The class covers three different groups of GM vehicles which suffered from engine damage caused by the use of Dexcool engine coolant.  Repairs involving intake manifold gasket failures, engine coolant sealing issues, and sludge (a rust-like material) are covered by this proposed settlement. These repairs would likely involve parts like the intake manifold and/or manifold gaskets, throttle body gaskets, radiator cap, heater core, water pump and other parts of the cooling system.
