SOURCE: need to replace 1991 chevy astro van break pads

The following procedure requires the use of a C-clamp and slip-joint lock pliers.

  1. Siphon off about 2/3 of the brake fluid from the master cylinder reservoirs.

CAUTION The insertion of thicker replacement pads will push the piston back into its bore and will cause a full master cylinder reservoir to overflow, possibly causing paint damage. In addition to siphoning off fluid, it would be wise to keep the reservoir cover on during pad replacement.

  1. Raise and support the front of the vehicle on jackstands. Remove the wheels.
When replacing the pads on just one wheel, uneven braking will result; always replace the pads on both wheels.
  1. Install a C-clamp on the caliper so that the frame side of the clamp rests against the back of the caliper and so the screw end rests against the metal part (shoe) of the outboard pad.
  2. Tighten the clamp until the caliper moves enough to bottom the piston in its bore. Remove the clamp.
  3. Remove the 2 Allen head caliper mounting bolts enough to allow the caliper to be pulled off the disc.
  4. Remove the inboard pad and loosen the outboard pad. Place the caliper where it will not strain the brake hose; it would be best to wire it out of the way.
  5. Remove the pad support spring clip from the piston.
  6. Remove the 2 bolt ear sleeves and the 4 rubber bushings from the ears.
  7. Riveted style brake pads should be replaced when they are worn to within 1/32 in. (0.8mm) of the rivet heads; bonded style pads should be replaced when they are worn to no less than 1/32 in. (0.8mm) of the backing plate.
  8. Check the inside of the caliper for leakage and the condition of the piston dust boot.
To install:
  1. Lubricate the 2 new sleeves and 4 bushings with a silicone spray.
  2. Install the bushings in each caliper ear. Install the 2 sleeves in the 2 inboard ears.
  3. Install the pad support spring clip and the old pad into the center of the piston. You will then push this pad down to get the piston flat against the caliper. This part of the job is a hassle and requires an assistant. While the assistant holds the caliper and loosens the bleeder valve to relieve the pressure, obtain a medium pry bar and try to force the old pad inward, making the piston flush with the caliper surface. When it is flush, close the bleeder valve so that no air gets into the system.
Make sure that the wear sensor is facing toward the rear of the caliper.
  1. Place the outboard pad in the caliper with its top ears over the caliper ears and the bottom tab engaged in the caliper cutout.
  2. After both pads are installed, lift the caliper and place the bottom edge of the outboard pad on the outer edge of the disc to make sure that there is no clearance between the tab on the bottom of the shoes and the caliper abutment.
  3. Place the caliper over the disc, lining up the hole in the caliper ears with the hole in the mounting bracket. Make sure that the brake hose is not kinked.
  4. Start the caliper-to-mounting bracket bolts through the sleeves in the inboard caliper ears and through the mounting bracket, making sure that the ends of the bolts pass under the retaining ears of the inboard shoe.
  5. Push the mounting bolts through to engage the holes in the outboard shoes and the outboard caliper ears and then threading them into the mounting bracket.
  6. Torque the mounting bolts to 37 ft. lbs. (50 Nm). Pump the brake pedal to seat the linings against the rotors.
  7. Using a pair of slip-joint locking pliers, place them on the notch on the caliper housing, bend the caliper upper ears until no clearance exists between the shoe and the caliper housing.
  8. Install the wheels, lower the vehicle and refill the master cylinder reservoirs with brake fluid. Pump the brake pedal to make sure that it is firm. If it is not, bleed the brakes.

SOURCE: How to replace a heater core in a 1994 chevy 1500

As with all vehicles it seems the first part that they build around is the heater core. It is under the dash above the floor housed in a black plastic sealed box. Sealed with goop. Locate that box and start removing everything around it that is peventing taking the cover off. Of course disconnect the heater hoses under the hood a thefirewall.

Warning it is never as easy as it sounds.

Either you have bad weather stripping in one of the doors, or a bad heater core. Check all the stripping around the doors, and windshield. Does the car have heat?

Need to replace heater core on 1997 Chevy Lumina


If it is necessary to remove the heater assembly, the cooling system must be drained before removing the heater core.
When a heater core leaks, a new heater core is installed or the old one repaired.
Heater Housing
  • The heater housing is usually under the dash and must be removed to gain access to the heater core.
  • Procedures for replacing the heater core vary with the year, make, and model of car. It threfore necessary to consult the manufacturer's repair manuals for the proper procedure for replacement.
f74-01.gif The heater housing is disassembled to get to the heater core. Heater Core
  • Remove the access panels(s) or the split heater/air conditioning case to gain acess to the heater core.
  • Remove the heater coolant hoses.
  • Remove the cable and/or vacuum control lines (if equipped).
  • Remove the heater core securing brackets and/or clamps.
  • Lift the core from the case. Do not use force. Take care not to damage the fins of the heater core when removing.
  • To reinstall the heater core, reverse the removal steps.
When the heater core leaks and must be repaired or replaced, it is a very difficult and time-consuming job primarily because of the core's location deep within the firewall of the car. For this reason always leak test a replacement heater core before installation.

Need to chang a heater core in this van its a 92 lumana apv


Disconnect the inlet and outlet pipes on the upper right side of the firewall (Its somewhat of a long reach but you can do it) Drain the radiator and then remove the heater core. Its inside the van located in the heater box under the passenger side of the dash board. I believe you may have to remove the inner glove box. I know that is the case on the TransPort and the Silhouette but the Lumina dash is somewhat different in style.

Replacing a heater core


YOU DO NOT NEED TO REMOVE THE DASH BOARD. IT WILL BE BEHIND THE GLOVE BOX. LOOK UNDERNEATH THE DASH AND YOU WILL NEED TO REMOVE A PANEL TO GAIN ACCESS TO THE HEATER CORE. THE PANEL WILL BE ABOVE THE PASSENGERS FEET ON THE FIREWALL.
