Could anyone post a diagram, take pictures, or post a description of the heating core hoses. We're not sure which ones go where, which way it flows.

It's a 94 400 with 1jzgte swapped in. This is hopefully one of the final issues we'll have!

TIA

 

I have this same question. I am going through the SC300 FSM and see where the block hose goes to and route that way.

EDIT: I looked at the removal of the engine block step by step and they don't even mention the heater hoses. Er...So honestly at a loss there.

BTW I went to Advance and bought a J-shaped 3/4" hose that had a 180 bend in it after the bend it is about 3.5 feet long.

 

bump - please help!

 

Hopefully this helps, back when i was doing the swap.


Right side goes to waterpump
Left side to valve then to head
