Where is the oil pump located in the pan or in with the timming belt

It's my understanding that the Avalon and Camry for said year are the same in respect to
the oil pump.I was able to come up with a video to show you how all the stuff has to be removed
from the front of the engine in order to get to the oil pump for replacement.This took some time
to find,but I do not mind.My friend,you've a lot of work ahead of you.I've been thru it before,and
won't do it again.Best of luck to you in your endeaver.

Now the oil pump proceedure in print:
Instructions
Remove Oil Pump
1
Drive your Toyota Camry up onto ramps or lifts so you have room to work as you pull out the oil pump.
You could also use a jack, but make sure you brace the front wheels so they don't roll. In addition,
set the emergency break firmly into position so the car doesn't roll.
2
Drain the oil out of your engine and disconnect the negative battery cable. Remove the fender apron
seal and the undercover, the front exhaust pipe, and the front exhaust pipe bracket from the No. 1
oil pan.
3
Remove the following components in order: the alternator drive belt, the air conditioner compressor,
the power steering pump drive belt and the adjusting strut, the timing belt along with the belt
pulleys, the rear timing belt cover, the air conditioning compressor housing bracket, the No. 2 oil
pan and oil strainer, as well as the No. 1 oil pan and baffle plate.
4
Disconnect the crankshaft position sensor and remove all nine of the oil pump bolts. Remember where
each bolt was located.
5
Take out the oil pump body by reaching in and grasping between the oil pump and main bearing cap.
Remove the O-ring from the cylinder block then remove the plug, gasket, spring and relief valve
from the oil pump body.
6
Finish by taking out all nine screws, the pump body cover and the driven rotors. Clean all
components to remove contaminants.
Install the Oil Pump
7
Install the new oil pump by slipping it into the same spot where the old one was. Reconnect
the following: the driven rotors, the drive pump body cover, all nine screws, the oil pump
relief valve, the spring, the gasket and the plug to the oil pump body.
8
Insert a new O-ring onto the cylinder block and add liquid sealant to the oil pump and the
engine block. Put the oil pump back on the engine block.
9
Add and tighten the bolts over several passes, keeping the torque even. The 10 mm head should
be 69 in-lb. and the 12 mm head should be 14 ft-lb.
10
Reconnect the crankshaft position sensor, torquing the bolt to 69 in-lb. Insert the No. 1 oil
pan and oil strainer and the No. 2 oil pan.
11
Reinstall the air conditioner compressor housing bracket, tightening the bolts to 18 ft-lb.
Add the rear timing belt cover, tightening those bolts to 74 in-lb. Insert the timing belt
pulleys, the timing belt and the adjusting strut and power steering drive belt, tightening those
bolts and the nut to 32 ft-lb.
12
Install the air conditioning compressor, the alternator drive belt and the front exhaust pipe
bracket to the No. 1 oil pan, torquing the bolts to 15 ft-lb. Add the front exhaust pipe, the
undercover, and the right fender apron seal.
13
Connect the negative battery cable and fill the engine with fresh oil. Start your Toyota Camry
and look for leaks in your working area.

it is common for the oil pump to go bad after changing the timing belt.

the pump is located in the oil pan, and nothing drives it, it works as a sucking action....
