Sierra :: 1989 GMC - Brake Pressure Fading / Goes Completely To The Floor
I have an '89 GMC Sierra which has the standard rear wheel anti-lock brakes offered that year and a vacuum booster. It has about 180,000 mi. on it. I have a problem with the brake pedal fading to where it goes completely to the floor. This happens whether the engine is running or not. The brake warning light is not on (but is operable), there is no air in the lines, and their are no external leaks. The resevoir has stayed at full level. I rebuilt the master cylinder and the bore looked great as did the seals, but I installed the rebuild kit anyway.
There has been no change in performance. Can this be a problem with the isolation/dump valve assembly leaking internally. I would think that would cause the warning light to come on. The i/d valve is a costly part to replace and I hate to experiment on such a solution without some confidence in the source of the problem. The GM Service Manual troublshooting indicates air or internal master cylinder leakage is the culprit, and indicates the light would come on for any i/d valve problems.
Gmc - Sierra :: 1999 V8 Buzzing At Very Low Throttle
I have a 1999 GMC Sierra 2500 with the 6.0 liter V8. I have right at 130,000 miles and I have a very annoying noise at very low idle. It's a buzzing sound whenever I put very light pressure on the gas peddle. When I depress it further the noise stops, but I don't always want to burn out of parking spaces.

I have a 2004 gmc sierra and it is having heater issues. For a while now when starting it up cold it would not blow any warm air until the vehicle is moving. The other day while driving it would go back and forth between hot and cold.

I have a 89 ford mustang with 4 cylinder. After being stored for the winter I noticed anti-freeze leaking from drain tube below heater core (small amount). I am not looking forward to replacing the heater core in this car! Any reason this happened after the car sitting in storage all winter??? or just a coincidence??

My grandson keep his 93 GMC K1500 w/5.7L auto running till he gets out of college. The problem is the engine stalls (sometimes) when put into gear (D or R) and more often when the lights and heater blower are turned on. There were two codes in the pcm (42 & 43) both referring to ignition problems. We did a tune up and erased the codes. After driving the truck for a week the pcm has no codes but the engine still stalls. We cleaned the IAC pintel and seat thinking there might be an air control problem, no luck. The repair manual mentioned ignition advance as a problem particularly the ESC. The manual says this part is on the side of the throttle body but we can not find it.

Found a tee on the heater hose leaks when it warms up. Appears the PO had noticed it but put a hose over it and now is leaking around behind the valve cover. This is a hard plastic line around 5/16. No online parts show it as being available. Is there a fix for this ?
I would bet several others have had this problem as it lays right on top of the flange of the valve cover where I think it would rub a hole pretty quick.

Sierra :: 2000 5.3 Sierra Suddenly Overheated In Cold Weather Then Fine
A friend of mine has had this 2000 Sierra since new. It has just over 100K and never had any cooling issues before. Last week when it was about 10 below zero she drove it home and it overheated and pumped a couple quarts of antifreeze overboard.
She refilled it the next day and it was fine but got it looked at by a local independent mechanic. I had told her that it was likely a sticky thermostat and it ought to be changed out anyways due to its age. The mechanic thought I was wrong and that she had driven it off to quickly in the super cold weather.
Sierra :: 2006 GMC Z71 - Noise Starts At About 50-55 And Keeps Getting Louder With Speed
I have a 2006 GMC Sierra z71 has 159,000 miles on it. I've already changed the front hub bearings and the tires are brand new. Brakes are in good shape as well. I also had someone check the front differential bearings too. Said the front diff was good. The noise starts at about 50-55 and keeps getting louder with speed. The noise is similar to a hub bearing noise. When you let off the throttle the noise is more pronounced then when on the throttle. I'm thinking it's te cv axles. The cv boots don't have any tears in them and I have no clicking noise. But I've also heard that cv axles can make this noise. Also the noise seems to change when I hit bumps. that's also why I'm thinking cv axles. Because cv axles are the only thing that move with the suspension and also rotate.

View 1 RepliesGMC - Sierra :: Rubbing Noise That Seems To Come From Front Passenger Wheel
Concerning my recently purchased '99 GMC Sierra 1500 2wd 4.8L...
There is a seemingly undiagnosable, not that noticeable, rubbing noise that seems to come from the front passenger wheel - one rub for every revolution of the wheel. It is fairly subtle and can be felt (subtle) in the steering wheel between 30mph and 45mph. I don't think a lot of people would notice it and anyone that did would probably just turn up the radio at this point. After all, this truck has a very solid drive train and runs amazingly smooth for its age and mileage (172K)
Here are the repairs I have made that you might be about to suggest:- New front bearing/ hub assemblies on both sides within the last year. No play in any of the wheels.- New tires from Firestone within last month.- New tie rod ends and alignment. - New rotors, pads, and flex lines on front. Refurbished caliper on passenger side front.- New pads, calipers, and flex lines on rear. (one of the calipers had seized and I thought I had finally found the problem... not.) (one of the flex lines was the wrong part and was rubbing up against the rim... I thought that was the problem... not.)
Here are the things you are about to suggest I check:- Transmission, rear axle bearings, etc checked out by my trusted transmission shop. - Wheel well shields are firmly attached.
Things I haven't yet fixed : tail pipe bracket, evap emission solenoid assembly, blower fan resistor thingy, crappy door latch.

