Not too hot, the gas engines run much hotter then a diesel.
Also at 15psi pressure in the cooling system, it can go up to 230° before boiling, each pound of pressure adds 1 degree to the boiling point. That is also tested at the thermostat housing on the outlet side of the engine, where the coolant is the hottest.
