Where do these coolant lines go? (pic)

[rusty959]

Ive been having a hard time tracing where these lines should go and searching/manual isn't helping any. After my recent engine swap I have these two lines coming from the turbo area. One is the coolant to the turbo and one goes to the oil filter housing. Since the one goes to the oil filter housing I thought it was oil but it seems that when I filled the car up with coolant some coolant came out of it, which completely confused me. Either way, I don't see where an oil line would be hooked up, but have two ports on the thermostat housing where the lines could go. Do they both hook up there and if so which one is which?
Thanks for any help you can give.

None of those hoses that you selected should be for oil.

The oil feed line for the turbo is that hard metal line off the side of the head.

The bottom of the water neck should have 1 line that connects to the turbo. The second line that connects to the turbo is underneath the water pipe that runs across the block.

That other line that runs to the oil filter housing is in FACT a coolant line. Coolant does run to your oil filter housing. A coolant line is used there so that the oil doesn't coke after you turn the car off...helps the oil cool down a bit.

Can you take a pic a little farther out so i can see exactly where on the water neck they are connecting?

Here is a pic of my engine to help you see a little clearer where they should go

The L shaped hose on my car is one of my coolant lines to the turbo, the second is just below it. You can hardly see it, just the tip.

The line off the top of the water neck is the line that runs to your OFH.

Check our my profile pics, you have the 6bolt? If so the bottom line on the thermostat goes to the turbo and the top one goes to the bottle overfill

Ok thanks for the help guys. Unfortunately I don't have a better pic. I thought I had some but apparently not, and when I was over there earlier tonight I forgot to take better ones. I think I understand them now, its just weird how they don't line up like I thought they did before. The coolant reservoir has two lines... if the one goes to the port beside the cap, where does the other go?
Bluefire16: Thanks for the clarifications. From the looks of it, yours is positioned a bit differently than mine... is it a 7 bolt? I think the ports would still be for the most part right.
EagleTsiAWD: Yes it is a 6 bolt. The biggest thing is the two lines that dont include the overflow. I didn't want to risk mixing oil and water...

Yeah, 6 and 7 bolt are different in thermostat housing. One of the lines of the overfill cap hooks up to nothing, It just points to the ground. The only wrong I see in your pic is the coolant line for the overfill bottle, it should be hooked up on top and the turbo line should take it's place.

On a 1G, it should look like this:

Red - "Middle" nipple, the hose makes an 90* bend to connect with the hard line that connects to the rear of the turbo.
Blue - To the reservoir, notice that it is connected on top near the radiator cap.
Green?Yellow? - "Lowest" nipple, the hose connects to the hard line that runs to the oil filter housing (OFH). All 1G turbo cars except for 1990s had a water-cooled oil filter housing from the factory. The 1990 turbo cars had an original external (air) oil cooler.

There is only one line going to the overflow bottle, other than the other end stick out to the ground.

On the 6 bolt, the hose on the right coming off the water neck (basically where the Radiator cap is) is the hose going to the overflow.

Once you have just the overflow connected, 2 should go to the turbo and one to the OFH like already stated.

Anybody know what the hose diameter is for the turbo feed and oil filter housing feed?

 

[19Eclipse90]

They are 9mm in diameter which is roughly (a little less than) 3/8" as I'd imagine most part stores won't have metric-sized hose in stock.
