There is a pulley directly underneath your alternator that has a nut on the back of it. You'll need a wrench to put on it and push down to get slack on the belt. After removing the belt there are three bolts (two in the front and one on the back) that need to be removed. Then disconnect the wire harness and you may need something to pry the alternator out of the Bracket and that's it.

disconnect the battery first

Generally you would need to have a replacement alternator which is only around $60 and it is refurbished but a 1999 Chevy Tahoe alternator should work just as well

the alternator will be located close to the top of the motor, you will need to loosen the tensioner pulley and remove the serpentine belt, disconnect the elictrical connections at the alternator and remove the alternator mounting bolts. then just lift the alternator out... as far as tools you will need a basic set of sockets and a screwdriver.

NO. Not even close. Chevy redesigned ALL the TRANSMISSIONS and ENGINES in late 1999. Anything above 1999 WILL NOT FIT anything under 1999.

Remove the belt from your 1999 Chevy Malibu alternator. Remove the wiring harness from the back of the alternator. Remove the alternator retaining bolts. Reverse the process to install the new alternator.

I hope this question is about the engine coolant thermostat. If it is and you have to ask this, you shouldn't be allowed near a vehicle with a tool.
