3' breaker is plenty, remove rubber plug on flywheel (top pas side of engine) insert large screw driver or pry bar, wedge flywheel and pop crank bolt free. Same method makes sure you get it tight when replacing. Locktite is not necessary if you get the bolt tight to begin with. Three marks to keep aligned , the crank is easy ,one cam is under tension and one is not. When installing the belt start at the crank keeping tight go around tensioner and drivers side cam , keeping tight continue around to other cam , here is where I will allow the cam to be off time (towards the fender) a small amount as it will roll towards the crank as you finaly get the belt to slip on , its not hard but its also not easy... be calm it will fit. Do not worry about the lines on the belt do not try to line them up. Once you have the belt on and all your timing marks are good then you pull the pin on your tensioner allowing it to move... now put your ballenser(pulley) on and slowly rotate the engine clockwise around two times until all three timing marks are aligned. I should mention that the passenger side cam has no real mark to align with just straight up with a case seam directly above it is all you get on that side. If after turning over the motor ANY of the timing marks are not dead on then you do it all over... (can be frustrating ) Don't get excited just take your time and you will get it right. Afterwards you will never be afraid to open up the front again because you will be an expert. Very important is getting the ballenser bolt good and tight or the pulley will come loose and do terrible things to your crankshaft and radiator. I should mention that if you have to repeat this instalation then you will have to compress your tensioner and re install the pin , do this in a vise and do it slowly little turns and it will easily compress and you can place the pin thru all three holes and then remove from vise , your ready to try again . DO NOT FORCE THE TENSIONER,
