Charcoal and Fan Delete

Post by Pescado »

Hey all,

While working on the car I've come across two ideas.

1. Can I get rid of the charcoal canister? No smog laws here.

2. Can I remove the fan from the fan housing and bolt it to the water pump pully...I figure this way it can't electrical fail plus lose a couple pounds plus more engine space...seems like a win but seeing as I don't see many set ups like this I'm a little skeptical.

Thanks.

1. You can, but it's not doing any harm being there and it doesn't affect performance. If you remove it, you open up some space as well. If it's working, it does minimize some of the gas smell in the engine compartment, and so I always just leave them.

2. That's kinda how the very early spiders were set up, through 1969 or so. The fan blades were on the end of the water pump shaft, and there was an electromagnet clutch to lock the blades to the shaft when the engine was too hot. Until that point, the fan just free-wheeled from air flow through the radiator. However, Fiat quickly abandoned this approach in 1970 or so and used an electric fan thereafter. A properly working electric fan really is the best solution for these cars. Minimal horsepower drain, doesn't put extra weight on the end of the water pump spindle, etc. One possible problem with your approach is that the fan blades would be too far from the radiator core, so they wouldn't pull air through the radiator very well.
