I just got the lines in today. I tried installing them but the fittings don’t thread in. the ones that go into the block and head fit but none of the ones that go into the turbo fit. I’m wondering what the problem is. the turbo is a new vnt with the brass elbows already installed.

in an effort to make sure that the elbows were correct, i checked the lines against the stock vnt i have (with elbows) and they don't fit on that either.

Thanks.

Where the lines ordered specific for a VNT? I know the lines for a VNT are different from any of the other turbos.

yes. the note inside the package showed they're the vnt lines. i've called and spoke to them, they say that the line will most likely fit if they were installed directly into the center section.

having the original VNT sitting there (the one i'm replacing) to pop off the elbows from helped. well, actually it didn't because the lines didn't fit on it either with or without elbows.

dealership can't help because these aren't available anymore. my other post on the other forum (before it got locked) someone said to make runs to the hardware store for different fittings to get it to work. shame, because i was expecting a very straight-forward bolt-in lines.

they also said to make my own.

i have a rebuilt T2 sitting around that i could compare these to if these were somehow packaged incorrectly.

i might have to try the general auto parts store; what are the chance of them actually having them? i was told to grab some from the jy, but chances of finding any of these rare VNT cars still around AND their lines still easily removable without mutilating them is impossible.

oh, yeah. i need the car by sdac too. :o

i will try again tomorrow and get pictures for those who doubt my mechanical aptitude.

Although it probably isn't the best situation, especially with a VNT running high boost, you don't really need the coolant lines. You can plug up the block and the head and everything will still work just fine so long as you let the car idle down after spirited driving.

That being said, you should be able to get the fittings you need from www.jegs.com and make it work in time for SDAC with little difficulty. Are the center sections on the TIV turbos 3/8th NPT? If so it shouldn't be that hard to rig something up.

I can't believe that I don't have a page up on my site detailing how I made the oil and coolant lines for my cars. It cost about the same or a little less than the FWD/TU kits, but I think they work a lot better if you are running a hybrid and offer much more flexibility both literally and figuratively. I will have to see if I can get something up soon.

i guess dealerships only search throughout other dealership inventories and not private businesses....i never thought of that.

thanks d00d!

messed around with the lines again today. i was able to get the return line installed, but only if i didn't use one of the fittings that came in the kit. more details when i post up pics.

the feed line will NOT bolt in at all. i'm gonna run around to hardware stores/performance shops to find the correct fitting. pics to come.

NOTICE: this is not an attempt at discrediting anyone. This is my way of showing my side of the story.

now for the meat n potatoes:

First image: the whole works; coolant line kit. Coolant feed and return lines with fittings. Included instruction sheet. Return line is at bottom.
http://img120.imageshack.us/img120/5038/1060668imglr2.jpg

Everything outside of package.
http://img340.imageshack.us/img340/3982/1060669imgnz2.jpg

The original VNT turbo. 2 original elbows are right below the can. The larger one on top is the coolant return elbow. The smaller is the oil feed elbow. The oil feed elbow is not relative to this situation.
http://img183.imageshack.us/img183/8497/1060670imgbj9.jpg

The kit disassembled in their respective locations. NOTE instruction sheet is placed elsewhere. it did not disappear into thin air.
http://img183.imageshack.us/img183/6328/1060671imguu7.jpg

The fittings being considered: the upper fittings are for both ends of the feed line, they are both the same; the lower fittings are for the return. brass elbow in the lower right hand corner.
http://img183.imageshack.us/img183/7739/1060672imgpq2.jpg

Either of the feed fittings fit into the feed hole in the back of the block just under the PS bracket. The very far left is the intermediate shaft bracket. This fitting is correct.
http://img183.imageshack.us/img183/1846/1060673imgse3.jpg

The other end of the feed line. Fitting is far too small for this stock elbow. BUT
http://img183.imageshack.us/img183/2558/1060674imghi7.jpg

As stated per phone conversation, I attempted to install this fitting into the center section sans elbow. Does not happen. The fitting is pictured here end-on-end with the original elbow. Where’s waldo? Oh there he is!
http://img183.imageshack.us/img183/4033/1060675imgpa7.jpg

Picture of the center section with the feed fitting. This is the bottom of the turbo. Fitting does not screw into center section. Refer to photo above. Vnt spec oil drain hole at bottom of photo.
http://img183.imageshack.us/img183/7618/1060676imgjg2.jpg

This photo shows that the feed fitting has the same thread pitch as the original elbow and/or center section yet not the same diameter.
http://img183.imageshack.us/img183/3314/1060677imgxq2.jpg

Coolant return fitting end on end with the fitting that goes into the waterbox. Same diameter, but are they similar pitch?
http://img183.imageshack.us/img183/2496/1060678imgba8.jpg

Yes!
http://img183.imageshack.us/img183/8830/1060679imggm7.jpg

This is correct for the water return @ the waterbox.
http://img183.imageshack.us/img183/5439/1060680imgex4.jpg

The other end of the return line; the brass elbow supplied with the kit.
http://img183.imageshack.us/img183/2373/1060681imgdu1.jpg

Does not bolt in.

Does not bolt in.
http://img183.imageshack.us/img183/3103/1060683imgfy7.jpg

As stated in the instruction page, the can needs to be removed before installing the new elbow for a vnt. Here the can is removed, below center is the return elbow.
http://img183.imageshack.us/img183/336/1060684imgiw6.jpg

End on end; the original elbow with the new brass elbow. Same diameter.
http://img183.imageshack.us/img183/9636/1060685imgsy1.jpg

Same thread pitch? MAZEL TOV! NOTE the differences in length….
http://img183.imageshack.us/img183/4813/1060686imgfr3.jpg

Attempted install into the center section. Alas, the bane of its shorter length. Can not install into center section unless there is further disassembly of the turbo…. Hello, waldo. Why do you keep getting yourself lost?

Last time on vnt coolant lines…

Another angle just to prove that I’m not Photoshopping.
http://img444.imageshack.us/img444/4025/1060688imgic5.jpg

The silver lining in this rain cloud is that I was able to fully mock up the return line @ both ends as seen here. I neglected to use the provided brass elbow and turns out the fitting underneath fits just right into the center section.

The other end of the return @ the waterbox.

Here is what I can offer to you from experience. The pictures are from a year or so ago when I had a VNT...

***Disclaimer***


I am NOT trying to get into a pissing contest with a vendor as to what works/does not work, just detail my experience and how it had to be modified/worked around to be installed correctly


The blue fitting as the coolant line was too short. This was installed by the same vendor you purchased your braided lines from. Ignore the last piece as that was the extension for the orig. TU header.

Pic #3 the bottom of the VNT28 turbo. Notice the brass fitting on the bottom

Pic #4 back of the block. Ignore the TU fitting/extension.

Pic #5. VNT28 turbo. Notice the stock fitting/elbow is still in the turbo. There is a fitting to get it all to work, but I am not sure of the size.

I am heading out to the shop tomorrow, and I am pretty sure I have some elbows/pieces/parts left over if you need them. I hope the pics help...
