Agreed. Temp gap too big anyway. The thermostat housing you need must have the “step” to allow the new thermostat and rubber seal to seat. The housing you were supplied is the wrong one for your engine/cylinder head.

For which bit fella?What is the part number? Do you still have the bag?
But all the parts I have are sold in the z3 fan delete mod kit so they know they must not fitAgreed. Temp gap too big anyway.

If the stat and seal fits into the housing like in figure 6 it would be ok. Either the housing OR the face of the block/Cyl.head has to be flat.View attachment 252169
So the separate thermostat should sit in the block like this. My engine doesn’t have that step so am I limited to only being able to use the combined housing and thermostat
Sorry I gave you hardly any info did I. It’s a 2.8 6 cylinder 1999 pre facelift wide bodyWhy 3 stats? How do they fit together? Is this a 1.9 4 cyl. Engine?

Mines the 2nd diagram fellaView attachment 252173View attachment 252175
two types of thermostat housings and thermostats for the 2.8.
probably a technical update on later engines?
Check these diagrams and see what is yours.
i bet they sent you the wrong part. I may be wrong. I am not an expert.
Cant help more. I guess the instructions you follow refer to 1Mines the 2nd diagram fella
It’s the fact you have to use diagram 1 as you can’t get a thermostat/housing combined unit that opens at 80 degrees instead of 89Cant help more. I guess the instructions you follow refer to 1
I’m not sure my mechanical capability’s stretch to being able to swap them over. I bought brand new hoses and jubilee clips as the originals with the spring clips had a slight leakCan you not swap one thermostat into the other housing? Which is the original from the car? Does it have hoses with jubilee clips or spring clips?

The housing in this pictures should bolt onto a flush face with no step, sealed by that "O"ring. Why can't you use this, because the stat's is too low temp?View attachment 252179
without a milling machine I don’t think there’s any chance of swapping the thermostats over
I’m just going to have to call it a day with the fan delete and revert back to buying new old style hoses with the spring clips and replacing the viscous fan clutch. A valuable lesson learned I think. Don’t keep throwing money at something without fully doing your research!!!If you do that you will have a hose with a jubilee at one end and a spring clip at the other. So the other end will have a jubilee clip on a hose pushed onto a smooth stub. This will go from bad to worse, possibly even blowing the hose off that smooth stub even pressure builds in the system.

I just popped down to the workshop and tried a little experiment!If you do that you will have a hose with a jubilee at one end and a spring clip at the other.
