There are a few things that could be causing the clunk. One possibility is that there’s something wrong with your engine mounts. If these mounts are damaged or worn out, they can’t properly support the engine, leading to a clunking noise.

Another potential cause is a problem with your transmission. If the gears aren’t properly aligned when the engine starts, you may hear a clunking noise.

There are also a few other things that could be causing the problem, so it’s best to have a professional take a look at your vehicle to determine the cause. If you’re experiencing this issue, it’s important to get it fixed as soon as possible, as it can potentially cause damage to your vehicle.

Why does my engine knock when cold?

Your engine may knock when it’s cold because the fuel-air mixture is too rich. When the engine is cold, the air intake is cooler, which causes the fuel to be more dense. This can lead to knocking because the fuel-air mixture is too rich and there’s not enough air to support the combustion process.

Another thing you can do is to make sure your engine is properly warmed up before you drive. You can do this by driving at a moderate speed for a few minutes before you increase the speed. You can also let the engine idle for a few minutes before you start driving.
