Just need to know were the water pump on montero sport 1998 3.0 Ls engine????


It's under the timing cover on the front of the engine. I have pasted autozone.com instructions to replace the water pump below.


3.0L & 3.5L Engines

  1. Before servicing the vehicle, refer to the Precautions section.
  2. If necessary, properly release the fuel pressure.
  3. Drain the cooling system.
  4. Remove or disconnect the following:

    Negative battery cable
CAUTION Wait at least 90 seconds after the negative battery cable is disconnected to prevent possible deployment of the air bag.

Upper radiator shroud Accessory belts Air conditioning compressor tensioner pulley, if equipped Cooling fan and clutch assembly and the water pump pulley Thermostat and housing on 3.0L, 3.5L engines Water outlet, gasket and houses Radiator hoses from the water pump Crankshaft pulley(s) Timing belt covers. If the same timing belt will be reused, mark the direction of the timing belt's rotation, for installation in the same direction. Be sure the engine is positioned so the No. 1 cylinder is at the TDC of its compression stroke and the sprockets timing marks are aligned with the engine's timing mark indicators. Timing belt Water pump bolts are different lengths, note their positions before removing. Water pump from the block Water pipe connection and O-ring

To install:
  1. Clean and dry the mating surfaces of the block and water pump
  2. Install or connect the following:

    New O-ring on the water pipe connection, wet the new O-ring with water to aid in installation Water pump, with a new gasket, Torque the bolts to 17 ft. lbs. (23 Nm) on 3.0L and 3.5L engines Alternator bracket bolt to 17 ft. lbs. (23 Nm) Timing belt(s) and covers Crankshaft pulley(s) Thermostat and housing on 3.0L, 3.5L engines. Torque the bolts to 12-14 ft. lbs. (17-20 Nm). Radiator hose to the water pump Water outlet, new gasket and houses. Torque the bolts to 12-14 ft. lbs. (17-20 Nm). Water pump pulley Cooling fan and clutch assembly Air conditioning compressor tensioner pulley, if equipped Accessory belts Upper radiator shroud Thermostat and housing on 3.0L, 3.5L engines Negative battery cable
  3. Refill the radiator with coolant. This cooling system has a self-bleeding thermostat, so system bleeding is not required.
  4. Run the vehicle until the thermostat opens and fill the overflow tank. Check for leaks.
  5. Once the vehicle has cooled, recheck the coolant level.

Wont hold water. big hose on the bottom of the radiator attaches 2 the engine and it leaks right out of the engine underneath that hose...


Well, if that Radiator hose is not leaking, then the Water pump seals have gone bad. More than likely you need a new water pump.

Vehicles w/ Timing Belt Driven Water Pumps Should Always Have The Water Pump Replaced When The Timing Belt Is Replaced.

If you do not, then the Timing Belt will fail, turning a low cost repair into thousands because of valve train damages. . .

For the Timing Belt & Water Pump KIT - its around $258 through NAPA

I need to know the procedure to replace a water pump on a 2002 Mitsubishi Galant. Thanks


3.0L & 3.5L Engines9093fc4.jpg

Fig. Water pump and related components-3.0L DOHC shown (click for zoom).

