I have a problem with the coolant fittings (inlet and outlet sleeves) under the intake manifold.
For conversation purpose I call them press fittings, see the picture I attached (red circles).
There are two of them and both rusted of and broke, I fixed the larger one (close to the firewall), but now the smaller one under the intake right above the spider water outlet broke off.
If really need help on how to replace it (get it out of the block), and maybe someone knows what they're called and where I can get them. http://www.hbwdk.com/pics/10.jpg
