Here's why:
* Condensation: The combustion process in an engine produces water vapor as a byproduct. When the engine is cold, this vapor condenses in the exhaust system. If the car hasn't been driven for a while, this condensation can accumulate and then drain out as water when you start the car. This is particularly noticeable after periods of non-use or in humid conditions.
* Unburned Fuel: A small amount of unburned fuel can also contribute to the water vapor in the exhaust.
However, the combination of infrequent use and the appearance of water *could* indicate something else, albeit not necessarily catastrophic. It might warrant investigation:
* Coolant leak: If the water is milky or has a sweet smell (antifreeze), it could indicate a leak in the cooling system, which is a serious problem. This needs immediate attention to prevent engine damage.
* Head gasket failure: In severe cases, a blown head gasket can allow coolant to mix with the engine oil and enter the combustion chamber, resulting in water in the exhaust. This would usually be accompanied by other symptoms, such as white smoke from the exhaust, overheating, loss of coolant, or milky oil.
What to do:
1. Check the color and smell of the water: Is it clear, milky, or discolored? Does it have a sweet smell (antifreeze)? Milky or sweet-smelling water is a serious concern.
2. Check your coolant level: Is the coolant level in the radiator low? A low coolant level points to a leak.
3. Check your engine oil: Is the engine oil milky or creamy? This indicates coolant mixing with the oil – a major problem.
4. Observe the amount of water: Is it a small amount of condensation, or a substantial flow? A small amount is likely just condensation. A large amount warrants further investigation.
If you have any concerns about the color, smell, or amount of water, or if you notice any of the other symptoms mentioned above, it's best to take your Ford Laser to a mechanic for a proper diagnosis. Ignoring a potential coolant leak can lead to catastrophic engine damage.
