Gents,


I've recently replaced the water lines going to my turbo on my 4agze (AE101) turbo set up and was wondering which way the water is flowing through the turbo.


Some say there is no specific water outlet or inlet on a turbo but I believe there is due to the thermal siphon effect.


Having said this I want to make sure my lines are connected the right way so this effect can occur.


The line from the low side of the turbo is T'ed into a line that on one end is connected to the valve that is operated by the heater control dash. The other end of that line goes to, which I believe is, the external thermostat.


The line from the high side of the turbo is T'ed into a steel line that runs on the right side of the engine (when sitting behind the wheel and looking forward) which I believe is the water outlet from the head. This steel line is then also connected to the external thermostat (with a rubber line).


Can someone tell me which way the water is flowing? Am i correct in assuming that the water coming from the head is my water feed for the turbo?
