SOURCE: replace rear axel bearing on 4x4 5.3 Litre gas engine

Loosen differential cover and let oil drain. Remove cover, remove U lock from axel. Pull axel out. Remove bearing seal then bearing. Install new bearing, seal and reinstall axel. Reinstall U lock and new cover gasket. Fill with 75-90wt gear oil. Now I know that sound pretty straight forward. But there are some things to remember. The U lock can be difficult to remove sometimes. The most important thing is the seal, you will need to make sure it gets seated correctly and not torn when installing axel.

SOURCE: Heating System

The Engine Coolant Temperature (ECT) sensor is mounted in the intake manifold and sends engine temperature information to the ECM. The ECM supplies 5 volts to the coolant temperature sensor circuit. The sensor is a thermistor which changes internal resistance as temperature changes. When the sensor is cold (internal resistance high), the ECM monitors a high signal voltage which it interprets as a cold engine. As the sensor warms (internal resistance low), the ECM monitors a low signal voltage which it interprets as warm engine.

See Figures 3 and 4

  1. Remove the ECT sensor from the vehicle.
  2. Immerse the tip of the sensor in container of water.
  3. Connect a digital ohmmeter to the two terminals of the sensor.
  4. Using a calibrated thermometer, compare the resistance of the sensor to the temperature of the water. Refer to the engine coolant sensor temperature vs. resistance illustration.
  5. Repeat the test at two other temperature points, heating or cooling the water as necessary.
  6. If the sensor does not meet specification, it must be replaced.

SOURCE: How to replace the thermostat on a 1989 GMC Sierra

The thermostat is located on top of the engine, under
the upper radiator hose. Put a drain pan under the front of the engine, Loosen the clamp on the hose at
the eng. Twist the hose from side to side to break it
loose.(it may be a little stuck) Slowly remove the hose and let drain. Remove the 2 bolts that hold the
thermostat housing,( 1/2" socket or wrench)remove housing. Next, remove thermostat (it may be in the housing) and scrape off the old gasket and sealant.
On the inside of the housing you will see a groove
around the hose inlet, put a little sealant in the groove
to help hold the therm. in place. Install the thermostat
into the groove, with the copper sensor facing out.
Put a little sealant around the mounting surface on
the housing and put the gasket in place, let the
sealant set up for about 15 minutes. Replace the
housing making sure the thermostat stays in the
groove, if it gets dislodged and pinched between the
housing and block, you may break the housing when
you tighten it down. Replace the hose fill with coolant. Before you replace the housing fill the block
with coolant, this will help purge the air from the system. I should have said that a paragraph ago.
I hope this helps you.

Temperature fluxuates up and down, just replaced thermostat and repaired a kinked hose to the heater core. 1998 GMC v6 4.3L

If this just started happening after replacing the thermostate then your thermostate is just opening then closing.Not staying open to maintain a seady temp. Your fan clutch may be going bad and not adjusting fan speed acordingly either.

2000 gmc sierra 5.3l heater does not get hot

After replacing the thermostat I pulled the heater hoses off and blew air through the heater core at firewall. Can only blow in left side as directional valves will prevent opposite. Chunks of stuff came out with coolant. I then put a piece of hose on the left side and shot water through until it came out clear.
Put it all back together and heat works fine.

No Heat

You need to verify the blend door is operating and the heater core is not plugged or coolant flow to it is restricted.
