Engine Oil Temps High

Rap,
I am sure Ferrari would not have spent the money to put the fan on the oil cooler unless it was necessary.

Might try fixing that and see if your oil temps come down a bit.

I can hear when my oil cooler fan kicks on, especially with the top down, and it does so whenever I am really running her up the RPM scale.

220..?!! oh lord that is high! Mine came sporadically close to 220 last year in Italy. I knew then I needed to change my radiator. With the new radiator it does not come over 202 anymore even when it is bloody hot outside and driving traffic jams. My oil fan cooler kicks in rarely nowadays.

I rather change my radiator the my fan to be honest. But like Alden said, it is on it for a reason.

 

Check your engine ground strap.

Mine had oil interfering with the continuity which caused the oil temp guage to run high. It was odd because my coolant was normal and new something was off. After cleaning it went back to normal.

Just my past experience.

 

I took this photo 25 minutes ago, both the water and oil cooler fans were blowing. The water temperature is approx. 90 Celcius or 194 Fahrenheit, the oil temperature is approx 75 Celcius or 167 Fahrenheit. It looks like your reading is a bit high.

Ferrari started putting on oil cooler fans from the 3.2 model on.

My qv has only high temp after repeatidly accelerating/braking.
But the temp cools down to normal directly after my fooling around.

Fix the fan and your oil will run cooler.

 

230F? Not a problem for the oil or lubrication - no harm would come from that oil temperature.

First suspicion if this is higher than 'normal' - get the electrics checked - sending unit, gauge, ground, as suggested.

Even then - I'd consider 250F to be the upper operating limit for conventional mineral oil. For synthetic oil, it's good to 270F before I'd worry.

On the other hand, 160F or 170F? Way too low for an operating temperature, I'd worry far more about 170F than 230F. At 170F, the oil viscosity is still too high, it's keeping the engine components temperatures lower than their design operating temp (from a thermal expansion viewpoint), and it won't be properly boiling off any accumulated condensation and moisture. I won't even use full throttle on an engine with oil temp below 190F, because it's not fully warmed up at less than that.

 

Gordon- Absolutely correct. 230 F would definitely be an issue for water temperature, but not in the slightest for oil temperature. That temperature works great for cooking off water, gasoline, and anything else that might be in the oil that is not desired. According to the OM for the 3.2 Mondial, if she gets up to 266 degrees, then you should start to see what is wrong.

 

Sorry, I was having the water temp in my mind. Then you have an issue. on average I have 215 on the oil temp gauge and 200 on the water one. Close to Jeka's pic.

The oil fan is definitely there to help suck in air to keep the oil radiator cooler. This is really noticeable at slow speed and stop and go traffic when there is little airflow through your side grill.

Driving in LA traffic stop and go traffic in the summer time I can see when the fan is kicking on and off.

Take a look at some of the newer super cars and they have fans and radiators for oil , brake, trans and of course coolant.

 

Nowadays, the multigrade synthetic oils are designed to have perfect lubrication in a wide range of working temperatures.
I'ld worry more on the coolant temp than the oil temp. Too low coolant temperature: all different metals are still expanding to working temp, so gentle on the trottle. If coolant working temp is reached (90°C), you can step on it, even of oil temperature is still low-ish (from 50°C and up)

 

I thought the oil temperature was an indicator that the entire engine was warmed up and good to go. The coolant temp comes up so quick, and it takes a long time for the oil temp to come up, I always wait until the oil temp comes up a little bit before going above 3K and then go gently until it comes up a bit more to 4K and then once it's in the normal range can do what you want ??

If water temp is at working temperature: 90°C,
oil temp will allready be at 50°C

If water working temperature is fully reached you can allready play around.

I tend to keep the engine under 3k rpm when cold, but sometimes a peak to 4K.
When working temp of water is reached I play around untill 6k rpm.
When I practiced at least 20kms I go to redline. (But redline is no must to enjoy her to the max) And when I'm touching redline during numerous heavy accelerations, my oil temp goes to 100-110°C. I give her afterwards some time to cool down a bit in constant velocity stretch (70 to 140 km/h)


These engines are bullitproof!

 

Hello original poster, we would like to "solve" this for you. What caused you to change the oil cooler?
Are you certain the fan doesn't work? Or is it possible you haven't noticed?
Is you current gauge reading very different than it used to be?

If so, what occurred prior to the increase in temp?

I am sure you have already checked the oil level?

As stated earlier, 230F is not cause for alarm in itself, even if the temp approaches that number fairly quick ( many variables here ) It will not continue to heat up in a linear fashion. At a certain point, it will stabilize and cease to increase.

Based on your answers, this may be normal. However, many responses already hit on good courses of action.

If you still have problems after getting the fan working, there is an uprated oil cooler available to give greater cooling. An after market firm here in the uk sell them.
You need to bear in mind that without the fan you are just cooking the oil when you slow down, when in fact the fan should be getting rid of the heat when the engine load is less.

 

At what Temp. does your Oil Cooler kick in? I jumped mine, and it works, but have yet to hear it run on its own. Even with the high air temps here in So, Mississippi, the oil temps never seem to get above 220-230F. Might be due to the air flow coming in on all our open roads and few traffic snarls.

 

Just a tad under 195 water and 210 oil on my Euro QV (no oil cooler) not matter what I do here in HK (highway/traffic jam/mountain roads), at 86/very humid outside. All systems OEM.

 

... should read (no oil cooler FAN)

 

If the oil cooler is orginal, it might be an idea to chemically clean it internally.

 

My 84 QV (US Model) has a Ferrari oil cooler fan which seems original. Maybe in US but not Euro models?
