Question about Chrysler 300M

1 Answer

I have a 2000 chrysler 300m with a v6 and it started out for about 6 mo0nths power steering would work normal then, really overly good, then really poor, then no power steering, then it would work again. It would go through these cycles and not in any order either. But more often then not now it is super tight hard to turn. What could it be? Can I test to see if it is pump or steering gear? I hate to buy stuff without testing.

    Well This is first time I used this site and was in a hurry, but I did just replace the pump a few days ago and it is doing same thing so I was kinda second guessing myself thinking maybe I did something wrong but I installed pump exactly like chilton book said and I bleed it by turning wheels right and left without hitting stops.  Steering was ok not great for 2 days and now hard as can be again.  My book just tells me how to remove steering gear but nothing about testing it.  I am pretty good at fixing things I take apart but still got a lot of learning on cars.  Heavy machinery and computers are my gig. ha  lol   This is my only car and I am at a loss.  I am going to test pump like you said but do you think it is still the pump even thou I just replaced it? I am sorry for not mentioning that, I know how hard it is to figure things out when someone doesnt tell you everything thats been done.  again sorry

I could see that the power steering (p/s) is working intermittently. Most of the time, it's the p/s pump has the problem. But it's better to check the steering gear and the fluid level.

Yes you could test the pump, here's how:

1. Check the fluid levels of your vehicle first. Add power steering fluid if necessary before you proceed any further.

2. Connect the power steering pump and hose to the pressure gauge and shutoff valve. Fit the hose to the power steering pump correctly. Make sure the shutoff valve is open before test the power steering pump.

3. Idle the engine while turning the steering wheelI have a 2000 chrysler - mag-glass_10x10.gif all the way to the right and all the way to the left to release any air from the power steering pump.

4. Close the shutoff valve to check system pressure for about 5 seconds. If the shutoff valve is closed longer than 5 seconds, your power steering pump can overheat and this can cause damage to the pump itself.

5. Compare the pressure reading against the manufacturer's specifications. If the pressure is within limits, your power steering pump is working correctly and you're ready to roll.

6. Troubleshoot if the pressure reading is not the same as the manufacturers specifications. Consult the manual for your vehicle or for your power steering pump (if you just installed a new one) to determine the source of any further problems.

Hope this helps and have a great day!

    It's okay, I understand. Yes, it would be better to perform a test to make sure that the pump is still working correctly. It's okay to test it even though it's new.

    Sorry, for the steering gear, you actually need to use a testing device or analyzer to test the steering gear. But kindly check the link below and it might help:

    Have a good one!

I don't know how to turn the cruise control on in my 2002 Chrysler 2000 300M

All you gotta do is hit the on button on your steering wheel then accelerate to any speed above 35 mph. Once there you press set and the cruise control takes over.

2000 Chrysler 300M V6 with 150k miles started giving a clacking noise from the engine area after getting an oil change from Jiffy Lube. I was less than 2 miles from their shop when it started clackin

Sounds like your valve lifters. It's possible that they drained the oil and never refilled it. This does happen when they go on break or lunch half way through a job. They think they added the oil, but did not. Out you go, Mr. Clack-Clack.

Cd System in 2000 Chrysler 300M

Had same problem wit my 4 disk. A CD was jammed. Remove and open the unit up and remove the CD. The mechinizem might be jammed also. Try this before replacing. Seems like a common issue with these units. The newer 300Ms came with 6 disk changers.. not sure if these will work with the existing radio.

Good luck!
