So I was swapping out my coolant temperature sensor and am afraid I broke something! I was removing the 3 way rubber connector and in the process of hacking off the clamps that attached it, i broke the fitting it connected to on the bottom.



#3 is the fitting I broke off, #2 is a metal nipple that goes into the head, and #1 goes left into another hose. This is between the firewall and the cylinder head.

Is this an oil line? Anybody know the part that I broke that I now need to replace? Much appreciated.
