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.

Grand Cherokee Laredo 4.7L V8

I actually replaced the heater core 2x. I replaced A/C evaporator core when I had it apart the first time. The whole dash has to come out.

problem #1

Dec 102007

Grand Cherokee Laredo V8

  • Automatic transmission
  • 106,000 miles

Just to let you know, that if you start to smell anti-freeze, and you start to see your windshield fogging up, most likely it is your heater core. Get it checked right away. Please try and find a shop that deals with radiator's; a/c; heater's etc. the dealer wanted 1,700 dollars to do the job. The going rate is 100.00 an hour. the part is about 100.00. It is a big job. They have to take the whole dash off, and somehow disengage the air bag system. If you're not a regular mechanic, forget about it! It is a big job!
