Think the later cars moved to 88 degC and I used one on my car for a while. Mine is a very early 1990 1.4 and has an alloy housing for the thermostat. It's possible your car has a plastic housing so you'd need to check compatibility of the thermostat fitting. You could also ask at DMGRS as they supply thermostats such as https://www.dmgrs.co.uk/products/k-seri ... a111&_ss=r. Think there is also a 74/75 degC thermostat for racing/track use. The DMGRS guys could advise what's available for your car, but it should be similar to most other 1.4 K-series engines. The 82 degC thermostat was what had been originally fitted to my engine in 1990, so I went back to that. Really want to avoid any overheating with the K-Series. In this discussion about thermostats, you did originally say that the temperature gauge looked normal when driving, at around the middle of the gauge. If this stays constant as demand for different amounts of power, using the heater, and when idling afterwards (when the radiator fan should switch on) that would seem to indicate the thermostat and cooling system is working correctly.
