When you stop the engine heat is still being generated inthe engine from all the hot bits. As there is now no water circulation through the radiator these cause local boiling which pushes the watemp right up. The pressure generated by this rise in temperature opens the cap expelling water. I would find the cause of the engine running hot to start with. Faulty fan /fan motor,failed viscous fan hub, thermostat blocked radiator are a few starting points

Water is constantly getting into my diesel. There are no leaks in the diesel tank. Can you suggest where the water is coming from


I'd bet your tank Cap seal is not good. Lots of rain? And or moisture is condensing inside the tank. Another thing to check is the fuel return line from the injection pump to the tank is properly sealed. Water in injection system is deadly especially to the pump. So find the problem soon. you may want to put "fuel dryer" (methanol) to remove any residual water. Oh, Did you stop along the way? Is the cap locked? Or lid locked. With that much water you may have had some vandalism. Any enemies?

What does the thermostat do


the thermostat will open once the water temp in engine block reaches the required temp and will open and shut as the engine temp changes whilst engine running. Also if water level was extra low it would pay to leave radiator cap off and engine running until working temp is reached and top up water until air bubbles stop coming up and out at cap. replace cap and ya good to go.

I have a 2006 ford escape limited 4 wheel drive the water pump went out and now i need to know how to bleed the air out of the cooling system?


just run the car with the rad cap or resavoir cap if no rad cap off and continue topping up until no more bubbles come out. reving the car up to about 2000rpm will speed up the prosess because the pump will circulate the coolant faster. then when level doesn't go down and no more bubbles place the cap back on. If there is a small screw valve on top of the thermostat housing unscrew until air stops coming out and a steady stream of water is seen. tighten and enjoy

Car loses water from overflow cap. Replaced water pump, thermostat and overflow bottle and cap.


Stop me if this has NOTHING to do with your problem (or if it's already been solved)...I don't know a lot about cars so...My Ford Taurus kept overflowing antifreeze from the reservoir cap. Car started to over heat and kept spilling"/dumping" antifreeze every time I turned the car off. The antifreeze reservoir had been replaced less than a year prior, and water pump, radiator, etc looked at. I got a free estimate that stated my water pump was NOT the issue, but I did need a new radiator and my reservoir tank needed to be replaced (again)....$800 parts and labor.... However...I noticed the overflow holes on the tank, and also that the orange liquid (antifreeze), was also spilled around the cap lid. I also noticed the CAP on the antifreeze reservoir would loosen when tightened completely- hence, not sealing correctly. So I went to the dealer, bought a new reservoir cap for $15, replaced it, and never had an issue after! I also found out that the CAP was a DEALER PART ONLY, and when the tank itself was replaced, the CAP was the OLD one! Problem fixed! Maybe it's similar? Or something "more serious".

Finishing water from the resevoir after every 20 km or the water is usually dripping from the resevoir when i stop.golf 4 2000 model


Hi,
Looks like your radiator cap is broken, check if the seal and the spring is still okay.
Water that is not coming back to your radiator means, your cap's seal is loose or chipped off.
Check that first and tell us what happen, give us the temperature of your engine too, thus your engine overheats constantly?
Hope that helps you!
Thanks for using Fixya!

Where do the two hoses from the water reserve tank run in Jeep Grand Cherokee? One is the radiator..... There is another that is hanging and appears to be leaking water. When I drive, stop, and turn off...


The coolant reservoir has a line from the radiator,that is connected near the radiator cap,the other one hangs down for overflow,the radiator cap might be weak,so replace it with the one the vehicle calls for,if this does not stop then there is a problem,have it checked out,if this was at all helpful,please rate,thank you.

Water comes out of the over flow bottle(i checked the cap)


make sure you dont over fill the radiator bottle past max, something else to try is run the system with out the cap on for a few minutes at idle to expel any air pockets in your cooling system.

Coolant comes out sometimes when I stop. Not


If its getting a bit hot - some coolant could come out of the over-flow..
Maybe from a fan not working or getting week..

I have a 1996 nissan sentra gxe.... I just replaced the radiator today and the car still over heated, my only thought as to what the problem could be was the water pump. how do I change the water pump?


sounds like you have a thermostat problem also did you bleed the cooling system of all the air before you put the radiator cap on?
if you have not bleed the system and there is a air lock you will have over heating problems.
the way you can try bleeding the car is let it get up to temp with the rad cap off and let the fans cycle twice and wate till all the air bubbles stop stop coming out.
if the air dosn't stop coming out for a long long time you may have a blown head gasket
