1998 Chevrolet Blazer cooling system problems

After turning a corner, the vehicle intermittently shut off, causing me to coast through a red light. In doing so, I was struck by an oncoming vehicle. Both vehicles were totaled in the accident. Three people involved in this accident were injured, including myself. In a seperate incident, the radiator blew apart, leaking coolant and transmission fluid. Dealership found vehicle leaking from top of transmission line from radiator.

My 1998 chevrolet blazer has had regular problems with the cooling system not providing heat to the passenger compartment even though the engine is running at proper temp. The heater core is continually clogging up requiring regular trips to the dealer to "flush" the heater core that is plugged. I understand from searching the internet this is due to the dex-cool antifreeze that GM puts in the car and that there are lawsuits against GM regarding this.
