"clickety-clack"/"whine"

[studio460]

FYI:

Marauder "clickety-clack":

I just cracked 2,500 miles on a trip to Las Vegas. Upon my return to Los Angeles yesterday, I noticed a VERY subtle "clickety-clack" noise also (see "My axles needed to be replaced" thread below).

Marauder "whine":

Upon receipt, my Marauder whined 100% of the time (with no correlation to RPMs)--apparently from the cooling fan. The whine came from the engine compartment, not the rear end. When I took it in to replace the power steering pump (which failed the first day) the whine magically disappeared. They ordered me a new fan assembly anyway (which I haven't yet had installed) and the service writer noted that the "fan never turns off." Should the Marauder's fan be turning on and off normally? My temp gauge is consistently pegged at a nominal temp (after warm-up). Is everyone's fan "on" all the time?

Grand Marquis rental had "drivetrain" whine:

I recently drove a rented Grand Marquis for four days and noticed a definite "whine" which seemingly did correlate to RPMs. Although I couldn't swear by it, it seemed to come from the transmission (or at least somewhere in the drivetrain). If I recall correctly, the whine was audible 100% of the time, although it appeared to be most noticable during hard acceleration (and, I think, the whine's pitch increased with acceleration as well). Additionally, I noticed that this rental also had the "can't-engage-into-reverse-very-easily" problem reported elsewhere. By the way, after A-B'ing the two cars, the Marauder really kicks the Grand Marquis' butt (can we say "butt" here?)! The difference is amazing (and my MM is still stock!).

Your cooling fans should cycle off and on.

"clickety-clack" Should be the injectors firing. Check by using a dowel or broom stick(like a stephoscope) held up to the injector or fuel rail. Then try putting it up to other parts of the engine. The sound should be more pronounced at the source.

Oppppps meant to post on the clickety clack........What looking said. There have been several reports of that on here and mine does the same. I believe it to be injectors as well.

As far as the whine........it usually comes from the RF seat and repeats often........slow down.....slow down.....slow down.....
:lol:

Sorry couldnt resist.

Wolfe, sounds like you need to have an RF modulator installed.

Sssshhhhhh........don't say RF so much.....or he might show up.
:lol:

Shooter,

Don't know how pronounced the whine is, but I sometimes hear it from the tranny area also. There was a thread posted way back with a post from Dennis Reinhart stating that it was the whine of a healthy tranny pump. I can hear it under moderate and hard acceleration, but not all the time. Other than that, I don't hear anything odd from that area.

As for the other noise.....What everyone else has said. My '99 Cobra had noisy injectors as does my wife's Windstar V6.

I don't think my fan has ever come on.........I don't recall hearing it.........
