i actually don't know wether or not an alt will void the warrenty. supposedly it's if you modify something with the engine or affects the engine or the tansmission.does a HO alt really void warranty...**** an I just bought a 36k, 3 year bumper to bumper
where have you been?Yes, it would most definatly void a warrenty. Why would a company want to pay for your modification to their " Perfect " idea of what the car should have and not have.
X2Just save your old alt. and put it back on if you take it to the garage. What I do with the Subaru.![]()
