I understand that you can use the RST oil cooler on a Zetec Turbo conversion. Does anyone have a diagram or accurate description of that water pipe set up on their ZT?

I've been staring at it and scratching my head for a while now and I'm a bit confused.

 

You could use the cooler from the ST170 engine, I was gonna use it on mine but space did seem a bit tight and getting a nice run for the hoses looked like it was gonna be a little tricky, so I never bothered, could add it at a later date.

For the plumbing I used the cvh thermostat housing and connected it to heater matrix.
The pipe that comes off the bottom hose and runs around the back of the engine, do away with the Y piece and use a joiner to connect to heater matrix. If I was gonna run the cooler I would expect this would be the hose I would tap into/divert.

 

So you are running without one?

 

Yeah didn't bother with it.
