2005 Ford F-150 Question: spark plugs
I need to change spark plugs on my 5.4L V8 3 valve - Visitor
While normally a spark plug replacement is an easy process, you can open a can of worms with this job. This is something that you want to leave for a Ford specialty shop or to the dealership. The spark plugs are commonly breaking into the cylinder head and it's very difficult to remove them. Ford had to develop special removal tools to have the job done without removing the cylinder heads. Just do a search on Google. I have one suggestion, a week or two before you take your truck to get the plugs replaced buy 2 cans of BG 44K cleaner and add them to a full tank of Shell premium fuel. It will help to remove carbon deposit from the combustion chamber and makes the plug removal a lot easier. It will makes a big difference. Zee - ZeeTech
