Mine was at the low line so I bought some of the Pentofrost A3 blue from AutoZone and filled it back to the full line. I do smell coolant from the grill when the engine is hot but can't detect any leaks anywhere. Anyone else experience this?
Yes, and I think it's normal. The reservoir isn't pressurized so fluid can boil out and even evaporate over time. At the very top of the reservoir, you'll even find a little breather hole. I sometimes find dried coolant residue around the green fill cap too.
I purchased a gallon of Pentofrost A3 back when I started this thread due to my reservoir level being low. I used the A3 to fill it back up to Full. In the time that has passed since, my reservoir is back to Low again. I think it's normal as I've seen this sort of thing happen on my other cars without pressurized reservoirs.
