While driving in my 89 Deville, 4.5 liter I began to smell antifreeze in
the car. No signs of smoke or steam, temp lkight did not come on. Not a
big loss of coolant from the coolant reserve tank on the side. Could this
be associated with the heater core. HOw hard is this to fix? Can I use
some stop leak?

You could try some BarsLeaks pellets or Golden Seal but most likely
the core is shot. Usually you remove the two hoses at the firewall and
remove the core by removing the glove compartment and anything else in
the way. Buy the best core you can get or you may be doing the job

constitutional rights it acts lawlessly and the citizen can take matters into
his own hands and proceed on the basis that such a law is no law at all."
