Replacing alternator with magnussen SC in place.

[Ironchef]

Hi. Couldn’t find this issue. I have a 2020 tundra with a supercharger. Alternator seems to have crapped the bed. Wondering about the intricacies of swapping it given the new pulleys etc. I didn’t install it myself; I’m not quite that inclined.

The pulley on the alternator should be the same, it should be a direct swap.

It is probably also a good time to swap in a new belt. The belt should have a number on it if it isnt too worn, that is the part number and they are all the same across different brands. If it is too worn, you should call the supercharger kit manufacturer and ask them what belt it is.
