i have no heat at all.i know the cooling system needs flushed,there is a bunch of old barrsleak or something throughout the system.but it has been my experence that even if heater core is clogged you will still get a little heat.on this car there is absolutely no difference between outside air temp & heat temp.garage i bought it from replaced raditor dont know why they diddnt flush system then. is there something to use to get the cooling system clean that will work

Detach the heater hoses at the water pump, and force water through it both ways with a garden hose. Try to limit the pressure applied to the system, to prevent overpressuring the core.
