ok back of the gsr black there is a coolant connecting pipe between the thermostat n waterpump??...there is a hose that runs off of the pipe and i have no clue where it would go. on the da's there is a hose from the heatercore? that comes from the firewall....does that hose from the firewall go to the connecting pipe?...if ne1 has answers i would b stoked to hear...

Thnx

 

Yes, connect that metal pipe to the heater core hose. Ive seen some people just replace that whole metal line with a hose. Either way you choose.
