Now I need a new heater core, coolant smell coming out of the heater vent. I'll never buy GM again.
Like many others on this forum, I've been hearing water sloshing around in the dashboard for some time, now there is a coolant smell coming out of the heater vent. Took it in to the dealer, it will cost 1000 to replace the heater core. This, after many other thousands of dollars in other repairs. Looking for another car, it won't be GM.
