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.

1990 Jeep Cherokee Owner Comments

problem #1

Jan 212009

Cherokee 4.0L

  • Automatic transmission
  • 220,000 miles


most of the times my car would always overheat. replaced water pump radiator and overflow tank. turns out the problem is most likely your headgasket is either craked or blow, a big problem with the straight 6 models is because of all the torque the head usually will warp causing the head gasket to go out. head gasket set only cost $75 from autoparts store. a shop would problem charge a couple hundred to replace. it was my first time doing something this big and oly took me about 6 hours of wrenchiing to have it totally fixed and now it runs alot better. no problems wth overheating so far.
