2005 Buick LesabreMy car suddenly made a high pitched squealing noise while moving. It felt like it was coming from steering wheel area But eventually grew to metal grinding noise sort of metal on metal then grinding gear like fly wheelish… Car has had lots of work, transmission is warranted – not labor, crv?

Don’t know need some ideas so I can take it to warranty place or ignore it, brakes have 13k on it and no chirping ever heard or. Felt


RESPONSE

Metal Grinding Noise

The first place to look for a metal on metal noise would be the brakes. This is the most common place for a metal on metal noise. It is normal for brakes to make a squealing noise before it turns into a metal grinding noise when there is a brake related issue. It is possible that you have a sticking brake caliper that has caused premature wear of the brake pads.

1998 Buick CenturyHow do I re-install the pulley on the harmonic balancer?


RESPONSE

First of all on this engine the pulley is part of the balancer. They are meant to be one unit. There is a rubber insert between the pulley and the outside of the balancer. As a result there is no way to re-install the outside pulley once it comes apart as it is a balanced unit. In conclusion a new replacement should be used if damage is found on the harmonic balancer.

Replace Harmonic Balancer

Removal

 The inertial weight section of the crankshaft balancer is assembled to the hub with a rubber type material. Therefore the correct installation procedures (with the proper tool) must be followed or movement of the inertial weight section of the hub will destroy the tuning of the crankshaft balancer.

  • Remove the drive belt.
  • Raise and suitably support the vehicle.
  • Remove the right front tire and wheel.
  • Take off the right engine splash shield.
  • Remove the crankshaft balancer bolt and the washer.
  • Remove the crankshaft balancer. Use a Balancer Puller.

Installation

    1. Apply sealant to the keyway of the balancer, this is especially relevant. Use sealant GM P/N 12345739 or equivalent.
    2. Install the crankshaft balancer. Use the J 29113/66515 .

    1. Remove the J 29112/66515.

harmonic balancer installation 1998 Buick CenturyCaution!First of all use the correct fastener in the correct location. Replacement fasteners must be the correct part number for that application. In addition the fasteners requiring replacement or fasteners requiring the use of thread locking compound or sealant are identified in the service procedure. Do not use paints, lubricants, or corrosion inhibitors on fasteners or fastener joint surfaces unless specified. These coatings affect fastener torque and joint clamping force and may damage the fastener too. Most of all use the correct tightening sequence and specifications while installing fasteners in order to avoid damage to parts and systems.

  • Install the crankshaft balancer washer and the bolt.

Tighten
Tighten the crankshaft balancer bolt to 103 N·m (76 lb ft).

  • Install the right engine splash shield.
  • Install the right front tire and wheel.
  • Lower the vehicle.
  • Install the drive belt. Refer to Drive Belt Replacement.

1988 Buick Park AvenueI was looking at this car to buy it. When I went to drive the car, it was sitting in park at idle and I noticed a large amount of shaking. So I drove it up the road and the shaking stayed. I never drove over 35 mph. But I’d like to know whats causing the shaking before I consider buying it.


RESPONSE

Most likely there is a misfire in the engine causing the shaking. May be as simple as just needing a good tune up or could a burnt valve. Hard to say without doing some diagnosing.

Buick RegalI have a 1996 Buick Regal. Until recently, it’s ran fine. And then, this past Sunday (as of the time of this post), the RPMs began to shoot up to 5 and 6 and the car lost acceleration. I thought it needed more transmission fluid, but today I found out that I had put too much in it. So my dad and I drained the pan and refilled it, but the car refused to go into gear. Let me rephrase — it would go into gear, but it wouldn’t go anywhere. I found several posts on various sites about how it might be a transmission pump or a transmission lockup solenoid, but the results upon testing them were still the same — no acceleration at all. Does anyone know how this can be fixed without the need for a mechanic?


RESPONSE

If the fluid was burnt looking it will need rebuilt. If you hear a whining noise it is the pump.  If the fluid was pretty new looking then it is most likely an electronic solenoid sticking. This will generally set a code. The check engine light will not illuminate as it has to do with the transmission and not the engine. You will need a scan tool in order to pull the transmission codes. The codes will help point you in the right direction. Not much to do without the codes. Feel free to post them below if you have further questions related to this issue.

