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

Problem Description and Possible Solution

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.

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 .
Cracked Intake manifold. Removed and replaced
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.
I seen car leaking when i checked to see what it was it was water and when I went to lool in reservoir there was nothing there so I put coolant in and when I drove again and popped the hood to check there was coolant leak close to my thermostat
