I have a weird sound too

[spdrcrj]

It happens when the truck temp is cold, last for only about 5 secs then is gone and doesnt happen when the truck is warm. Almost sounds like a sportbike driving by (I actually looked behind me the first couple times this happened to see who was riding by). Exhaust leak that's sealing up?

Nope :dontknow:

interesting? exhaust would be more of a clicking noise. need more details. what speed, gear, ambient temp, turning or coming to a stop, accelerating, cruising.

Sound only happens when the truck is cold (first start of the day). Not turning, stopping, accelerating, cruising or anything. I start the truck, sound starts, gets slightly louder, then stops, lasting only about 5 secs then doesnt happen again until the truck is cold (as if starting it for the first time of the day).

I use to have a cold startup sound, a whine, really noticable in the garage. Started out low and would get louder, and yes, about 5 seconds or so. When I put on my exhaust either

1. It went away
2. The exhaust is to loud to let me hear the whine :rock:

Fuel pump priming??:dontknow: Maybe you have a small leak in the fuel pump check valve or whatever keeps the fuel from draining back into the tank and the fuel pump is re-pressurizing the system. I don't know, I'm just guessing.

Have you checked your harmonic balancer bolt?? They've been known to be loose on the '04's and early '05's.

when mine sits for more than a day and during initial start-up for about 4 to 5 seconds- to me sounds like the oil priming up in this BEAST of a motor we all enjoy.

any thoughts

Back in o4 when these trucks were new there was post about startup noise......some described it kinda like a whine, sorta like a f15 plane sound. Turned out to be the power steering pump or something. I had it too.

I'll pay more attention and try to pinpoint it's location. I'll pay special attention to the powersteering pump. I'll post any findings.

 

[silverqc]

mine was doing that found when it was happening the power steering would be very hard (turn the wheel) had the system flushed and fluid change havent had the problem any more ,might be your problem maybe
