Follow this steps and fix it. God bless you

  1. Determine the Reason for Water Pump Failure
    • 1 Repair a water pump by checking your car for a failure in the bearings. You can test for bearing failure by seeing if there is any play in the shaft that is connected to the electrical fan blades, as well as the drive pulley to the pump itself.
    • 2 If you notice any free play in the shaft or the pulley, you will need to take the pump apart and replace the bearings.


    • 3 Determine if the water pump failure is due to a leak in the casing. Examine the water pump housing for leaking or water stains in the drainage hole next to the pulley.
    • 4 If water is dripping from this hole, then the seals inside the pump need to replaced in order to repair the pump.
    Remove the Water Pump for Repair
    • 5 Allow the engine to cool completely before removing any part of the cooling system. Never open a radiator cap or plug while the engine is still warm.
    • 6 Disconnect the car battery. This will prevent the electrical fan from turning on while you are under the hood.
    • 7 Drain the radiator of all fluid and disconnect the radiator hoses. Collect the fluid with a plastic container and keep it in a safe place until you are ready to put it back into the radiator.
    • 8 Remove the fan assembly. This will include the shroud, the fan and the fan belt. Disconnect the electrical leads for the fan.
    • 9 Remove the pulley for the fan belt as well in order to have access to the water pump.
    • 10 Use a socket set to remove the water pump from its engine mount.
    • 11 Open the housing for the water pump and replace the seals or bearing as necessary. Some auto parts stores carry repair kits that have both the seals and bearings for specific types of water pumps.
    • 12 Reassemble the cooling system by replacing the water pump, pulley, fan belt, fan assembly and radiator hoses. Refill the radiator with the fluid.
    • 13 Start the engine to see if the water pump repair was successful. Check for leaks before you take the car out on the road.

SOURCE: Car is leaking antifreeze from underneath of car

watch for leaks and follow them after you drive i would geuss checking your thermostate housing both parts, the hoses that go to the heater core by the throttle body and the hose that goes to the throttle body, im guessing this is the turbo, if it is a non turbo it would be a hoses the waterpump or the oring that goes into the waterpipe on the front of the block, just get in there and take a good luck and remember the rules of gravity =) good luck man and if you need any parts for it let me know we got alot of these parts cars out in our yard

SOURCE: Water Pump

I would check the thermostat first; its the easiest to get to and usually the first to go. Unfortunatly if it is bad it usually takes the pump with it when it goes : ( My Fathers car is going through the same thing. But his pump is bad as well.

SOURCE: 96 honda civic ex runs hot

It is either a blown head gasket or a cracked head. Depending on which motor your civic has, this could be a tricky replacement, either way, you have to remove the head off of the motor, and then take the head to have it pressure checked to see if there is a crack in it. Nine times out of ten though, you can see a crack in the head with your eye, but you have to have the right "eye" to be able to see the crack.

SOURCE: bad leak, dont know if its water pump or thermostat

On the 2.4L engine your water pump is driven by the timing chain and its location is near your thermostat area there is also some seals at metal water pipes at the same general area.the way the water is coming out I would suggest that it is coming out your water pump bearing hole but your cooling system should be filled and pressurized and diagnosed by a professional if at all possible.You want to make sure you are replacing the correct component because a water pump replacement on a DOHC 2.4L can be rather expensive.I hope this helps.

My 2003 regal is running hot and slowly leaking all the coolant out. Can anybody tell me what the problem is?

Yes, you are running hot from leaking all your coolant out. No one can tell you where it is leaking without looking at it. Could be a hose leaking, the radiator, a bad head gasket or intake gasket, the water pump...if coolant is leaking from the front of the engine, that could be the water pump or radiator hose or a water pump gasket. Pretty common for the water pump to leak when it is worn out, that's how you know when to change it.

When you fill the radiator and overflow tank back up to full, does the engine still run hot? If it does, I would not advise running it-have a shop diagnose it before more serious damage occurs. Head gasket repairs can get very expensive-that is the danger you are facing, and if the head gasket has already gone bad from overheating, continued running of the engine can cause you to have to replace the engine. Overheating is a major cause of early engine failure.

Try to determine where the leak is, from where it drips off the engine. The coolant constantly circulates from the engine to the radiator and back into the engine. The heater hoses circulate coolant from the engine to the heater core in the heater case and back into the engine. Besides the overflow tank, these are the only places coolant would be on the car. The engine can leak coolant from a lot of places, but if leaking to the outside, you should be able to spot where it is coming from. Good luck.

