Engine failure is a very serious and expensive problem. Not only could it write your vehicle off, but it could also end up catching fire in the worst cases, putting yourself and your passengers in danger. This is why it’s important to notice the warning signs of engine failure before the van engine actually fails.
This way, repairs can be made that will be far less costly than replacing the entire engine. So, what should you be looking out for to catch engine failure early? In this article, we’ve detailed eight signs that your engine might be failing so that you can stay on top of maintenance and engine repairs in order to experience as little van downtime as possible:
1. There is a warning light on
The most obvious sign of possible engine failure is seeing the engine light come on on the dashboard. While the engine light could indicate a wealth of problems, if the light does appear, you should take it to your mechanic as soon as possible so as to avoid further problems.
VanServ is able to carry out van engine diagnostics and repairs on your vehicle, regardless of its size, its manufacturer or its use. Whether you use your van for business or leisure purposes, you can rest assured that VanServ will be able to carry out expert van engine repairs when you need them most. If your engine warning light comes on, then bring your van to our dedicated garage for seamless repairs that will stand the test of time.
2. Your engine is constantly overheating
If the engine is overheating regularly, then this could be a sign that engine failure is at play. Driving a van that is always overheating can cause even more issues, including a warped cylinder, which can cause the coolant to leak. This will cause the exhaust smoke to be white, which is another sign of engine failure.
3. Fuel economy decreases
If you find that your van is using more fuel than normal, then it’s time to have the engine checked for problems. While there might be other reasons for a drop in fuel efficiency, if you’re experiencing this alongside any other signs we’ve touched upon, then it could be a sign of engine failure. Make sure you have the vehicle checked over by a qualified mechanic, such as the experts here at VanServ.
4. You’re experiencing a loss of power
Petrol-powered vehicles convert petrol into power using four separate strokes in a combustion cycle. This occurs within the internal combustion engine. The vehicle will run as it moves through the strokes. If you can feel the loss of power while the vehicle is in motion, then this could be a sign of engine failure.
This happens as a result of an interruption in one of the strokes during the combustion process. Therefore, the engine will struggle to run if such an internal problem is present. If the engine isn’t running as it should, then you need to take it to a component van mechanic, like the professionals we have at VanServ.
5. The engine keeps stalling
When your van is sitting in idle mode and the engine stalls, then this is a sure sign that engine failure is imminent. This likely indicates an issue with fuel delivery, making it a simple repair, in theory. There could be some other factors involved that make the repair a little more complex, which is why you should bring it to your van mechanic in order to be absolutely sure of the problem and the solution.
6. It sounds rough when idle
This happens when your van is sitting in idle mode, such as when you’re waiting at a red light. If you feel your vehicle shake or vibrate, even when you aren’t accelerating, then this is something known as ‘rough idle’. This means your van engine isn’t running at a consistent RPM, which can indicate a significant issue. There are some simple repairs that could be done to rectify the problem, which should be done by a specialist van technician, such as our team here at VanServ. Among some of the possible fixes, we can:
- Replace spark plugs
- Test/replace your ignition coils
- Check your fuel pressure
- Clean your air flow metre
- Give your engine a tune-up
7. There are some general excessive noises & vibrations
If your engine is failing, then it can present itself in the form of noise and vibrations. Some of the noises that you might experience that indicate imminent engine failure are hissing, popping, backfiring and knocking. These sounds indicate an issue inside the combustion flow.
You might also find that backfiring noises and vibrations come in combination with each other. This could be down to faulty or worn spark plugs. If spark plugs are the problem, or even the coil pack, these are simple fixes to make. But it should be done as soon as possible so as to avoid further engine damage.
8. Smoke is coming from your bonnet
If your van is emitting smoke and it’s rising from the bonnet, then this is a sure sign that there is something wrong with your engine. It could be caused by a number of things, from a fault with the turbocharger to an oil leak or even a blown head gasket. Often, the colour of the smoke can indicate what’s wrong. If the smoke is black, then your engine has incomplete combustion, which can lead your van to burn too much fuel. This could be a result of:
- Damage to the fuel injectors
- Malfunctioning sensors
- Damaged air filters
- Clogged fuel return line
- Mechanical damage to the engine itself
If, however, the smoke is grey, then the list of potential causes could be extensive, with some possible reasons being: a stuck PCV valve, problems with transmission fluid or excessive oil consumption, to name just a few. If the smoke is dark blue, then it means your engine is burning oil. This could be down to an oil leak that’s seeping into the engine’s combustion chamber. There are also several reasons for this, including worn-out piston rings, damaged valve seals or other worn or damaged engine components.
