Modular Engine Cooling

[Sir Crash A Lot]

I am struggeling to cool my 7 cylinder 3x3. The engine is running at 12 rps maximum and i am using the mid sized heat exchangers. One separate for each manifold (7) with a closed fresh water loop with a large fluid pump. Sea water side allso has a closed loop with a large fluid pump for each heat exchanger. Fluid pressure on the sea water side is about 24, but i really struggle to get more than a weak 4-6 on the fresh water side, given enough time the engine will overheat. I am running out of ideas here, any help would be appreciated.

Try using 2 small pumps around a 3x3 or 5x5 radiator instead for your cooling loops.
One per cyl is sufficient.

I ran a 20 cylinder 5x5 modular engine this way.

You should be using multiple loops, each with a 5x5 radiator and 2 small fluid pumps. 2 loops per cylinder should work, although it depends on how much power you are making (RPM and throttle.)
One other thing to note is that there is a bug with the flow of coolant throughout multiple loops, but if you de-load (tp away and back again) your vehicle when it loads in it fixes it.

Modular engine cooling is based on load and fuel input, not so much on rps. If you can use gears and run the engine at higher rps with less load, you will burn a bit more fuel, but have less issues with cooling. ! 5x5 rad for every 3 cylinders is about the minimum you want to go. You can get away with less but need to run at really low throttle setting.

I am using the 5x5 Liquid heat exchanger, 1 for each cylinder. I will try a different gearing, i try to make it around 12-15rps due to the more realistic engine sound, but i guess i will have to do some experimenting.

i now have 1 5x5 per each cylinder with separe loops of cooling water, and i have tried multiple gearing and power outputs, and theres not one single sign of improvement, however i am reading on the Stormworks discord that cooling for modular engines are broken for a lot of people right now.

Make sure you have a pump for input and output, and check the coolant flow through the radiator. (Should be above 60 liters/second.) Like i said previously, if it appears to be jittering, I would suggest teleporting over 5km away to unload the vehicle, then back again (should fix the problem.) I would also suggest 2+ loops per cylinder, although i hardly use 3x3 engines and may be incorrect (I'm assuming this is for a boat?)
Also do note that cooling becomes worse the more south you go.

I indeed have pumps for in and out on all places, the flow rate is 61l/s steady, however the pressure on the fresh water side is still quite low and fluctuating. Having tested with different pumps and amounts. Yes, it is for a ship.

You should also be using radiators, they cool better and take up less space/electricity.

Make sure your pipes are connected Manifod B>Heatexchanger B in>Heatexchanger B out>Manifod A. With at least 1 pump per system and make sure the pump is pumping the correct way. Heat exchanger out>pump in> pump out> manifod A

Are your saltwater outflows above the waterline? Also getting your ros down will help

[Sir Crash A Lot]

I am slowly getting the results i want, i had to add a much more pumps to the system and i indeed moved the SW outlet ports up above the water line, still some fine tuning to be made, but now i am on the right track, thanks a lot !
