My 2001 Ford Focus is leaking antifreeze?

Question

It is a slow leak. Noticed that it only is leaking when it is cold outside. What could the cause be???

Answer 1

Slow leaks are not concerning and auto makers even acknowledge this by the fact that many add a "stop leak" to the cars cooling system when it is manufactured. The causes are many but more than likely in your case is is due to the expansion and contraction of the aluminum used in your engine components. Aluminum will continually expand and contract as your engines heats and cools. This could be enough to allow a small leak when cold, you should not see anything when the engine is hot.

The safest, cheapest way to address the problem is to add some "stop leak" to the system. I personally like Barr's Stop Leak. It is a liquid (do not buy the powdered form) that has a synthetic coagulant in it. When added to your system the coagulant melts and searches for the leak. When found it fills the gap by solidifying as it passes through the leak. This product also lubricates your water pump. It is safe for all vehicles and will not affedct the manufacturers warranty.

first thing to do is tell it to stop and mean it the car has a deamon that does not like antifreeze.........


now the real answer go to a shop and tell then there they will probably just tighten the clamps the coust is about 10$...plus a little new antifreeze......
