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.

Mysterious coolant leak. Reservoir is low and needs refilling often. Mechanic has performed pressure test to no avail. No coolant on ground at any point. No visible signs of leak. This began right after 2nd cracked flywheel was replaced. At the same time a lifter knock began as well. 1st flywheel was replaced at 103K (3K outside of extended warranty). 2nd flywheel replaced at 143K. Van is kept in mint condition, oil changed every 3K w/O fail. Vehicle seems to be in otherwise terrific condition. 1st and only owner. Date referred to is date of 2nd flywheel crack.
