Does engine cooling matter too much?

[Silver Arrow]

Engine cooling down in 18th, get to Zandvoort (2024 season) and I’ve been fine so far. Should I worry about it?

it comes in handy on those hot tracks, especially if you like to overfuel and push. but imo it's one of the least important things to focus on. i still try to keep it fairly decent so i can push without going into the red on engine temps. you probably know running the engine in the red zone cripples your engines very quickly.

Ah okay, thanks.

I'm not sure how much it matters. But I have noticed my Mercedes PT have been in the red for temp even without pushing much most of the races. I chose the mercedes drivetrain for my custom team since my car would be crap and the Merc was pretty reliable.
If my cooling is much better at end of year I might go for Ferrari next season. But Ferrari has much worse reliability.

Personally, I go for Mercedes in most playthroughs, since I am TERRIBLE at keeping my engines, ERS and gearbox above 40% wear. And for everything else that happens quicker. Also, the Mercedes engine is just more reliable.

well when in race and you look at the schematics (Lowest driver tab) and your engine temps are in the red zone depends on engine tolerance and upgrades specs, but over 120 degrees is usually in the red, means that you are wearing the engine out faster, as well as i believe having more chance of it failing..of course that will be offset by improved lap times, up to a point and dependant on the track.

The more worn an engine is the the higher the relative engine temperature, which means they (worn engine) will wear out at a faster rate than a new engine , unless you lower the setting and yeah as i am sure you know, it's also fuel consumption.

and cooling directly effects this to make it more manageable.

Yes, but we are wondering how much of a difference it makes. How much temp differnce will we see with a 10% increase in engine cooling on parts. will it drop several degrees under same conditions or is it barely noticable?

Right, well linear increase, with age, is how it appears to me, ie the older the engine the hotter it will run for the same power setting, so new engine will be at it's coolest therefore lowest rate of wear,and it will progressively wear out faster from there, that's why there is good reasons to lower the engine, but pushing will improve relative pace, so it's a balancing act..

if temps rise above 120-125 there's high risk of issues rising even if engine is relativeley fresh. also degradation of engine is increased if it's overheated. i usually try to maintain temps below 115C

That's not really what we are wondering about. Rather how important it is to use development (sliders) into engine cooling. How much difference do you see from lets say 10% parts improvement into engine cooling? Does it lower temps enough to be worth it?

If you have lets say 100% PT condition, on a certain track, lets say Silverstone at airtemp 28 degrees C.
How much difference is it in PT temps from an average 50% engine cooling on parts to an average of 60% cooling on parts. with all other factors equal.

In other words. Is putting development sliders into cooling really worth it or is it better spent on other sliders? How much will that lower temps. Just a tiny fraction or significant?
