    I have an '85 308 GTSi QV and need to upgrade my cooling system for the hot AZ days. I've been fighting and chasing overheating issues for years. I remember seeing a radiator with 2 fans and fan shroud package but can't find it anymore. I thought it was Nick Forza who sold it, but he only sells the Wizard Cooling radiator and upgraded water pump. I supposed that could be enough or at least better than what I currently have. Anyone seen a radiator for the 308 with fan shroud?

    There isn't any room for one. To put a shroud on will mean moving the radiator forward and eliminating the condenser and I don't see that being a Saturday afternoon project, or modifying your spare tire well buy cutting it off in the front which will give you another problem with the spare.

    Why not look at changing out the fan units for the modern motor 10 blade units sold on eBay?

    That's what I have now. No shroud, though. Can't do it in there

    Those fans have built in shrouds, and I would like to think they will push much more air. Especially as I bought a set, not yet installed.;)

    78 GTS US. I installed 12" after market fans in mine a while ago. While I think they help they are not the end all. I rebuilt my stock fans so they were working like new and had the radiator professorially cleaned (not re-cored) but it still ran hotter than I like on very hot So Cal days in stop and go traffic. I would get up to about 210 - 215 degrees in traffic then drop back to about 185 if I could drive 30 mhp for a while. The 12" inch fans are a mother to install. I had to remove the fan guard to get them to fit. The temp will still get above 200 but its better. The stock fans draw a bunch of amps and the stock fuses would really get hot. Not so much with the after market fans although the fuses would still get warm. I just finished building and installing a new fuse block that uses modern blade fuses. Not sure but the aftermarket fans seem to run a little faster if so probably due to less resistance in the fuse block.
    I attached some pics of how I installed mine. BTW I tried 10" aftermarket fans and they didn't cool as well as the stock ones which are about 12".
    I use the stock fan brackets and used deck drains with L brackets to attach them.

    i know this may sound silly but propping the bonnet open helps even if off the catch

    Doesn't sound silly at all. The airflow path aft of the radiator is not ideal, which is likely why Ferrari added the louvers to the bonnet on the QV cars.

    Did you try replacing the temp sensor for the fan with a lower temp setting ?

    Yep. The radiator top is sealed to the hood and the hood is sealed to the spare tire enclosure. I've considered opening up the bottom panel for more flow.

    It has a 185 degree temp sensor for the fans. I had a 185 degree thermostat in it but acted strange per Birdmans article. I purchased three of them from different suppliers and all three were the smaller diameter so I put the stock (original) one back in.

    I removed my spare tire tub and had a shroud made so it would fit two puller fans. Really helped with the cooling.

    Cooling systems were general pretty marginally designed prior to about the 90s. I remember as a kid in the 70s in upstate NY anytime there was a traffic jam there were cars pulled off the road overheated, we called it "lets try to spot the cars with AC"....and that was upstate NY where it never gets above 90F outside. Classic cars are what they are so compromises need to be made to enjoy them. Its either keep it original and watch when and where you drive or modify stuff. I have a large aluminum radiator with and 18" fan, the overheating that was horrible when I got the car is not a thing anymore even with the stupid high hp engine setups I've run over the years, but that is driving in PA heat not AZ heat so I don't know what the extra 20F degrees and beating sun would do, nothing good I assume. There are also bolt-in alum radiator options I'm told help an awful lot.