View 3 RepliesSierra :: 1991 GMC 1500 Won't Start - Not Making A Clicking Noise
I'm working on getting my GMC seirra 1500 5.0 L running. Last fall When I was making a trip to another town, it broke down. When it broke down it smelt like plastic was burning, I was unable to figure out what the smell was.
First I though it was a bad battery connection, or that the starter had went.
I changed the Battery, made sure the cables were good. changed the starter and it still doesn't work.
I know the battery is working for sure because There is power to the lights so I can turn on the brights. There is no power to anywhere else on the dash though other then the icon that shows the brights are on.
When I try to turn the engine over, nothing happens at all. Doesn't even make a clicking noise.
GMC - Sierra :: 1999 - Rear Drive Terrain / Differential Noise On Acceleration
I have a 1999 GMC Sierra. The rear differential cover was leaking on me for past couple of months, but I was putting it off. FInally this weekend my truck starting making an airplane sound that seemed to be coming from the rear. The sound happened on acceleration only, and increased in amplitude and frequency as the speed increased and as I pressed the gas more. If I let go of the gas, or let it cruise, then the sound would sputter once or twice, and go away. It would resume if I pressed on the gas again.
Since the rear differential cover was leaking, I thought I burned out the gears. When I changed the cover, the gears appeared to be fine. The lubricant was super low, and did smell burned out though. I refilled the fluid and put a new cover on. This did not solve my noise problem though.
Is it still the rear differential that is making the noise? Is it something else? How hard is it, and how involved is it to replace the rear differential? Can I replace its components, and which ones?
Toyota :: 1989 - Grinding Noise Coming From The Brakes
I replaced the pads and rotors on my 1989 toyota camry yesterday. Took it out for a test drive and all appeared to be OK. I did not bleed the brakes, but did have to remove a small amount of brake fluid after installing everything.
On my way into work this morning there was quite a bit of grinding noise coming from the brakes. The noise was not consistent, happening both while brakes were depressed and also when not in use. It also would go away after a few minutes and didn't always happen while braking.
I'm thinking the piston may be locking up at times, but don't know. I'll also throw out there that this is my first brake job. I did follow my Haynes manual and don't think I did anything wrong.
Ford Ranger / B-Series :: 1989 - Grinding Noise When Let Off Gas
I have a 89 Ranger, 2.3, 2wd, Mazda 5 spd. Last year, 10,000 miles ago, I replaced the clutch, pressure plate, slave cyl, and pilot bearing. Today, it started making a terrible grinding sound/vibration when you let off the gas. The noise is coming from the clutch/transmission area. It is so bad that any amount of "engine braking" sounds terrible and I have to press the clutch in and the noise immediately stops. What to check for?
The only thing I can think of off the cuff is
1) bad pilot bearing,
2) low/no tranny oil. I replaced the oil and put silicone on the known leaky spots while I had the tranny out,
3) Input shaft had some "wobble" in it when I had the tranny out to replace clutch 10,000 miles ago.
This could be it but why would it start 10k miles later?
Sierra :: 2002 - Alternator Started To Make Some Noise And Battery Light Flashing
I have a 2002 with a 4.8 ... My alternator started to make some noise, and my battery wasn't holding a charge very well so i decided to change the alternator today before it went some were out in the boonies. After i put the new alternator in, the battery light started flashing in the "message center" but everything seems to be running fine. The voltage gauge in the dash is reading about 15. So from there I turned everything on in the truck and the gauge barely dropped. At this point I'm not sure what to do, I'm going to put the old one back on and see if it goes out, oh I also put some tension on the belt to make sure it wasn't slipping.
View 3 RepliesRegal :: 1989 Buick Making Grinding Noise When Accelerate
My 1989 Buick Regal is making a grinding sound when I accelerate. It makes the sound slightly when it's just idling as well, but it definitely gets worse when I start going. It's been dying a bunch too. The engine will just shut off. The scariest part though, is when I pop the hood and have a look, there are shards of metal that I can only assume have been ground off, thus the grinding noise. It's near the belt, but that's all I really know because I'm not car smart at all.
View 2 RepliesVolvo :: 1989 740 Turbo Wagon Won't Start - No Noise From Fuel Pump
I recently bought this car in its current no start condition after sitting 3 years. Initially I jumped it off and it just cranked, no attempt to start and no noise from either fuel pump.
I checked the fuses and the fuel pump relay behind/under the radio and it clicked and was dated 2006 so it had been replaced. I assumed it was replaced when the under car fuel pump was replaced at it was a replacement.
I sprayed a little starting fluid and it fired right up and ran until used up.
I ordered both pumps and strainer and installed the under car pump earlier this week. The in tank pump and strainer looked horrible and original. There was a small issue with the return line on the in tank fuel pump sending unit when I removed it that required brazing which I got back from the shop today.
This afternoon I installed the in tank pump & strainer on the sending unit and installed all that stuff. I spliced in a quick disconnect in the wiring harness for easy separation/installation next time.
Jumped the car again [yeah needs a battery] after everything was hooked back up and no in tank pump heard with key on to prime several times and no start although I hear the under car pump quit after attempting to start and they turned off.
Is there any other fuse/relay to check? If the under car fuel pump is evidently working, wouldn't it pull fuel without the in tank pump coming on? There's about 3 gallons in the tank. I'm going to test if there's current to the in tank pump tomorrow.
GMC - Sierra :: 2000 - Violent Popping Noise On Passenger Side And Truck Simply Slowed To A Stop
Son's 2000 GMC Sierra, 200000 miles, 4.8L engine, automatic transmission and 4WD. Was driving home from a trip to the store - heard a "violent popping noise" on the passenger side and the truck simply slowed to a stop. Engine running fine, all sounds fine while idling. When we put it into any gear, I can "feel" it go into gear but the truck doesn't move forward or back. Just changed differential, transfer case, and transmission fluids about two months ago.

If you put your ear to the steering wheel, does everyone's MFI make a buzzing noise? Kinda like a computer screen noise. Just seems a bit excessive to me, but maybe that is just how they are.
