Take off the alternator belt, tensor, fan and cap of timing belt, review the mark of cranshaft pulley must be in 10grades BTC The grades are on the cap, then review the mark valves pulley and put the timing belt (Note disconect the battery in order to delete the failure) placement again all the parts and thats all.
IF YOUR ENGINE IS A 3.0 V6 3VZ-E YOU REMOVE AIR INTAKE PIENUM,AND ALL SURROUNDING COMPONENTS REMOVE THE FUEL RAIL THE INJECTORS ATTACHED ,REMOVE INTAKE MANIFOLD,THEN YOUR EXHAUST CROSSOVER PIPE,EXHAUST MANIFOLDS REMOVE ALL BELT'S AND PULLEYS ,TIMING COVER .....BEFORE REMOVING YOUR CRANSHAFT PULLEY ,ALIGNMENT YOUR TIMING MARKS ,ON CAMSHAFT TIMING PULLEY LT,RT ,CRANKSHAFT TIMING PULLEY,THEN REMOVE TIMING BELT TENSIONER ,REMOVE ALL CAM SHAFTPULLEY'S AND CRANKSFT . REMOVE DISTRIBUTOR.REMOVE HEADCOVERS,CAMSHAFT,THEN YOU COULD GET TO THE HEAD BOLTS.
Rigoe the points for the timing belt are usually located on the sprokets in conection with marks or dots on the engine block some where around the sprockets that hold the timing belt. Remenber to bring the piston number one to TDC (top dead center), this means you have to locate the piston number one, take the spark plug out and turn the cranshaft (the one with the pulley) by hand until the piston is all the way up. On the distributor the rotor should point to the spark-plug wire number one (you can make a mark outside of the distributor cap where the number one spark-plug wire is pointing so when you take the cap off you can see if the rotor is pointing the same direction). With the timing belt cover off you are going to be able to aling all this points at the exact locacation all together. So we have: Piston number one at TDC, The rotor(enside the distributor cap) pointing to the number one spark-plug wire, and the mark of the sprockets pointing the marks of the engine block( litle dot or dash). If you get all this right you are have done a good job and ready to make a trip you can get all this just by turning the cranshaft by hand with a rachet and a big socket. God bless you.
I have a 2001 Lanos and I've replaced my belt twice (after breaking the first one at speed and having to replace the engine). The two cam gears have timing marks that should point towards each other. If you hold a ruler up with the edge of it passing through the center of the cam shaft bolts, the timing marks on each cam should be lined up on with the edge of the ruler and pointing towards each other. The crankshaft gear (not the big pulley) has a small triangle timing mark on it that should point almost straight down. There is a V cut into the oil pan that actually should line up with the cranshaft timing mark. BE VERY CAREFUL because if you rotate the crankshaft independently of the cams, you can tear up the valves very quickly.
You must have #1 on TDC and the camshafts on the timing mark to fit a new belt , I rekon yer valves are fouling the piston .
Ignore the mark on the pump pulley .
it was good to check how timing is before you removed old belt.
anyway first before you fited new one rotate the engine by hand look front crankshaft timing mark,
put piston number one should top dead center look cranshaft mark.when you done.
second step is to set up camshaft check timing mark on the camshaft follow the marks fisr cylinder.
