Hope this helps (remember to rating this answer).

Install the cylinder head bolts. Starting at top center, tighten all cylinder head bolts in sequence as shown in illustration, using the Cylinder Head Bolt Wrench (09221 - 32001) or equivalent. Repeat the procedure, re-tightening all cylinder head bolt to the specified torque. (torque spec is Cold Engine 105-115 Nm (76-83 ft lb) )
. Install the timing belt tensioner pulley.
. Install the timing belt on the camshaft sprocket, making sure that the tension side is tightened by turning the camshaft sprocket in reverse, all timing marks are in alignment.
. Adjust the timing according to "Timing Belt"
. Install the rocker cover and tighten the bolts to the specified torque. Tightening torque: Rocker cover belt:

2.5-3.5 Nm (25-35 kg.cm, 2-3 ft. lbs.)

. Install the timing belt cover.
Install the new intake manifold gasket and the intake manifold. Tighten the nuts and bolts to the specified torque.
Install the new exhaust manifold gasket and the exhaust manifold. Tighten the exhaust manifold attaching nuts to the specified torque.
. Install the surge tank and tighten the nuts bolts to the specified torque.

Front Pipe REMOVAL & INSTALLATION Pipe Without Catalytic Converter

1. Before removing any component of the exhaust system, always squirt a liquid rust dissolving agent onto the fasteners for ease of removal..
2. Raise and support the front of the vehicle on jackstands.
3. Remove the exhaust pipe-to-manifold nuts.
4. Support the catalytic converter, then disconnect the pipe from the converter. Remove the pipe.
5. Remove the exhaust gaskets. To install:
   
6. Be sure to use all new gaskets when required. Assemble the system, check the clearance and tighten the bolts to about 15-30 ft. lbs. (20-41 Nm). Fig. 1: Front exhaust pipe connection common on vehicles with the catalytic converter not included
   
   
7. All clamps should be tightened to about 18-25 ft. lbs. (24-34 Nm). Do overtighten the clamps. If pipes become dented they can leak.

Pipe With Catalytic Converter

1. Before removing any component of the exhaust system, always squirt a liquid rust dissolving agent onto the fasteners for ease of removal.
2. Raise and support the vehicle.
3. On some vehicles you will need to remove the brace from the transaxle.
4. Remove the exhaust pipe nuts from the manifold.
5. Support the catalytic converter pipe bolts from the rear of the converter.
6. Lower the catalytic converter/front pipe assembly from the vehicle. To install:
   
7. Be sure to use all new gaskets when required.
8. Attach the new catalytic converter/front pipe assembly to the vehicle. Tighten the pipe to manifold nuts to 20-40 ft. lbs. (27-55 Nm).
9. Attach the bolts at the rear of the catalytic converter/front pipe. Tighten them to 30-35 ft. lbs. (41-47 Nm).
10. Connect the brace at the transaxle if removed.
11. Lower the vehicle.

Water pump is driven by timing chain idler and is mounted on the rear of the timing chain housing. Disconnect the neg. battery cable. Drain cooling system. Disconnect oxygen sensor connector.
Remove upper exhaust manifould heat sheild. Remove exhaust manifold brace. Remove lower exhaust manifold heat sheild. Loosen manifold to exhaust manifold spring loaded nuts. Remove radiator outlet pipe to water pump coverbolts. Disconnect exhaust pipe from manifold.
Pull down on the exhaust pipe to disconnect it from exhaust manifold bolts. Disconnect outlet pipe from oil pan and transaxle. If equipped with manual tranaxle, remove exhaust maifold brace. Leave lower radiator hose attached and pull down on radiator out look pipe to disengauge from water pump. Leave outlet pipe hanging.
Lower vehicle. Remove exhaustmanifold to cylinder head nuts. Remove exhaust manifold to cylinder head nuts. Remove manifould. Remove timing chain front cover. Remove timing chain tensioner. Remove bolts bolts securing water pump cover to cylinder block. Remove water pump to timing chain housing nuts. Remove water pump attaching nuts. Remove water pump and cover assembly. Separate componets as necessary.
WHEN INSTALLING WATER PUMP MAKE SURE YOU FOLLOW THE TIGHTENING SEQUENCES THAT AFFECT SEALING. My frist one I messed up and broke the pump so becarful.
Installation
If cover was separated from body during removal, join this componets with a new gasket and hand tighten bolts. Apply bearing grease to splines of water pump drive. Set body and assemble into position.
Install and hand tighten bolts securing cover to cylinder block. Install and hand tighten bolts securing cover to cylinder block. Installand hand tighten nuts securing body to timing chain housing. Lubracate outlet pipe "O" ring with antifreeze. (I use RTV) Connect outlet pipe. Install and hand tighten bolts. Tighten bolts and nuts to specification in the following sequence. I'll ad the torque spec. at the end but this is where if you tighten out of order something will break.
pump assembly to timing chain housing nuts.
pump cover to pump body bolts
pump cover to cylinder block bolts (Bottom Bolt First)
outlet pipe to cover bolts
To complete installation reverse removel procedure.
Torque specs are 19 in. or 26mm all except water pump cover bolts which are 124 in or 14Nm
I never torque the bolts just make sure there done in the right order.

According to the service literature I read, the 2003 Montero Sport with the 3.0 or 3.5 L engine does not have O2 sensors listed even in the maintenance schedule. The 2.4 L engine has it on the exhaust manifold though.

However, the following lists the par, though for before or after the catalytic converter:

---
I think that $250 to $300 is reasonable if the Oxygen sensors are stuck in there with rust and the threads are preserved by the technician. Oxygen Sensor replacement can be tricky.

Good luck on this repair.

2.4 enigine is the harder of the 3 enignes. it will need a timing chain to be removed and a coolant tube in the back of the engine to be removed. this job on the book calls for almost 7 hours.

if its 3.3 or 3100 its alot easier.

3100 is just 4 10mm pulley bolts and 5 or 6 small 8mm water pump bolts.

3.3 is alittle more work, but same concept as 3100 engine. more owkr only cause its in a tighter area.

good luck,
michael
