Tip & How-To about Toyota Tacoma
Spark plugs on a car should be replaced every 2 years or 24,000 miles. To remove the plugs you need a ratchet and either a 13/16 or 5/8 inch spark plug socket, depending on your car's spark plug size. A universal-joint drive-handle attachment and extension attachments can help you reach awkwardly placed plugs. Fit the socket firmly over the hex section of a plug and with the ratchet set to unlock, apply pressure counter clockwise. Hit the handle with the heel of your hand to unseat a stubborn plug. If it continues to stick, use penetrating oil. If it takes effort from start to finish to unscrew a plug, clean the threads of the hole with a thread chaser before installing a new plug. Replace plugs with the brand and model number recommended by manufacturer or with a manufacturer's equivalent. If your engine has an aluminum head, apply a film of anti seize compound (available in tubes from auto parts stores) to each new spark plug's threads. Use a spark plug gauge to adjust the gap between electrodes of each new plug. (Refer to your owner's manual or gap specification on the decal under your car's hood.) The gauge should fit snugly in the gap. To adjust the gap, use the gauge's bracket to bend the L shaped side electrode. Recheck with the spark plug gap gauge. Thread each plug into it's hole by hand until it seats. If the plug has a gasket,m use the ratchet to tighten it quarter to a half turn more. If there is no gasket, only a sixteenth of a turn should be needed. Lightly apply silicon dielectric grease to the inside of the cable terminals: then push each terminal onto the nipple of its spark plug.
