Bloody 1.8 owners... :rolleyes:

Yeah, I think you're right. Lathe the thermostat groove into both sides, and keep the "aux" hole as close to horizontal as possible without moving the CLT hole so far upwards that it causes the coolant sensor's connector to interfere with the CAS in the 1.6 (intake cam) position.

NB users flip the spacer over, and use the "aux" 3/8 hole to feed the heater.

Doesn't change the design a bit.

Nice.


edit: Wait, that won't work, will it?

(need to draw this out and analyze it)

I think there may need to be something on the M12 port to bring the sensor away from the spacer just a bit, just to keep the tip of the probe from interfering with or touching the thermostat.

If the position is right, it'll clear.

+1.

Let's get this installed.

just looking at the parts diagrams for the 99 and 01. flipping wont work. Our bolt holes are not vertically aligned.

Our temp sensor comes out almost in front of the upper left bolt slot so it should probably be moved anyway for the spacer.

However, if you just rotate the thing on its center axis so that the bottom is the top, it puts the heater outlet (3/8) and temp sensor very close to where they normally are. And close means "so the wires reach" which is fine. The temp sensor would just be under the heater hose.

the question is: will the slight upward angle of the heater hose outlet be a problem for the heater hose or not?

Ah. Ok. Nevermind my comment then. lol

Let's get this rolling! I need to put my engine back in the car!

I must have spent four hours last night messing with the design, and I never even thought of that. :rolleyes:

Have another look at the picture from RotorNut's msg #121. This is pretty typical of how things were done with the JR spacer, and the heater core feed is obviously above vertical:

I don't know how much offset is tolerable, but it's an interesting idea.

The alternative, of course, would just be to offer two separate pieces- one for the 1.6, and another for the 1.8. Nothing else is cross-compatible between these damn engines, why the heck should the spacer be? :D



Yup. I'm happy with the design of the spacer as I posted in message #239 (for the 1.6 cars, anyway) and I want to buy one, along with the pipe.



EDIT: I have one other idea, but I need a clear picture of the back of the head, preferably with it installed on the block with the CAS and coilpack in place. It can be a 1.6 or a 1.8.

Damn.

While you guys debate your part:

Stephanie any idea how much this is going to cost and when it'll be available?

You are correct. We ran into that Friday when checking the thermostat and sensor. We did put a spacer in there for that version. I am thinking the final version will be raised off the housing slightly.
Stephanie

Not yet. I need to get some more info from the machinst first.
Stephanie

Hopefully soon. I'm waiting on your kit to install my engine... :)
I'd wait on the intake manifold too, but that's still looking to be way too far off. VICS will have to do for now.

Brain, that looks good. Looks like the 1.6L water neck just barely fit even with cutting the top of that plug bolt off.

there's about 1/2" of clearance. If i didn't cut it, it wouldn't have fit.

I think the spacer can be made shorter also just as long as it is deep enough to keep the temp sensor off the thermostat.

Don't know if anyone else helped you out with this, but I took a couple pictures tonight while I was working on my car, hopefully this helps:

Attachment 207533

Latest version. I think this is the one that will work - if I got the orientation correct. :)
Stephanie

I think I'd want the port for "Out To Heater Core" to be closer to the sensor bung. In this orientation, the port would be pointing straight down at the transmission when mounted.

problem solved.

Nice Brain, I was wondering what you were doing when that first code popped up. :) Although there needs to be a "nothing" option.
