Thanks mark, I'm struggling with this bit!
The only electrical connections I need to keep are the ones that go onto the thermostat (think there's 2). I don't need any of the vacum hoses either that went on to the donor manifold? So the plate I make to bolt onto the engine for the manifold I just don't cut a hole for the coolant and that blocks it enough? When you say remove the core plugs on the end of the engine have you got a picture of what these look like or where they are as it's hard to see in your coolant outlet picture. Will the thermostat I've got from my 1.8 cvh (injection one) work? It bolts onto the front of the manifold by cylinder 1. So again I'm a bit confused about how this gets connected to the core plug outlets mentioned above. |

At the flywheel end of the engine there are 3 round plugs in the end of the head, you can see them in my pic just below the dipstick, thats where you need to fit a thermostat housing
Your 1.8cvh wont fit you need one from a 1.6 front wheel drive escort, i think davedew is doing this so may post a pic for you to clarify what you need You will only need 1 temp sender in the water system for your dash temp guage You wont need any of the vacuum take offs Yes you are correct just dont cut a hole in the manifold flange for the coolant outlet and this in conjuction with some thick gasket paper/sealant will make it water tight Just take it one job at a time and ask questions as you go, dont worry about things that are too far ahead Get your engine and gearbox in make your inlet manifold and get a thermostat on it then take it from there |

Nice one, thanks a ton for the help mark
My engine/gearbox is in now and bolted in. Got the loom out and have layed it all out so things are in the right sort of area. I'll have to source a thermostat from a 1.6 then, is it only escorts that had a 1.6 cvh? Any idea what year range had them? If you could post a pic of one davedew or anyone else it would be appreciated! For the inlet manifold, is 3mm plate good enough to make the engine & carb plates? Also for the connection pipes, what kind of thickness pipe should I use? I'm guessing the inside diameter needs to be the same as the carbs (36mm) and should it be bent into a more oval shape to match the holes on the engine head? |

3mm wont be thick enough, personally i would want at least 8mm for the engine side as you want it to be as flat as possible, nothing to say you cant go less as long as its perfectly flat once its finished 2/3mm for the carbs pipes will be fine as you say just match either end with carbs/inlet ports as closely as you can Are you using the carb rubbers off the bike? i used silicone hose on my cvh install but when i made a new manifold for the new engine i used the bike carb rubbers & it seems a better job as you dont have a lip inside where they join the carbs as you do with silicone, much more secure too The carb rubbers are also fuel resistant whereas only specialist silicone hose is and is quite expensive Also i have heard stories of carbs falling off when mounting them with silicone, mine never did but theres not much stub to mount them on the carb side |

Ok makes sense I need something really thick for the plates.
My carbs didn't come with the rubbers but thanks for the heads up, I'll try to source these as well and avoid the silicon route. |

I believe the thermostat housing from the 1.4 cvh fwd also fits. I think that's what I used.

Picture time.
Below is a picture showing the back of the head with the core plug that you need to take out. It is the one with the three tapped holes around it. The next picture shows the fwd thermostat housing bolted to the back of the head. Any further questions just ask. Cheers Dave

Nice one, thanks for the pics dave, that makes a bit more sense now! I'll need to take a trip down the breakers to try and get a thermostat at some point. Any idea which years escorts had them in, and if there's an easy way to tell the engine size by looking at it? (wasn't there escorts made around the 1.1-1.2 range which I'm guessing won't work?)
Also I've been looking at sourcing the CHS to make the manifold and I'm struggling to find something with 3mm wall and an inside diameter of 36mm to match the carbs. Would it be better to go slightly bigger say 42mm OD/39 ID or something a bit smaller like 38mm OD/ 35mm ID? Last edited by brainbug007 : 8th August 2011 at 11:53 AM. |

Basically if its a cvh and front wheel drive the thermostat housing should fit.
The housing was the same across the Mk2 XR2 & Mk3 XR2i Fiesta as well as the Escorts. Age range would be late 80's to mid 90's I think. The tube I used for mine was 42.4x3.2 CHS. Closest like you say to the 36mm of the carbs. If you get stuck let me know as we keep it at work. I could post you some, or seeing as you are only in Bristol it isn't to far to come down to have a look at mine & Gus's car if you need.

Ok thanks for the info once again about the thermostat, should help narrow it down a bit.
It's ok for the steel, I got it from bej engineering on ebay as they had a good price for 1m of 42.4x3mm chs and a couple of steel bars to make the plates out of. I was more wondering if it would be better to having something wider or smaller as no one seemed to do anything with 36mm id. Out of curiosity at this stage, once I've got my 2 plates made with the tubes connecting them, how do the carbs get attached? Surely they're not only held on by the rubbers? |
