If you cant find the leak there is a good chance that the problem is the head gasket. It could also be the heater core your windows would fog up with the heater on if it is the heater core. look under the hood for the leak when the car is hot you should see some steam from where it is leaking.

If it has a 3.1L or 3.8L engine there is a good chance that its leaking fron the intake manifold seen on the right of the engine when facing it. Where abouts does it drip on the ground at ?

How to check for leaks of antifreeze/in 97 expedition smell of antifreeze


Hi Sharlene,so you smell antifreeze.Raise your hood and check your antifreeze over flow container,you should have a l and a h mark on it,high and low.If low,then it's leaking somewhere,look at the radiator cap and overflow hose for leak,look at over flow container for leak from hose going to it from radiator,look all over engine,look at top and bottom radiator hoses and clamps for leaks,if leaking there,tighten clamp with flat head screw driver,if no leak is found,get under vehicle and see if any antifreeze is visible,maybe water pump,look on ground for leak and follow,check floor board on driver side,heater core could be bad,check hoses going to heater core from engine firewall.

The car was bone dry on antifreeze. while driving yesterday could smell antifreeze and i have no heat


prob heater core, roughly 750 to replace, whole dash needs ripped out..unless it is just a hose off at the firewall leading to the heater core or leaking radiator hose..fill the system with clean water and look for leaks, you wont have heat without enough collant in the engine to circulate under 13 psi closed system, check the resevoir for cracks and leaks mine fell apart over years good luck

Antifreeze pushing cap on over flow resivore and low heat .Could this be a leaking head gasket? antifreeze not draining back out reservoir


It sounds like you need a new Radiator cap for the overflow style Radiator. The overflow style has a recovery vent which draws the water back through the radiator neck and into the engine. Low heat levels are also a sign of a water shortage.

Your antifreeze strength needs to be 50/50. This sounds like there is an ice block inside the Radiator or engine. Get the strength of the antifreeze tested.

You could have an internal leak; you need to have the system pressure tested. The overflow tank should drain back into the radiator and it relies on a sealed system to work. If you have a leak, there will be no Vacuum pressure to draw the antifreeze back into the engine.

It could be a head gasket leak, or a leaking heater core, or bad radiator or a bad hose. The pressure test can be done by anyone with a gauge. You could try Autozone or Oreillys for their loaner tools. Ask for a Radiator tester pump. You can also have the cap checked.

Radiator and A/C shops do this test routinely. A real Service station used to do this routinely until they went self-serve.

I hope my solutions give you a few alternatives because a head gasket is a costly repair. I hope you find my solutions very helpful.

My 2002 for taurus runs out of antifreeze every 2 weeks. I don't see a leak anywhere. Also, sometimes I can smell antifreeze when standing in front of the car, near the hood. Is it possible it is...


No, it can't burn it, the engine would seize if it would do that. The antifreeze is lost thru evaporation - this is why you smell it. Check the radiator cap and the overfill tube and bowl.

2003 saturn ion adding antifreeze every 2 weeks cannot find leak


There should be a radiator cap as it controls what goes into the overfill tank. You might consider replacing it. If there are no leaks in the radiator or hoses, there are only 3 places the coolant can go (water pump leak, blown gasket, or out throught the radiator cap). Hope its the cap because that's the cheapest. Good luck!

My vw passat 98 leaks antifreeze once a while


dear friend-if there is no visible leak then i think you should pressure test and look for leaks,if no leaks is found then look at the heather tank if you overfill the bottle it will push the excess water out that is normal
also check the radiator cap,if it holds the pressure

Antifreeze leak only when car cools down


There should be no anti-freeze under the valve covers, just valves, rockers, springs, and oil. If you are getting any antifreeze leaks at the valve cover then you have a cracked head. Since the engine has been pressure tested and has passed, my guess would be that the coolant reservoir is overfilled. Drain it down to the correct level and see if it does it again. If you are getting a strong sweet antifreeze odor when the car is running, you may be in need of a heat core. My PT Cruiser would leak sporadically, and after running a pressure test, it turned out that the 16 pound radiator cap I had on the car was losing pressure at around 8 pounds. so it would only lose antifreeze when it was really hot and/or I was running the AC.
