2004 eddiebauer 4.6 v8 leaking under thermostat housing

[Ron103067]

Mines leaking on the bottom of thermostat housing its like a plastic sensor.
Wondering what its called and is it changeable without removing intake.

If the plastic on the underside of the thermostat housing has cracked or separated, you will probably need to replace the intake manifold. This thread has some pictures of one that went bad. http://www.explorerforum.com/forums...coolant-leak-on-2006-mountaineer-4-6l.452821/

If you do replace it, this thread has some good tips for the Dorman intake manifold. http://www.explorerforum.com/forums...ke-manifold-installation.456857/#post-3592386
