Ferrari Mailing List: Re: 512 TR cooling fans

[John Ashburne (jashburne]

I would agree and I attribute the delta between the two readings to the points where the temps are measured.

Oil and coolant temps should marry up under normal circumstances 

There are times when coolant will rise above the oil temp but it shouldn't be by much

On my 400i, normal water temp was 90 C and I liked to see oil temp just above 100 C to make sure any moisture in oil boiled off. 

Engine very happy that way!

Yes you are correct

With around 40 mph the temp will stay below the threshold of the thermostat turning on the fans

I plan to put an override switch in to turn my fans on early since I frequently get caught in traffic

I have done this on my bike and it really helps keep the temps down

You should be reading temps around 180 on the gauge which should mirror the oil temp

Only in hot traffic will you see a slight rise to around 210 or so

At least that’s been my experience

As long as it's moving, the cooling fans in my '87 TR do not come on even on hot days. They may engage for a bit when parking. Very efficient cooling system.

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
