The two plastic coolant fittings that are prone to failure are as follows:

"Y" fitting located on back of cylinder head between engine and firewall. This fitting is difficult to access but can be accessred easier by removing the valve cover. If doing so, you may want to purchase a new valve cover gasket and spark plug seals as well. The part is rather cheap, I think around 7 bucks.

And the other fitting located on the block underneath the lower intake manifold. This part requires removal of the upper and lower intake manifold. It's not as common to break, but should still be replaced. IIRC it costs about 15 bucks.

And a link to a great cooling system rebuild thread where those pictures were found, written by CirrusSR22:
