2005 Kia Rio. Replaced thermostat and, when I went to refill the radiator with antifreeze, antifreeze started pouring out of the engine as fast as I poured it in. Is it the water pump or a Welsh plug?

    Had you actually read my issue/question, you wouldn't have misdiagnosed, Mr. J. D. Browning. It turned out the water pump, which is on the opposite end of the engine on the Kia Rio, had failed. I decided to have a shop replace it as it involves removal of an engine mount and jacking up the engine, which I don't have the equipment to do myself.

SOURCE: I want to change my antifreeze in my 2003 merc

look down at rad from top to get familiar with where i am talking about. now opposite side of the lower rad hose is where you want to go, two styles of rads, one has a wing nut type white plug, and other as 6 sided white plug, unthread with pliers or by hand loosen till desired flow is coming out. fill into reservior or overflow tank to half way and run engine til i reaches operating temperature and you has good heat out of heater, this makes sure all air is out of system, and this is complete ttop up to full and install cap

SOURCE: I have a 96 chevy

Bad water pump. The seals are more than likely shot. Usually at higher rpm the temp goes down and at idle it would overheat. Had a friend with the same problem.

SOURCE: water is pouring out as fast as I can pour it in

Get someone to pour in the water and then you crawl underneath and look for the source of the leak. Take a strong flashlight.

Where to fine the thermostat on the radiator of a 2004 kia rio

The thermostat will be on the engine block. Follow the upper radiator hose to the engine-the end of the hose clamps on to the thermostat housing-the thermostat is under the housing. Remove the bolts of the housing and pull it off to see the thermostat. Of course, the coolant must be drained first, or you will have a big mess to clean up.

I have a 1999 Kia Credos, water keeps pouring out the Overflow once the car warms up, eventually the car over heats.

make sure that your water to antifreeze ratio is at the proper mix.
there might also be a problem with your thermostat and /or your water pump could be bad and not circulating your coolant properly. check these items and if they are working, then look at your radiator and see if it could have debris inside the channels that are keeping the coolant from cooling properly. you might also need to flush the cooling system.
but check the thermostat first -- and make sure that your water pump belt is at the proper tension.

How many gal of antifreeze should i put in the coolant system? I put 2 gal in as there was little left in the system. I went to drive the truck and within 15 min the truck was over heating. The antifreeze...

Was it knocking in the radiator when it over heated if so you most likely got an air lock in the system by pouring the new antifreeze in to fast. You need to add it real slow and once you think the radiator is full start the truck and let it warm up and leave the radiator cap off until the thermostat opens and then add more antifreeze because when the stat opens the level will go lower. Once you are sure the antifreeze is circulating an full then you can go drive the truck. Some people use a 50 percent mix of antifreeze to water but I always use 100 percent antifreeze it runs cooler.

2005 3.3 caravan heater only provides heat off idle. Fan sometimes does not come on as well. thermostat was replaced twice in summer for O/H.

You probably have air pockets in your cooling system. I have fixed a few of them by removing the Coolant Temperature Sensor just behind the Thermostat Housing. They can be kind of hard to get to on 3.3L Engines. Anyway, remove the sensor and pour antifreeze into the radiator until antifreeze pours freely out of the sensor hole. Then re-install the sensor. You may have to top-off the radiator after the sensor is re-installed.

If this does not fix the problem the you could have a bad water pump. Sometimes the stamped-steel impeller on the water pump gets corroded to the point where it cannot circulate the coolant properly.

Over heating

You need to solve this one fast.

Limited information provided, year, make engine size ect.

Check recovery tank refill tube if it is soft it may not be fully moving the antifreeze back to the radiator when it cools off due to drawing air in to radiator.

Radiator cap?
Drain and refill coolant?

Hope this helps.

2001 Oldsmobile Alero overheating

I think you started out looking in the right places. Replacing the coolant, thermostat, relay and sensor are all fairly inexpensive.

I believe you either have blockage in the system (especially if you're using tapwater), or your water pump may be failing.

I would first either take it to a radiator shop and have them flush the cooling system out thoroughly, or else pick up a chemical flush kit and do it yourself. This involves more than just drain and refill.

If this doesn't work, your next step will probably be replacing the water pump. At almost 200k miles, it's probably about due anyway.

Kia rio 2001 thermostat

Fallow the "UPPER" Radiator Hose from the Radiator to the Engine Cylinder Head, The Thermostat Housing is the Unit that the UPPER Radiator Hose Connects to. Theres is 1 BOLT (TOP) & 1 NUT (BOTTOM) that you Remove to Gain Access to the Thermostat itself. Hoping this Helps you out There . Have A Great Day.
