Thermostat 155 q4

Hi everyone
What are the options on the thermostat? I can't find it on sale. EBay sells separate inserts, but I don't know how to disassemble the case.

Hi Babai,

Q4 Thermostats are almost impossible to find these days, as an alternative you can use one from a Fiat Coupe 16v Turbo, I think if you still have your EGR system you will need to cap one of the pipes, but other than that is should fit.

The problem is that Fiat coupe also does not have such thermostats

Supply is still OK:

Not long ago I bought thermostat for Q4, which was laying in storage of one local italian cars part store from many years from what I understand, but didn't know that there is similar, but not the same used on Coupe 16VT and integrale. I made photo of it then but to side, which attach on the engine and that is the same from what I see. Have to check it on other side to see if that was a find.
