2002 Chevy TrailblazerI have a battery light on and when engine is off and keys in pocket still have a dim battery light.

RESPONSE

The battery light comes on when the alternator is no longer charging the battery. An internal diode has failed inside your alternator. Replacing the alternator should take care of the battery light.

Charging System Indicators

 BATTERY

The IPC illuminates the battery indicator when the following occurs:

  • The PCM detects that the generator output is less than 11 volts or greater than 16 volts.  IPC receives a class 2 message from the PCM requesting illumination.
  • The IPC determines that the system voltage is less than 11 volts or greater than 16 volts.  IPC receives a class 2 message from the body control module (BCM) indicating the system voltage.
  • The IPC performs the displays test at the start of each ignition cycle. The indicator illuminates for approximately 3 seconds.
  • The ignition is on, with the engine off.

BATTERY NOT CHARGING

The IPC illuminates the battery not charging indicator in the driver information center when the following occurs:

  • The PCM detects that the generator output is less than 11 volts or greater than 16 volts.  IPC receives a class 2 message from the PCM requesting illumination.
  • The IPC determines that the system voltage is less than 11 volts or greater than 16 volts.  IPC receives a class 2 message from the body control module (BCM) indicating the system voltage.

2001 Chevy CavilierI have hid headlights my friend took out of his Prelude and gave to me. I would like to know if it’s possible to install them in my Chevy Cavalier 2 door coupe base 2.4L, (which currently has regular stock headlights installed). and if so, what do I need to do?

RESPONSE

HID headlight bulbs require a special ballast to operate. You will need them on order for your HID bulbs to work properly. They can be purchased at a reasonable cost. Another thing to consider would be if the bulbs will actually fit your vehicle bulb socket.

2014-Chevy MalibuThe stop start system wasn’t working due to bad auxiliary battery. The Chevrolet dealership replaced the battery and drove 17 miles to road test and monitor the system to see if it was operating properly. Isn’t seventeen miles a lot of driving just to road test something that should activate within a short period of time? on the city streets, the environment for which the system was designed, that would be about 90 minutes of driving. seems like way too much mileage?
Thanks
John

RESPONSE

One could argue that is an excessive amount of mileage and time. Most only get 5 minutes if they are lucky. You received and over and beyond amount of time. Some would argue that you were lucky to have it tested to such great length. Seems like if you were charged and extra 1 1/2 labor, I could see why you might be upset. If you didn’t get charged, smile and say thank you.

There is a specific Relearn procedure for the battery sensor module that must be carried out when replacing the battery. There may be an extra amount of driving involved.

Calibration Criteria

Note: This procedure is only for vehicles equipped with a Battery Sensor Module. Attempting to run this procedure without a Battery Sensor Module may cause unwanted results. If this occurs, the BCM will need to be reset with an ignition cycle.

The B110 Battery Sensor Module provides primary battery voltage and current data to the Engine Control Module (ECM). The ECM uses a Battery State Estimator algorithm to determine the state of charge of the primary 12 volt battery for use in controlling the stop/start feature. The battery state estimator monitors the voltage differences between the ECM and B110 Battery Sensor Module and current differences between the battery current sensor and the B110 Battery Sensor Module .The B110 Battery Sensor Module learn procedure must be performed after either the battery has been replaced or charged with an external battery charger.

Calibration Procedure

  1. Apply the parking brake.
  2. Ignition ON, engine OFF.
  3. Install a scan tool.
  4. Clear all DTCs before proceeding.
  5. Navigate to the Configuration/Reset Functions menu of the BCM.
  6. Select the Battery Sensor Module procedure and follow the directions displayed on the screen.

1952 Chevy Styleline Engine RemovalHow do I disconnect the engine from the transmission in my 1952 Chevy Styleline Deluxe. Need help with engine removal.

RESPONSE

Engine Removal

Disconnect all electrical wiring that includes wiring harness, etc. Remove radiator. Remove engine fan assembly so you don’t bend it on removal.  Support the engine with an engine hoist. Support the transmission from underneath or it will want to drop. Remove the retaining bolts from the Engine mounts in addition to the transmission bell housing. Remove torque converter blots and starter. Lift engine with hoist just enough to clear the mounts. Adjust transmission support. Finally, wiggle engine and pull away from transmission.

Engine Knocking Noise 2006 Chevy Equinox

2006 Chevy EquinoxI have an engine misfire when engine is cold. If its put into reverse with foot on brake, you can hear a knocking noise that stops after engine warms up. Thanks.

RESPONSE

A consistent engine misfire will eventually cause the check engine light to illuminate. Once the check engine light has come on and stays on the first step would be to pull the engine trouble codes. These Engine trouble codes will indicate the exact cylinder that is having the issue. This will make it easier on the wallet instead of throwing parts at it.

A knocking noise is not good. If it is being caused as a spark knock it may be as simple as contaminated fuel. Once the engine warms up the knock sensor is able to correct the engine timing and prevent the engine knocking noise. Once the fuel tank is below half full try filling up at a different fueling station with the Highest octane available. This will mix with the fuel already in the tank and raise the octane level. You may need to do this the next couple of fill ups. I think this would be the best first course of action.

