Default coolant re-route radiator hose touching pipe

doing my own home-made coolant re-route and i'm wondering if I need to get a different radiator. the outlet is really close to the intake/charge pipe and well, is this bad? or can i live with it?

Most of us have that same problem. You could trim a bit off the hose end that goes to the upper radiator inlet, to get the hose moved away from the throttle body pipe just a tad.

Rotating the assembly of the radiator hose and cross-pipe around the point of the radiator inlet will also buy you a tiny bit of extra clearance.

Also, is that up-pipe fully inserted against the throttle body as far as it will go?

Yep, had the same problem. You gotta get creative. It's not really that big of a deal unless you can see the hose is...unhappy about bending in a certain way.

yeah, the pipe is pretty much touching the throttle body.

I've already cut part of the radiator inlet as it was out even further, and i've cut about 3 inches off the radiator hose. Not sure how much more I can go and feel safe. as of now, there isn't a lip on the radiator inlet :(

oh yeah, I forgot to add the pipe is sort of a one off begi, but it's because they messed up on the sensor tap (welded it too high), but it still works and I got it at a discount. length wise, I'm guessing it's the same as the "normal" one they sell

I had that problem, so I re-did my coldside piping to tilt towards the middle a bit.

Wait until you get a thicker aluminum radiator, then you'll really have a problem.

I forget, is it any better if you route the hose to the right of the pipe and then behind it? Hope not, seeing as though you've already cut the radiator.

you 1.6L's have it easy. 1.8's have less room. I am not sure what I am going to do yet, but I think I have to re-do my IC piping

I have a '95 with an FMII kit and a 55mm Koyo. Looks like I'm going to be hating life when I go to install the M-Tuned reroute.

I had the same isssue - I cut another 4" piece of hose and overlapped and zip-tied it on at the contact point - that way I wasn't chaffing the actual coolant line itself. Same with my oil lines from the sandwich plate to cooler...

oh yeah, and one other question. Since I'm using a begi spacer for the rear thermostat, but I want my egr. I have two egr valves that I've bent out from their respective sides and I plan on getting them welded. I could pay someone to do it, but then I have it mocked up on my spare motor. I have experience silver soldering, but not sure if that's going to cut it...

Check this thread for a ton of pics of that said pipe for ideas.

I ended up having outlet re-welded at an angle, but there are a lot of better options

Thanks Preluding. I guess I had a search button fail. Very useful

I think I'm gonna bring the egr tube to a shop down the road and just have them weld the two pieces together. my little torch just aint gonna cut

Look at post #47 in that thread. That little hose from NAPA works great. I had less clearance than you - about an inch! The chrome thing is just from the plumbing department at a hardware store.
