The battery light came on while I was going to work and the car began to loose power to everything as I pulled into the parking lot at work. I plan to buy a new alternator install on my 02 toyota camry 2.4L. Looking for a car alternator replacement,there is a 80 amp and a 100 amp available. Which one should I choose ? The higher amperage alternator,the better ? Is there any place where I have to be careful when buy an alternator ? Please advice.
Ordinarily I would say if you can determine the amp rating of the one you are replacing then I'd replace it with the same amp rating, that amp rating has worked with your car for 17 years so ought to be good enough. You also know it should fit exactly, an uprated one may take more space than would fit in a cramped engine compartment.
However, if there's enough space under the hood a 100 amp unit costs almost exactly the same, so if it were me I'd put the 100 in provided it's not a squeeze.
The 100A would be an upgrade over OEM. Unless you're super into automotive audio and have turned your car into a boom car with a lot of amplifiers, 80A should be plenty.
I heard high amp alternator will rob more power from the motor. I don't want to risk,so just bought a 80amp alternator replacement online from Hex Auto Parts last week. It has been working fine for some days and provides enough power to run my 05 toyota rav4 and accessories.
