    Hi All,

    Just in the middle of having my engine put back together. Needing to get some parts that have corroded or snapped.

    Anyone know what this piece is? The one being pointed at.

    Or is there an exploded engine diagram thats available?

    Its just above the exhaust manifold.

    Many thanks,

    Looks to me like a temperature sender, probably for turning on an electric fan

    Correct. Thermostatic vacuum switch. Should be two stubs for vacuum pipes, but they appear to be snapped off.

    Thumbs up for that it is a thermovalve , one pipe will go to the fuel metering unit and other to the regeneration valve . The plastic tube parts that are broken off , and missing from the valve are not the same as one is set at an angle and one upright . The upright one goes to the regeneration valve , and the angled one to the lower part of throttle or metering unit .Dont know what the engin is but most are like it . pm sent

    Thanks guys. Yes it's an R107 1985.

    I posted late after coming back from holiday. I usually shout at my users of they don't provide all relevant info!

    If anyone can link an engine diagram I'll look up the part number. I'll Google more tonight.

    Many thanks.

    banman you part number will be on the valve .The opening time on the valve is the one you look for .And come by colurs white and black red with black bands . You need to pull the old one out .Dont do what i did removing it and snap off one of the two tubes,. But in your case this could happen when your fitting ..

    banman this is the diagram and the valve .You will see the markings on the flat part .Thats the value you look for on your valve .I think this is the right valve but check it with yours.Diagrams are a 100000 fold in images on the google search page, look to the r/h side top of google search .You will see - images click on it to bring up another search page .I put in R107 engine vacuum diagrams .Nice car by the way one of the true classics.Looks like you have two thermo valves ..
