much of a sense of smell left after quitting smoking so I really could not pick much up, I *thought* I smelled a sorta burnt anti-freeze smell

    Came back out at lunch and ran some errands and picked up some lunch. Car was running fine. When I got back I noticed a wet spot in the parking spot I was in. I checked and while I really could not smell anything it felt a little oily but definitely water based. I am not certain the wet spot was already there when I got in first thing but I am pretty sure it wasn't.

    Came out after work, started up just fine. Drive home no problem. It seems that I was not getting that much heat out of the vents. My MINI has never been a high heat or cooling producer but this seemed on the cool side although there was some heat coming out.

    Car has 68K miles

    Thoughts?

    Did you check the coolant level?

    Time to check the coolant level and stick the old head under the engine/tranny and look for "stuff" dripping.

    If it was an '06 I'd say check the thermostat housing.

    You need the 2nd Gen owners to chime in here with their (if any) coolant issues.

    Let us know what you find.

    There haven't really been any water leakage issues with the 2nd gen cars, so I'd definitely check for a leak somewhere....and top it off before you blow the headgasket.

    Ok, car cooled down

    Checked coolant tank and there was about 1/4 in in bottom. Checked all seals of hoses into/out of tank and appear tight and dry. Top off tank with tap water? Go get some anti-freeze?

    Looked around with flash light and saw a couple drips on garage floor, seemed similar to liquid spotted at work

    Also noticed on the following pictures

    Driver side of car, front right tire, notice to rear/right side of tire

    Closer

    Closer still, notice the liquid?

    This is located just below the what I believe is the transmission.

    Think I need to call the MINI dealer in the morning

    Tim,

    I had the heat exchanger go out on mine which was causing a coolant leak. It was very hard to detect as the coolant was dripping onto the exhaust and would evaporate instead of hitting the ground. Granted, the location of the liquid you've identified looks like it would be from something else.

    fwiw, the coolant liquid itself did not seem to have any odor to me either (I'm used to the syrup smell) and really was borderline colorless on the few occasions when it managed to drip to the ground.

    If the overflow tank is low, you've definitely lost some (but that could be normal). I don't think it should be as low as what you describe.

    If you need to top off the coolant (and I'm assuming you don't have a bottle of the stuff from the MINI dealer laying around), you should be safe using coolant that is free of all additives (phosphates, nitrates, etc.). Look for something safe for aluminum radiators. I've read several people say Zerex G5 is good if you can find it, but you may have to use another brand. From what I found in my research, the color does not matter - it is just some coloring and doesn't really mean anything (there is no industry standard or requirements about color).

    Keep us posted!

    Is it true that R56s have two thermostats?

    I talked to the tech and the answer is yes and no

    there is a electrical and mechanical thermostat that is contained in one unit.

    On my 07 they had to replace the entire assembly. By the way the SM responded some later R56's might have the ability to change out either the electrical or mechanical. I dind't dig into it further than that

    Augie is back to his rascally self and I think kicking out even more heat to boot!

    Cool. Thanks for asking. I was wondering how they tackled replacing the two units, but that makes sense.

    Glad everything got sorted out and fixed!

    It's a two-stage unit. It allows different flow levels depending on various factors. Normal setting is for it to have the temp at 220. But, if it's a very hot day, or you're pushing the car pretty hard (say a track day) or you turn on "Max A/C" it will kick in the second stage and drop the temp down to about 180.

    #4 is the thermostat assy, I'll bet it's an expensive bugger to replace out of warranty!

    My understanding is that the engine normally runs at 220* or so, unless it's really hot and/or the car is under heavy load, when the second portion of the thermostat opens sending the temps down to around 185-190*

    I had them do that, replace a bushing on the front swaybar and adjust the sun roof-$300 inc labor

    I'll pull up the part cost from the receipt which is sitting in the car
