Pontiac - Grandprix :: Car Sounding Like There Is Metal In The Pistons And Belts Jumping Off


Apr 28, 2015

So the other day I was driving the car and it was working fine, shut it off and turned it on like 4-5 times that day as I was driving around, then I went to check the muffler and when I started it it sounded like someone jammed a bunch of metal shavings in the engine. The engine is completely fine and there is nothing in it I know that for a fact, and the fact that the belt keeps jumping off is a def pointer that its something to do with a pulley. My friend thinks its the tensioner pulley because its jumping like crazy when the engine is running but the sound is horrid.

'm gonna have a friend come look at it tomorrow after work. Also, my friend snapped the bottom bolt on the power steering pump and i left the broken piece in and I always heard it rattling and it was bent when I checked cuz I thought that's what was making the sound. So that popped out enough to hit the pulley and bend what was left of the bolt down. I spun each pulley and I didn't hear any sounds, and I tried to shake them and none felt loose. Its got 130k on it but still, 1 problem after another after another. Could that broken bolt that came out and hit the pully possibly jarred it off balance or something? If the tensioner pulley isn't broken then something is making the belt stop because its pulling it down periodically. What I should look for to fix it.

Ford Excursion :: Brakes Sounding Like Metal On Metal

The brakes were sounding like metal on metal. Three wheels in, some of the pads needed replaced but none were worn out. I got to the right rear wheel and the inside pad is worn to the bracket but the outside pad hardly looks worn at all.

I'm already replacing rotors, pads and calipers (I wasn't going to replace the rear rotors or calipers until I got to this wheel). Is there anything else I need to check because of such uneven pad wear?

Santa Fe (CM - 2007-12) :: Metal Sounding Rattle From Back

I have a metal sounding rattle coming from the back of the vehicle. It sounds like it is coming from the hatch area. I removed all loose things (jack) and the noise is still there.

I checked the license plate and put foam behind it, I wrapped the latch with a layer of tape. The noise seems a bit better but still there when on rough roads.

Pontiac - Grandprix :: EGR Clicks On And Off Every Other Second

Engine starts then runs for a period of time until it warms up, then fans come on and then EGR clicks on and off every other second , then it eventually quits. Replaced the coolant temp sensor. And it never sets a code. Have checked wiring for shorts and nothing. Is it a ECM going bad??

Pontiac - Grandprix :: 2002 - Air Conditioner Putting Out Hot Air

Hottest day ever on Planet Earth and my air conditioner in my Pontiac decides to throw hot air in my face! Luckily, for my female companion, she gets ice cold air. This 2002 Grand Prix 40th Anniversary edition has 236,000 miles, I never once had a problem with the air conditioner in the past (have thought about contacting GM asking what they did right in this car)This model has dual climate control. I noticed that in turning the selector knob on the dash climate control panel, there is hot air in the vent, bi-level, heater and defrost, but cold air comes out on the passenger side. The interior temperature functions are all similar on the '97 through '03 models of Grand Prix, just wondered if this is something I can fix, or do I need to visit a Pontiac dealer to have it diagnosed (and spend a lot of money)

Pontiac - Grandprix :: Code P0741 - TCC Stuck Off

Code is for tcc stuck on. Code p0741 is tcc stuck off. So, it's a sticky solenoid. Which means it may start out sticking occasionally and progress to sticking more often and finally staying on/off permanently? If u get the code/symptoms 1 time, does it usually mean it will happen again, soon?

Pontiac - Grandprix :: Overheating And Antifreeze Smell

We were driving home yesterday and all of the sudden the car started to over heat and we could smell antifreeze. We turned the ac off and put more water in it. Today we just had to make a short trip somewhere (we were planning on having it looked at first thing Monday morning). The temperature gauge never showed it overheating but as we pulled into our driveway we heard a knocking sound and it just shut off. Iit may just be a leak and it caused the car to over heat??

Pontiac - Grandprix :: 2001 - Banging On Gas Tank

We have a grand prix and had the water pump replaced. Soon after this the fuel pump went out. We replaced it 2 more times within a few weeks. Bought another one and this time the car may have run a period of 4 to 5 months before it went out. We have found by banging on the gas tank, and by turning the car on while someone bangs on it, you can hear the pump come on and start the car. Well, once again this week we have had the pump changed and I was about to leave work and the car would not start. Banging on the tank allowed me to be able to start the car... What is going on with the pumps or what is making them go out...???

I took of the handle panel on the exterior of the car to adjust the rod so the door would open easier. NOW THE DOOR WONT OPEN AT ALL!

Its a 1995 Pontiac Grand Prix SE.

I've tried removing the door panel from the inside, but it seems useless because the retarded vertical handles cant even be accessed from the door panel.

Pontiac - Grandprix :: Low Coolant Light Comes On Occasionally

I have a 97 Grand Prix GT with a 3800 engine. The "low coolant" light comes on occasionally, I checked the coolant in the radiator and reservoir, both are fine. I replaced the radiator cap. There are no signs of engine overheating. Could it be the thermostat? Also where is the sensor located?

Pontiac - Grandprix :: Pulsing / Growling ABS At Low Speed

When coming to a full stop, there is a growling/grinding sound from beneath the floor behind the brake pedal and I can feel the growling./grinding in the pedal as well. Used to happen occasionally, now is happening more often than not. When the Service ABS System/Service Traction System message is displayed (occasionally) on the message center, the growling/grinding doesn't occur and the brakes work. Like normal. When I turn the car off and restart it, the messages are no longer displayed and the growling/grinding sound and feel returns.

Pontiac - Grandprix :: 1998 - Acceleration Out Of Control

Concerning cars accelerating out of control. I have a 98 pontiac gtp. The garage has not checked out the cable yet. They were thinking it was something else. Thought they had it fixed. Still not fixed. Every time I step on the gas to go into passing gear at any speed the accelerator stay on. I have found nothing to get out of the situation except back the key off one click. Acceleration stops. I still have power steering and brakes. Then I shift into neutral and restart it while I am still going down the road. I can make the car stick on every time with out fail. It only happens when I press the peddle all the way down at once. Very dangerous to drive. I drive it because I know not to go into passing gear and how to come out of it if it does stick on. Turning it one click shuts off your head lights too. Found that out when I got it back and was driving after dark, after the garage thought it was fixed, and got to experience panic of not being able to see for a moment. I unplugged the cruise and pulled the fuse on it a long time ago thinking that was the problem. Could it be the throttle body or cable? If it is the cable why does it go back to normal right away when I click the key off one click and put it in neutral and restart it fine.
