SPARK PLUG REPLACEMENT - REMOVAL PROCEDURE

how to change spark plugs in a 2005 chev colorado - 1_23_2012_5_10_32_pm.jpg

1. Remove the ignition coils (lines at end this document), then return here once you have gotten the Coil
Packs off and precede with step 2 from here.
2. Clean the spark plug recesses with low pressure air. CAUTION: Wear safety glasses
when using compressed air, as flying dirt particles may cause eye injury. NOTE:
Clean the spark plug recess area before removing the spark plug. Failure to do so could
result in engine damage because of dirt or foreign material entering the cylinder head, or
by the contamination of the cylinder head threads. The contaminated threads may prevent
the proper seating of the new plug. Use a thread chaser to clean the threads of any
contamination.
3. Remove the spark plugs from the cylinder head. NOTE: Allow the engine to cool before
removing the spark plugs. Attempting to remove the spark plugs from a hot engine may
cause the plug threads to seize, causing damage to cylinder head threads.
4. Inspect the spark plugs.

INSTALLATION PROCEDURE

1_23_2012_5_11_30_pm.jpg

1. Measure the spark plug gap on the spark plugs to be installed. Compare the measurement
to the gap specifications. NOTE:
• Use only the spark plugs specified for use in the vehicle. Do not install spark
plugs that are either hotter or colder than those specified for the vehicle. Installing
spark plugs of another type can severely damage the engine.
• Check the gap of all new and reconditioned spark plugs before installation. The
pre-set gaps may have changed during handling. Use a round feeler gage to ensure
an accurate check. Installing the spark plugs with the wrong gap can cause poor
engine performance and may even damage the engine.
2. Install the spark plugs to the cylinder head. NOTE:
• Be sure that the spark plug threads smoothly into the cylinder head and the spark
plug is fully seated. Use a thread chaser, if necessary, to clean threads in the
cylinder head. Cross-threading or failing to fully seat the spark plug can cause
overheating of the plug, exhaust blow-by, or thread damage.
• Refer to Component Fastener Tightening Notice in Service Precautions.
Tighten the spark plugs to 18 N.m (13 lb ft).
3. Install the ignition coils.

• The heated oxygen sensor (HO2S) (5)
7. Disconnect the engine wiring harness electrical connector from the intake camshaft position (CMP) sensor.
8. Carefully disengage the engine wiring harness conduit from the camshaft cover, and position aside.
9. Remove the ignition coil bolts.
10. Remove the ignition coils from the camshaft cover.

INSTALLATION PROCEDURE
1. Install the ignition coils into the camshaft cover. IMPORTANT: Ensure the ignition coil seals are properly seated to the camshaft cover.
2. Install the ignition coil bolts. NOTE: Refer to Fastener Notice in Service Precautions. Tighten the ignition coil bolts to 10 N.m (89 lb in).
3. Attach the engine wiring harness conduit to the camshaft cover.
4. Connect the engine wiring harness electrical connector to the intake CMP sensor.
5. Connect the engine wiring harness electrical connectors to the following:
• The ECT sensor (1)
• The fuel injector harness (2)
• The ignition coils (4)
• The HO2S (5)
6. Connect the engine wiring harness electrical connectors (1, 4) to the following:
• The exhaust CMP sensor (5)
• The CMP actuator solenoid valve (6)
7. Connect the engine wiring harness retainer (2) to the camshaft cover (3).
8. Connect the engine wiring harness retainers (1) to the power steering pump (2).

SOURCE: changing spark plugs

This is the 3.5L inline 5 cylinder engine. The spark plugs are at the top of the engine. They are covered by a hunk of plastic called the "Air Intake Resonator".  Remove the plastic. Carefully pull the ignition coils from the spark plugs. Unlike most other cars. The Colorado has a coil on every plug.  This boosts ignition power, but, every coil is expensive. Do not harm them.

SOURCE: how remove the rotor to change bearing for 2005

Hello, you can remove the rotor but you can't replace the bearing. Remove the tire, remove the brake caliper and use a piece of wire to tie the caliper to the frame. Don't let it hang on the brake hose or the anti-brake sensor cable. three lug bolts clip that hold the rotor to the hub. Just break this metal clips. Use a dead blow hammer (not steel) and tap the back of rotor until it turn loose on the rotor hub.


All new auto/trucks have one piece axle bearing hub that is built all together---one piece. This axle hub is bolt to the control arm hub that fit between the upper and lower ball joints. To remove the axle hub there is four bolts that hold to the control hub and this bolts are on the back of the control arm hub. This large bolts are not hard to remove with the right tools. The problem is that the axle hub (one piece) is RUSTED to the control arm hub and it is really hard to get this rust to loosen up on the hole axle hub.. I have all the tools to do this job, and still took three days to get this axle hub off. So, rcp026 I wish you lot of luck in your endeavors of this axle hub. GB...stewbison

Trying to locate spark plugs on chevy 2005 colorado, so i can replace new ones

You should see a spark plug wire for each spark plug. The spark plugs are in the cylinder head. You have to unplug the plug wire first before you replace the plugs. Be careful as to not damage the plug wires when removing them. Be carefull not to get dirt into the cylinder when replacing the plug. Do not overtighten the new plugs. I can't remember which side of the engine the plugs are on, on your truck. You truck has the inline 5 cylinder I think.
