Is the water pump internal,or external on a 2003 Mitsubishi Outlander

Is the water pump on a Mitsubishi outlander internal or external. 2003
Experienced mechanics share their insights in answering this question :
Hi there – the water pump on this model is on the external face of the engine block, as are most water pumps. However, it is "behind" the timing belt components, which must be removed to change the water pump. On engines with this arrangement, it is generally a good idea to replace both water pump and timing belt components at the same time, since they have similar service intervals, and the labor activities and labor time are pretty-much the same for both. For assistance, I recommend a water pump replacement and a timing belt replacement performed by a mobile, professional mechanic, such as one from YourMechanic, who will come to your location, diagnose this problem, and give you an accurate assessment of damage and cost estimate for repairs.

About the water pump:

Usually located underneath the timing belt or to the side of the front of the engine, the water pump is a key part of your car`s cooling system. The water pump is vital to your engine`s operation because it ensures that coolant keeps moving from the radiator and into the engine.

To get rid of the heat, the coolant inside the engine is pumped to the radiator by the water pump. The pump is usually located on the front of the engine and is driven by either the serpentine belt or the overhead cam timing belt.
About Water Pump Replacement

A failing water pump can also leak causing further loss of coolant. Water pumps are designed to last at least 100,000 miles, however, if your water pump fails, you should replace it with a high-quality original-equipment level unit.

Most water pumps are mounted on the front of the engine block. In today`s crowded engine bays, many parts must be disconnected and removed to access the water pump.
The water pump, often referred to as the coolant pump, circulates liquid coolant through the radiator and engine cooling system, and is powered by the engine itself. It ensures that the engine temperature is maintained at a safe level while operating.
The water pump is a crucial part in your vehicle`s cooling system. It draws coolant out of the radiator and pumps it through the engine. As the coolant circulates through your car, truck, or SUV`s engine, it draws heat away from engine parts to keep them cool.
Water pumps are driven by the timing belt and usually last around 100,000-150,000 kilometres. Most manufacturers do a good job of making quality pumps, so it is fairly unlikely that you`ll run into trouble with one. However, problems with your water pump can still happen.
The pump is mounted on the front of the engine and is driven by a belt which also drives the alternator. Water pumps wear out through age, through lack of lubrication on older types — which need greasing — or because the drive belt is too tight.
Replace the fan, pulley, radiator shroud (if so equipped) and drive belts. Adjust all belts to the proper tension, and fill the system with a 50/50 antifreeze/water mixture. Reconnect the battery ground cable, start the vehicle and check for leaks.
Water Pump is positioned between engine and radiator and is driven by a belt pulley system, timing belt or fan belt to circulate coolant forcibly.
The central heating pump will usually be located near to the boiler or the hot water cylinder in non-combi systems. It`s also worth checking to the rear of an airing cupboard. In older houses, central heating pumps can also be located under floorboards.

Can a jeep run and drive without a water pump??
ANSWER : Driving or running the engine without the water pump working to circulate the coolant through the motor will cause the motor to overheat and may damage the engine costing thousands of dollars versus using a tow truck to take the vehicle to the shop that will cost a lot less. I would not recommend running the engine more than a few minutes at a time or you will overheat it.

My water pump is leaking but I replaced timing belt and pump a year ago. Can I just replace the water pump this time?
ANSWER : Hello. You can just replace the water pump in this case. Although, the cost of just the timing belt is fairly negligible in comparison to the total labor of the job. My estimator says the water pump is a 6.5 hour job. Multiply that by whatever the shop rate is and you have the total labor without parts. You end up saving about $100 or less on parts if you only replace the pump.

The deciding factor will be the condition of the timing belt. If it has problems, you won’t be saving yourself any money by reusing it. In addition, there are seals and pulleys that may need to be replaced as well.

Assuming all the related parts were replaced the first time around, there isn’t a reason you can’t reuse them. I would say you should weigh the savings of reusing them against the actual condition of the parts. This is best determined after a complete disassembly. Keep in mind, time estimates will vary a bit depending on many factors. Either way, the labor is the largest cost.

I have a 00 deville I just changed the water pump housing and water pump the thermostat and radiator the upper and lower radiator 2000 Cadillac De Ville
ANSWER : Hi there – I suspect your radiator is clogged or otherwise corroded so that it is not shedding heat as efficiently as it should. Idling with the heater on was getting rid of heat without loading the radiator. When you’re driving, the engine is generating more heat than both the heater and radiator can get rid of. Checking the difference between hot coolant going to the radiator (top hose), and going back into the engine (bottom hose) may show that there is very little temperature difference. This means the radiator is not doing it’s job, and need to be professionally cleaned or replaced. Good diagnostic effort on your part to avoid the obvious "it’s another Northstar head gasket" diagnosis! For confirmation, I would recommend an overheating inspection by a mobile, professional mechanic, such as one from YourMechanic, who will come to your location, diagnose this problem, give you an accurate assessment of damage and cost estimate for repairs.

Does the water pump need to be replaced if the water pump belt is showing signs of wear? Or just the belt?
ANSWER : Hi, thanks for writing in. There is no reason to replace the water pump every time the belt is changed, unless the pump itself is damaged or not working properly. The belt may show signs of wear which is fairly common between 80k-100k miles. I would not recommend putting the belt service off as this can cause major damage if the belt were to snap. I would recommend having an expert from YourMechanic come to your home to inspect your belts to determine when and if they would need to be replaced, while at the same time inspecting your water pump and cooling system to be sure there are no issues with it.

I had my timing belt and water pump replaced 45000 miles ago. Now I am told I need to replace water pump. Is this normal?
ANSWER : Hello there, 45,000 miles is a short lifespan for a water pump on your 2000 Honda Odyssey. There are a few reasons the water pump will need to be replaced, such as a pump bearing failure, water pump seal leak, or rust/contamination damaging the pump. Faults such as rust or particles in the cooling system are formed in the cooling system over time and the parts break down, or regular coolant flushes are not performed. These particles can cause the pump to fail prematurely. It would be a good idea to ask why the water pump needs to be replaced or take note of any symptoms you are experiencing with the car before moving forward with this. If you would like to have an expert give you a second opinion on this, a certified technician from YourMechanic can come to your location to inspect the car and replace the water pump if necessary.

My water pump just dumped all its fluid. Is it safe to drive my truck if I fill it back up with water without a new pump?
ANSWER : Anytime there is no or low coolant in a vehicle, it can be very harmful to the engine. Low coolant can cause a seized engine or a blown head gasket.

It is recommended that you have the vehicle towed to a location to have the cooling system repaired. If you can, refill the engine with coolant, and if the fluid does not run out as quickly as you put it in, then you may be able to drive a short distance to a safe location, but it is not recommended.

If you need assistance, get a mobile mechanic, such as one from YourMechanic, to inspect and determine the source of the leak, and replace the water pump, if needed.

My car still overheats, I replaced water pump and thermostat, and now after water pump install it knocks bad
ANSWER : Hi there:

Trying to diagnose an overheating issue remotely is incredibly difficult. However, there are three things you can do to attempt to solve this issue. First, remove the water pump, verify it’s the right replacement part and reinstall with new gaskets. Second, flush the radiator coolant fully, as the issue could be caused by an obstruction inside the heater core or other coolant lines. Third, make sure to check all electrical connections to the radiator sensors and components. If you check and complete all three of those tasks, and you still have overheating problems, contact a professional mobile mechanic to complete a car is overheating inspection.
