08 avenger temp gauge going high and losing heat, help please!
Hi everyone! I am new to this forum, this is actually my first thread! I purchased an 08 Avenger SE on Halloween of this year. So far, Love it! Can't go wrong with Dodge. I do however hope someone can give me some insight to a problem I'm having. About 3 weeks ago I noticed that whenever I was idling or had the car running in park, my heat would blow kind of cold. Then I noticed that the coolant gauge was running more on the hot side. I checked my anti freeze and it was low so I added some and thought I was good to go. The car was fine, heat stayed warm and the gauge stayed right in the middle. Then all of a sudden I gave it a little gas and the gauge shot up to almost completely hot and my heat went ice cold. The car is running fine other than that and I haven't noticed any other problems. Look forward to your replies and hopefully a solution.
