i have a Evo Big 16G on my 6 bolt 1g ... i rebiult my turbo and i went to put it back in started the car and the turbo got wicked hot ... the weird thing was the actual radiator lines were cool but the water lines for the turbo were hot. any ideas would be good.

The turbine side is supposed to get wicked got..You can light a cigerette off of it after a few minutes at idle..And coolant is over 150 degrees..
The exhuast is what spins a turbo so I'm not sure if were on the same page here.
The lines in the back and front are for coolant..The one on top is oil feed, and the big one at the bottom is oil return to the oil pan..

Replace your thermostat.

You should probably ask him if his fan was turning on before you tell him to replace the thermostat..

i ran the inlet line to the main cooling line strapped to the block connected to the water pump .. and the outlet line up on the radiator neck

I'm confused.. One of us has the lines hooked up wrong..Mine are all in the stock location, and all run to the thermostat side of the engine...You didn't hook the lines up to the stock location?

no cause i got the motor seperate and have pieced it together little by little ... can you take a pic of your lines so i can see where to attach them

The two in red obviously..This is the best pic i have of the coolant lines..Its pretty dirty from all the colant and crap but you will get the point..

Nope, chances are he could stand to replace the $22 part anyway.

Chances are, correct..

How about.... Did you bleed the air out of the coolant system after you put the turbo back on and filled up the coolant?

Also, if I read correctly. You hooked up a line to the turbo from the port closest to the water pump on the water tube?

That should be the line from your OFH area. At least it is on the 98 tsi awd, 91-93 gsx, gst, tsi, and rs's I work on nearly every other weekend...

Coolant flows cool to hot within the cartridge for a reason....this is so the water will continue to flow through the turbo even after the engine is turned off. The front water line which goes under the turbo and connects to the water pipe is the cool water; the rear line which connects to the thermostat housing is the hot water.

i think i have my lines backwards cool to thermostat and hot to cooling tube... also no i did not bleed my coolant system how do you bleed it?

The way I burp the system is to fill it all the way up, close the cap..Push down on radiator support a bunch of times, or push down on the bumper repeatedley..Add more fluid, and do it till no more bubbles come up, and you can't put more fluid in..