  1. Disconnect the negative battery cable.
  2. Drain the cooling system.
CAUTION Never open, service or drain the radiator or cooling system when hot; serious burns can occur from the steam and hot coolant. Also, when draining engine coolant, keep in mind that cats and dogs are attracted to ethylene glycol antifreeze and could drink any that is left in an uncovered container or in puddles on the ground. This will prove fatal in sufficient quantities. Always drain coolant into a sealable container. Coolant should be reused unless it is contaminated or is several years old.
  1. Remove the engine undercover.
  2. Disconnect the clamp bolt from the power steering hose.
  3. Support the engine with the appropriate equipment and remove the engine mount bracket.
  4. Remove the timing belt. Refer to the timing belt procedure in this section.
  5. Disconnect the coolant hoses from the pump, if equipped.
  6. Remove the alternator brace.
NOTE The water pump bolts are different in size. Note their locations for installation.
  1. Remove the water pump, gasket and O-ring where the water inlet pipe joins the pump.
To install:
  1. Thoroughly clean both gasket surfaces of the water pump and block.
  2. Install a new O-ring into the groove on the front end of the water inlet pipe. Do not apply oils or grease to the O-ring. Wet with water only.
  3. Using a new gasket, install the water pump assembly to the engine block. Torque the mounting bolts to 17 ft. lbs. (24 Nm).
  4. Connect the hoses to the pump.
  5. Install the timing belt. Refer to the timing belt procedure in this section.
  6. Install the engine drive belts.
  7. Fill the system with coolant.
  8. Connect the negative battery cable, run the vehicle until the thermostat opens and fill the radiator completely.
  9. Once the vehicle has cooled, recheck the coolant level.

Hope helps (remember rated this).

Were is the water pump 1997 dodge interpid 3.5 l


Its the center-most pulley that the drive belt touches.

3.5L Engine

See Figure 5
  1. Disconnect the negative battery cable.

  1. Place a drain pan under the radiator. Open the radiator drain located at the lower right side of the radiator. Do NOT use pliers to open the plastic drain.
  2. Remove the coolant pressure bottle cap and open the thermostat bleed valve.
  3. Remove the timing belt using the recommended procedure. It is good practice to turn the crankshaft until the engine is at TDC No. 1 cylinder, compression stroke (firing position). This aligns all the timing marks and serves as a reference point for all the work that follows.
  4. Remove the water pump mounting bolts and pump. Discard the O-ring seal.
  5. Clean the gasket sealing surfaces. Do not scratch the aluminum surfaces.

To install:
  1. Install a new O-ring and wet with clean coolant. Be sure to keep the new O-ring free of any oil or grease.
  2. Install the water pump and O-ring to the engine block.
  3. Install the retaining bolts and tighten to 105 inch lbs. (12 Nm).
  4. Rotate the pump and check for freedom of movement.
  5. Install the timing belt using the recommended procedure. Verify that all valve timing marks align. This is most important. An engine out-of-time will be seriously damaged when first started.
  6. Be sure that the radiator drain is closed. Open the thermostat bleed valve. Install a 1 / 4 -inch clear hose about 48 inches long to the end of the bleed valve and the other end into a clean container. The intent is to keep coolant off of the drive belt(s).
  7. Slowly refill the coolant pressure bottle until a steady stream of coolant flows out of the thermostat bleed valve. Gently squeeze the upper radiator hose until all of the air is removed from the system.
  8. Close the bleed valve and continue to fill up the coolant pressure bottle to the proper level. Install the cap back on the bottle and remove the hose from the bleed valve.
  9. Reconnect the negative battery cable. Start the engine and allow to run until normal operating temperature is reached.
  10. Check the cooling system for leaks and correct coolant level. Be sure that the thermostat bleed valve is closed once the cooling system has been bled of any trapped air.

Removal
  1. Drain the cooling system. Refer to Section 03-03 for the procedure.
  1. Disconnect the battery ground cable (14301) .
  1. Remove the generator drive belt, water pump and power steering pump drive belt, and the A/C compressor drive belt (if equipped). Refer to Section 03-05 for the removal procedure.
  1. If equipped, remove the three A/C compressor drive belt idler pulley bolts and the A/C compressor drive belt idler pulley.
  1. Remove the upper radiator hose bracket bolt.
  1. Loosen the two upper radiator hose clamps and remove the radiator hose bracket bolt. Remove the upper radiator hose (8260) and the upper radiator hose bracket from the vehicle.
  1. Remove the water bypass hose (8597) from between the thermostat housing and the water hose connection (8592) .
  1. Remove the main wiring harness from the upper engine front cover (6019) .
  1. Remove the eight upper engine front cover bolts and the upper engine front cover .
  1. Raise and support the vehicle.
  1. Remove the RH front wheel and tire assembly.
  1. Remove the four RH outer engine and transmission splash shield bolts and two screws and remove the RH outer engine and transmission splash shield (6775) .
  1. Use Strap Wrench 303-D055 (D85L-6000-A) or equivalent to hold the water pump pulley (8509) while removing the four water pump pulley bolts.
  1. Remove the water pump pulley from the water pump (8501) .
  1. Remove the crankshaft pulley (6312) . Refer to the procedure in this section.
  1. Remove the five lower engine front cover bolts and the lower engine front cover .
  2. Ensure that the timing marks between the crankshaft sprocket (6306) and the oil pump housing line up.
  3. NOTE: The directional arrow is necessary to ensure that the timing chain/belt (6268) can be reinstalled in the same direction.
  4. Loosen the timing chain/belt tensioner nut.
  5. Remove the timing chain/belt .

