Ferrari Mailing List: Re: 512 TR cooling fans

[Peter Rychel (dino308gt4]

Hmmm, I can hear the radiator fans come on and off while I'm driving my 308 (not just at rest). As much as I can believe the gauge on the dash, the needle stays rock steady just below the 90*C (195*F) mark. I've mentioned before I've had the rad re-cored and have the proper thermostat/rad fan thermoswitch installed.

As a matter of fact, the worst area of my fuse boxes were the rad fan circuits. The clear boot protecting the quick connect on the wire was melted. I've since soldered all of the rivets and buss bars and it's made a huge difference to reducing the temperature of all of the connections at the fuse boxes. I've experimented  with success so far of an aftermarket ATC-type fuse box to replace these old ones and they were stone-cold to the touch after a long drive and quick track run this past weekend with outside temps touching 90*F.

Here is the bottom line the last real radiator that Ferraris had was in the 308/328

The rest of them are junk

If you own any car other than those I mentioned you are sitting on a near term

Chernobyl event one day with your car 

For TR owners they need it more than most, the heat they put out is extreme 

I was lucky that I routinely check and flush my radiators 

But that didn't matter because they are cheaply made 

And I had a failure early on and changed out one 

But now that after market aluminum radii are available why would you take the chance?

Thanks for the diagnosing tips. It's surprising they use such high amp fuses even with these modern fans. Are they still made by Spal?

That's good to hear the radiators are capable for handling the heat on their own... Wanna try without any fans? <OutlookEmoji-😉.png>

Well it finally happened after 130K I had a cooling fan go out on the  passenger side

Here are my tips for making sure it’s the fan motor and not something else

 

Go to the fuse relay box and jump the relay

You need to jump terminals #30 (hot always) and # 87 which is the lower one on the relay

If the fan doesn’t run

Check your fuses # 6/7 respectively

I replace both of the fuses with new ones and they are  25 amp fuses!

Not done yet

Un plug the lead into the fan motor and get a test light and jump the relay again

If the light comes on then you know it’s the fan for sure!

 

Going to buy two new fans and aftermarket aluminum radiators as well and install them this fall

That’s it

Even with the one fan motor out the temp stayed around 210 which surprised me
