1998 Mercury Grand Marquis: engine overheating

Filed Mar 22, 2014 · Engine · 102,281 miles · FL

I observed a coolant leak around the thermostat. I found the plastic intake manifold to be cracked around the thermostat and leaking coolant. I made contact with mercury and found that there had been a recall on the plastic intake manifold in which they would have replaced the part at no charge during the safety recall campaign. I was not made aware of the safety recall and have owned the vehicle since 04/17/02 when I purchased the vehicle used from a mercury dealership. The dealership would no longer honor this recall although there are still thousands upon thousands of these engines still on the road. The all plastic manifold was replaced with an intake manifold with an aluminum crossover channel for the coolant. I was forced to replace this defective part out-of-pocket at a cost of $800. It would have been more had I not been friends with the mechanic. The vehicle had 102,281 miles at the time of the failure.

Faliure has not happened yet but has the potential with all of the other 1998 mercury grand marquis. Plastic intake manifolds are defective from ford and cause coolant loss. This can cause engine damage and possible engine failure. Recall applying to fleet vehicles should apply to private use vehicles as well. Average repair costs between 700-1000 dollars.
