Step by step on how to replace a dodge stratus 2005 water pump and Thermostat.

Obviously check all the pipes, other than that pressure test it for head gasket fault...........

Water pump making noise , could depending how worn it is . Before you have a bunch of parts changed why don't you take it to a reputable repair shop an have checked out .

Are the cooling fans coming on ? Go under the hood in the engine compartment , with the vehicle running have some one turn on the A/C , do you see and or hear the cooling fans come on ? Could be the coolant temperature gauge is bad ! How many miles on the vehicle ? Ever have water pump replaced ?

After you replaced the thermostat did you run the engine with the radiator cap of for 20-30 minutes? If you did not then chances are you have an air bubble in your cooling system. If you remove your radiator cap and run your engine for 20-30 minutes that should solve your problem. Be sure you have extra water or coolant on hand when you do this because you may lose some during this process. If you want you can look in the tips section of this site. I have a step by step instructions as how to do this on there. I hope this helps you out.

Instructions Things You'll Need:

• Drain pan, Pliers, Socket wrench, Socket set, metric

2.0L and 2.4L Engines
1. 1 Locate the thermostat by following the upper radiator hose if your car has a four-cylinder engine, or the lower hose if your car has a six-cylinder engine. The hoses are thick rubber hoses that run from the radiator. The other end of the appropriate hose attaches to the engine block at the thermostat housing. Place a clean drain pan below the thermostat housing, then disconnect the hoses from the housing. To remove the hoses, squeeze the tabs on the clamps with a pair of pliers. Make sure that the coolant drains into the pan.
   
2. 2 Unbolt the coolant outlet connector from the thermostat housing to reveal the thermostat. It is held in place by two bolts. Remove and replace the thermostat and gasket underneath. Bolt the connector back in place and reattach all hoses you disconnected in the previous step.
   
3. 3 Refill the coolant tank with the drained coolant. Run the engine with the radiator cap removed for at least ten minutes to bleed air from the system. Replace the cap.
   

hope this hepls you.

thermostat housing was repalced on 2004 dodge stratus but is stil leaking from a hose. what could the problem be.

How to Replace a Water Pump
DIY Complexity: Moderate
DIY Time: 3.5 hours

Parts:
1. Water Pump

Tools:
1. Screwdriver
2. Scraper
3. 3/8 in. Drive Ratchet
4. Cooling System Pressure Tester
5. Needle Nose Pliers
6. Socket Set
7. Radiator Hook Tool

Supplies:
1. Coolant
2. Silicone Sealant

Steps:
Step 1 * With the engine off and cold, open the hood and locate the vehicle’s water pump.
o Tip: Safety Tip:Always wear safety glasses when working on your vehicle. Wear other personal protective equipment (PPE) when necessary, for example latex gloves or safety shoes.
o Tip: Before removing the radiator cap, squeeze the upper radiator hose to verify that the cooling system is not pressurized.

Step 2 * Remove the radiator cap.

Step 3 * Install cooling system pressure tester. Apply the pressure indicated on the radiator cap or in the owner’s manual.

Step 4 * Inspect cooling system components for leaks.

Step 5 * Place a drain pan under the radiator. Open drain valve or remove the lower radiator hose to drain cooling system.
o Tip: Depending on the vehicle, lifting the vehicle may be required to gain access to the lower radiator hose.

Step 6 * Remove the drive belts or serpentine belt.

Step 7 * Remove any hoses connected to water pump.

Step 8 * Unbolt water pump from engine. Remove the water pump.

Step 9 * Using a gasket scraper, clean the mating surface on the engine block.

Step 10 * Install new water pump and new gasket. Tighten bolts to manufacturer’s specifications.
o Tip: You may want to use a light bead of silicone designed for water pumps.

Step 11 * Re-install any hoses and belts that were removed.

Step 12 * Re-install drain plug or lower radiator hose.
o Tip: Squeeze the radiator hose. If it feels soft you may want to replace the hose at this time. Always use new hose clamps.

Step 13 * Refill radiator with a 50/50 mix of coolant and distilled water, then pressure test the cooling system and check for leaks.

Step 14 * Fill overflow reservoir with same mixture.

Step 15 * Leave the radiator cap off, start engine and let it idle. You should see the system“burping” bubbles of air. Refill the radiator to the top.
o Tip: Most air is expelled after a couple minutes of idling. Be cautious of potentially hot fluid overflowing.

Step 16 * Install radiator cap.

Step 17 * Road test vehicle, keep an eye on the engine temp gauge if vehicle runs hot, there still might be an air pocket in the cooling system. The cooling system should be topped off after vehicle has fully cooled down.

Good luck (remember rated this help).

The water outlet housing if installed properly, shouldn't leak. The only way to build up too much pressure would be for the thermostat to be stuck closed. I would find out where the leak is coming from before I went any further. Use the bleeder screw in the housing to bleed the air out of the system.

CHECK ANTIFREEZE IN RADIATOR.IF LOW ADD COOLANT.CHECK FOR LEAKING RADIATOR HOSES AND WATER PUMP HOSE.ALSO CHECK RADIATOR FOR LEAKS.IF ALL GOOD NO RADIATOR LEAKS.REPLACE THERMOSTAT.IF STILL OVER HEATS AFTER REPLACING THERMOSTAT .CHECK COOLING FANS FOR OPERATION AND COOLANT SENSOR.ALSO CHECK TO MAKE SURE WATER PUMP WEEP HOLES IS NOT LEAKING.BECAUSE A BAD WATER PUMP CAUSES OVERHEATING ALSO.

It sounds like a bad water pump. Start by checking hose first. then check thermostat gasket , then check water pump. Replace radiator cap. It is not releasing pressure causing the pressure to find the weakest point somewhere else.
