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 .
was doing fine going down the road then i pegged out overheated and then completley lost power in my car water went everywhere there is a hole right behind the altinator
After filling radiator up with water or antifreeze it leaks out - in spray like way.
coolant leak under thermostat housing at intake manifold
Working on it Trying copper stop leak
Cracked Intake manifold. Removed and replaced
It just started to leak on passenger side alot
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.
Thermostat housing cracked, anti freeze went all over engine. Replaced intake manifold now runs really sluggish has no power and misfires.
Manifold has cracked and currently leaking coolant.
Not fixed, check engine light flashes while driving. Car sputters, loss of power. Ford dealer will not fix.
My 2000 Ford crown vic is spitting anitifreeze all over angie can't find the leak
leaking just under t -stat were plastic part of manifold meets alluminum coolant crossover.
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.
Overheating 1st changed the thermostat now it's smoking from under the hood & antifreeze on the ground. When I push the gas paddle down smoke come out heavy from under the hood.
left front under edge of manifold shoots out water when i hit the gas its right under a sending unit looking kind of thing
crack around the thermostat housing
