Fuel Dampers & Service Manual

Hi, all. I'm a new member and have a couple questions I hope you can help with. I have a 2003 Murano SL with 87,000 miles. I just learned that my fuel dampers have shot craps. The dealership quoted me $500 to replace them . . . WOW! That's after sticking it to me for $275 to replace the transmission fluid. Anyway . . .

First Question - How difficult is it to replace the dampers on your own? Keep in mind, I have very little mechanical experience.

Second Question - If the answer to the above question is "easy," can anyone provide a step-by-step guide on how to replace the dampers? Pictures or video would be great!

Final Question - Can anyone tell me where to get a good repair manual for the 2003 Murano? I plan on replacing the coolant and doing my own brake work soon so I'd like a good guide.

Thanks guys and this is a great forum!

Prob8-

Welcome to the forum.

The MO has two fuel dampers. It is rare for both to fail. If you can isolate the bad damper it can save you some money.

The fuel dampers are located under the engine cover. With the engine idling, grab each damper and feel for the vibration. The damper that has the vibration that coincides with the noise is the bad one.

For $20 you can buy a 24-hour subscription from Nissan that enables you to download the service manual. You will need a fast Internet connection because the manual is made up of approximately 40 pdf files.

Here's the link:Nissan Publications - Online Subscriptions

Good luck.

That's really not a bad price, especially if it was for a flush, considering how much fluid the trans holds and the cost per quart. More likely, it was just a drain and refill, however.

I'm wondering why it was done at all at only 87K miles. Perhaps you bought this car used and a fluid analysis done by your dealer showed significant deterioration?

Thanks for all the help. After review of the manual, it looks like I'm in over my head. I guess it's off to the dealer.

njjoe - Thanks for the tip. I'll make sure both dampers are bad before allowing the dealer to proceed with replacement.

nitely - The link you gave was perfect! I was able to immediately view the manual. Thanks.

nafddur - I bought the car new in 2003. The dealer recommended the fluid change based on his "experience" with Murano transmissions. I thought changing was a bit early but since I plan to keep the car several more years, I went along with it. I had to laugh when you mentioned a fluid analysis. You give the dealer way too much credit. He made his recommendation as soon as I pulled in the service bay and he saw the odometer.

Thanks again guys!

Though this is far from the worst thing I've heard of dealers doing (and changing the CVT fluid at 78K miles certainly can't cause any harm, other than wasting a few of your hard earned bucks), I'm SURE glad I have an honest dealer! They do exist.

update . . . cost to replace both fuel dampers was $500. That sucked but at least the annoying diesel engine sound is gone.

I have a 2003 Murano with the same damper problems, what problem will it cause if they are not replaced right away? The dealer said both of mine are bad!!!
Thanks

Although I can't directly answer your question, I can tell you that it was about a month between the time the noise was first noticed on mine to the time the repair work was done. It does not appear that waiting that long did any harm. You might want to give a call to the dealer to check with them. Good luck!

It connects to the fuel line that runs from the in-tank fuel pump.
