Coolant Leak and/or Engine Overheating Due to Cracked Intake Manifold on Ford Crown Victoria

The composite (plastic) intake manifold may crack near the thermostat housing and cause a coolant leak. Ford released an updated manifold that was reinforced to prevent a recurrence. No recall was issued for this problem but Ford did extend the warranty to seven years on some models from the date of purchase.

Coolant leak by the coolant crossover
Pol Int -- cracked intake manifold due to ford's bright idea to make money off of plastic intake manifold . Replaced myself with the help of the internet and youtube . Used part $55.00 (junkyard off internet) , gasket set $21.00(kragen/O'reilly), DEALER ONLY-new heater coolant return-line (under intake-manifold metal pipe)$45.00 (also due to fail soon after this manifold issue. BETTER to replace whilst everything is already off , no?) New Dorman replacement is $200-250 for Manifold BUT includes gaskets built in .(Dealer is 234.00) My cost in parts $121.00 with additional installation of Under Intake-Manifold Coolant Return Line .

Just had my car towed in do to this cracking on the interstate. Not a happy camper. Hope this is not to expensive.
on hard acceleration, the heater hose pops off the manifold. The radiator hose, when manually sqeazed, feels like there is no water pressure running through it.

Mine has a crack right behind the alternator and sprays coolant directly into the windings of the alternator. This caused a short over time and my alternator caught on fire...luckily I spotted the problem before my car burnt down and purchased an updated version of the manifold with aluminium coolant crossover. Something ford should have thought about in 1996.
