Re: Replacement Windscreen Washer Cap for 147
Welcome to AO. Hope it makes your ownership experience an even more happy one.
You need 46744602 from Alfa or Fiat dealer, price approx £1.37 (2003 prices).
Will they have it in stock? Not likely but if there's one at Warrington (the parts distribution place), you'll have it in a couple of days or so. Also found on some Lancias (not much use) and Fiat Doblo (model 2000 onwards) so might be easier to get than I thought.
If you like the hands-on approach (and even if you don't) a parts CD/DVD called ePER is really useful - they are all over the place on eBay. Don't pay more than a fiver for a DVD.
