Kurt, I can't believe you're saying that. How bad? Did the engine lock up or did you run the engine hot for a period of time without noticeing it? Exactly what happened. | ||

What happens when you overheat your car? I did that to my Mondial this weekend, and it's now at the dealership. I am awaiting their bad news. | ||

My 1986 3.2Qv Mondial runs at under 90 C on engine and transmission on open road with an outside ambient of about 26 C | ||

I just finished the conversion to Freon 134a in my 77 308. Before the A/C was fixed the car ran normally past the 1st notch or about 170 degrees. Only went to 190 when in traffic or after high rev running. I'm using 60-40 antifreeze mix. Now with the A/C blowing cold and in traffic it goes to 195 and stays there. No movement up and when I turn off the A/C it goes back to 170 and the fans turn off.So no problem here. The car runs better at 195 with cooler air coming into the carbs.Also fo each lb. on your Rad. cap you get 3 degrees over boiling in a closed system. So 12.8lb cap = 38 degrees + 212 = 250 Degrees before the water will boil.The book says max temp. can be 240 and no higher. So anywhere in the 190-210 is OK Steve | ||

Thanks for everyone's posts. My 90TR gets about the same range as what Billy and Michael mentioned. I always thought my car was running too hot, but looking at everyone's posts I feel more comfortable now  Just put water wetter in it, since I have heard some good things from people on this board. Thanks all for the feedback. My fan seems like it's always on around 195. My oil temp rarely reaches mid point area. I know that's normal now! James | ||

My cockpit gets hot. My favorite time to drive my car is around 6 pm with the top out. Nothing beats it on a sunny day. On a hot day around 3pm forget it. You get baked. My car is red/black so I don't like it sitting out letting my interior get beat on by the sun if I am just going to be at work all day. | ||

85 308GTS: I am still running a relatively thick antifreeze mixture with water (about 60% anti I would say). On hot days in NJ traffic my car will start to creep up and hit around 210 when standing still. Oil will go up to about 220. When I'm moving, even on the hottest days (mid nineties) my car wont go over 195-200 and oil hovers a little below 210. If I was to use water wetter and water that would knock my coolant temp down some I would say. I haven't really tried that trick with running a little higher rpms for a few minutes, but awhile ago I started thinking that concept and have been doing it for like maybe 10 seconds at a time in traffic. Does anyone else's cockpit area get hot? I think the air from the front compartment is making its way to the cockpit and it blows out hot air on my feet when I'm moving. | ||

Peter GT4, The TRs seem to runs like that (except for William's of course but his cars are doing things our cars never see -- his numbers are probably closer to Ferrari test track numbers). Its optimal highway happy zone is water 195 - 200 and oil 212. In that zone you can floor it everytime and she responds with a snap of the neck like nobody's business. | ||

Another trick in cooling that may seem counter intuitive is when in long traffic while in neutral bump your rpms up -- to about 2000 - 2300 -- it makes the coolant flow faster and cool the car better. I was told this by a Ferrari mechanic/afficinado. I was skeptical at first then tried it once and it worked. The higher rpms dropped my temps 5 - 7 degrees in about 3 minutes and I was at a standstill. My car has never been so hot that I have actually used it to cool the car though but at least its another option. | ||

Michael that is exactly what my car does. The oil temperature never goes above 21o degrees either. On the 355 it is the opposite. The oil is hotter than the water. I think it is due to the amount of oil (10 qts on the 355 as compared to 14 qts. on the TR). While I am driving it never passes 195 degrees. I initially thought that because all the air that was getting sucked up was other cars hot exhaust gases that also might contribute to high heat because if I leave it idle for a while it never passes 195. Thanks guys. | ||

My mech says the Italians like to run the cars hot to help with emmissions. I was seeing the oil at 270 on the track but since I removed the cat shes down to 250 | ||

Thats funny Michael(Man90tr) that your oil temp was lower than your coolant temp. From as much as I know oil should always be about 10 to 20° hotter than coolant. When I was stuck in heavy traffic once, I read coolant at around 210° and oil at around 240°. | ||

Normally it runs at about 80C as long as the car is moving, in traffic (there is a lot in London, UK)it slowly moves up to 90C when the fans cut in, the temp' then oscillates between about 80~90 as the fans cut in & out. It only goes above 90 if the fans don't work. The car runs a single turbo' so theres lots of heat soak if you've been running fast then grind to a stop! Last week-end I tested the fans as I was going to a car show & thought that there would be alot of "stop & go" traffic, they didn't work! It turned out to be just a poor connection on the temp sensor! Not all problems on the Ferrari cost alot to fix. | ||

It was a hot day yesterday and my TR did the exact same thing when I got stuck it traffic for 20 minutes. I get that also every so often in traffic when in Florida over the winter. I got 3/4 travel also-- like 215 - 220 on the water temp and it stablized there. Oil stablized at 210. I drove the car today for 1 hour nonstop - 3/4 on highway and 1/4 in city and it hit 195, fans came on and stayed there throughout city driving. Never once went above 195. I think it depends how hard you drive prior to the traffic. Each time this has happened I was playing in the high rpm range (5000 - 6000) for 20 plus miles then boom i hit traffic--- at that point is just one big heat sink with no airflow from movement. Temp then skyrockets. Unless your car does this all the time I wouldn't worry about it. | ||

The fans come on at 195 and the temp never goes above that. Only when the fans didn't work did it go above that. | ||

Tonight I was stuck in about an hours worth of traffic and my temperature gauge started to go up. It usually stays at 195 mark (half-way point) but tonight it crept up to the 3/4 mark not the red zone. Both fans were constantly working and the car did not overheat. It was just starting to worry me. Is this normal because the car was stationary or crawling uphill (I was stuck on a bridge). I have used that Redline Wetter Water but I would like to know if the same occurs with your cars. Any input would be appreciated. Thanks |
