All vehicle owners have the occasional niggle with their vehicle. Maybe it’s a mysterious knocking, a rogue warning light or water leaking from your exhaust? Whatever it is, it isn’t necessarily going to be expensive to fix, but it is definitely worth getting checked out by your local garage. Small issues have a tendency to turn into big problems.
In simple terms, engines are powered by a series of chemical reactions which, inevitably, result in waste gases. These gases are released through the exhaust pipe. Sometimes, you will notice drops of water coming from your exhaust. This isn’t necessarily a problem, but by being aware of the causes, you will be better able to identify when you don’t have to worry, and when you need to consult your local mechanic.
A Hot Engine
We all know that heat results in steam or condensation. When you first start your engine, it can take a little while for the oil to lubricate the components. In those first moments, your engine can get quite hot, which means that your exhaust system will be hot, too. Hot fumes and a cool ambient temperature will result in water dropping from your tailpipe. What’s more, once the engine is lubricated and it begins to cool down, the steam in the hot fumes may condensate into trickles of water. If the water only drops or trickles for a few minutes, there is nothing to worry about – you can put it down to the hot engine and cool temperatures. If it continues, take it to your local garage.
Catalytic Converter
Your catalytic converter is designed to reduce the harmful emissions that are released into the environment. Water vapour is a by-product of the emission conversion process, so small water drops are a sign that the catalytic converter is doing its job.
Faulty Piston or Rings
Most of the time, water droplets from your exhaust pipe are caused by changing temperature and are nothing to worry about. However, if you persistently have water pouring from your exhaust, it could be a sign of a much bigger problem. If the water is accompanied by smoke – and sometimes a burning smell – it could be a sign that a piston or rings are damaged. If this is the case, consult a mechanic as soon as possible – ignoring this problem could lead to expensive damage.
