What engine temp are you normally around?
 

Hey guys,

For some reason my car was acting a little strange today. First after my friend was driving it a little aggressively, we shut it off for a few minutes and then got back in the car. When he turned it on the car stuttered a bit and for a few seconds it had trouble getting the RPMs up. Like it was about to stall. I don't know if he let the clutch out at a bad time or something, but I couldn't replicate it anymore. The other thing I noticed was that the car was running a little hotter than usual. Usually the car remains just under the 200 degree mark. Today (72* Outside temp) it remained above it all afternoon. Driving it a little harder I could get it up to two ticks over 200*. I started driving it normally, but the temp would not come down under 200. It sat around one click over 200. I guess I haven't driven it aggressively for extended periods of time. When I came home I let it sit with the hood open for a couple of minutes and the temperature just wouldn't come down from a tick over 200. I turned it off for a min and then back on and the temp sat just under 200..I watched it for a while at idle and revved it up a little and it didn't really move from just under 200.

So I thought the normal temperature was around a tick under 200*. What are you guys getting under normal driving conditions? How about when you drive it more aggressively on the street? It just seems a little weird that it would do that stuttering thing and then the temps sit a little higher.. Maybe I'm just being paranoid, but it doesn't hurt to ask.

My temps are usually 200 after it "warms up". It gets to 220 after long drives on the highway. I've gotten it up to 230 after spirited driving and then it cools and stays around 220.

Cool thats what I wanted to hear.

Temps
 

I noticed the same thing when driving very aggressive, the temp would climb to 200, used to all my other vehicles being in the 165 to 185 range. When doing about 120 and coming down it will reach about 210 but never higher, thinking summertime is going to suck for speeding if this car overheats...

D

OK perfect, I am glad I'm within the normal range...

Oh mama good thread... just what i needed.

I changed oil on Saturday, went full synthetic Mobile 1, and all of the sudden I see 200 on the oil temp gauge, jumps up to about 230, once i get going and just stays there, then kinda goes down, at first i thought it was a lack of oil, i guess now its just how the car is.


water temp is the same though, it stays 1 click under the medium.

^^ Yup

Maybe a fan mod would help keep the temps down a bit? That or a 180 degree Tstat? I'm not sure if it will help the Z much, but 200+ seems a little high. I've had performance cars of all kinds and they never hovered above 200 unless they were driven really hard.

yes, that is what is worrying me, one of our Daytona prototypes hit 250 once, and it began melting fuel lines, hell I am only 20F off that mark.

but for some reason only 3 of us in here seem to see this problem.

Well this is the first year of the new 370, so this may be a bug that may pop up in more and more of them as time moves forward. Another idea is that you can purchase an oil cooler kit, which should definitely help. The only downside is that it is not going to be an inexpensive mod.

but i should not need to buy extra crap to fix a problem that Nissan should have solved.

my biggest worry, was this just happened when i changed the oil at 1,300 miles to mobile one. or maybe it always ran this high i just never noticed it.

but the water temp is ok, then again that is what the radiator is for.

my water temp is always a couple dots below half, but my oil temps when i drive on the highway are between 200-220 here in hot florida

^^^ ok so you are in my same boat then, and the other floridian is too. Now we are kinda getting somewhere with this.

I called my nissan dealership, and asked, but its like talking to a starfish about quantum mechanics.

they have no idea, according to them that is normal operating temps for a car, if the problem gets worse call them.

so essentially if my block becomes one solid piece of metal, then they will try and answer my question.

^^haha ya. the car seems fine. Ive run it hard several times against friends, but the temp never passed the 220. It just looks like the needle on the gauge looks high becuase of the way the gauge is set up. I'll let u know when my block is a solid piece! haha...well thats actually not gonna be funny.

Mine did the same thing, several times now, its after driving a bit and then getting back in, it stutters and feels like it's going to stall. :mad:
When I had my Nismo exhaust installed I had them check this, of course they didn't find anything wrong.
RCZ: Do you know what brand of gas you were running? I know for sure I had just filled up the night before with Shell 91Oct. And Im almost sure that was what I was using the last time it happened.
Could it be a detergent or additive in the fuel?

Oil temp is between 180 - 220 range, usually hovers around 200. I hate to see what it's going to be like in mid summer when it's 90-100 degrees out side.

As a side note, I just changed the oil to Royal Purple synthetic this last weekend, it did nothing to lower the oil temp, but Im certain the car feels quicker, it seams to rev faster and have more torque, it could be my imagination but I could swear the car gained 10+ HP.

Looks like we are in need of some after market oil cooler. What were the 350z oil temps running at, were they similar??
