Mustang severe coolant leak

Asked by Marine4024 Apr 13, 2018 at 08:37 PM about the 2010 Ford Mustang V6 Coupe RWD

Question type: Maintenance & Repair

Replaced the thermostat housing oct 16 and there is
again coolant pooling  under the intake behind the
thermostat but now I have coolant all over the bottom of
the vehicle pouring down the engine and I don’t know if
it’s coming from somewhere else because I cannot
pinpoint the leaking. I am losing all the coolant in my
overflow every 10 miles or so .

Everything looks good on the outside . The coolant seems to be pouring off the side behind the belt . Unless there’s something under the intake then I can’t see where it’s coming from

It is the housing again. This is common if you buy aftermarket housings. Even the motor raft housing eventually fails. There is an aftermarket aluminum one which solves the problem.
