I can't keep antifreeze in my car but its not leaking anywhere, what's wrong?

Question

Every couple of days I have to top up my antifreeze and everyday I check and it's not leaking any where, where can it be going, and what can I do to fix it?

Answer 1

you might have an internal leak....
IT might just be getting burned up .....
OR seals are busted....


(the quickest way to find a leak ....is to get some of that green fluorescent die, to add to the fluid..................when you heat up your car and the coolant starts to circulate, use a BLACK light to look for the fluorescent leak on the out side of the engine.

, if it's head gasket (depending on the car but you are looking at serious cash)

Answer 2

I own a shop, and can tell you that you have a leak somewhere. Take it to a shop that can pressurize the system, and you will find the problem. Many leaks can't be seen, but can be found with a pressure test, and/or use of dye. If its an internal leak in the engine, I have used some stuff (with total success) for such problems, but one must follow the directions to the letter in order for it to work. This stuff is called "Block Seal" and is made by a company called "K&W". This is good stuff, and I have seen engines with a blown head gasket seal up. I saw an engine with a crack in the side of the block at least 1/16 of an inch wide, and 4-5 inches long seal right up. That is what convinced me. Like I said, you must follow the instructions to the letter.
Glad to help out, Good Luck!!!

Answer 3

You have a Blown head gasket the antifreeze is leaking into the cylinder and getting vaporized during combustion and exiting through the exhaust pipe you need to get it fixed as soon as possible the antifreeze will cause many problems internally in your engine, fouling spark plugs, washing the oil from the rings of the piston, causing rust to form inside the engine block and rusting out the exhaust system from the inside out.

Answer 4

It very well could be your head gasket but check for external leaks or signs of external leaks, especially around the seep or vent hole on the water pump(you might have to get a mirror and light to check this) there shouldn't be any signs of leaks there(like streaks of dried fluid usually white) and also check around the core hole plugs(you might call them freeze plugs) they can start to seep then get progressively worse without even noticing till one burst apart or pops out under the pressure. Before you condemn the head, gaskets or block have a pressure test done and a compression check. Some auto parts stores will lend or rent these tools or some rental shops have them but if you do not understand how to read them and understand what the readings mean it might be better to have a shop do the test for you. Oh yeah, this is an after thought. Check around the heater core inside and outside of car for any signs of leakage(floor, firewall, etc)

Answer 5

It could be puking into the overflow and leaking out while you drive. You'd never notice it. It happens in my 64 Impala alot. It will consistently leak down about an inch, then stop.

Or, it could be leaking past the head gasket or a crack in the block and going out with the exhaust. That's bad. But usually you can tell that be seeing bubbles in the radiator coolant when you run the engine with the radiator cap off. No bubbles probably mean that's not happpening.

Answer 6

Check your exhaust--Is the smoke white? Then if so, you have internal problems with head gaskets or something worst such as a cracked block or head!
Also, check your oil dip stick! It may be going there also!!
Water pump weep hole or seals, radiator-cap or hole in radiator, or just something simple like a hose clamp with a slow leak or a freeze out plug.
If you're adding anti-freeze, you have a leak somewhere!
Park the car on a piece of cardboard which might help locate the leak area more easily.

Answer 7

sounds like it might be a bad head gasket. That's what my problem was. The antifreeze was escaping through the exhaust. One sure way to tell is to crank the vehicle, then go to the exhaust pipe and look for a light steam and possibly the smell of antifreeze. Hope this helps.

Answer 8

could be million things. check your engine oil and see if it looks milky if so then it can be a leaking head gasket and can cause serous engine damage, ensure its not boling back into the bottle overflow if it is try changing your radiator cap, thermostat simple stuff. it can be a very very small leak and hard to see very well could be waterpump this isnt uncommon, could also be a your heater core leaking which in this you will uaully find some mositure in the passenger side floor board. carpet will be wet. etc.. check all these things, are take it to a radiator shop or somewhere have them check everything for you. Good luck,

Answer 9

Does the car let out white smoke from the exhaust pipe? You could have a blown/leaking head gasket. If it isn't smoking then you have a small leak around the radiator that is unnoticeable. Also check your hoses at or around the heater core.

Answer 10

Check your radiator CAREFULLY . The end tanks on my son's ford p/u are leaking ,but they never leave a puddle. The heat of the radiator evaporates the coolant before it can run down to the ground. Look for coolant colored crystals and/or a slimy spot on crimped edge of the tanks. I hope this helps ,otherwise the others are right about the head or manifold gasket. Good luck!
