How do u disconnect radiator hoses???
I've got a coolant leak, constant drip drip drip falling from the bottom of the engine. I'm assuming its the thermostat housing or w-pump. So, i'm gonna replace both. I've done it on my older bmws in the past but these new style radiator plastic hose clamps have me stumped. I've removed the metal clips but the hoses will not release from the t-stat housing. What is the secret? I don't want to break them. Any help is appreciated.

Better late than never
The hoses, after a decade, may be stuck. Pry GENTLY lest you break the plastic. Apply even pressure on each side of the fitting.
I put silicone grease on the o-rings and fittings before reassembling.
See link for more info.
Replacing the water pump is a good preventative maintenance idea.

OT: Not that unusual
I am not sure what you are amazed about here.
First of all, under the lemon laws, if the car cannot be fixed after X repair attempts (usually three) the buyer has the right to SUE under lemon laws.
In most cases, the dealer will "buy back" the car before suit is filed, or after a suit is filed but long before it goes to trial - and put the buyer in another car, with the manufacturer helping out with the costs involved.
These cars are repaired (yes, Virginia, there is no such thing as an "unrepairable car" - the laws of the universe may be mysterious, but basic mechanics aren't) and then wholesaled at auction.
You thought perhaps they crushed them? That may happen in some instances - for example where a batch of new cars falls off a train or is flooded, but many of the "lemon" cars are resold.
The cars are then bought by used car dealers and sold to the public. In most cases, they are still under warranty, so if the "mysterious" problem reappears, it will get fixed.
This is one reason not to buy cars from a used car dealer and not to buy cars with an unknown provenance. They could be real creampuffs, or they could be buy-backs, rebuilt wrecks, or flood cars - you really have no way of knowing.
The best deals in a used car are from an individual owner who took care of the car and has all service records. Not only will you pay 10-20% less, you get a better car as well.
