I have an 03 gt and I just found a coolant leak on the front of my intake manifold. It is in the front corner under the termastat housing. Do you guys think it just a bad gasket? If so, what is involved with replacing this. Any one else with the new metal/plastic manifold have this problem?

thanks in advance.

So you've got the metal crossover on yours? I was going to say, if Ford replaced it for you, you could bring it in and make them fix it.

When you say "under the thermostat housing" do you mean between the hose and the housing, or do you mean underneath the entire housing? If it's between the hose and housing, then it could be the gasket, or improper torque on the bolts.

The leak is under the thermostat housing. It is either comming from between the metal and the plastic or between the head and the manifold. There isn't enough clearance to see exactly were it is comming form. I searched the recalls, tsb's and the forum for anyone else that may have had this problem but it looks like they are all older model years.

your car is a 03 so there was never a plastic crossover manifold on your car.

see if you can get a presure tester and see where the leak is coming from. if it's not from the thermostat housing then i would replace the intake gaskets.

I'm thinking the bolts aren't torqued right. Aren't those the last bolts to be tweaked? Check that and maybe do that pressure test. Since you have the aluminum crossover that's ruled out.
