Question about 1991 Mitsubishi Montero

1 Answer

I replaced the water pump on a friends Montero but a buddy that was helping me made things alot harder for me. Most of all the bolts that had to be removed to install the water pump, are now mixed up. I have spent the last week an a half trying to find where they go. I've looked in the manual, online and anywhere else I could think of. So, my question to you is where do the bolts go or where can I find information that will tell me where the bolts go? Please Help Me!!!

    Not really but thanks tho. Also just FYI, when replacing the water pump on this vehicle, you will come across quite many different sizes and threads. Also I just finished the job about an hour ago.

Most manuals, even factory service manuals don't list the size of the bolts and their location. If you were to gain access to an exploded parts diagram they sometimes show the location of bolts and list their size in the parts description. You may have to go to the mitsubishi dealer for that though as the listings online don't show what you need.
You should be able to figure out where the bolts go by taking your time. You can break them up into groups by size, length, type etc to make it easier. If the bolt fits it most likely will be just fine.

Your water pump is driven by the timing belt; to access you will need to remove the forward portion of the engine (pumps/alternator/belts and such) when replacing the water pump you wll need to remove and then replace the timing belt and tensioner. Much care is needed to to insure the proper timing or things can go very bad. On a scale of 1-10 (1 being the easiest) I'd give this a 6.5 to 7.

I hope this may have assisted you,

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 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.

3.1L Water Pump

I have done this myself.

If you have worked on other things on your rodeo....

I would put the water pump as harder than putting in a new radiator, but easier than putting in a new alternator.

If you've done anything like a radiator/alternator before, have the right tools, and the Haynes book for the 1992 rodeo, I'd say it would not be too hard. An afternoon of work.

You might want to have a bottle or two of "break free" to get some of those bolts.
