Hi, does anyone know where I could obtain a known working used or new radiator fan switch for an 83 1.5 Sprint please ? I've tried Justsuds but they are out of stock and don't know when more will come in.
try a local independant parts supplier, we have PARTCO up here, sure they are nationwide. anything similar should be able to help, or try a radiator specialist who will also be happy to help
surprising how many smaller service type items are still readily available as they are maybe carried over to newer models, like the 33 or maybe even the 145's with the boxer engine?
worth trying your local industrial estate for a suitable supplier
33 thermoswitches have an identical mechanical interface and are specified to switch at the same temperature as the 'Sud and Sprint, but they have a different electrical connector. I replaced my 'Sud thermoswitch and all my motor factors had was the 33 part. I couldn't be bothered to change the connector so I cut back the plastic shroud around the terminals and soldered spades to them. It's been working faultlessly for 2 years now.
I agree - I had the prospect of a 20 mile journey when my thermo switch failed. I blagged a couple of paperclips to temporarily short the switch terminals, which had the fans running all the time, but at least I was able to give the car a darned good thrashing
Ok, quick update. Finally obtained a new thermo switch from ebay but wanted to test it before fitting. At first it seemed faulty as despite placing in just boiled water from the kettle a meter showed the switch as still being open. I took some advice from a friend and redid the test by placing the switch in a shallow pan of water on a hot stove. This time it closed.
I've now fitted it but still the fan will not come on despite the car idling for up to 15 minutes with the temp guage rising ro a steady 175F. However, I've since realised this converts to only 80 C so still below the level at which the fan should operate. http://www.alfaowner.com/Forum/images/smilies/redface.gif
So my question now is, is the car running too cool in which case should I suspect the thermostat ? Or is this normal when the outside temp is mid teens celcius at best ?
Finally, is a temp guage reading in fahrenheit normal for my UK 83 Sprint Green Cloverleaf ?
It doesn't sound like its running too cool to me, but the only way to find out for sure is to actually give the car a good run. Even then I wouldn't expect the fan to come on unless you were stuck in traffic for some time. The main thing is to observe the steady-state running temperature. After correcting for my non-standard calibration, my boxer runs at a steady 78°C most of the time. I actually drove the 120 miles to MITCAR at a steady 60-65 mph and the fan didn't come on once
A farenheit temperature guage on any Italian car sounds very strange indeed for a UK car...
Thanks Lauren, sounds like its all ok then as although I havn't taken her for a long drive (yet )the temp does seem to stay steady at around 175. Maybe the age of the car is making me think there should be more faults then there actually are !
