My coolant is disappearing but theirs not one drop on the ground..?

Question

Where else could it be..

Ive checked the oil dipstick and oil cap they seem fine and their is no milky color it just looks normal

Answer 1

FIRST, if it IS a blown head gasket it WILL run hot and there WILL be steam coming out of the exhaust pipe even after the vehicle has reached operating temperature. Just because it has a blown head gasket doesn't mean there will be water in the oil and vica-versa. However, if it is a cracked block or cracked head there WILL be oil in the water and water in the oil. I had an old Chevy truck one time that was doing this very same thing. It was losing water from the coolant system over a period of time BUT not running hot. After racking my brain and checking everything I knew I come to the conclusion it just might be the radiator itself. I took it off and took the radiator to a radiator repair shop and had it pressure tested. The test showed there was a small pin hole just under the lip of the top of the radiator. When it got hot the coolant would SEEP from the hole and down on the radiator coils. Then it would evaporate leaving no visible sign of leakage. I had my radiator rodded out and fixed the hole in it then reinstalled it. I have had no more problems with loosing coolant. If you need any more help just click my icon and contact me.

If there's no leakage under the water pump's shaft where the weep hole is, then I would simply keep driving the car as long as it wasn't overheating and you only have to add a cup or two of coolant every few weeks. Sometimes a small leak will correct itself. Then if it gets worse, it will be easier to find the leak. Just make sure that the radiator is always full, especially if it has a separate radiator cap in addition to the overflow bottle cap. If the water pump's leaking, you'll need to get it fixed.

Answer 3

I would check the oil dipstick to see if there is anitfreeze mixed in with oil or you could have a blown head gasket that struck a leak between the cylinder bores which mean youre actually burning the fluid out through the exhaust.

Answer 4

check your rubber hoses for small leaks , it could be leaking and burning off the engine before it hits the ground to puddle , but more then likely you have a blowen head gasket which is letting the coolant to leak in to the oil and is being burned up by the engine which is bad for your engine the anit freeze/coolant will brake down your oil and your cars motor will over heat and Suez up and you will be looking at new pistons if not a new motor

Answer 5

i had the same problem, my head had very bad electrolysis " pits in the head" i didnt see any typical signs of oil in the water or gas bubbling from my radiator that would indicate a bad head but that is what it was, there is a sure fire way to tell if it is leaking into your cylinders take out the spark plugs and see if any of them have a lot of carbon built on one of them, and what was weird about my situation i had all my ground wires connected and everything it was the water i used it had a high ph when i put it in the coolant it caused electrolysis and that is one of the main causes another weird thing is that i did a compression test and it all came out great but it was still leaking water real slow it stomped me for a long time till i checked the plugs

Answer 6

crack in the block,,,

1) then mix with oil,, see your oil level,, if it's milky

2) then stright into chamber ,, see if back of car is slimey

now what to do???

ARE YOU SHOR IT'S NOT DRIPPING?? run the car for 10~ 20 min parked .

well both cost lots, as it be a whole engine repair or buy a new one,,, which in the long run is better

cheep way ,,,see how much Litres per miles you loseing

if not lots,, you can buy a filler as the crack not bad,, but this will not last

best is to fix it good, best of luck
sorry

Answer 7

Blown head gasket. The coolant is being deposited as steam out of your exhaust system. Very common problem, especially from cars with alloy heads.

Answer 8

Could be a leaky heater core. It is atomizing the coolant and you may be breathing this stuff. Do you have the smell of coolant in the interior? If not, then it could be a leaky intake manifold gasket or head gasket.

Answer 9

If it's not leaking then it's going through the motor somehow. Bad head gasket? Have you checked the oil?

Answer 10

You could also have a leaking radiator cap or hose, a small leak will go undetected, plus if it is the radiator cap then it will on leak while the engine is hot.
