The 1996-2001 Mercury Grand Marquis with a 100% plastic intake manifold is known for engine overheating, even with normal use, and a coolant leak from the front of the manifold. This will often trigger the check engine light and low engine coolant warning light. The engine coolant leak is from a factory defect, which causes cracking on the front coolant passage of the intake manifold. In a very short time, this leak will lead to engine overheating issues, especially while the vehicle is idling. This is exactly what happened. I think the car part should have been replaced by Ford when they new about the plastic intake manifold.
Leaking coolant from the plastic intake manifold. Ford want's $500. 00+ for a new one. I can get one from ebay for $150. 00.
