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.Google+

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.

the coolant intake is plastic broke at thermostate housing.. installed new alluminium intake
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 .
