I have a 1990 Buick wagon with smoke coming in the vents after the car heats up. I suppose it is the heater core. I don't want to spend big bucks getting it fixed at a garage.
Which is better -- adding leak repair or connecting inflow and outflow hoses to bypass core?
If I decide to fix this does anyone know how big a job it is on this model? Is it hard to get to and replace?
Thanks,
