Is it possible for the entire cooling system and by entire I mean lower radiator hose temp sensor thermostat and water. I would like to know when u have the car serviced for cooling system flush and routine maintenance done regularly on time to prevent failures, is it possible for all these items to go bad all at the same time with no warning after having it serviced 6 in a half months prior to breakdown had been seeing the blue stuff since it was serviced but was new to bmw's and was unaware that the coolant was blue until now I thought the blue stuff was window washer fluid not antifreeze any way to make a long story short is this in any way possible for the entire system to fail after being properly serviced at bmw service centers not after market but dealer fees for services and is it possible for the dealer servicing to perform a cooling system job within a 30 min time frame after coming off the highway for about two plus hours of driving to get to the service shop no waiting for the temp of the car to cool down or how long do u wait for the car to cool down before changing the boiling hot fluids? Help me please this is crazy !

Yes there is a service interval for changing coolant. It's generally in the 75,000 to 100,000 miles on newer vehicles such as this. If the BMW dealership has a coolant flush machine it could be exchanged in 30 minutes without mechanic having to touch the coolant. Did they change parts and that amount of time as well?

My receipt shows coolant exchange and 2 pk radiator kit I'm not sure what the 2 pk kit is. But the vehicle condition report shows no maintenance interval due and nothing else was reported to be wrong or to needing to be replaced

So is this even possible that the entire cooling system needs replacing all at the same time everything fails 6 months after routine maintenance on the cooling system

Are they telling you that the whole thing needs replacing! If so the I highly doubt that. But if the kit and flush are all you were charged for them id not worry to much. Some coolant system maintenance is to be expected at your mileage

Yes they are telling me the entire system needs replacing is that not what I paid for to avoid happening with the required cooling system maintenance? How does the entire system break down all at the same time

It does all age together, but what parts are included in the whole thing? Is it waterpump, hoses, radiator, thermostat, heater core? Or just hoses and radiator?

Oh ok. That makes lots more sense. Your water pump is probably leaking and its standard procedure to replace the tstat when that happens. I wouldn't be afraid of what they are telling you, as its not unreasonable
