New Brakes by winter2
Jan 12, 2009 (11:20 am)
Reply
Last week I had new brakes installed on my CRD. I had to throw out the original rotors and pads with 43.8K on them. The rear pads were totally warn and the rotors(by Bosch) had some hot spots on them. The front rotors (made in China) were warped but the pads were in good condition with about one-half of the friction material remaining. Both the dealer and two mechanics told me that MOPAR OEM brakes were junk.
 
I did upgrade my brakes. I am using rotors from ultimate braking. They are cross drilled and slotted (both front and back) with high performance semi-metallic pads. Got about 150 miles on the new brakes and they are sweet. Stopping distances are much shorter and the brake pedal feel is very good. Had the system flushed and had synthetic DOT 4 brake fluid put in.

Weird issue - No power by drudgery
Jan 12, 2009 (3:09 pm)

I have a 2005 CRD with 75k miles, (LOVE the truck despite some of its issues) and had all the normal recall stuff done but am having an odd problem I think may be related to the EGR or fule/air sensor of some kind.
 
Description of problem:
Will be running just fine for miles can occur (warm or cold) and then occasionally when stopped at a light/stop sign for several seconds we pull away and there is absolutely no power and the farther you push the gas the less power (will not go above 30-40 mph. The weird thing is to make it go back to normal all you have to do is let it idle for 5-10 seconds and then go again and everything is fine.
 
I am planning on taking it to the dealership this week but I wanted to get the real scoop here because they only work on about 2 or 3 of them I think. Any help to determine what might be causing or what is not casuing it are appreciated. Thanks -- Andy C

Serpentine Belt and Tensioner by Eastcoastz

I have an 05 Liberty Diesel.
 
Had my Jeep in to the mechanic today said I needed a tensioner and Serpentine belt.
 
Belt $170
Tensioner $ 310
 
Think this is extremely steep since it is a simple piece of ruber and a tensioner and without labour already up to 480. Has anyone required a replacement of these parts and if so have you been able to get a better deal? Thanks for all your help

It does sound like the EGR might be hanging up, or the "throttle valve" on the intake.
Have you tried "blowing its nose"?
This can clear out the system.

O'Reilly auto parts online
Belt $24-$60
Tensioner not listed.
 
I have 135,000 mi on original belt and it still looks good.

My serpentine belt was changed according to the EU manual ( ) at 60,000 miles.
 
It was in a fine condition but the dealer changed it arguing that they had to do it according to Jeep prescriptions. They did not route the new belt in the proper way and I repositioned it later. This is what I observed:
 
The tensionner's spring should last the life of the engine, the bearing inside the pulley is another story. Mine is still fine and I have about 90,000 miles on the truck.
 
Changing the serpentine belt is very simple as long as you have sufficient light, dirty overalls and that you can reach the bottom pulley to follow the pattern shown on the sticker.
 
You need a 15mm box wrench with a lever 20 inches long to retract the tensionner without effort; once kept retracted with one hand, you slide the belt on or off the alternator pulley with the other hand. You use the nut from the shaft of the pulley to swing the pulley out of the way. This also tightens the nut if needed.
 
It should not take you more than 10 minutes unless you are curious. Don't forget to remove the oil and dirt of the air hose before you start

Caribou1, would the chirp I hear from time to time on acceleration, have anything to do with the belt tensionner spring. This noise occurs at lower speed under acceleration and around 2000 rpm.

When you say they changed the belt at 60,000, was this a recall if it was mine was never done do you have any further information on this recall?

I also had the "chirp" sound when:
- my alternator (built-in voltage rectifier) had gone bad
- my belt was not in the proper position
 
Assuming your serpentine belt is installed properly, I would do the "alternator field check" first:
- stop the engine and disconnect the little connector behind the alternator. It's shaped like a "D" and needs to be pinched to be removed. There are two side clips molded into the connector. Turn the engine on again and listen.
 
My belt was in a wrong position after it was replaced. My alternator died after the belt was replaced. Is this pure coincidence? I don't know.

No, simply customer abuse.
In the EU we must pay more, more frequently, and accept to get no accurate answers to technical issues. Modern vehicles are loaded with electronics and those who decide to buy Asian cars never change. This is a severe threat to our industries.
