At the risk of sounding like a broken record I'd like to point out there is a search feature in the upper right hand corner of every forum page (which I just used) and quickly found this: https://www.toyotavantech.com/forum/...ernator+shield
I would highly recommend repairing the leaks for obvious reasons, but if you use a shield, keep in mind the main alternator output stud is up high on the back of the alternator and you could potentially have a fire hazard and/or a melt-down issue if anything metallic comes in contact with it (just make sure there's good separation).
