No Pic, but pretty easy to explain. On the forward end of the exhaust manifold there is a coolant hose that ties in down by the fresh water pump. Tee that line for hot water out. On my engine there was a plugged hole on the fresh water pump housing. That's your return point.
The exhaust manifold has nice hot water with a continuous flow (not interrupted by the thermostat). It's important to tee the line (not divert it) so that flow through the turbo and exhaust manifold is never reduced or interrupted.
Install valves at both points to be able to isolate the loop in the event of a leak.
I'm tired of fast moves, I've got a slow groove, on my mind.....
I want to spend some time, Not come and go in a heated rush.....
