#104 of 142 New Engine noise by cincyblazer Nov 10, 2007 (11:34 am)
Just today, my 2002 2-Dr blazer began making an engine knock at startup. Once the Engine temp reaches 210, the noise stops. I have also noticed that the oil pressure guage fluctuates while driving. Does anyone have any ideas. Replies to this message: jlflemmons (Nov 15, 2007 3:09 pm)

#108 of 142 95 Blazer electrical problem by jimbob11 Dec 30, 2007 (7:12 pm)
Have V-6 Vortec- When I turn on w/s wipers, they don't start right away and the radio turns off. There is a audible buzzing coming from the dash or the cowl area(drivers side).This lasts for about 10-15 seconds. After I turn the wipers on high, they will eventually turn on and the radio will come on also and the buzzing stops. Ever since I've had the vehicle, when I turned the wipers on intermittent, the radio would stop playing when the wipers came on, when they paused, the radio would play. Now the the buzzing problem. During all this, the battery never seems to go into discharge. Any suggestions on what to check? I have had no other known electrical issues.

Replying to: 53jinx (Apr 10, 2007 5:25 am) I have been having belt noise since last June. I bought a belt from Pep Boys and they put it on because I was having problems getting it on. I think they charged me like $20 or $30 JUST to put it on and it took the guy like 3 minutes. Anyway, the noise barely went away. It had/has gotten worse the past few months. I would spray a lubricant on it every so often, but, the noise would come back in seconds. I tried belt dressing, against my better judgement, yeah it didn't work at all. DON'T USE BELT DRESSING ON SQUEAKY BELTS. Today I saw where you said you used silicone grease. I ran up to ace, bought some and put it on, it worked GREAT. I'm affraid tomorrow it will be back, but, we'll see. My belt is under warranty at Pep Boys, but, they will only exchange it, not refund my money. Why in the world would I want the same belt?!?! I was going to try a gatorback belt, but, I'm farely poor ha. So, I just hope the silicone grease works. Thanks!! Replies to this message: jlflemmons (Mar 10, 2008 8:02 pm)
#111 of 142 high idle on 97 blazer by horsey Mar 09, 2008 (6:19 pm)
I have a 97 Chevy blazer w/ V-6 Vortex engine. About a month ago it starting idling higher than normal until it warms up. When you are on icy roads and come to a stop sign, if the idle hasn't come down yet, it's like trying to stop with one foot on the brake and one on the gas, which isn't good!! The high idle eventually comes back down after awhile. One buddy though it might be the throttle positioning sensor and another buddy thought it might be the idle air control sensor. The check engine light doesn't come on though, so I was told I probably can't get a code. Anybody thoughts would be greatly appreciated.

Replying to: tommygemini (Mar 09, 2008 2:43 pm) I finally had to give up on the Gates belt and go with Goodyear. A trusted mechanic told me they have had problems with Gates serpentine belts chirping and squeaking. He said it is because the Gates has continuous grooves with no breaks and can trap oil and dirt.   Since I changed to the Goodyear belt I have had no noises in over 3 months. Seems to be fixed.
