2010 Toyota Corolla • 4 cylinder FWD Automatic • 20,000 miles

How do I change the spark plugs on a 2010 Toyota Corolla with a 1.8 liter engine? I have tried several different spark plug wrenches but none of them seat on the spark plug.

Did you talk to the people at the autostore? Tell them you want to see a spark plug for your year--make--model and engine size, Then tell them you want a socket to fit it. It usually doesn't have to be a spark plug socket, the spark plug socket probably has more protection for the spark plug. I'll look around, see if I can find a size?

If I was looking at the right spark plug, 9/16 inch or 14.3mm, hex size.

Sometimes you have to clean out the plug-well before the socket will fit. Wear safety glasses, if you use compressed air.
