308 GTS/B heater blower mounts are junk

I know this is a very old thread but I just discovered my 85 has the same problem. I just found both fans lying on their side. If anyone has a template out there it would be very appreciated. On another note, the whole reason I started looking around is that I am not getting any heat out of either heater core. The hoses barely get warm. Is it possible there is an air lock or plugged up hose. Any advice appreciated.

 

In a different 308 fan blower thread ( 308QV Heater Blower(s) | FerrariChat ) I posted about my fix. I hadn't actually seen this thread, but came up with a similar mounting bracket with multiple mounting points onto the fan housing:

In that thread, Brian/Rifledriver indicated it's a very common problem. Previously in this thread (post #20 in 2009), Newman suggested that a fix like this was a hack fix that would lower the value of a 308... My compromise suggestion would be that if concours original condition is a requirement before eventually selling a 308, then buy new pristine heater blower fans and keep them in the box to be fitted just before putting the car up for sale. Meanwhile, do the reinforced fix I and others have done and enjoy a worry free no breakage fan mount experience

Thanks for the pictures. I can probably make something similar that will work I'm not interested in keeping the car in concours condition so this is a great fix. Replacing the fans is over $300 each. Anyhow thank you

 

Here’s what I did after I also discovered both fans resting on the front spoiler. Has worked so far. I also replaced the air hoses, cleaned the filter boxes at the other end of the air hoses, and replaced the small filters with some filter material I found at Home Depot. The small filters were extremely dirty.

Nice to see this thread still active 16yrs later. Hopefully it has helped some people out. The only design I don't love is the pop rivet mounting, unless it has a washer on the backside of each rivet(even then, I don't love it). Plastic and rivets are a bad idea. Old plastic and rivets is an even worse idea. Typical plastic(PVC/ABS) either flows or cracks when under a constant load. The nylon locking nuts are great because even if the plastic underneath changes dimensions, they will not loosen.

My list of easily fixable 308 issues completed over the years:
slow window electric setup
gts roof latches that rip the interior fabric
gts roof cover
exhaust sniffer tubes
catalytic air pump
USA bumper protrusions
poor headlight output
poor keylock designs on doors and louvers
the factory warp in center console between shifter and clock
spare tire fiberglass riveted in place(converted to threads screws)
another dozen I can't think of at the moment
