My car has coolant leak, I already replaced the thermostat, and it is still leaking. From watching videos on YouTube there possibly can be more like a faulty water pump or loss of pressure.

There are multiple areas that can leak, water pump failure is common. The easy way to find it would be to rent/borrow a cooling system pressure tester, fill the cooling system and put it under pressure. Then just look for the leak. It should be readily apparent.

This guide should help with the water pump replacement instructions below.

After driving approx. 60 miles the day before upon seeing the car the next morning in the garage loss of all coolant visable under the car. I suspect the water pump or a broken hose. Radiator appears to be in good shape. But really cannot tell.
How do I detemine the cause of this problem before taking it to a repair shop? It is an expensive repair for the water pump and I would like to be sure that is the problem.
It there a test to perform? With the bottom plate on the undercarrage it is difficult to view.

Thank you.

The easiest and quickest way to locate the source of your leak is to fill your system with coolant and start the engine.

Allow it to idle until it reaches opperating temp. (When your fans come on) Then look around the engine compartment utill you find the leak.

REMOVAL
The water pump on all models can be replaced without discharging the air conditioning system.

WARNING: DO NOT REMOVE PRESSURE CAP WITH THE SYSTEM HOT AND UNDER PRESSURE BECAUSE SERIOUS BURNS FROM COOLANT CAN OCCUR.

NOTE: It is normal for the water pump to weep a small amount of coolant from the weep hole (black stain on water pump body). Do not replace the water pump if this condition exists. Replace the water pump if a heavy deposit or a steady flow of engine coolant is evident on water pump body from the weep hole (shaft seal failure). Be sure to perform a thorough analysis before replacing water pump.

1.Drain cooling system. Refer to Cooling System, Service and Repair, Service Procedures.
2.Remove accessory drive belts.
3.The water pump is driven by the timing belt. Refer to Engine for component removal to provide access to water pump.

4.Remove water pump mounting bolts. Note position of longer bolt for proper re-installation.
5.Remove water pump body from engine .

INSTALLATION
1.Clean all O-ring surfaces on pump and cover.


https://www.2carpros.com/forum/automotive_pictures/12900_wp1_6.jpg



2.Apply Mopar(R) Dielectric Grease or equivalent to the O-ring to facilitate assembly. Install new O-ring on water pump.
3.Position water pump to engine.
I4.nstall mounting bolts and tighten to 12 Nm (105 inch lbs.) .
5.Install timing belt. Refer to Engine for procedure.
6.Install accessory drive belts.
7.Fill cooling system.

My check engine light came on, I took it into the dealership and they changed the water pump.
Now, I noticed where you put coolant in, seems to drain quicker than usual. No visible leaks under car. Help?

Check the motor oil to make sure there is no coolant in there. If there isn't, rent a pressure tester from a parts store and check the cooling system to see if there are any leaks.

Open the car hood and locate the thermostat on the top of the radiator lid. Pull the thermostat and start the car. Watch the temperature gauge carefully. If the water pump is working properly, the engine should take a long time to warm up (if it ever does). With the thermostat removed, the coolant should circulate continuously, making it harder for the engine to warm up. If you cannot tell if the car is heating up slow or not, move to next step.
Turn the car off and locate the water pump and the water pump drive belt in the engine compartment. Use the wrench set to loosen the belt retaining bolt and pull the belt off of the pump. Spin the belt drive with your hands to see if it rolls smoothly and to determine if there is any movement or "play" in the driveshaft. If the pump seems in good working order, replace the belt, tighten the retaining screw back up, and move on to next step.
Locate the coolant drain plug on the bottom of the radiator and use the wrench set to remove it. Allow all of the coolant to drain out into a container and dispose of it. Replace the drain plug in the bottom of the radiator and then pour coolant into the radiator. Start the car up and watch the level of coolant carefully. If the water pump is working properly, the coolant level should drop quickly as the pump circulates coolant to other areas of the engine. Fill the radiator back up with coolant and watch it to drop again. If the coolant drops then your water pump is fine, however if the coolant drops very slowly or not at all it may be time for a new pump.

I'm getting my water pump replaced and I would like to know what parts do I exactly need for this? I've been told I would need to replace timing belt and all the componets related to that, which is what I'm lost on. What componets would that be?

It is very much the same job all you have to pay extra for is the parts as it is all have to be removed to get to the pump
I would recommend also to do it to
