  Q: How to replace spark plugs on Chevrolet Astro?

  A:

  The V6 models produced since 1996 contain long-life platinum tipped spark plug which have a service interval of one hundred thousand miles and therefore should not be cleaned or re-gapped but if their condition looks dubious they need replacement. To reach the spark plugs they should be replaced the hood should be open, and the engine cover removed. Additional requirements always involve spark plug socket that are fitted on ratchet, several extension and a gap checker for identifying and setting of appropriate gaps on the new plugs. It may be useful to loosen the wire boots from the spark plugs with a special plug wire removal tool, although it is not necessary, and a torque wrench is advisable for re-tightening of the new spark plug. It is recommended that the different plugs be bought in advance, standardized to the right gap, and then be installed on the cars one at a time after ensuring that the right type of spark plug is gotten from the Emission Control Information label found under the hood. Remove the plugs only after the engine has been turned off for some time; while waiting for it, one should inspect the new plugs for defects and correct the gap accordingly. It is measured by a standard thickness gauge, and it should equal the figure on the emissions label; such changes should be made slowly to avoid cracking the porcelain insulator. When you are disconnecting the spark plug then pull only at the bottom of the boot and twisting is allowed. Alternatively, the removal of debris such as sand from the spark plug hole can be done by blowing compressed air or use of bicycle pump. The rear plugs can be accessed by having to remove the engine cover, and possibly the wheels and the splash guard if need be. Compared with a spark plug reference chart, you can determine the current condition of the engine during operation; after the old spark plug is pulled out, coat a little anti-seize on the threads of the new spark plug to be put in. Screw the new plug into the hole and use a torque wrench or ratchet to tighten it up and remember in the process you need to use a rubber hose to avoid the situation where you lock the threads. Last but not the least, check the condition of the spark plug wire before clamping it over the new plug and twist the boot again to secure it well, and perform all these for the other spark plugs, and when changing the plugs, do it one after the other in a sequential manner to make sure you do not mix up the wires.
