The firing order of almost all engines is stamped into the intake or head.

You don't have a timing belt, you have a timing chain..(that's for the other foreign automaker...that charge way to much at the lot..but are way too cheap to give you what you pay for.) you timing chain is located under you valve cover gasket, you would have to remove it in order to get at the chain.
the chain keeps the camshaft/valves in time with the crankshaft in order for combustion to take place
In order to replace a timing chain for a 2003 Chevy Cavalier, a person will need remove the oil pan, crankshaft pulley and hub, timing cover bolts, and timing cover. Then the timing cover gasket, timing cover and bolts, crankshaft pulley, and oil pan will need to be installed.

Typically, "timing cover and gasket" refers to timing chain (vice timing belt) equipped vehicles. Timing chains need oil from the engine for lubrication. To make this happen, there is an opening between the timing chain area and the valve camshaft area. The oil the flows into the timing chain area, then down into the oil pan. In order to keep the oil from spraying all over the rest of the engine (and having the engine break down from oil starvation), a metal 'timing cover' is installed over the timing chain and sprockets. Then, a 'gasket,' made of a soft, oil resistant material, goes between the timing chain cover and the engine block to prevent any leaks. The timing cover is bolted to the engine block and the bolts tightened to a specified torque.
Timing chains do have a finite lifespan. Depending on driving conditions and maintenance history - timing chains can last anywhere from less than 60,000 miles to more than 200,000 miles. Generally recommended to check the timing chain at close to 100,000 miles to make sure that everything is in order.
It's a load of a job,Remove radaitor, all hoses, pullys, belts,Valve covers, timing chain tensioner and guides. replace pump which is run off the timing chain. Make sure to line up the 3 marks on timing chain so you have correct timing. Reinstall tensioner and make sure it is recharged(all the way out) Turn engine by hand with a wrench to make sure chain is tight and timing is correct(Very important). Reassemble engine in reverse order. This would be a good time to replace the timing chain and tensioner if over 100,000 miles, good luck.
123456 That should have been marked on the intake manifold, towards the rear of the engine. The firing order is correct! However, it has a timing belt, not a chain. The water pump is driven by the timing belt, so replace that while your in there. And Make sure the crank and cams on on TDC before you put the belt on!
