1996 Mercury Grand Marquis, which has a plastic intake manifold, started leaking coolant over the front of the engine. Plastic cracked in front section allowing coolant loss to spray all over. Visited local dealer, palm beach Lincoln-Mercury who admitted this is a common problem and is recalled on some newer models but there is not recall, free or paid replacement on this item. Repairs cost in excess of $800 to have the intake manifold replaced. Please commence investigation as there are numerous other complaints on NHTSA site for same item.
