#422 of 427 1998 GMC Sonoma Horrible Noise From Under Hood
Mar 24, 2013 (8:46 am)
I have a 1998 GMC Sonoma V-6 that is making a terrible noise from under the hood.
The noise is so loud that it makes it difficult to isolate. It sounds as though the noise if coming from either the a/c compressor pulley/bearing, the power steering pulley/bearing, or the water pump/fan clutch (in that order).
I removed the belt and spun all of the pulleys.
The a/c compressor pulley has a slight wobble to it and creates a noise similar to a bearing going bad in a skateboard wheel however there is no grinding or sticking in the motion of the pulley itself (although I suspect it is the culprit). I have not had a working a/c unit for almost 5 years so I would not mind buying a by-pass pulley to replace the compressor altogether.
When grasping the power steering pulley it has play back and forth but not up and down. When I spin the pulley it seems as though it is smooth and makes no noise that I can detect.
The water pump and fan clutch (when spun) is smooth and hardly makes any noise at all but I did notice a little weeping (fluid) on the water pump itself (smaller than dime-size). My truck stays at a nice temp so overheating is not an issue (yet?).
I have bought multiple "quiet" belts in the past 2 years but it does not seem to help that much. I have replaced the idler pulley, tensioner pulley, alternator, and serpentine belt all in the past 2 years.
I took it to a local shop 3 months ago and they could not isolate the problem either. They said they put brake lubricant on the smooth part of the belt and the noise went away completely - for one month. They said it was the labeling on the belt and I took their word for it.
They recommended putting more brake lubricant on it every month (a big "dab" they said) to alleviate the noise. So I followed their suggestion but it no longer has the same effect.
Yesterday I cleaned the belt with mild soap and water and cleaned all the pulleys with a degreaser and made sure everything was dry. I placed the belt back on and the same noises were coming from the engine bay.
Without buying EVERYTHING and walking into a dealership with a blank check, I was curious if someone had a similar issue or suggestions to help me isolate it further.
If I left out any information, please let me know and I will do my best to help.
#423 of 427 how to fix the ecmb blown fuses issue when all else fails
Apr 21, 2013 (3:04 am)
ECMB fuse blowing on my 93 Chevy S-10 Tahoe 4wd.
I have been fighting this for 3 weeks now and just tonight I think I have found a way to solve the problem without any costly or major repairs. It's only cost me bout 20 bucks and was an easy and fast fix once I figured out how to do it. That is 3 weeks later but it works fine for me and I didn't have to change the entire wiring harness.
First I disconnected the battery to prevent damage to the ecm. I went to the auto parts store and bought 40 feet of good quality 14 gauge automotive wiring, an inline blade single fuse block some wire connectors electrical tape and some tools to get trim down to access the ecm. If you can get to the wires without removing the brain even better. I was able to luckily.
I started at the fuel pump relay. I cut the orange wire a few inches of the relay. I did the same with the grey wire. I taped the ends and they won't be used anymore. I spliced my own wire into the orange wire and I ran mine directly to the battery and put my fuse block in where I spliced another wire into it to run to the ecm. So a single wire comes from battery into the fuse block and on the other end of the fuse there are now 2 wires one to relay and one is going to go to the orange wire coming out of the plug on the ecm a 3-way splice.
Locate orange wire on ecm plug cut it down far enough to splice into splice your hot wire that is coming from your 3-way splice from battery. You now have bypassed the orange completely and you have a new always hot wire going to oaring on relay and one to orange coming off ecm plug.
The next thing you do is take the gray wire that's been cut and coming off the relay plug and splice a new wire into it run it back to the fuel pump plug. At the tank cut the gray wire on the truck side of the harness, not the pump side of the harness plug, splice in your new wire coming off the gray at relay. Only cut the gray wire, the other is the fuel gauge wire and doesn't need to be cut.
Plug your fuel pump plug back in connect your battery make sure your relay is bolted back in place on firewall and you're good to go. My truck still blew the ecmb fuse on the fuse panel inside the truck, but it didn't affect the pump because I bypassed it all so I just left the fuse out of the ecmb slot on fuse panel in truck and everything works great again.

I have a 2003 sonoma p/u. I have changed the thermstate and I still have no heat. I also see that the temp. of the engin is running cooler then normal, which is why I changed it. This did not work and I am not sure where to go next.

The engine overheated. I saw the temp gauge go up and down. I replaced the tstat, wpump, and radiator. Now I have a leak at the rear of the engine, and a hissing sound. Hope its not a cracked head!! Anyone heard of this? #chain reaction
