Which specification is good for a Toyota duet 1.3 L engine. 0.9 bar or 1.1 bar?

1.1
Thank you. What informs the choice?

It should be 1.1
0.9 is for bigger capacity radiators. if you use it on such small radiators the system will run at low temp and accumulate heat in the wrong places. fan operation might also be erratic. the system will also produce steam leading to quick loss of coolant.
Helpful comments. Thank you. I couldn’t trace the car owner’s manual

Check Impala Spares, they have original and aftermarket good quality radiator caps, I bought one for a Noah last month at 1750bob for original Toyota part , aftermarket they had quoted 500bob, just give them the chassis number for your car and they sell you the right part that you need.
Most Toyota’s use the 1.1 bar cap, 0.9bar is common in Nissans.
just check what manufacturer recommends and use that
Even 0.9 is common in toyota’s. It’s just dependent on the size of the radiator system. Like most 1.6l and above will have a 0.9 cap. Forced induction engines will also have high pressure cap because of additional heat production.
This logic is quite flawed!
Best follow manufacturer specification. The pressure rating shows the highest pressure the water will be held at before pushing through to the reservoir. Often, the higher the pressure, the better…especially for high compression engine. Turbocharged EJs and high compression NA engines such as VQ25HR (Nissan Skyline) use 1.4 bar despite having large radiators.
Its the same concept. Nothing wrong with what I said. NA engines with large radiator will use lower pressure cap and those with small radiator will use high pressure cap normally. As I noted in the post above yours, engines producing more heat will have a higher pressure cap. What I explained about using lower pressure cap than normal is exactly what happens with his car.
Take it easy with the animals in here. They’re quite slow in everything.
