Q:
What do you think, do old cars run hotter than new cars or do new cars run hotter than old cars.. say does a 240z run hotter than a 350z? thanks for input

A:
This isn't a matter of opinion. Newer engines can run much cooler than older engines because of much better cooling design and technology.

A:
It's the other way around, newer engines run hotter than older engines. It's for emissions and all that other BS.

i know its not a matter of opinion...ooooooooooo one says old another says new, i say new cause it takes a while for a old car to get to regular operating tempature where a new car gets to normal operating tempature much quicker

It depends. Old cars can run hot, old cars can run cold.
A:
I just measured my 280z after a spirited run:
Temp at top of block and bottom of head between plugs was 87-90°C
Temp at each tube of header where it exits head was 114°C except for 4 &5 where it was 130°C
Water temp in rad cap area was 65°C

Ok, now we need a 350Z measurement.

Stock oil temps?
Stock water temps?
Stock CHT temps?
Stock EGT temps?
Stock what?
A:
Datto do you at least have some chrome or racing stripes? If you don't you're missing out on a lot of power.

They are both like woman......sometimes they run hot & other times they are cold as ice.
This whole world smells bad, I'd buy another if I had
back what I paid for another mother@#$%@# in a motorcade
A:
Datto240z, YOU asked for input. Give us a parameter and you'll get input you can use (otherwise accept random input).
A:
All engines will run hot if you rev them high enough.

Fine, to answer your question...it depends.
You will find new engine X runs hotter than old engine Y
and you will find new engine Y runs hotter than old engine X
Far too broad of a question.

Or do Nissan engines run hotter than Ford engines?
Do new V8's run cooler than old 4 cylinder engines?
All depends...

this is pointless you guys will never get anywhere

I think that is Hybrid and I's point exactly.

my 240z gets hotter, but the question is.. should it?

"What do you think, do old cars run hotter than new cars or do new cars run hotter than old cars.."
Well, without a doubt, the NEW cars are designed to RUN HOTTER than older vehicles.
One needs only to look at a 1956 Small Block Chevy, and a 1996 Small Block Chevy. Apples to Apples.
1956: Carburetted, ran a 165 degree thermostat, and had absolutely no pollution control other than possibly a road draft tube.
1996: Pollution Controlled, EFI engine getting much better fuel economy, more power, better torque, and running 190 thermostat, if not a 215 in some of the newest iterations.
It's not a matter of opinion, it's a fact. New cars run hotter than old ones, BY DESIGN.

finally! thx alot tony you cleared this one up

A:
Nope, the EGR in new cars is specifically designed to LOWER combustion temps. Beyond that, all bets are off when it comes to operational temperatures.
A:
I'm with Tony on this one....
In fact like said, better fuel economy in newer cars because of the way they're controlled..unless you can fool the computer system into a lower
temperature. Again, by design, if operating temp isn't achieved newer
engines will run in a "choke" mode causing alot of fuel consumption (ususally a higher idle)...so I've been told...and again why thermostats are sold from behind the counter compared to the way we picked our own from the shelf years back. Now you ask for a cooler one and the guy says "what vehicle" and responds "I don't have one listed for that"...some kind of option???
(now my old '66 Ford Must. with straight 6 ran cool and was a lousy winter vehicle to get heat out of...but was known for that too...I can remember
flushing out the heater core every couple of years just to convince myself it wasn't blocked)

Dude, you gotta be smoking Hash to think Combustion temperatures is what people are talking about here. Another attempt to mindlessly blather on in a contrarian viewpoint adding nothing the the discussion other than another useless post.
Even if COMBUSTION temperatures are lowered, the OPERATIONAL temperatures of engines BY DESIGN have RISEN since the 50's.
Adibiadic Efficiencies tell us that less power loss occurs at elvated engine operating temperatures. More fuel is converted to useable energy through decreased thermal rejection in the radiator.
Simple Engineering. And the answer to this question.
Feel Free to prattle on after munching another hoarde of brownies, but we all see your game. It really does get old.
In short:

If you are ONLT wanting to discuss WATER temps ONLY, those are set by cooling capacity and thermostats and nothing more. Throw a 160 thermostat in a new car it it will run all day at 160 no matter what the "design" intent was.
The question itself is so dumb as to only assume one parameter and I was trying to point that out. Many older engines ran close to boiling all the time.
A:
You obviously are the only one that thinks that way.
Everyone else saw the obvious question being asked, and answered it straightaway.
That is because they were intending to answer a question.
That is never your intent. Your intent is argument for the sake of argument.
Any idiot can ascertain his intentions through the post, and subsequent responses.
Your retorts are foolish in their obscurity, as if anybody here cares about the ebullient cooling of a Ford Model T.
That hasn't been standard in automotive design for.... aaaah, oh almost 90 years now.
Get with the program. You add nothing here, you come to only argue. You are worse than useless, you are a Troll. I only need to reference the closed thread on oil rebranding where you tried over and over to start a fight, and nobody was having it.
More than I see your bullsh*t for what it is: the demented ramblings of a hopelessly disturbed individual off his medications. Take your meds, come back to reality.
