Question about 2000 Buick LeSabre
I smell around the engine compartment when I shut off the car. No leaks that I can see underneath the car or around the engine. No hose leaks either. I know I lost my air conditioning over the summer and that a recharge did not fix it. Heater core possibly?
Do u smell coolant in the car when te doors are closed? if not it is not the heater core, have you had the system pressure tested at a shop? If I had to guess the 2 area's that would cause this are loose radiator hose clamps that just seep, not enough to get to the ground, but enough to smell the coolant, the other a slight leak at the water pump weep hole on the underside of the water pump, this can also be a seep and not reach the ground. Try adding a can of Alumiseal radiator and block sealer, comes in a little aluminum colored tube, about $3 US

Stop leak blocks up the heater core, or at least that is my experience. Once the anti-freeze fumes get into the air filter the smell may linger for days. If the anti-freeze overflow has been opened by anyone to check it, the fumes will get into the air filter and you may very well feel unwell from breathing the fumes for any prolonged period of time when driving.
