Where are the spark plugs and wires at on my 05 2.2 sunfire

Hello: If it is a EcoTec engine it does not have plug wires, On the top of the valve cover there is a plate, on the drivers side there is a electrical connector. Remove it. Remove the cover (6 bolts or may be 8) pull up on the cover, there are boots that connect to the spark plugs. The spark plugs are in the cylinder head under the cover.

How To Change The Spark Plugs On A 2002-2005 Kia Sedona 3.5 Liter

You'll need to remove the oil cap and the 6 bolts holding on the engine cover. The front 3 spark plugs are pretty easy to replace. You'll need to unplug the spark plug wire from the coil and disconnect the electrical connector. Unbolt the 2 10mm bolts holding the coil to the valve cover. Twist the coil and boot back and forth and pull it out of the cylinder head. The spark plug is down in the head, you'll need at least a 6 inch extension with a 5/8" spark plug socket, a telescopic magnet will help get the spark plug out of the head. The back 3 spark plugs involve removing the upper intake and throttle body, unbolt the bracket to the throttle body, and the bracket bolted to the upper intake manifold. on the back side of the engine. Remove the tubing from the throttle body to the air cleaner box. Unbolt anything else bolted to the upper intake. Unplug electrical connectors to the throttle body and any other electrical connectors on the upper intake and remove the upper intake bolts. And move the upper intake out of the way, there are only spark plug wires on the back 3 plugs. Twist and turn each boot to aid in removing the boot from the plug. I would get a new upper intake gasket and consider replacing the wires at this time also. There are actually only 3 spark plug wires, so for what is involved to get to them, I would replace them. I have found alot of the wires will arc to the upper intake manifold.

Direction on how to replace coil pack 1988 pontiac grandam

The coil pack rests on the back of the engine, under the intake manifold. Make sure the engine is cool. Follow the plug wires to their ends and you'll see the coil pack. Mark the wires with tape and number them 1-4 so you know the order the plug wires are in. You'll need to remove the entire ignition pack to replace the coils. Three 10 mm bolts hold it in place. Remove the marked plug wires from the pack, unplug the two wire connectors. I worked the pack out from underneath the care. There is a crank sensor on the back of the unit - be careful not to break it as you remove the unit. Take the pack to a table and remove the 4 small nuts that hold the coils in place. Clean all the connectors and apply some dielectric grease to all the electrical connectors. Add some grease to the o ring on the crank sensor and clean all the other parts. The 4 bolts that hold the coils on can only be replaced by pulling the entire unit. Install the new coil spade connectors into the base, being careful to align them properly. Snug down the 4 small nuts that hold the coils on while holding the bolts that secure them with your fingers until the get tight - be careful that the bolds fit into the recesses that hold them squarely. Replace the unit in the car as you removed it with the three 10 mm bolts. Be sure to follow the numbers on your plug wires as you replace them. Reconnect the two wire connectors after cleaning the contacts. Replace the ground to the upper right bolt of the pack. Now would be a good time to replace the plugs and plug wires as well! Took me about 2.5 hours.

The heater in my 2000 wrangler does not work. There is a connector with black/white, yellow and orange wires hanging down under the blower motor under the glove compatrment. Where does this connector...

You will see a round plastic blower motor housing underneath the passenger dash approximately 6-7 inches round, plug the connector back into it and you should be good to go.Let me know if it works for you or if you need further assistance

How do you change the back spark plugs

Take out the coils - its worth it! If you don't you have to get under it and get at them from underneath. The coil packs are all mounted on a single piece of aluminum that is secured by 4 bolts, 2 front and 2 back. do wires while you're at it, they are made to stay on no matter what, and pulling them off can easily damage them. Make sure they don't hang down on anything that gets hot like exhaust manifolds. This might not be very easy with California emissions - theres a lot of extra tubing and wires to deal with.

I tried from underneath and accidentally cracked a plug because I had to do everything blind. Of course it was on the back row.

How do I replace the plug wires on a 1996 Chev. Cavalier? It looks difficult

Just did it on my 96 Cavalier last weekend. Get a good set from the parts store. Then if your plug wires you just bought aren't labeled 1,2,3,4 (cylinder designation) MARK THEM WITH A SHARPIE at least on the ends and on the cord once or twice. The factory cords have this marking all down the length of the wire. I found the best way to get at the coil is underneath the car where the tailpipe comes through underneath from the engine compartment. You'll have to jack the car up on both sides if your a large fella, use jackstands for safety! Now work from the bottom on the coil, you can reach up through the hole where the exhaust comes from the engine compartment heading back. The coil is just in view laying underneath and peering up. Trace the wires if you can't find it at first. I laid the new wires over the top of the block and dangled the coil-ends down behind the block so the new cords would be there ready to plug in when working from above and so they would be in the right order. Also go ahead and undo all the plastic snaps and take off the plastic covering that holds the old wires together. Unplug from the sparkplugs and feed the old wires down through the exhaust header where they come through. Now from underneath you can pull each wire off the coil one-by-one paying attention to the number on the wire, just plug the new wire in the place of the old one. I went ahead and pulled the old wires out through the bottom and just threw them out to the side so they were no longer in the way. After you make the wire-by-wire transition on the coil, head back under the hood and hopefully at this point you will change the plugs as well. Hook them up 1-4, with 1 being the closest to where the alternator etc. is. It IS a TIGHT FIT underneath, but I couldn't get my arm between the block and the firewall at all from above to reach, much less see, much easier from underneath!
