jun Posted November 15, 2005 Share Posted November 15, 2005 HELP! Can anyone give me step-by-step instructions for replacing the spark plugs (the 3 close to the firewall) on a 94 Camry XLE V6 1MZFE engine? What exactly needs to be removed and how, especially the air intake side? Thank you very much. Quote Link to comment Share on other sites More sharing options...
stevelaw Posted November 21, 2005 Share Posted November 21, 2005 Here are the general instructions: On the 2S-ELC, 3S-FE and 1992 5S-FE engines, the spark plugs require replacement at 30,000 miles (48,000 km). On all other engines the spark plugs are platinum and require replacement every 60,000 miles (96,000 km). When you're removing spark plugs, work on one at a time. Don't start by removing the plug wires all at once, because, unless you number them, they may become mixed up. Take a minute before you begin and number the wires with tape. Disconnect the negative battery cable. If the vehicle has been run recently, allow the engine to thoroughly cool. Remove the cap nuts and valve bank cover(s). On 1MZ-FE engines, disconnect the ignition coil wiring from the right and left cylinder heads. Remove the ignition coils from the cylinder heads. Arrange the coils in order on a table. Carefully twist the spark plug wire boot to loosen it, then pull upward and remove the boot from the plug. Be sure to pull on the boot and not on the wire. If compressed air is not available, use a rag or a brush to clean the area. Remove the spark plugs when the engine is cold, if possible, to prevent damage to the threads. If removal of the plugs is difficult, apply a few drops of penetrating oil or silicone spray to the area around the base of the plug, and allow it a few minutes to work. Using a spark plug socket that is equipped with a rubber insert to properly hold the plug, turn the spark plug counterclockwise to loosen and remove the spark plug from the bore. Yours may be 5/8. Inspect the spark plug boot for tears or damage. If a damaged boot is found, the spark plug wire must be replaced. Quote Link to comment Share on other sites More sharing options...
jun Posted November 22, 2005 Author Share Posted November 22, 2005 thank you very much. I have another problem now with P0773. Can you also help on this? Quote Link to comment Share on other sites More sharing options...
stevelaw Posted November 30, 2005 Share Posted November 30, 2005 Seems like a few folks out there are having auto tranny solenoid problems. Are you no longer under warranty? That's powertrain. Quote Link to comment Share on other sites More sharing options...
