1995 Infiniti G20 alternater and power steering belt replac

If it is the 4cyl. You will need to remove cover under car in front and a small side one behind wheel. Easier to just jack up passenger side and remove tire. Use safty block under car. Air and alternator belt is losened from above. You losen a side bolt than holds the adjuster tight then back out the adjuster bolt nost of the way. Remove belt from below. Pull hard on belt from below and it should move the alternator.
Power steering, this sucks. Losen side bolt from above it is on the left side of pump. You will need to losen adjuster bolt from below and up thru steering. Remove belt form below. Install in reverse and tighten.