Internal Engine Knocking Noise

Rod knocking is referring to the engine rod bearings falling. This causes an engine knocking noise that generally will get louder when the engine is revved. Normally will become more pronounced once the engine is warm. I do not think this is the case with your engine but thought I would share for other readers.

A Main bearing knocking noise refers to the engine cranks main bearings failing. With the main bearing failure the knocking is more pronounced at engine idle. The engine knocking noise will tend to go away when the engine is revved. Normally will become more pronounced once the engine is warm. Again, I do not think this is the case with your engine but thought I would share for other readers.

 

 

Hydraulic Clutch 2002 Chevy Cavalier

2001 Chevy CavilierIt lets me shift from first to second but no other gears. Can I bleed my clutch or do I need a whole new clutch kit?

RESPONSE

If in neutral with the engine off you are able to shift into all gears then you will need to replace the hydraulic clutch assembly and possibly the clutch slave cylinder assembly. If you are still unable to shift into all gears, there is internal transmission damage.

Hydraulic Clutch System Description and Operation

Clutch Spin Down Time

Check the clutch spin down time as follows:
•Apply the parking brake. Block the vehicle wheels.
•Shift the manual transmission into neutral.
•Start the engine. Run the engine at idle speed.
•Engage the clutch.
•Disengage the clutch. Wait 9 seconds.
•Shift the transmission into reverse.

Clutch Driving Members

The clutch driving members are 2 flat surfaces machined to a smooth finish. They are:
•The rear face of the engine flywheel
•The front face of the clutch pressure plate

Clutch Driven Members

The driven member is the clutch driven plate. The clutch driven plate has a splined hub. The splined hub slides lengthwise along the splines of the input shaft. The splined hub drives the input shaft through these same splines. The driving and driven members are held together with a spring pressure. This pressure is exerted by a diaphragm spring in the clutch pressure plate.

Hydraulic Clutch Fluid

Caution! Do not use mineral or paraffin-base oil in the clutch hydraulic system. These fluids may damage the rubber parts in the cylinders.

Hydraulic Clutch Operating Members

The clutch system consists of the following components:
•A master cylinder with a reservoir
•A switch
•An concentric slave cylinder connected to hydraulic tubing
•Pressure Plate
•Clutch Cover
•Diaphragm Springs
•Release Bearing
•Clutch Disc
•Torsional Springs
•With the depression of the clutch pedal, the clutch master cylinder becomes pressurized from the force of the push rod into the master cylinder. This forces hydraulic fluid into the tubing from the master cylinder to the concentric slave cylinder. The concentric slave cylinder then engages by pushing the releasing bearing into the diaphragm spring and release the clutch. A hole in the cowl panel accommodates the master cylinder. A quick connect coupling helps route the hydraulic tubing. the concentric slave cylinder is inside the transmission and on the input bearing retainer. The hydraulic control system can be replaced without having to gain access to the clutch system internal components , simply engage the quick connect coupling mounted through the transmission housing. No adjustments to the clutch system are necessary. as the clutch wears, the fluid level in the master cylinder reservoir changes to compensates for clear wear. A new system will have fluid in the reservoir. An electrical switch on the push rod has two functions: One function is a clutch interlock, ensuring the engine does not start unless the clutch pedal is engaged, positioned to the floor. The second function is to cut off the cruise-control system, if equipped, when the clutch pedal is engaged.

2002 Chevy TrailblazerFront brakes engage while driving at any speed mainly hwy

RESPONSE

Sounds like you may have a sticking brake caliper. The brake would tend to drag and become worse the longer you drive. It would not be as noticeable when first driving until it has a chance to heat up and expand. Your vehicle is equipped with ABS. Is the ABS light on? If the ABS light is illuminated there may be an issue with your hub bearing failing. This is quite common.

Disc Brake System Description and Operation

System Component Description

 The disc brake system consists of the following components:

Disc Brake Pads: Applies mechanical output force from the hydraulic brake calipers to friction surfaces of brake rotors.

Disc Brake Rotors: Uses mechanical output force applied to friction surfaces from the disc brake pads to slow speed of tire and wheel assembly rotation.

Disc Brake Pad Hardware: Secures disc brake pads firmly in proper relationship to the hydraulic brake calipers. Enables a sliding motion of brake pads when mechanical output force is applied.

Disc Brake Caliper Hardware: Provides mounting for hydraulic brake caliper and secures the caliper firmly in proper relationship to caliper bracket. Enables a sliding motion of the brake caliper to the brake pads when mechanical output force is applied.

System Operation

 Mechanical output force is applied from the hydraulic brake caliper pistons to the inner brake pads. As the pistons press the inner brake pads outward, the caliper housings draw the outer brake pads inward. This allows the output force to be equally distributed. The brake pads apply the output force to the friction surfaces on both sides of the brake rotors, which slows the rotation of the tire and wheel assemblies. The correct function of both the brake pad and brake caliper hardware is essential for even distribution of braking force.

2000 Chevy SilveradoRepair cause of oil leak at oil filter block leading to radiator.

RESPONSE

The leak is coming from the Engine Oil Cooler block. You will need to remove the two retaining bolts from the cooler block and replace the gasket. This is a common gasket failure.

Engine Oil Cooler Description and Diagram

The oil cooler is located in the left side of the radiator. Engine oil flows through the cooler and reduces the temperature of the engine oil. The cooled engine oil then returns to the engine.
