You may have a small leak in the head gasket. Have the plugs pulled and inspected for signs of coolant incursion into the combustion chambers. Also check the crankcase oil on the dipstick to see if any milkiness is visible and the coolant overflow for any signs of oil mixing with the coolant. If this is the case, eventually you will have ignition misfiring when cold until heat buildup rids the plugs of coolant.

Why is my car losing antifreeze but there are no visible leaks, even under pressure??


Usually means you have a head gasket leaking coolant into the cylinders and the engine is burning it out the exhaust pipe. Once the leak gets bigger than what the cylinders can burn, it will show up in the engine oil.

You're losing the antifreeze probably due to a leak. Look under it for a puddle. if no puddle, tighten all hose clamps and have the cap tested, if it's ok, you need to pressure test the cooling system to try to see the leak. If you still can't find it, it may be a head gasket or cracked head.

My car loses antifreeze, No sign of leaks.


If you are sure it has no leaks and this has been verified with a pressure test being done by a shop then you may have a leaking engine cylinder head gasket. I would suggest that you get under the car and look for white powdery deposits that are left by coolant leaks, also have the system pressure tested, this requires a special tool.

Antifreeze leak comimg from where antifreeze enters engine


The antifreeze enters the engine through the water pump. If it's not a hose, the water pump is leaking. Have a mechanic pressure test the system.

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.
