Any creative idéas of how to get it out ?

There are several ways to get that bolt out. You can weld another bolt to it and use a wrench on the new hex bolt head but if you have no welder; a small Stilson wrench or a small pair of vice grips may be able to remove it. A stud remover socket wrench may also work.

Cutting or grinding off the head then weld a nut onto the stud when you pull the water pump off.

I was actually thinking of welding a nut to the head or take the T-50 bit and weld it to the screw.

Is there any things that could generate problems when welding on the engine? Sensors, ECM etc ?

You need to use some common sense, but in general you won’t create problems welding on the engine if you imagine the path of the current and avoid having the current pass through bearings or things like that.

I think that grounding to the engine block, timing chain cover, or gearbox casing could all be good choices.

That could work if the bolt isn’t too stuck. You may lose some of the heat transfer from the stud to the threads, which is useful for breaking free stuck bolts. As long as the battery is disconnected, I’ve never had issues with welding on the engine block.

If you decide to weld a part on the engine I would disconnect the battery cable and run a chain placed on the ground cable to the floor We've welded exhaust systems and brackets while everything was connected without any problems but in theory electronic pulses under certain rare conditions have the potential to damage the ECM .

DIsconnect the battery and unplug the ECM to be safe.
