I may have a look at the screws on the filter box today to check the state of play for air filter change... I'm not doing the thermostat change myself, a garage is, so I don't want to ask the mechanic to include the filter change, that may cost me loads in unexpected labour time if the screws are seized on, which is what nearly always happens with Alfas and local garage mechanics. (mechanic sucks air through teeth..."its been a bit of problem, er..." ect, ect...)
I loved my old Suds and Sprint (except all the sundays spent banging filler into the never ending rust spots!) Easy to work on great to drive and of course beautiful looking cars too!
