i just got my theft recovery evo that was missing turbo so i got new turbo in and cranked the car. Coolant wasnt flowing on turbo side. I was wondering if it should or not till it warms up?

 

Not 100% here but I'd assume the thermostat would have to open up before it would start flowing. Don't quote me though it's just an educated guess.

 

thats what i tough, i did not warmed the car up to its normal cause i was afraid of turbo fail. I attached clear tube to make sure coolant flows when car warms up. Any input on routing turbo coolant lines? Upper aluminum turbo hose connects to upper aluminum hose on the head and bottom to a bottom right? Sorry for dumb questions but my car was all srtiped and im almost to the end finishing last steps. If any of you have spare t case, let me know

 

I could be wrong, but I don't think turbo coolant flow is affected by the thermostat. I'll have to look in my thermostat housing again.

 

Just in general (and I doubt the Evo is an exception), the coolant does not really flow until the thermostat opens up.

 

Don't think it does until it warms up.

 

I looked and the turbo should get coolant flow at all times and is unaffected by the thermostat. If you open up the housing you will see. Basically everything below the seam (turbo, temp sensors) of the tstat housing will always have coolant flow to it. The tstat determines if it flows out of the upper rad hose (hot) or down through the bottom of the housing bypassing the rad (cold).

If you don't have flow through your turbo, I doubt you have any flow at all.

 

Glad you were able to verify this biggie.

Might have bigger coolant problems then just not getting coolant to the turbo. Clogged radiator....clog in one of the hoses....air bubble....ect. Might want to start checking that and let us know what you find.

 

You won't destroy the turbo just by letting the car warm up.

 

True, but he will destroy his engine if there's not coolant flowing through it. If there's not water in the thermostat housing then his temp sensor probably won't read and he won't have gauge indication that his motor is overheating.

 

Ill do a coolant flush and see what happens then. Any input or line routing? The one that comes out from top of the turbo connects to top aluminum hose on head and bottom to bottom? I bet thats the way it is but its always good to double check with u guys

 

domantas- i just tried to take a picture for you, but theres way too much stuff in the way for a clear shot.. my intakes coming out this weekend and ill take some pictures for you if youd like, just shoot me a pm to remind me.
from what i could see the top line coming off the head mates with the front of the turbo and the bottom line meets with the rear of the turbo.
the top line on the turbo is the oil feed and the bottom is the oil return.
this is on a stock turbo evo VIII.

hope this helps and again shhot me a pm if youd like some pictures

 

i would really appreciate a shot. I already have my oil lines hocked up so its good, im only missing coolant hoses.

the line with the red arrow mounts to the foward side of the turbo

and the yellow arrow mounts to the rear of the turbo

hope this helps, if you need any specific pictures let me know

 

i cant believe someone took their time making a picture for me and draw all the arrows realy apreciate your time, ur awesome!!
