My mothers water pump, and radiator hose has been changed, the radiator has no holes and everything is working fine, weather it has just water, or half water, half anti-freeze it still boils and overflows when she turns the car off. I could fix it if i had any possible idea what the problem was.

Let the engine cool, remove radiator cap, start the engine let it warm up.
Make sure the radiator is full. Look in the radiator for a bubbling mist. that is the sign of a bad head gasket. Also caddies with aluminum blocks require special coolant.

SOURCE: water pump still leaks 92 cadillac deville

I hate to tell you this because I know it isn't an easy task changing the water pump but if it is coming between the block and the water pump housing you need to pull it back off and make real sure it is very clean by scraping the old gasket off and putting sealer on the gasket. Every bit of the old gasket has to be removed before putting the new gasket on. You could try and tighten down your bolts a little but be careful not to break the bolt or you then have another problem.

These engines are know for leaking head gaskets. A good quick test for this is fill the coolant tank to the top with the cap off. Start the engine. If the the coolant blows out of the tank, you have a head gasket leak.

How do i know if my water pump is bad on a G6

Disconnect the top radiator hose at the radiator, plug the hole in the radiator where the hose attaches, and put a garden hose in the radiator to keep it full of water.
Start the engine, and if the water pump is working, the water & coolant will pour out of the top hose.
Remember, the thermostat must already be open, or it will not flow until the thermostat gets hot enough to open.
(Or, if the pump is leaking whilst the car is running, or if the pump is "screaming" whilst the engine is running.)

My Chrysler Concorde 2000 3.2? Overheated and melted a hole in the water resivour tank,so we replaced that, it still got hot fast, so we replaced thermostat, then it started making a loud noise it sounds...

The whistling noise is steam. The problem is you never attacked the source of the problem. What you need to do now is drain your radiator completely at opening T-spicket at the bottom of the radiator. While you drain with engine off, run your water hose on top, to flush out the radiator. Then run to the Auto store and buy "radiator flush" -- follow directions. After flushing out the radiator flush, close the T-spicket, and fill with NEW anti-freeze. By enough to fill to the very top. Mix the anti-freeze with water per instructions to your environmental weather.
Buy a new radiator cap which could have caused the problem in the first place by not allowing the correct pressure to blow off. Being a 2000 car is a little early for radiator problems, but an incorrect anti-freeze solution causes radiators to fail prematurely.. Better to have more than less because anti-freeze keeps the radiator from corroding.
Your radiator never cooled the water sufficiently, and boiled much of the water out, hence it got so hot that it would melt the water tank. The Thermostat could well have been the cause because it got corroded from the inept ant-freeze mixture. Did you find rust on the Thermostat ? If so it was the case. If not the radiator has lost cooling either by low water or the cores have become plugged up, in that case you will need a new radiator. See if the flush loosens the rust within the cores before buying an expensive radiator. Check the water hoses if leaking cooling. Run the car allow the engine to become hot before accepting that your water hoses are fine. Because heat expand everything, and may not leak until after the expansion.

Leaking anti freeze from water pump screw

Most water pumps have a weep hole that leaks when the pump seal is broken. Usually indicates the water pump needs replaced.

1994 toyota pickup 4x4 sr5 v6 overheats after changing coolant

Sounds like your water pump may be not working, while vehicle is off try squeezing both upper and lower radiator hose you should be able to feel the fluid in the lines and the hose should feel firm and not squish all the way together. Make sure you used the right coolant orange vs green and mix ratio. after all this has been confirmed start vehicle and squeeze hoses again before they get to hot to make sure the fluid is moving and now hoses should be pretty hard to squeeze at all while the truck is running. if you don't feel movement of fluids or hoses are very squishy it could be a vacuum leak and worst case your water pump, hope this helps-

My 2004 STI is overheating.

Since you mention DON'T MENTION HEAD GASKETS I won't. It is more than possible that your problem is entirely with your water pump. It happened to me this year. Old pump was leaking from the weep holes,very, very , hard to see. Finally replaced the water pump with a NEW not REMANUFACTURED pump and the NEW pump was defective. Engine continued to overheat. I felt like you feel now. I checked the new pump after removal and I had to do the same job over again. If you remove water pump you will see the tracks from the weep holes. If this is the case for you I hope you have saved your HEAD GASKET. Good Luck Friend.

Lower radiator hose stays cold after running for hours

could be you fitted the thermostat in the wrong way around ,or the plastic impeller on the water pump with a steel drive shaft has failed they end up with the drive shaft spinning but the impeller is not turning ,go for the thermostat first though .

My 1990 toyota corolla is getting hot really fast - i fill radiator up and after 5-10 min the water has evaporated - it appears to be leaking somewhere around the right side of engine (facing front of car)...

Well there are only 3 things that could have gone wrong.

1. Radiator Leak - this means the radiator has developed a hole with via corrosion of the metal parts of simply integrity failure of the plastic parts of the radiator.
2. Hose leak - this could be a hole in 1 of 2 hoses that connects the engine to the radiator. Or it can also be a leak where the hose connects to the radiator (clamp Failure).
3. Water Pump breakdown - this is where the gasket in the water pump has failed and is leaking out the water rather than pumping it.

All the problems above has different ways of diagnosing. but we can probably narrow it down.

1. if the leak is near the radiator then it could be a hose connection, hose breakage or Radiator hole.

2. if the leak is nearer the engine then check the other end of the hose and if its not there then it could only be the water pump is leaking. You can check this if there are water stains on the water pump. The water pump on a 1990 corolla is mechanical turned also by a fan belt. Look for a pulley that has a hose connected to the radiator and that would be the water pump.

The rust that you saw may come from the engine, the metal parts of the radiator or the water pump itself. Removing the hoses for cleaning is fine as long as it is returned to their proper places. For the sources of the rust check first the radiator cap for corrosion, you may need to have it replaced as well. Check out the metal coils of the radiator if there is rust build up. To get to the water pump you will have to remove some serpentine belt and the timing belt to get to it. The work that will be used to get to it and replacing it is almost the same as in replacing a timing belt. Make sure to check the timing belt while at it to save time and labor. Whenever I replace my timing belt I also have the water pump checked and replaced if needed.

My 2002 hyundai sonata, help:)

cold weather won't usually hurt anything in your heater, it will just take longer to warm up the cabin.

the lack of heat is a sign that you're probably not getting the proper circulation in your cooling system, that is, the radiator, anti-feeze/coolant, fan, etc.

bad circulation means your anti-freeze level could be low from a leak, or a hose that popped off. or you could have a bad water pump, which is what circulates the coolant through the engine and radiator, even though we don't use water anymore.

the solution is to have someone who knows how check the thermostat, radiator, coolant level, hoses, and water pump to make sure everything is working.

be sure to address the problem soon, because if it's a coolant system problem, the more your drive, the more damage your engien will suffer.
