Huge win for car owners! All TSBs to be made public. The Center for Auto Safety just made the NHTSA (US Government) make public the full text of all TSBs from now on. They are the same organization that has petitioned the NHTSA & filed lawsuits to protect car owners over exploding gas tanks & other major safety issues. Whenever you drive in your car, you are safer thanks in part to a lot of work over the years by this small but very effective consumer advocacy group.

Please take a moment & say thank you by donating $5 or whatever you can to the Center for Auto Safety.

I kept smelling antifreeze after driving the van but never could find a leak. Finally, I noticed the engine was overheating. Looking carefully, I discovered a coolant leak at head gasket area. While removing head assembly, I noticed two bolts were loose. After removing head assembly from engine block, I discovered stripped threads in one of the bolt holes to hold the head assembly down. A helicoil insert will be used to repair threads before reassembly.
