I have had similar problems in the past,it could be the water pump or maybe a bad water hose in that area.Good luck!!!
I started smelling coolant today driving and then I noticed smoke coming from the hood.. I thought maybe it was overheating but temp guage was fine. pulled over and opened the hood I have coolant on top of the intake and splashed around soming form somewhere on motor can't see any hoses etc.. leaking. did not overheat, not coming from radiator. the coolant guage came on so I limped it home with heat on but car ran exactly the same as before the problem, without overheating. when running there is steam or smoke? coming from behind the pulleys I am thinking water pump?? but I am no mechanic. any other ideas or experiences like this.
