Question about Cars & Trucks
Just finding top dead center and making sure the timing belt and gear are in the correct position.
TDC mark , line up mark on pulley on crank shaft with mark on timing cover housing. a mark on the cam shaft gear should line up with a mark on the head most times at 12 o'clock, If you can't find the marks rotate the camshaft till the valves on the rear cylinder just start to rock that will show where the marks are . the crank shaft may have to be moved slightly to turn the camshaft do this by hand as a valve may touch a piston

Think you have to put a flat bar across the back of the cam shafts same as the old ZETEC ford motors. Failing that are the vernier pullies marked with eithr O T or do they have a - or a . that line up with a position on the end of the cylinder head.

First pull the timing belt tensioner then slip the belt off the cam gears. You then need to find TDC (Top dead center). 3 ways to find TDC 1) There are marks on the crank pulley align them for TDC. 2) Remove timing cover and use crank gear mark seen in link below 3) Put the dip stick in cylinder 1 and turn engine until dip stick stops going up. After finding TDC align cam gear marks seen in link below. Now make sure both cam and crank stay in position and slip timing belt back on (you can move the cam gear to get the belt on but make sure the marks are aligned after the belt is on). Last tighten the belt tensioner, I usually use my finger or an extension to get some more tension on the belt. You might have to remove engine mount bracket makes life much easier as the front cover section is TIGHT !!!. Turn engine a few times to make sure you have compression and engine turns without getting stuck. See link below good luck.
