Timing belt cover will not come off, due to alt. brack. bolt ...
I got it striped down to the alternater out and cruise control i beleive also removed and out of way. I can not figure out how to get the timing belt cover off with that alternator and tentioner bracket stuck. I got one bolt to go i think before i can take the alterator bracket off and thats under where the alternator was before i removed it. I cant get that bolt out, or the tentioner off. PLEASE HELP!!!!

Alternator, Replace Vehicle: 2007 Nissan Versa SL 1.8 L4 GAS Remove front passenger wheel. To the right of the shock/spring housing you'll see two plastic pins. This holds the splash shield in place, remove them & open the splash shield. Using a 14mm wrench, put it at about 4 o'clock on the spring tensioner arm & pull down. This relives tension on the belt, slide the belt off the wheel that's to the right of tensioner. Go under the hood, using a 10mm socket disconnect neg side of terminal on the battery. These other steps are to allow room to work & space to remove alternator. Next remove the 2 bolts on the nissan plastic engine cover housing & the engine cover housing BRACKET that's located at the front LEFT corner of the valve cover. Unbolt ground strap that's located on the cars frame right behind the left headlight, in addition left to ground bolt, unbolt the bracket that supports the a/c line. Remove radiator reservoir tank, disconnect belt & wires from the alt. The two 13mm bolts on the alt use a wrench. When loosen then use a 1/4 ratchet with a 13mm socket. Slide bolts out as FAR as possible. Now you should be able to wiggle out alt & bolts as one piece. I had to use a long screw driver/bar to dislodge alt. Install in reverse order. Total time took me about an hour.

TDC stands for "Top Dead Center". This is when the piston is at the very top of its travel and there is no place for it to go but down. If you are trying to get a timing belt in time, all you have to do is align the timing marks on the crankshaft pulley with the TDC mark on the timing belt cover. If you are replacing a timing belt, this should be done AFTER removing the crankshaft pulley bolt and BEFORE removing the pulley and timing cover, otherwise you will have to put the timing cover and crankshaft pulley back on to do this. To get your "stroke" that you are asking about, you have to align the camshaft pulleys with the corresponding marks on the No. 3 timing cover. (See pictures)
Disconnect the negative battery terminal. Using a ½-inch-drive ratchet and the 19 mm socket, turn the center bolt on the crankshaft so that number-one cylinder piston is at top dead center (TDC). You will know you ware at TDC when the mark on the crank is in alignment with the arrow on the timing cover.
Disconnect the cruise control connector and remove the cruise control actuator. Loosen the upper mounting bolt with the 14 mm socket. Use a 12 mm socket to loosen the lower nut then use a 10 mm socket to loosen the adjuster from the power steering pump and remove the belt.
Loosen the upper air conditioner mounting bolt using the 14 mm socket. Use the 12 mm socket to loosen the lower nut and adjusting bolt on the alternator and remove the alternator/AC belt. Remove the valve cover using a 10 mm socket.
Place the jack behind the left front wheel where the arrow is located indicating the jack location, and raise the vehicle. Put the jack stand under the subframe behind the jack, then lower the jack. Remove the left front wheel for easy access to the crank pulley. Using a block of wood atop the jack, place the jack under the oil pan and lift with slight pressure to hold the engine in place. Remove the side engine mount using a 17 mm deep socket.
Take off the dipstick, pipe tube and upper timing cover using a 10 mm socket. Then remove the timing belt adjuster rubber seal without loosening the adjuster nut. Take off the crankshaft pulley bolt. Use the chain wrench to hold the the crankshaft pulley while turning the crankshaft pulley bolt with a 19 mm socket. Use the 10 mm wrench and 10 mm socket to remove the bolts on the lower cover. Remove the lower cover and mark the location of the cam, crank and balancer shaft with Liquid Paper. Remove the balancer shaft belt and timing belt.
Install the timing belt and the balancer shaft belt in the reverse order of removing them. During Installation of the crank pulley, coat the threads of the crank pulley bolt with engine oil and tighten it to 159 foot-pounds. Finally, adjust the tension of the power steering and alternator belts as well.
Remove the A/C compressor drive belt tensioner.

Crankshaft sprocket and oil pump cover alignment marks 2.5L DOHC
Align the timing mark on the crankshaft sprocket with the mark on the oil pump cover.
Timing belt alignment marks DOHC
Align the single timing mark on the right exhaust camshaft sprocket with the notch on the timing belt cover.
When the single timing mark on the right exhaust camshaft sprocket is aligned with the notch on the timing belt cover, ensure that the double lines on the intake camshaft and exhaust camshaft sprockets are aligned.
Align the single timing mark on the left exhaust camshaft sprocket with the notch on the timing belt cover by turning the sprocket counter clockwise (viewed from front of engine).
Ensure that the double lines on the intake camshaft and exhaust camshaft sprockets are aligned when the single timing mark on the left exhaust camshaft sprocket is aligned with the notch on the timing belt cover.
The camshafts can be rotated independently causing the valves heads to contact each other resulting in bent valve stems.
When the timing belt is removed the camshafts will turn to the lowest cam lobe position by the force of the valve springs. Before installing the timing belt the 4 camshafts are in the lowest lift position (valves closed).
When the camshafts are rotated to install the timing belts, # 2 intake and # 4 exhaust cam lobes of the left camshafts are held to push their corresponding valves down. In this position, these valves are held in the open position. Right camshafts are held so their cam lobes do not push the valves down.
The left camshafts must be rotated from the lowest lobe position to the position where the timing belt can be installed at the smallest possible angle in order to prevent intake and exhaust valve contact.
Camshaft sprockets rotation
Do not turn the camshafts in the direction shown in the illustration because the valves will open at the same time and contact each other.
CAUTION If the timing belt alignment is off the mark buy more than 3 teeth, the valves and pistons may have contact.
Timing belt alignment marks DOHC
Align the timing marks on the belt with the marks on the sprockets in the numerical order shown in the illustration.
