    Hello, I'm trying to figure out where the leak is coming from. Tried to pressurize the cooling system but still can't find it. Please check out the pictures in the attachment. The red arrow points to the area where I see the water dripping.

    Do you think it's the water pump? Or the thermostat housing?

    Thank you!
    Joe

    I second water pump as well. Do you know when it was last replaced? If it has been a while might as well replace the pump and along the way replace the timing belt and its components as well.

    I bought the car last year as a project. It has couple issues but overall it's in great condition. It has 197000 miles on it and I don't if this is the original water pump.
    Just haven't had time to work on it until now.

    If you don't know...it's time for a full T-Belt w/water pump and pulleys replacement.
