I just did some work on my system tonight. FWIW, the Kia waterneck is a different size than the Mazda one. Will probably use a larger hose so be prepared for it to be too large for the radiator connection. I couldn't get the OEM upper radiator hose on it.

I think now I'm going to be doing what Brain did and cut the port down on the 1.6 neck and finding something to plug that hole, unless I can find some better fitting hose for the Kia piece. However, the spacer I had made locally is 1 1/8" thick instead of 1" so it's going to take a little more work. Brain, do you remember off hand what pitch the bolt was you used?

Dude just go to the auto parts store with the water neck and find something. I'm using the same neck and I have an oem sized sensor adapter at the other end of the hose and it seals with no problem.

It's M16x1.5, it's shown in my pictures.

I agree with Phil, there are a ton of hose to choose from. Most stores let you browse the selection.

I know you have that one. And that's what I did, I went through the hoses behind the counter at Advance last night and was not able to find anything that fit well (and also gave me the right angle to get the hose around the intake manifold), everything was too small or too large or was some crazy design. Of course, they don't keep as much in stock as the other stores, but then again, this one is 5 minutes from my house rather than 35. Guess I'll try a better one today after work.

*edit* Thanks Brain. Didn't even notice that the first time I looked at the pictures. Sorry.

I just found an ideal hose to do a reroute.
I have no idea what car its for (neither did they guys in the store), but it's a Gates 3526
Just need to cut it under the throttle body and use S-shaped hose to connect further to the radiator. Pics are in a Westfield so the last bit is a bit different :D

Oh, and this is a good way to block off the front. Cut off, thread with M14x1.5 and put an oil drain plug in there. This is a 1.6, but I think a 1.8 could be done in the same way.

Doesn't that put the temp sensor in a place with no water flow? At least in the stock position it has the flow from the heater loop.

The hose is cool. Moving the coolant sensor wiring to the front, not so.

Actually moving the sensor is a good idea. There's always flow towards the turbo (although the hose is still hanging loose in that picture). Try pulling one hose off while it runs and see what happens :).
Even without turbo, there'd still be enough flow through the ISC.
