Pointy thing should be in the middle after about 3/5 mins of driving. (depending on how you drive.)

Should NEVER go above middle. If it does the damage is already done.

Just remember to test, test and tripple test the fan.

Sound advice there, if the gauge doesn't reach the middle then it could be a simple stat problem. Still an involved job but well worth it.

The temperature gauge is of little real value. It's designed to maintain a false sense of security, i.e. it shouldn't vary from 'normal' (the 9 o'clock position). If it does, it's probably more serious that you realise, so act immediately.

As for your question, the optimum running temperature is in the range 95-100C. Most 75/ZT petrol engines in their standard condition seem to run at 97+/-2C.

You can get an accurate picture of what's going on with your engine temperature by using the IKP diagnostic mode. This is described in this thread: http://www.the75andztclub.co.uk/foru...or+temperature
