Coolant flow direction ??

Hi all,

I have searched and just want to make sure I have this correct. The FSM doesn't clearly show the coolant outlets and the return routing. Based on the pic below is #2 and #3 the correct direction of flow to and from the turbo? I am going single turbo with a GTX35 and want to ensure I have the lines correctly installed. Thanks for the help!

Cheers

Are you retaining throttle body coolant? If so your only real option is to use the 2 other 3/8 nipples you have labeled turbo. Doesn't matter which way you flow the coolant through the turbo. Otherwise you can you the tb nipple then the bottom turbo one. 4 is to the heater core so that should be left as is.

#2 is turbo in and #3 is turbo return, #4 is heater core return.

Thanks ZE, so essentially the reverse of what's in the pic.

Based on IRP's feedback it shouldn't really matter, but I like to have the details for peace of mind lol.
