I did a c5 block swap into my friends 00 si with a '90 pr3 head. The type r thermostat housing has 3 coolant lines coming off of it, 1 to intake, 1 from heater (Chassis) and one small one. The stock b16 housing did not have the small one. could someone please tell me where it goes so I can tell if I missed a connection (or if the type r chassis/head/intake components required the extra line). The line I'm looking for is the one on the far left side.

 

nm, he decided to tie it into something else.
