Hi All,
I'm building a 914-4, 1975 1.8L Big Bore, 2056cc. I just took apart a different 914-4 1972 1.7L, and the FANs are different. See the photos:
This is the item I need help on.
1) The FAN I took off the 1972 1.7 is the older style, it matches the "Porsche 914 Cooling System" breakout found on several different websites. See below photo.
2) The above Cooling system/FAN breakdown shows a spacer (#3) under the FAN. I think that spacer is only for the old style FAN, see a photo of the older FAN below:
Old style FAN from a 1972 914-4
3) New style FAN (1.8L 1975) it could be off of a 1975 2.0L
Does anyone think the newer FAN needs the spacer?
I did see a couple posts where people had alignment issues between the FAN and Alternator. This spacer does push the FAN out 2mm.
Also, I can't find any drawings with the new FAN type. Could this FAN (new one) be from a Bus, VW, 912, Type 1, 2, or 3 engine etc...?
After writing this post and doing a dry fit of the spacer on both FANs, I'm leaning towards PUTTING THE SPACER ON the newer FAN.
It looks like it is needed for clearance and/or structural integrity between the FAN and the Engine Fan Hub. The newer FAN did not come with a spacer!
Thx -Monte |

Thx Ray,
That's great info, i figured that spacer is important. I need to get another one for my other engine (1.8L) when i start the rebuild of it. I found one for $25 on ebay, that's a rip off. I'm going to keep looking for one. I found another one for $5.25, but they said they were out of them at the moment.
Thx again Ray.