Fuel Filter Replacement

Removal Procedure

Important 

   •  There is no service interval for fuel filter replacement. Only replace the fuel filter if the filter is restricted.
   •  Inspect the fuel tank internally and clean the fuel tank if you find a restricted fuel filter.

  • Relieve the fuel system pressure.
  • Raise the vehicle.
  • Disconnect the quick-connect fitting (4) at the fuel filter inlet.
  • Disconnect the threaded fitting at the fuel filter outlet.
  • Drain any remaining fuel into an approved gasoline container.
  • Remove the fuel pipe O-ring.

Installation Procedure

  • Remove the protective caps from the new fuel filter.
  • Install the new plastic connector retainer on the fuel filter inlet. Install the new retainer in the same position as on the old fuel filter.
  • Lubricate the new fuel pipe O-ring with clean engine oil.
  • Install the fuel pipe O-ring.
  • Slide the fuel filter into place.
  • Connect the quick-connect fitting (4) to the fuel filter inlet.

Caution! Use the correct fastener in the correct location. Replacement fasteners must be the correct part number for that application. Fasteners requiring replacement or fasteners requiring the use of thread locking compound or sealant are identified in the service procedure. Do not use paints, lubricants, or corrosion inhibitors on fasteners or fastener joint surfaces unless specified. These coatings affect fastener torque and joint clamping force and may damage the fastener. Use the correct tightening sequence and specifications when installing fasteners in order to avoid damage to parts and systems.

  • Connect the threaded fitting to the fuel filter outlet. Use a back-up wrench in order to prevent the fuel filter from turning.

Tighten
Tighten the fuel filter fitting to 30 N·m (22 lb ft).

  • Lower the vehicle.
  • Tighten the fuel tank filler pipe cap.
  • Connect the negative battery cable.
  • Inspect for fuel leaks.
  1. Turn ON the ignition for 2 seconds.
  2. Turn OFF the ignition for 10 seconds.
  3. Turn ON the ignition .

1997 Buick Park AvenueI have a 1997 Buick Park Avenue and when I flip the switch to turn my high beams on, they don’t come on. And my dash lights and side marker lights go off also. I have replaced the switch with a new one and it didn’t fix it.


RESPONSE

Looking at the wiring diagram it would appear as the only thing in common with both the high beam switch and the dash lights would be the Lamp Control Module other than the switch.

2001 Buick CenturyI have a problem with my cooling system in my 1999 Buick Century Custom. I am leaking coolant. I tried stop leak, is not working. I can drive for long periods of time, open the radiator cap without any problem. It is cold to the touch and there is no pressure when I release the cap.


RESPONSE

Sounds like your thermostat may be stuck in the open position as well as leaking coolant. Also the radiator cap may be faulty if no pressure is building or you have a large leak. You will need to use a cooling system pressure tester.

How to find leaking coolant

  • With the engine off,  Remove the radiator cap and attach the pressure tester
  • Pump up the tester to apply pressure on the system. Pressure should be the same as the radiator cap. (around 17-20 psi)
  • Look for the leak, put cardboard underneath to help if needed. If no external leak is found, remove spark plugs and look for coolant to come out spark plug holes.
  • Repair the leak
  • Pump up the tester again
  • Watch for the pressure to hold, this indicate no more leak in the system.

Coolant Description

Caution! Antifreeze can be added to raise the boiling point of the coolant, but too much will affect the freezing point. Do not use a solution stronger than 70 percent antifreeze, as the freeze level rises rapidly after this point. Pure antifreeze will freeze at -22°C (-8°F).

GM Goodwrench DEX-COOL® was developed in order to last for 240,000 km (150,00 miles) or 5 years, whichever occurs first. Follow the instructions in Draining and Filling Cooling System . Use only GM Goodwrench DEX-COOL® or HAVOLINE® DEX-COOL® when adding or changing the coolant.

A 50/50 mixture of ethylene glycol DEX-COOL® and water will provide the following protection:

  • Give freezing protection down to -37°C (-34°F)
  • Give boiling protection up to 129°C (265°F)
  • Protect against rust and corrosion
  • Help keep the proper engine temperature
  • Let the warning lights and gauges work as they should.
