Agree, this could be from the thermostat housing. Likely you just need the o-ring/gasket and might as well get a new thermostat while you have it off.

This is not an uncommon failure.

 

Very safe.

 

Absolutely not true in my experience. I had my rad fan fail earlier this summer - would only come on in high speed mode - and the temps would climb slowly from the mid point towards the end point (vertical) - sometimes staying on the 3rd indicator line if I was stuck in traffic, turning on the heater @ max capacity would bring it back to center.

 

Glad to hear the leak was verified to be the Thermostat Housing and that it will be covered under warranty.

 

I agree with all above just make sure the water you add is Distilled Water, you wouldn't want to add all the chemicals into your cooling system that are in either Tap or Well water.
Make a stop before bringing your Mini to the dealer for the coolant flush and pickup a Gallon of Distilled Water for them to use when mixing your coolant. (50/50 mixture).
After working in the dealerships for 20 + years before going into biz for myself I never came accross 1 dealer who had or used Distilled Water like they should have been using.
For under $ 1.00 your coolant system will Thank you for years to come.

 

Where you one use this tool as there is no radiator fill neck in the radiator? I bought the tool and then realized there is no fill point :nonod:

 

I've never used the tool, only heard about it from my mechanic, but I assume you use the radiator overflow tank.

 

Thanks. That's what I've been reading elsewhere, probably gonna try it this weekend.
