Anybody out there used a Zetec 2.0 engine in their Locost build?

I'm doing that, and am at the stage of figuring out the cooling system. Most of it is pretty self-evident, but when I look at the T-stat housing, there are LOTS of ports. Since I don't have the luxury of a donor car to track where all the hoses are supposed to go (and there aren't any in my local wrecking yards anymore, either), and I can't find anything online that shows where they all go (there are several diagrams, but they only show a couple of the hoses), I'm at a loss.

Failing that, anyone have a Zetec-engined Focus they can look at to give me some ideas?

Thanks, folks!

I can't really help, but I'll be trying to sort out the same things soon with the Zetec in my Europa. I have looked at the diagram from the locostbuilders.co.uk site along with a PDF guide on converting a Europa to a Zetec, but neither show exactly which of the three smaller ports are. I would assume that the smallest one (should be pointing up) is to go to the expansion tank, the other two either go to a bypass hose or a heater matrix.

Yeah, I've scoured the UK Locost site as well. Lots of diagrams showing the major ports on the housing, but none showing the purpose of the smaller ones.

This is about the best one I could find so far, if it helps you...it does address the heater matrix plumbing, but still doesn't go into the smaller ports. On my engine, there are also a couple of pipes coming out of the block/head right at the T-stat housing, and I have no clue what those are for, either

Pete at raceline is doing bits and pieces for Zetec into 7`s . He does this http://www.raceline.co.uk/products/part ... tegoryID=4

If its out of your price range its something easily copied I would have thought.

In your diagram it looks like you're using the heater as a bypass and have blanked off the actual bypass circuit. Also, the smallest port on the top of the t/stat housing should go to your overflow bottle as well as the small port on your radiator neck.

As for the other smaller hoses, I haven't a clue. I would hazard a guess that they have something to do with running the stock computer/fuel injection. Seeing as you're on Webers, I would think that they are redundant.

I'll take a picture of the t/stat housing that I have when I'm in the garage tomorrow. It may shed some light.

Thanks, cs3tcr! That may, indeed, shed some light. I suspect, as you say, that the smaller pipes had something to do with the computer in the original car.

That's part of why I went to Webers - some of the sensors in the original CPU would have been easy enough to fool, but others would have been extremely difficult to get around, and some (if not properly fooled) would instantly have put the engine in run-home mode with no way to fix it.

Ignition was the tricky bit, as it was originally driven by the ECU. I ended up going with an ignition from Quads4Rods (thankfully, I got mine a few years back - they are now breathtakingly expensive!) as I'm just not computer savvy enough to figure out & program a Megasquirt system.

In my case, when I got the engine, it didn't come with the ECU & associated pieces, so I end up with a bunch of wiring & plumbing connections at the engine that are mysteries. The electrical stuff isn't much of a problem, as I can just ignore them, but the plumbing...I don't know which ones to ignore, which ones to cap off, etc. So far, the T-stat housing has been the biggest question mark.

I did look at the Raceline Water Rail as well, and it does look like a good unit. My header, though, precludes the use of one, due to its shape & routing.

I'll be buying a radiator & fan shortly. Looks like the best deal are the welded aluminum ones (for a '90's Civic). My buddy bought one, and it fits perfectly & it seems well made.

I have lots of other issues to deal with, too - like, trying to get a 1960's Smiths tachometer to talk to a bespoke, modified (in permanent, altered, run-home mode) GM OBD-1 ignition system...

Zetec,
Where about's are you in BC? I've got a new alloy Civic rad gathering dust that could be had for $40....

I'm planning on using Megajolt on my Zetec, as its nearly a plug and play. Plus I've had one running a Smiths tach in my old Seven with the MJ.
