2002 Dodge Caravan- alternator rattle

2002 Dodge Caravan- alternator I have a 2002 Dodge Caravan with 3.3 engine with 75,000 kms. I'm getting a constant rattle sound that I have traced to the alternator, and can heard the loudest with the engine idling. Is this a common problem with this vehicle? Any helpful ideas on the root cause, and ways to correct the problem rattle would be greatly appreciated. Thanks! Same thing: Rattle, growl and tapping coming from the accessory side of the engine that increases in speed as the engine RPM's go up. My improvised stethoscope pointed right at the alternator. The rebuilt one I got from AZ made the same sound, and actually failed on the road after 2 hours of operation. The old one, still in the back seat, got me home. The rebuilt Mopar I got from the dealership also made the same aweful noises. So, I went to my local Alternator Rebuild specialists in town and they gave me the real lowdown: My alternator bearings are Great; The brushes should last 250k miles; It's a dual stator Alt (one of the best); but the clutch pulley on the front was bad. He replaced it. Now... if it continues to sound bad, what's the most likely culprit?

Check for belt alignment, the 2.2 had a problem with the water pump pulley being put on back wards.

Hope this helps.

Thanks, Dave!
I actually found the problem within a week of my posting. The 1-year-old serpentine belt I got from AZ when I replaced the water pump had a 1" chunk missing on the grooved side causing the loudest "thunk" when it went around the smallest pulley.. the alternator! There was never anything wrong with my original alternator. (And the only one that went bad in the process was the rebuilt one I got from AZ!!) I have to admit, AZ has been a friend when it comes to loaning me special tools and helping me troubleshoot; and the guys are great.... but many of their parts can't be trusted. I recommend getting parts from the dealer, and oil-changes and windshield wipers from AZ. But I almost had to laugh.... All this hassle when I KNOW by now to look for the simplest solution.

2002 dodge grand caravan won't start

Hello, Just by my experience with my 91 dodge grand caravan, I would start checking 3 things. First, did you replace spark plug wires to the correct location(Plugs 1, 3 and 5 on the back, Plugs 2, 4 and 6 on the front,That's all starting from the Passenger's side.) 2nd, do your dash lights and electronics turn on when it turns over? If not, try jumping it and 3rd if engine finally runs after that and then shuts off, then your alternator will be next to check however if engine dosen't start running from trying to jump it then the problem is more than likely your alternator. Though make sure you have plugged in all plugins that you might of unplugged like the one that plugs into your DIS coil pack and all vacuum hoses are connecting. Hope this helps and good luck!

2002 Caravan,3.3 V6,FWD,had a loose rad cap and lost fluids till no heat in heater.Replaced cap,filled overflow reservoir,ran for a few kms,refilled tank.Still no heat unless motor revs,all levels are...

You still have a lot of air in the cooling system and you have to speed up the water pump to get any coolant to flow through the heater. Let the engine cool off, then open the radiator cap and top off the radiator. Pour the coolant in at a rate slow enough to let the air bubble up without splashing the coolant back out. Once you get the coolant level up to the top overflow hose, the remaining air will be pushed out by expansion through the overflow tank once the engine gets hot, and will be replaced by coolant from the tank on cool-down.

How to change alternator for dodge caravan 1996

if you have a 3.3 engine then that job looks almost impossible ... same for the rear spark plugs .. i gave up and took it to a dealer ... i asked the mechanic how in the world he managed without taking the engine apart .. he said "i took the engine apart (with a big smirk)" ... he wouldnt tell me what but it looks like you have to take off the intake manafold ... maybe even the rear valve cover (to get at spark plugs) ... thats a wonderful engine .. nice machine, lasts forever .. but the human engineering is awful .. i noticed that the new caravans have corrected that .. they have lots of room to get at things .. also the smaller engines give you more room .. it cost me over $300 just to have the back 3 spark plugs changed .. another time an alternator was loose in the middle of nowhere ... a mechanic welded and bent several wrenches together to make a goldburg type tool to get at that hidden nut at the bottom of the alternator .. dodge could have made that much easier (possible) if they had made those "captive or welded" nuts .. as it is, the nuts are loose and impossible to control without "taking the engine apart" if you do manage to get them loose (without dissembling the engine), you cant remove them completely since you cant get anything to hold the hidden nut .. and you wont even be able to retighten without that bent and welded special tool .. i noticed that the front bearing on the alternator is what fails more often than other things .. so after the first 75,000 miles .. i put a drop of syn oil on that at every oil change .. that seems to extend the life considerably .. be careful to clean any oil that gets on the belt .. also check the spring loaded belt tensioner ... make sure it still moves on its pivot .. they often freeze at the pivot and that can cause damage to the alternator bearing ...
