I need to replace the alternator and thermostat in my 92 Cherokee Laredo. Can anyone point me to any threads or links that will give me instructions and helpful tips on how to do these replacements?
I will probably be getting the alternator from Advanced Auto or AutoZone. Are there any particular brands or models that are reccomended? Which ones should I avoid?
I will probably also change my upper and lower radiator hoses as well. When I purchased the upper and lower hose I only got to larger diameter hoses. Now I see there is a smaller diameter hose attached next to the upper radiator hose on the thermostat housing. What is this hose called and what size is it?
Replacing you thermostat is very easy, its located at the top of the block at the front of the motor. Just about any brand from the major brand auto parts stores will do. I replaced my 210* thermostat for a 195* one and haven't had any problems. I believe the thermostat attaches with two bolts, just be sure to clean the gasket mating surface really well before re attaching it.
As for the alternator, its located on the passenger side of the block at the bottom of the engine bay. Its easily reach from below the jeep. (You may have to remove you drip shield if you still have the rubber liner from the factory.) The alternator itself is held on by three or four bolts. But to get the alternator out you will most likely have to remove the thin metal bracket that attaches to the block. To get the alternator to come all the way out you may have to loosen the belt to get the alternator out. Then just unplug it and remove the grounding wire. Should be good to go. Replacing your alternator and thermostat will most likely take a few hours, but you will learn alot doing it.
A word of advice on the alternator, buy an alternator that comes with a lifetime warranty. Since our alternators are located so low in the engine bay, they take alot of abuse from water, mud, snow, rocks, etc. So get one that you can take back and replace easily.

Buy good quality parts from O'Reilly or NAPA. Advance and IdiotZone sell cheap parts. A lifetime warranty on a cheap part isn't much good if you spend the rest of your lifetime running to the parts store to exchange your now dead cheap part for another one.