Leaking water and running hot 2005 dodge magnum

the solution depends on where the water is leaking from. If it is leaking off the front of the engine from the water pump, then the pump may be bad, not circulating coolant which makes the car run hot. You haven't provided much of a description so it's hard to know what other options you have. But I would start with that. This assumes that there are no obvious leaks from one or more hoses that can be replaced.

2001 chrysler lhs leaking antifreeze when turn car off

After engine has cooled, put water in the radiator if you can, not the overflow bottle.
Antifreeze raining down - sounds like a water pump leak, or other SERIOUS leak, in a rubber hose, etc. You can ruin the engine if it overheats! Guage will not work with no water in the engine. Have reliable mechanic check it ASAP

Losing a lot of coolant. I don't see a leak. I started to drain the system and it smells burnt to s**t. What might my problem and possible solutions be?

see this causes and fix it. God bless you
Water pump -- A bad shaft seal will allow coolant to dribble out of the vent hole just under the water pump pulley shaft. If the water pump is a two-piece unit with a backing plate, the gasket between the housing and back cover may be leaking. The gasket or o-ring that seals the pump to the engine front cover on cover-mounted water pumps can also leak coolant. Look for stains, discoloration or liquid coolant on the outside of the water pump or engine.
Radiator -- Radiators can develop leaks around upper or loser hose connections as a result of vibration. The seams where the core is mated to the end tanks is another place where leaks frequently develop, especially on aluminum radiators with plastic end tanks. On copper/brass radiators, leaks typically occur where the cooling tubes in the core are connected or soldered to the core headers. The core itself is also vulnerable to stone damage. Internal corrosion caused by old coolant that has never been changed can also eat through the metal in the radiator, causing it to leak.
Most cooling systems today are designed to operate at 8 to 14 psi. If the radiator can't hold pressure, your engine will overheat and lose coolant.
Hoses -- Cracks, pinholes or splits in a radiator hose or heater hose will leak coolant. A hose leak will usually send a stream of hot coolant spraying out of the hose. A corroded hose connection or a loose or damaged hose clamp may also allow coolant to leak from the end of a hose. Sometimes the leak may only occur once the hose gets hot and the pinhole or crack opens up.

I have 2002 chevrolet tahoe with 150000 miles that just started pushing out a quart of water every 3 days. just replaced thermostat and have had radiator flushed every 30000 miles . is the problem water...

Try to locate the source of the water loss. If it seems like it is leaking from the front in the center of the engine, then look under the water pump and see if it is coming from the weep hole. If it is coming from that hole the water pump has failed and needs to be replaced. The best time to check it is with the engine hot and sometimes it needs to be running depending on how bad the leak is. If it seems like it is coming from the front of the engine but near the sides check to see if you have a split hose.

My 2006 charger 3.5 is leaking coolant but only somtimes is it a sign of water pump malfunction no indications on the gauges but car seems to be running hot

this is most likely the water pump if it is leaking at front of engine, the water pump is under the large timing belt cover and driven by the timing belt, so both are changed at the same time.

My honda accord wagon smells hot i stop running car, ther,s no leaks do i need a termostat?

You may have a bad thermostat or a weak water pump or a clogged radiator. Smell does not indicate if its hot. The gauge or coolant light might suggest its getting hot. You may have a fuel control issue that is overheating the catalytic converter which would smell or an oil leak that is dripping onto a hot surface causing a smell. You may have a real small coolant leak that you cant see that could cause this also.

if you see the water leaking form the front side of the engine usually from the water pump since the pump is not running you also wont get heat, bit when you pressurise the sys you are forcing the hot water into the core and you have heat, it is the water pump.

Chevy cavalier 1997 2.2 coolant leak

Alright, the best way to find a leak is to fill the reservoir and get it up on ramps or a car lift would be excellent. Start the engine and find out where the leak is coming from. Most common leaks are simply just bad hoses or busted fittings. However, there could be a blown head gasket, hole in the radiator, or a bad seal on the thermostat housing.

I've even seen where a bad thermostat was causing high pressure in the water system and ended up blowing the excessive pressure and water out the overflow, even when the water was actually low. So, find the location of the leak. Use the method I told you and it will help you find the exact location. Then you can proceed on fixing the leak.

Hope this helps out! :)
