GMC 19329681 Shield,Spark Plug Wire

Spark plug wires should be inspected at the prescribed service interval and always when the spark plugs have been replaced in the engine. Some models for example the 4.3L V6, 5.0L V8, 5.7L V8, 7.4L V8 contain spark plug wires that runs from the plug to the distributor whereas models like 4.8V V8 models, 5.3V V8 and 6.0 L V8 contain individual coils for each cylinder so they will only contain short plug wires. For access, loosen the front wheel lug nuts and then chocks the vehicle on a jack stand, then pull off the wheels and inner fender splash shields. Initially, perform a surface check using the engine while running with your lights off identifying those spark plug wires which arc or spark. A plug wire can be disconnected simply by holding firmly the rubber boot on it and twirling it and pulling it downward without having to hold the wire. Inspect the corrosion on the inside of the boot making sure that it gives a perfect fit on the spark plug; Trim the metal connector if it has been laid back in order to make a perfect connection. Using a rag wipe the wire down, ensuring that it isn't bent too many times or otherwise damaged. Remove a wire from the distributor cap or coil, inspecting the corrosion and proper fit before reconnecting the wire. Perform the same process on all spark plug wires making sure they are properly connected. If new wire is required it is recommended to get a set of wires appropriate for the particular model of the engine, connect them one at a time restoring the firing order and ensuring the right wire path. In case of the engine has a distributor, then, using a wrench, unscrew the distributor cap screws and lift the cap up while still connected to the wires and then examine the rotor for crack or any sign of wear and if, then replace it. The rotor has to be fitted accurately so that the internal key has to fit into the slot provided in the shaft. Check distributor cap for signs of wear and rust, if it is worn or rusty replace it, after that apply silicone dielectric grease around any terminal before the cap is reinstalled. Carefully connect the spark plug wires to the new cap so that they don't get mixed up and then the cap back to the car then screws it down.

The spark plug wires should be checked at recommended intervals or every time new spark plugs have been fitted on the vehicle. This can be done by merely looking at the spark plug wire during the running of the engine at night or when the garage is dark and well ventilated. Turn on the engine and look at all the plug wires without having to touch any of the spinning parts. If possible try touching an insulated object on each of the wires; when the insulation is broken on a particular wire it will spark or produce a small blue flame. Because secondary ignition voltage rises with an engine speed, a faulty wire may not spark at idle; ask an assistant to rev the engine to about 2000 rpm and look for sparks again. If arcing is visible in a car, then there is need to replace all spark plug wires. To remove a plug wire, always make sure the engine is off, one must grip the bottom rubber boot and twist it slightly; when this is done do not pull on the wire but pull the wire free from the termination. Look for signs of rust within the boot and it will show a white crusty powder Also the boot needs to sit tightly on the top of the spark plug. If it is not 'snug', then disconnect the wire and squeeze the metallic tab at the end of the boot using a pair of pliers. Clean the entire surface of the wire using a clean cloth to remove dirt, grease or any kind of contaminants and then look for the presence of pinholes, carbonized zones, cracks and other form of damages on the wire such that one should not bend it to intensely. Remove the wire from ignition coil terminals pulling it vertically, then inspect the wire for signs of corrosion or tight connection before reconnecting it. Exam the remaining spark plug wires individually to make sure that are connected firmly in both ends. In case of buying the spark plug wires, get an original new set suitable for the particular model of an engine.

To ensure the proper functioning of spark plug wires, they should be regularly inspected at recommended intervals and whenever new spark plugs are installed in the engine. V6 engines have spark plug wires that go from the spark plugs to an ignition coil assembly, while V8s use a separate coil for each cylinder connected by short plug wires to its respective plug. To start, visually inspect the wires while the engine is running in a dimly lit, well-ventilated environment. Look closely at every wire to see if there is any arcing or sparking between points where it is damaged. Presence of arcing indicates the wire is broken and it should be replaced. Shut the engine off and disconnect one plug wire from one spark plug by turning and pulling gently on the rubber boot without touching any moving parts of the engine. Check inside the boot for corrosion which looks like white crusty powder. After screwing back the wire into its place around a spark plug tightly enough, wipe its entire length using a piece of cloth, inspect it for damage and prevent conductor breakage resulting from too much flexing of it. Do this in a similar way for V6 engines removing their wires from coils assembly checking for corrosion and having them securely fitted again. These procedures must also be repeated on other wires making sure that they are solidly attached both ends when latched onto each other properly. If you have to buy another set, make sure to get one specifically made for your car's engine model; replace them individually so as not to confuse cylinder firing order patterns with other firing orders.

Check spark plug wires when installing new plugs or at recommended intervals. Disconnect each wire from the plug, using a removal tool or twisting and pulling the boot. Look for corrosion inside the boot. Reattach the wire and boot to the plug, ensuring a tight fit. Clean the wire and inspect for damage. Check the wire's flexibility by bending it. Disconnect the wire at the distributor, checking for corrosion and fit. Reinstall the boot or ring onto the distributor. Repeat for all wires. In a dark garage, visually check for arcing or sparks while the engine runs. If needed, buy new wires specific to your engine model and replace each wire one by one to maintain the firing sequence.

Distributorless ignition systems are equipped in these models. The spark plug wires get connected directly to the ignition coils. For many V6 engines (excluding 3.4L), rotating the engine may be required to access the rear spark plugs or wires. There are no spark plug wires in Quad-4 engines. On 3.4L engines, you must first remove the upper intake manifold to get to the right side (rear) spark plugs or plug wires. To reach the right side (rear) spark plugs or plug wires on 1996 and later 3800 engines, one must remove the acoustic engine cover first. Check the spark plug wires at recommended intervals as well as whenever new spark plugs are installed in an engine. Inspect one wire at a time so that they cannot be mixed up because it is important for good running of an engine. Remove the wire from the spark plug itself, by pulling on its rubber boot after grabbing and twisting it a little bit. Do not pull on the wire itself, only on the rubber boot itself. Inside of this boot there will be corrosion that looks like white crusty powder. Pushing both wire and boot back onto end of sparkplug; it should fit tightly. If not remove wire and carefully crimping metal connector inside boot with pliers until it fits snugly onto end of sparkplug should do it,. Use a clean rag to wipe all along length of wire removing any accumulated dirt grease, Check for burns, cracks, and other damage after cleaning wire, Never bend or pull excessively on a wire-conductor inside can break, Now, disconnect coil from coil pack; once again, pull only on rubber boot. Make sure you have checked for corrosion same way as described above. Put new wire on coil, One should then check remaining wires one at a time making sure when checking complete they are still properly attached to both ignition coil and sparking plug. Therefore, if new spark plug wires are needed, a set should be bought for the specific model of your engine. For these wire sets that come in pre-cut form with rubber boots already fixed, purchase for your engine model. To prevent mix-ups in the firing order, remove and replace one wire at a time.

Spark plug wires should be regularly inspected to ensure their proper functioning.

The spark plug cables should be visually checked for burns, cuts, or breaks in the insulation. The boots and nipples on the distributor cap or coil should also be checked.

For V6 engines, disconnect the wire from the ignition coil assembly in a similar manner, inspect for corrosion, and ensure a secure fit before reattaching it.
