I was having issues with the thermostat on my 99 twin spark Spider to the point I bought a new thermostat. I took the car to hampshire at the weekend and now the thermostat appears to be working perfectly. Instead of dropping below 90 and going tepid the temperature gauge remains at 90 and the heat can be controlled now. Bizarre or just an Alfa???
Probably both. I thought my temp gauge had gone as the needle never moved but on advice from this site I got the thermostat changed and hey presto the gauge worked for a couple of weeks and stopped working again. Apparently thermostats go on a regular basis on Alfas. Don't know if mine has gone again or it's something else.
