vr6 with 10w60

Hello! I intend to make an oil change with my Ford Galaxy VR6 Built. 99. Now I would like to know what the difference between 10w40 and 10w60 is and where the oil filter is located and where I get it. Since I have never done this before, I would still like to know what else to consider. Greeting Sascha [Transferred from motor talk from the topic ’10w40 or 10w60 Difference?’]
