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.

    Just got this same problem, coolant leaking by thermostat housing and manifold. Engine turned off while going down road, never realized coolant leaked out, luckily I was able to turn on a side street and stop the beast. Now I'm off to find the best price on a replacement for this inferior plastic manifold. If I only knew about the 2002's :-(

    Problem: coolant leak from plastic thermostat housing, coolant seeping from center where two plastic halves are pressed together.
    Solution: replaced housing (no way to repair plastic)
