How can I tell if it is my water pump or thermostat that needs to be placed?

My car starts to overheat after driving about 5 miles the water in the reservoir starts to boil over. Then it makes like a squeaking sound that's only happened 3 times Maybe also the hose from the radiator gets very hot and hard no longer is it squishy so I'm pretty sure it's either the water pump or thermostat but since I'm not a mechanic I do not know which is that something y'all can diagnose when you come out to do the repair and do y'all include the part in the price or would I need to order the part?
And I would like to schedule to get this work done on Monday or
Experienced mechanics share their insights in answering this question :
The water pump moves the coolant through the system and the thermostat regulates this flow to maintain operating temperature. If the water pump has failed, the coolant will not flow through the system so the temperature will rise quickly and the heat will be concentrated on the engine. An experienced technician like one from YourMechanic can use an infrared temperature gun to check temperatures along the cooling system and determine whether the problem is the water pump, the thermostat or both. Since the vehicle has overheated already, the thermostat should be replaced along with any other cooling system service.

With the engine off, open your hood and locate the water pump pulley. With gloves on, grab it and wiggle it back and forth. There should be no movement, if there is, this along with the noise is a good indication you may have a water pump problem.
You`ll most likely hear a quiet clicking sound followed by air moving through the ductwork. You can also place your hand on a vent to feel for hot or cold air. If you don`t hear or feel anything within a minute or two of making the changes, your thermostat may need to be replaced.
Start your car`s engine and allow it to idle. Look through the radiator filler neck to see if the coolant flows. At this time, it should not be flowing as your car has not reached the operating temperature to cause the thermostat to open. If you find the coolant is flowing, it means the thermostat valve is open.
Whining or Groaning Noise

A whining or groaning noise usually means that either a drive belt is loose, or the water pump pulley is bad. It may surprise your customer that a pulley could fail, but it does occasionally happen. Pulleys have been known to fail due to rust, which can cause cracking between their bolt holes.

The reason that your check engine light comes on is that the water pump affects your engine. Without your water pump, your check engine light will come on because your engine will slowly overheat.
To check if your pump is operating efficiently, measure the power consumed by the pump and check it against the pumps performance curve. The pump curve will specify how much power you should be using at the flow and pressure your pump is generating. This helps you to identify which pumps are not operating efficiently.
A defective water pump cannot be repaired, it must be replaced with a new one. It is a common practice to also replace the vehicle`s thermostat when doing a water pump replacement. It is not always needed, but if you suspect that your engine got hot when the water pump failed, it`s a good idea to take care of it.
Turn your thermostat to HEAT mode and adjust the temperature until the thermostat triggers a heating cycle. Once the heating system is running, go back outside to the exterior unit – if this equipment is on and blowing air, it`s a heat pump.

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.

I need a thermostat replaced do I need to replace the water pump as well
ANSWER : Typically, the scenario is the reverse: that is the water pump fails and the question is should the thermostat be replaced at the same time that the water pump is replaced. The answer is absolutely because the thermostat itself can be damaged if there is an episode of overheating and, of course, a water pump failure is often associated with overheating. However, if the thermostat itself is the failure, it is only recommended to replace the water pump if it requires a lot of labor to get to the thermostat AND the water pump happens to be adjacent to the thermostat housing. In practical terms, that means that if the water pump is rendered accessible because you are replacing the thermostat then, yes, as a form of cheap insurance against future breakdown, you should go ahead and change the water pump as well, while you are in there. However, if the water pump is not made "accessible" while replacing the thermostat then there is no need to replace the water pump at this time if it is functioning and not leaking. The OEM thermostat is recommended. Sometimes aftermarket thermostats do not work as intended or fit properly. If you desire that a mechanic handle the replacement, please request thermostat replacement and a certified mechanic from YourMechanic will perform the replacement and install the water pump, as well, if you desire. If you have further questions or concerns, do not hesitate to re-contact YourMechanic as we are always here to help you.

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.

If you would like to have the water pump replaced, a certified professional from YourMechanic can come to your car’s location to perform this service at your convenience.

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 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.

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.

Yeah I have a 2001 Seville SLS I’ve been told it needs a water pump thermostat and upper hose what would that cost
ANSWER : Hi Jon. Did you notice any coolant leaking from the vehicle? Any smells, steam, or any evidence of coolant? There may be a water pump concern and the other items being recommended as preventive maintenance. However, without a proper cooling system diagnosis, how would we know for sure? There could be a failing cooling fan causing the high temperature. I suggest having a qualified technician perform an inspection to avoid replacing unnecessary parts. Your Mechanic has several technicians available that can assist you with a car is overheating inspection, water pump replacement, thermostat replacement, and radiator hose replacement.
