Easiest way to replace freeze plug!
Ok so you have a freeze plug issue (provided its the first freeze plug behind header)
remove serpentine belt, power steering pump, an bracket. It will be alot easier to get to instead of removing manifold and headers. Using a prybar or LARGE screwdriver, hit the freeze plug and knock it loose. Take a pair of pliers or channel locks and remove plug. Discard and replace the plug. Either a regular plug or the expandable plug will work. Depending on the plug it will either be a 1" or 2" plug. Put all the brackets and powersteering pump back on and get back on the road. It took a total of about 15 minutes to do the job provided you have all the parts to do the job with you. It is a pretty simple job even a beginner can do.
