Hey everyone,
My name's Mike, and I picked up a free 2006 Grand Prix (base) two weeks ago. The cars in great shape. Previous owner didn't want to deal with it anymore due to a coolant leak/overheating issue. So she decided to give it to our family. (I live with my girlfriend Julie, and her family). It was great timing too! Julie's parents were talking about forking out 6000-8000 for a newer car because we all have super busy schedules and are always trying to share cars.
I'm the home mechanic in the family so of course it was on me to find the leak. Literally my 1st Google result after searching "06 grand prix 3.8 coolant leak" taught me all I needed to know about the plastic heater elbows. So for $25 I got the aluminum dorman elbows and replacement AcDelco o-rings, as I heard bad stories about the Dorman o-rings. Car is running now with no leaks. I'm super pleased.
Next on the list is to flush the system of the tap water, replace with conventional coolant, and replace the torque strut mounts, as I can literally rock the engine forward and back by hand due to worn mounts. I will be referring back to this forum in case I need some help figuring anything out with this car.
I will attach photos of it being trailered home, haven't taken any others yet.
Also pictured: My 1990 GMC K2500, we call her The Black Pearl. She did a great job bringing the car home.
