How do you change spark plug wires in 1999 corolla?

Answer 1

You can go to the dealer or to an auto parts store to buy new spark plug wires. When you get them open the box and lay the plug wires side by side on the work bench,you will see that there are 4 wires and each one is slightly longer than the other. Now looking at the engine, you will see that there are 4 plug wires on the top of the cylinder head, starting with the plug wire on the far left, gently pull the plug boot ( do not pull on the wire ) free of the spark plug hole, then follow the wire to the plastic connector, this is round and cylindrical in shape,on the right side of the connector you will see a lever, push the lever in, and pull connector apart, then taking the longest new wire, push the connector together until it " clicks ", then press the spark plug boot down firmly until it is in place,compare the new one you just replaced to the other old 3 ones and see how far down it should be. Then continuing from the left to the right, replace the remaining spark plug wires. ( note ! ) Only remove 1 spark plug wire at a time.
