Tip & How-To about Ford Escort

Removal and installing spark plugs properly.

When I went into the local auto parts store, I asked the clerk about a specific spark plug. The clerk gave me the info, and then continued to tell me how the owner of the pick up truck in the parking lot had just bought a set of eight plugs and then when he removed the plugs from the engine, all eight of the spark plug access threads in the engine were stripped.
PROBLEM: the engine was hot when the owner removed the plugs.
SOLUTION: Always wait several hours (depending upon the outside air temperature) BEFORE removing spark plugs. ALSO, there is a gel available for coating the spark plug threads before installing them in the engine specifically for preventing spark plugs from freezing or adhering to the threads in the cylinder heads. Since spark plugs last so much longer now than they did in the past, they may remain in the engine as long as 50,000 miles. This gel is one method, in addition to cooling the engine from 5 to 8 hours to prevent stripping the threads in the cylinder heads.

How do you change spark plugs?

Hi my name is Tom and I can help you.

There is information that you must get when you pick up the spark plugs at the store. Ask the auto parts clerk what the plug gab is for your car. He will be happy to give you the info. If not go to a different store. You might ask him for a feeler gage. This tool is used to show the gap on the plugs.

Come home and open the engine department of the car. Take the wire off any spark plug using a spark plug wrench. Check the gap using the feeler gage.
Replace the wire onto the new plug. Repeat with the remaining plugs and wires

I trust that this is enough info for you to change the plugs. If not, I am more than willing to help you further.
