  1. 164 3.0 24v thermostat alternatives

    164 & 168 (1991-1995)
    Hi, need to source a thermostat for a 1994 164 3.0 24v manual. Some indications are the GTV or 164 12V versions will fit but confused as to whether I should be looking for just the insert or the top housing with insert in place. Have gone through the sheered bolt issue the last time it was...
  2. 105 TS: Operating temperature

    Engine Repair, Diagnostics & Rebuilding
    A quick question: Is there a downside of choosing a colder thermostat on a TS-engine? (Stock Motronic) Normal operating temperature is 80°C, I bought a BMW thermostat (following Steck's website), but in practice it gets too hot (85°C). I had a picture here of the installation, but my post...
  3. Thermostat temp question

    Spider - 105 & 115 Series (1966-1994)

  6. Stripped threads on thermostat bleed hole

    164 & 168 (1991-1995)
    A few days ago I was tightening the air bleed bolt on the thermostat housing just a little bit more to stop leaking and... stripped the threads! I needed the car right then so I just screwed on a slightly wider M10 bolt in the hole (tapped itself) and that kept it from leaking Considered...
  7. Should I suspect a bad thermosat?

    Spider - 105 & 115 Series (1966-1994)
    89 Alfa Spider Veloce. My temp gauge reads about 120-130 Degrees. Someone told me it should be running at 175 degrees and I need to replace the thermosat. Do I need to replace the thermostat? :confused:
