How are spark plugs replaced on Chevrolet Colorado?

The spark plugs are screwed into the head of inline engines and into the side of the V8 engines, while, in inline models, the air intake resonator must be removed to access the spark plugs. For V8 type of engines the spark plug wires should be disconnected in the following manner; one should twist and pull the wire boot while avoiding pulling the wire. Other very useful items are the special spark plug socket that has padding to protect the porcelain insulator, various form of extension, torque wrench to ensure right tightening of the spark plug and the gap checkers that are useful in determining the gaps on the new spark plugs. It is recommended to buy new plugs and pre-gap them; always replacing them one by one so that the right type of plug for the engine is acquired. After the engine cool off, remove the old plug and install the new one, inspect it for any defect and correct the gap as well. The separation is confirmed by placing an impedance probe in-between the electrodes; it must feel somewhat sticky when the wire is moved across it; slight modifications are possible by bending the side electrode. For inline engines, unscrew and disconnect the intake air resonator, then unscrew the screw and disconnect the ignition coil connectors on the valve cover and remove the bolts of each coil. On V8 engines, turn and pull the spark plug wire boots back yet do not pull the wires. Before removing it is advisable to blow through the spark plug hole with air pressure to eliminate any dirt then can use a socket and extension to remove the plugs. This should be done against a reference chart to deduce the condition of the engine and a thin layer of anti-seize compound should be applied to the threads of the new plugs; without spreading on the electrodes. Insert the new plugs by hands until they are tightened by hand then use torque wrench or ratchet to tighten the plugs while using a short piece of rubber hose while doing this to avoid cross threading. Reapply the same process to the other plugs, and after a replacement of the next steps, bolt the ignition coils as well as the air intake resonator back into place.

Chevrolet Colorado Spark Plug

The Spark Plug in Chevrolet Colorado vehicle is one of those vital components that create initial flame needed to ignite the mixture inside the combustion chamber so as to start the working of the engine. It generates a spark by providing with electricity from the ignition system into the combustion chamber to burn the fuel/air mixture. This component comprises of a metallic screw threaded outer cover, a central electrode and a ceramic insulator which is capable of withstanding high voltage of between 12000 and 45000 volts. In Chevrolet Colorado models, different sorts of spark plugs have been used such as the spark plugs with multiple ground electrodes and the surface-discharge sort of spark plugs have exemplified better ignition proficiency and sturdiness. This indicates that gap size and heat range play a very significant role in the performance of an engine and in avoiding damages. Scheduled check up and servicing of the Chevrolet Colorado Spark Plug also play a very crucial role in the reliability of the automobile as it should be inspected and maintained frequently.
