Does anyone have detailed instructions on how to replace a timing belt for a 1996 camry v6 3.0?
As every car is a little bit different, it is impossible to detail the requirements for every car. However, here is a general guide as to what you can expect to have to do when replacing a timing belt. I highly recommend buying the appropriate Hayne's Manual for you car at an auto supply store. It's a great reference that includes step by step instructions and helpful pictures.
Wait overnight for the engine to cool off. It's not worth it to risk burning yourself on the engine, which stays hot for a long time!
Disconnect the battery and chock the wheels so that the car cannot roll. Remove all obstructions to the timing belt cover: This can take a while, as there are usually quite a few things in the way. Here's a list of a few common pieces you'll have to remove: Remove the air intake assembly.
Loosen the pulley that powers the water pump, if necessary. Some cars require your to remove other equipment such as the power steering pump. If so, remove the belt from the pulley, and unbolt the pump. Move it back out of the way. Remove any other accessories that interfere with access to the timing belt. Use a large wrench on the crankshaft pulley to align the mark on the crankshaft pulley with the 0 on the timing scale molded into the engine block. Remove the timing belt cover bolts and pull the cover off. Check the tensioner bearings. Replace them if they are loose or noisy. Check the camshaft and crankshaft seals. If they leak, it could cause premature failure of the new timing belt. Replace them if necessary. Make sure that all timing marks are properly aligned, then loosen the timing belt tensioner and remove the timing belt. Do not allow either the camshaft or crankshaft to move while the belt is off. Put the new belt in place. Adjust the tension, if necessary. Make sure that it sits well over the teeth of the timing sprockets. Don't over-tighten. Apply a new gasket to the timing belt cover and replace it. Reinstall all of the accessory pumps that you took off earlier, including the water pump. Many mechanics recommend replacing the water pump while you have it off. It's up to you. Check that all timing marks are still properly aligned. Reinstall the air intake assembly. Reconnect the battery. Start the engine and listen carefully to how it runs. You shouldn't hear any loud knocks if the timing is still correct.

PS. I think you should better go to a mechanic. You'll be charged something like a 100$. If you are not 100% confident in what you're doing, you can damage the car and then it will only get worse. I advise you to go to a mechanic (a guy with his own garage, don't go to walmart or something of the sort, they will charge you 10x more) and ask him how much for the labor and parts. Good luck !
