Hello,
A friend has an intermittent problem with white "smoke" coming out of the dash vents.
The vehicle is a 2004 Saturn Vue and has a V6 engine in it that has had the
100k timing belt service performed at around 115k. As I understand it, there's no correlation to the service and when the problem started occurring. Each time the problem has occurred the vehicle has been taken to the dealer only for the owner to be told that they can't find anything wrong with it. This has happened several times so far.Upon searching for a possible solution, it was mentioned that it might be cracked heater core. That might explain the intermittent nature of the problem. However, I'm being told that the vehicle isn't losing any coolant (Dexcool, I believe). Supposedly, the dealer pressure tested the cooling system and found no problems with it.
Another strange symptom is that recently the low coolant light on the dash comes on, yet the vehicle isn't low on coolant and the dealer says that the vehicle is fine. I was also told that when this just happened the vehicle ran rough.
Any thoughts as to what to look for or what the problem might be? This is becoming very frustrating for the owner, who just wants to get the vehicle fixed.
Thanks in advance to those who post a reply to the group.
Peter.
