It is one of the more difficult jobs due to the fact that is is located on the passenger side by the rear wheel. I tried to take it out and realized that it was too cramped and tight to do it myself. I took it to my mechanic, Nguyen's in Santa Clara, CA, and it took his shop two hours to do it. My advice, take it to a shop unless you want to completely frustrate yourself doing it. bo
The Mk1 NA alternator is easy, two bolts and an electrical connection. Alternator is mounted like earlier automobiles, with a long bolt on bottom and an adjusting bolt on top. The Mk1 SC is much more difficult, as it was moved to the front of the engine to make room for the supercharger, and is above the AC compressor. To change the SC alternator requires either removal of the AC compressor, or (and not easy) it can be removed and reinstalled through the engine's air vent. Either way is difficult. As far as the sc model I found it far easier to remove the 3 bolts and unplug the side fan. Lay the fan all the way to the bottom of the engine compartment below and out of the way of the alternator. (You do not need to pull it completely out of the car.) Remove the outside passenger side cowl with 2 screws. Loosen the tensioner on the alternator belt then remove the belt from the alternator pulley. (First loosen the pulley nut and then back off the long tensioning bolt from the bottom.) Unplug the green plug from the alternator. Unbolt the bolt from the top and the long bolt from the bottom of the alternator. A short pry bar helps lifting the bottom of the alternator from its bracket. Then undo the 10mm nut on the charge wire. Now reach through the quarter panel and ease the alternator back and out through the vent hole in the quarter panel. It took me 30 minutes. I promise you there is no need to remove exhaust, compressor, distrubutor, or engine/trans. Hope this helps.

To check the alternator on your 1988 Toyota MR2, first ensure the battery is fully charged and the connections are clean and tight. Start the engine and use a multimeter to measure the voltage at the battery terminals; it should read between 13.8 to 14.4 volts if the alternator is functioning properly.

Additionally, listen for any unusual noises from the alternator and check for signs of wear or damage to the belts and connections.
