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.

Read a lot of information about this plastic manifold and gasket reacting to dexcool coolant on this 3.8 series II, was redesigned for series III. The replacement part is not plastic!

LeSabre 3.8L

  • Automatic transmission
  • 91,000 miles

I was loosing coolant so I looked on msn.com under autos and checked their reliability info:

Common problems on this vehicle are the failure of the Upper Intake Manifold and Gaskets and Oil Pan Gasket. The cost to repair the Intake Manifold and Gaskets is estimated at $421.00 for parts and $247.00 for labor. The cost to repair the Oil Pan Gasket is estimated at $46.00 for parts and $117.00 for labor. All prices are estimates based on $65.00 per flat rate hour and do not include diagnostic time or any applicable sales tax.

The problem was they used a plastic intake manifold and it would crack causing the fluid to leak into the manifold valley. If you let this go you will Hydro-lock your engine.

THIS APPEARS TO BE A COMMON PROBLEM ON THE 3.8L for several years.
