    Actually I just drove the van about 15 mins. I then parked and the same thing is happening there's coolant leaking on the bottom. But the reserve and the radiator look full. everything looks wet beneath the vehicle.

Do not put water in your radiator. Use 50% mix of antifreeze and water or you will corrode your engine. Add coolant mix to cold engine. Fill the reservoir and the radiator. Warm up eninge while looking for the source of the leak. If lucky, it will be the lower radiator hose. Easy repair. If it's the engine block, big problem. Let us know what you find.

Why water going out from the reserve tank in my batfinder


Your coolant system is leaking water.
Look under the vehicle for signs of the coolant whatever color it may be leaking down the engine.
If you have an automatic transmission, look at the fluid to make sure water is not leaking into the transmission via the cooler in the bottom of the radiator.
Check the tightness of all hose clamps on every rubber hose. Check the condition of the radiator cap and if it is older than 5 years, replace it with a new one anyway.
Take the overflow hose off the radiator and try blowing through it into the reservoir..if the system is dirty sometimes coolant is blocked from going into the reservoir when the engine heats up and therefore is dumped on the ground.
Check the reservoir for cracks.
Check it's cap if this is separate on your vehicle.
Please get back to us with your solution to this problem as it may help someone else in the future.

Is there a manifold gasket that prevents antifreeze leaks or could it be the radiator that is leaking


get the engine hot,
all external leaks , tell you , who leaks.
the cap pressure is 14psi, so it will leak at the pressure
and is easy to see, just look, dont rush, look.
and behold the item leaking, if confused take a photo of the leak.

you had green fluid on the ground. right.
why is this hard?
that puddle says , im leaking and need help fast.
as leaks tend to get worse. what a burned up engine???????

Water reserve bottle is emptying and engine is getting how


flushing a radiator is a waste of time and money as blocked cores do not flush. Have a pressure test done on the coolant system and check for external leaks. have a compression test done to check for head gasket and cracked head. Have a flow test done on the radiator and if shows signs of blockage replace the radiator .. Always fill the radiator at the radiator cap and not the reserve bottle. The reserve bottle water will not go down until the engine coolant starts to cool so if it is going down when the engine is hot then you have a bad leak in the reservoir bottle.

Some Ani-freeze from time to time under van, top radiator hose cold, no heat


You should check the coolant level every week when you have a leak. The level in the radiator is probably low, and it could also have air in the system now. Try filling it up and then check it again tomorrow until you know it is full.

Car is overheating after short drive (3/4 hour) had thermostat changed, put new coolant in radiator. radiator was pressure tested no leaks? car ok short drive to store. resevoir seems always overfilled...


The expansion tank will be more full when hot. Let it cool down and check it then. The level in the axpansion tank should go lower. If not then you may have a faulty radiator cap.
Also have you checked the cooling fan? Engine driven? With the engine off, spin the blade. Does it spin real freely? Continue to spin for more than a quick second? May have a bad fan clutch. They have fluid inside and the fluid can leak out of the seals after age.

My car overheats very easy.i can drive 1 exit on the highway and the temp goes up very fast. i dont know what it could be. there is always fluid in the reserve area and doesnt seem to be getting low or im...


COULD BE THERMOSTAT IF TOP RADIATOR HOSE IS NOT HOT AND BOTTOM RADIATOR HOSE GOING TO WATER PUMP IS HOT THE THERMOSTAT STICKING PARTIALLY CLOSE.IF TOP HOSE IS HOT THE RADIATOR,ENGINE BLOCK HEATER CORE NEED FLUSHING OUT.IF WATER PUMP WEEP HOLE LEAKING REPLACE WATER PUMP, FAULTY WATER PUMP WILL CAUSE ENGINE TO OVER HEAT.REPLACE RADIATOR CAP MAKE SURE YOU HAVE 50 / 50 MIX SOLUTION ANTIFREEZE AND WATER IN COOLANT SYSTEM. IF ALL LOOKS GOOD CHECK ENGINE OIL ON DIP STICK, IF OIL IN DIP STICK LOOK LIKE MILKSHAKE YOU HAVE BLOWED HEAD GASKET THAT WILL CAUSE ENGINE OVERHEATING WHILE DRIVING CAR IN SHORT DISTANCE AND ENGINE OVERHEATING.

Van is losing water but the overflows continues to stay full. No cracks in radiator and the cap where you put in the water has a hose going in but no hose on the opposite opening.


In a properly working system, the coolant expands as the coolant temp rises. The excess coolant flows into the overflow container by the hose that runs from the bottom of the overflow to the top of the radiator, under the radiator cap. When the coolant begins to cool down, it contracts,drawing fluid back into the radiator from the overflow. The water pump has a "weep" hole located near the bottom of the pump housing that will leak coolant if the pump is going bad. In some engines, the 3.0, the water pump is located under the camshaft timing belt cover, and is a BEAR to deal with. However, the coolant should be pulled into the radiator when the engine cools, so check that the hose from the top of the radiator is attached to the bottom of the overflow and that it is not blocked or pinched. Have the system pressure tested to verify that it has no leaks. Hope this helps. Dano

Looking for the fill plug on a 200 dodge darango 4 wheel drive front punkin all i see is a vent pipe


COOLANT-ADDING ADDITIONAL
Do not remove radiator cap to add coolant to system. When adding coolant to maintain correct level, do so at coolant reserve/overflow tank. Use a 50/50 mixture of ethylene glycol antifreeze containing Alugard 340-2 y and low mineral content water.
Remove radiator cap only for testing or when refilling system after service. Removing cap unnecessarily can cause loss of coolant and allow air to enter system, which produces corrosion.

COOLANT LEVEL CHECK
The cooling system is closed and designed to maintain coolant level to top of radiator.
WARNING: DO NOT OPEN RADIATOR DRAINCOCK WITH ENGINE RUNNING OR WHILE ENGINE IS HOT AND COOLING SYSTEM IS UNDER PRESSURE.
Remove radiator cap. The coolant level should be to top of radiator. If not, and if coolant level in coolant recovery bottle is at ADD mark, check for:
  • An air leak in coolant reserve/overflow tank or its hose
  • An air leak in radiator filler neck
  • Leak in pressure cap seal to radiator filler neck
TRANSMISSION and OIL LEVEL CHECK TUBES
