CVH On Carbs

Below is a picture of the inlet manifold on Gus's donor. His finger is touching the sensor for the dash temp gauge.

Yours should be similar.

I wouldn't worry to much about the Sierra fan switch as it won't fit the FWD thermostat housing. You need one from a Escort or Fiesta that was fitted with a cvh. Something similar to the below. But a standard one would do.

Ok good to know, I guess the escort or fiesta fan switch will then attach to the fwd thermostat housing? For the temp sender, still a bit lost as mine doesnt look like gus's, if you look at this picture, you can see I don't have anything like that next to the thermostat?

Could be in a different place, but it will be on the manifold, and should look like the one pictured.

Ok so I approached this a slightly different way this time. Having seen your picture of the connection I found that on the loom and luckily I had numbered it when I took it off. Low and behold the same number was on the bottom of the inlet manifold so I took the bit out and it looks like yours although it doesn't have the same bit sticking out of the top. Does this mean mine is broken or just different because of it being an injection engine?

And had a play with the fan switch off my donor manifold. Turns out the 1.8 cfi fan switch has the same size/thread as the polo rad and the fwd thermostat so saves me buying a new one So I reckon I'll leave it on the fwd thermostat to plug the hole there and leave the polo fan switch on the rad to plug that hole and then just route my expansion bottle bottom hose to a T joint on the bottom hose rather than attempt making something to fit into the polo rad fan switch hole.

That's definately the engine tem sensor that you are holding in your hand

The centre part is missing ( Should look like Gus's ) No real drama there, you should be able to get a new one without any dramas.
If you are going to fit an aftermarket Temp gauge the chances are that you will need to change that anyway

Pleased to see you managed to get your inlet manifold sorted

Yup took awhile but got there in the end, bit annoying really that the haynes workshop manual doesn't really give much detail around the cfi engines. Just need to drill & tap a hole now for it in the manifold. Any idea what thread the temp sender should be? It looks close to an M10 but an M10 nut only screws on a little way before it stops so I'm guessing it's an imperial thread of some kind?

Hi

I got a sneaky feeling that it has a taper thread ( They quite often do )

Will try & have a look for you later, it just so happens that I have a CVH manifold & carb on the workshop shelf & the usual sizes of taper taps
