Hello

I'd suggest draining the coolant and then using a pressure tester to put 15 psi of air pressure into the cooling jacket and remove the oil filler cap and listen for any hissing noises

The other thing to try is a head gasket / block test kit as these take a coolant sample and analyse it for any signs of combustion gas - if present this would indicate the head gasket is on its way out
