While waiting for the traffic light at the roundabout, car suddenly made this loud noise. Went home and found the source, anyone ever experienced this before?

It’s Sunday tomorrow and kinda desperate so was hoping to get some answers here before sending to workshop on Monday.

It’s a 2018 Perodua Bezza.

Bracket holding the water reservoir loosen or broke?

so what's the source?

I don’t know if there was a bracket there before, but I searched on YouTube and watched other people replacing the tank.

All screws seem to be in place.

The source of the loud rattling noise is the coolant tank (don’t know if that’s the correct name”.

Still don’t know what’s causing it to rattle and vibrate. The screws on the side and bottom are in tact.

radiator fan shaking?

I see the fan spinning but the fan itself is not shaking (only part I see vibrating / shaking is the tank itself)

Seems like the coolant tank rattles when the fan is spinning though.

Here's what I found from the internet:

"Why is my coolant reservoir shaking?
One of the most common causes is a blown head gasket, in which the air pressure inside the cylinder heads is transferred to the cooling system. This escaped air causes bubbling in the coolant/antifreeze reservoir, which can often be mistaken for boiling."

Hope it helps. But have you solved your issue already? If yes, what was the actual cause of it?

Bro, just go to mechanic shop and ask them check it out.. A lot of us here are not real mechanics..

agreed, if there is nothing wrong with the car, no temp go up, no weird engine power loss, no jerking and etc, it might be the thing it self, go ziptie that thngy hahahah
