Well thats kind of a trick question in a sense yes the water will flow however when the car is running you wont be able to see the water flowing because of the amount of fluid on the radiator, you should never really have the cap off unless you are adding/changing the fluid if you open them too often the seal will wear out and your radiator will boil over/out and cause overheating and damage to the engine

The way it works is that the water in the radiator will sit there and not circulate when the thermostat is not open until operating temp. is reached. Once it is reached you should see the water in the radiator circulate at this time.

What would cause antifreeze to come out of the overflow of the reservoir?


Remove radiator cap when car is completely cold. Refill radiator look to see circulation when cap starts turn heater high. When thermostat opens water will be drawn from overflow into radiator. If this does not occur faulty thermostat is probable cause if no circulation change water pump. Refill water to correct levels and car should run correctly

How do i change the radiator fluid?


Most radiators have a drain plug on the bottom tank the engine block also has a drain plug . Remove the radiator cap ,open both drains ,let all the coolant run out, if there is no radiator plug remove the lower hose , remove the heater demister hoses, with the heater control on hot flush out all the coolant from the heater radiator. with a garden hose, till the water runs clean, tighten the radiator plug or re fit the hose,put a garden hose into the radiator and flush out till the water at the block plug runs clean ,refit the heater hoses, refit the block plug, fill the radiator from the hose leave the cap off , If it has a overflow tank clean and flush it. start and run engine for 5 minutes top up radiator if needed . stop engine and drain out all water. most important that all old coolant is drained out, only buy the best coolant you can . If you make up your own use only distilled water. keep some to top up with never mix with another brand. Fill radiator with coolant top up over flow tank, run engine top up coolant as needed, refit radiator cap run for another 10 minutes check for leaks,

How do you know if the water pump failed?


If the bearing failed, it will howl or be noisy. If the pump seal failed, it will be leaking coolant from behind the pulley- through the "weep" hole at the bottom of the pump. If the impellers on the pump that push water through are worn down, it won't leak or be noisy, but your coolant circulation will be impaired, and maybe critically impaired if worn down severely - some pumps use plastic impellers that wear quicker than metal ones. One way to check is with radiator cap off the warm engine (so the thermostat is open and coolant will flow from engine through the top hose into the radiator) and look inside the radiator to see if coolant is flowing in through the top hose. If unsure, squeeze the top hose as tight as you can to stop flow through hose, then release. You may feel the surge of coolant behind your hand as you release hose and you should see the coolant in the radiator moving. If still unsure, have a tech or mechanic check for coolant circulation.
Be very careful opening radiator cap on a warm engine. Turn engine off first. You may want to use a heavy rag on top of cap. Turn cap to first release and wait until any steam or pressure is gone. If coolant is hot it may scald you, and it may be under enough pressure that turning cap to first release will cause hot coolant to start coming out the radiator filler neck where cap sits. When pressure is gone go ahead and remove cap (turn some more to second release-then remove cap). With cap off, start engine and check circulation.
Good luck.

Water failure to engine vstra 1.6 16v 1999


There are several possible causes. Start with the cheapest solution.

1. If you are using water instead of anti-freeze, the water will boil and will get pushed into the overflow tank. Replace the water with anti-freeze.

2. The radiator cap could be bad, allowing hot coolant to exit the radiator and flow into the overflow tank. Have the cap tested or just replace it. It's a cheap item.

3. A leaky head gasket is allowing combustion gases to pressurize the cooling system, which pushes the coolant past the radiator cap. You can easily diagnose this by carefully removing the radiator cap and, with the engine running, observing if there is a continuous stream of bubbles in the coolant. These bubbles are exhaust gas, and you will need to replace the head gasket.

No heat also overheats within 5 minwhen i drive it. new radiator new radiator cap new themistat.


seems like you might have a bad head gasket remove radiator cap and let it run. make sure the antifreeze is flowing if not it could be the water pump prop many car makers are using plastic props and they fail with time.also very possible that thermostat is bad was it overheating before it received a radiator ,cap and thermostat if so it is between head gasket.,and water pump but if you have no flow it is possible that the water pump prop is broken .there is head gasket test that can be done most shops have them and cost a little to do.to be sure.

How to drain radiator


hello. on the drivers side of radiator is a drain. here is a picture and the instructions for draining the coolant out.



  • Install a tube on the radiator drain. Place the end of the tube in the drain pan.
  • After the engine cools down, remove the radiator cap.
  • Completely open the radiator drain ****.
  • Allow the coolant to drain from the system until the flow stops.
  • Place a drain pan under the block drain hole plug.
  • Remove the drain hole plug from the engine block.
  • Allow the coolant to drain from the block until the flow stops. There may be more drainage from the radiator at this time.
  • Install the block drain hole plug.
  • Close the radiator drain ****.

    I have a 85 2.5 4 cyl fiero. I replaced the water pump and thermostat. Still over heat, seems as if water is not flowing thru system. Please help


    Air in the system might be the culprit. There are several techniques out there but filling the system with car level on the ground will not get all the air out. Without getting all the air out, it will overheat. I believe one of the techniques is to fill the system (at the thermostat housing) with the rear end lifted and the radiator cap off until the fluid flows out at the radiator. Then put the radiator cap on and finish filling it up. Also make sure your electric fan on the radiator is working as well as the temperature switch on the engine. I was having trouble with the fan relay and it wouldn't bring the fan on. Additionally at idle, there just doesn't seem to be enough flow so the temperature tends to rise when sitting at idle for any length of time. Unless you live up north, you may want to remove the thermostat. Down south, my engine heats up just fine without confining the water flow and with the limitations in the stock system, you'll never have a problem of running it "cool" anyway!

    This car runs hot when idleing but is fine at highway speeds. I just replaced the water pump and had the radiator rodded out. the electric fan is running fine and moving air well.


    The thermostat might be stuck open. If it is then water running into the radiator is not spending enough time there to cool off before flowing back to the engine block. At speed the increased airflow is having a greater cooling effect while blowing through the radiator fins. With the car totally cool, open the radiator cap and then start the car. Watch the water flow in the radiator. If it is flowing straight through right from the start, you'll know it is the thermostat. It should sit in the radiator until the engine reaches opening temperature and then the flow begins. As soon as the cool water from the radiator reaches the thermostat, it closes and the flow stops. So constant flow equals bad thermostat, flow then stop then flow equals working properly.

    Overheating 2001 pontiac aztek


    remove coolant.remove thermostat remove bottom radiator hose to water pump.put a empty container under the radiator.take a water hose put it where thermostat goes flush out the rust in block.watch the water as it come out the water pump .if stream water is small keep flushing until you get a study sream of clear water. also flush out radiator. lower water pressure dont flush radiator it with high water pressure you could burst it. make clean the over flow jug .make sure it not stopped up.put in a new thermostat and radiator pressure cap. fill radiator with half antifreeze and half water.bleed the coolant system.

    Overheating


    hi check your thermostat, waterpump, radiator and cap, hoses, fan if you can see a visible leak then i can talk you through a solution if its not leaking try flushing radiator, change the cap, make sure your fan is working, make sure your water pump is working u can test by removing the radiator cap with the engine running you should be able to see the coolant flowing not just sitting still if you need more assistance let me know