  6. Installation
    NOTE: Ensure that the timing marks on the camshaft sprockets (6256) and the seal plate are properly aligned. Ensure that the timing marks on the crankshaft sprocket and the oil pump housing are still aligned. NOTE: A new timing chain/belt has three white timing marks that indicate the correct timing positions of the camshafts (6250) and the crankshaft (6303) . These marks will help ensure that the engine (6007) is timed properly. When the engine is properly timed each white timing mark on the timing chain/belt will be aligned with the corresponding camshaft and crankshaft timing mark on the sprocket. Because the white timing marks are not evenly spaced you will need to refer to the following illustration for proper timing chain/belt placement. There should be 40 timing belt teeth between the timing marks of the front and rear camshaft sprockets and 43 teeth between the timing mark on the front camshaft sprocket and the timing mark on the crankshaft sprocket .

    NOTE: Verify that the camshaft timing marks are aligned with the timing marks on the seal plate, and that the crankshaft sprocket timing mark is aligned with the timing mark on the oil pump (6600) .

    Install the timing chain/belt starting at the crankshaft sprocket and moving around to the camshaft sprocket following a counterclockwise path. Do not allow any slack in the timing chain/belt between the timing sprockets. After all of the timing marks are matched up with the timing chain/belt installed, slip the timing chain/belt onto the timing chain/belt tensioner .

1994 Honda Civic LX\overheating within 2 mile drive


Remove and raise upper hose at thermostat end and remove lower rad hose.
Fill rad with a hose and watch for flow from bottom rad hose and/ or bottom rad hose connecton.......water should fall though rad easily.
Honda rads are cheap.....any restriction....replace rad.

Remove thermostat....fill thermostat housing with hose and watch for water flow at bottom rad hose.
Flush good.

Remove heater hoses.......flush back and forth until a good flow is present "With heater control set to hot" if no or poor flow....replace heater core.

Stop leak can plug everything.

Also.......not likely causing over heating....but ....at your mileage,if you do not know if the timing belt has been changed.....CHANGE IT NOW!
Water pump is optional at this mileage.

Dont know where thermostat goes. engine overheating, coolsnt not cycling.


The thermostat is bolted into the bottom of the water pump, the lower radiator hose connects to a cover that holds the thermostat to the water pump.

the thermostat can be difficult to get at because the AC and power steering pump are all bolted on top of the water pump,

Your problem may not be a bad thermostat.
I would also check:

1) water pump, some of the vw pumps are poorly made & tend to go bad.

2) fans belts, it can be tricky to get the right tension on these belts due to a badly designed tensioner system on the power steering & water pump belt.

3) hoses, radiator, coolant tank,. the radiators and coolant tank tend to leak when they get old, the plastic cracks or the rubber seals go bad.
Also check the electrical system controlling the engine cooling fans. there are sensors and relays that can go bad.
I have owned 8 vw's most of the major problems with these cars was due to electical problems.

4) Engine problems such as a blown head gaskets, or ignition timing problems can cause overheating. luckily VW engines usually don't have these problems, unlike other companies 4 cylinder engines (the Dodge Neons for example)
