Don't Underestimate It, Here Are the Bad Effects of a Dirty Fuel Tank Cap

One part of the car that is often overlooked by the owner is the fuel tank cap. This is quite unfortunate, because the effects of a dirty fuel tank cap hole are not trivial.

Its size is indeed very small (only about 1 millimeter) and is located inside. There are a handful of people who do not check it, perhaps because they are unaware of the existence of that hole.

Effects of a Dirty Fuel Tank Cap Hole

So, what will happen if the tank cap is damaged or even lost? Never underestimate it, because the following conditions could occur at unexpected times:

Air Circulation Blocked

The presence of a hole in the fuel tank cap is the only place for air exchange (circulation). This is because the tank is specially designed to have a high level of airtightness.

If the hole is blocked, of course, no air can come in or out. This condition can trigger various problems in the vehicle, both minor and severe.

Causing Rust and Holes

Accumulated dirt will trigger rust on that component. If the blockage is not addressed immediately, rust will cause the mouth of the tank cap to become holed or perforated.

This hole is very risky, as water can enter the tank and mix with the fuel. This condition can lead to further problems, some of which include:

1. Engine performance becomes suboptimal
2. Engine produces a sputtering sound
3. Vehicle suddenly stalls
4. Damages components, including the piston

If that happens, you will have difficulty addressing this damage. At the very least, you will need to drain the contaminated fluid or even flush it out, so the vehicle can function again.

Disrupting Fuel Flow

Air circulation in the tank cap actually has another benefit, which is to support the smooth flow of fuel. When the engine draws fuel to operate, that volume will be replaced by air entering through the hole.

If the hole is blocked by dirt, air cannot enter the tank. As a result, fuel cannot flow properly, causing the engine performance to become suboptimal.

Vehicle Stalling

Who would have thought that a vehicle stalling does not always have to be caused by severe engine damage. A dirty tank cap hole can also cause the vehicle to stall in the middle of the road.

This is because no fuel is being delivered to the combustion chamber, so the engine cannot operate. To confirm this, you can start the engine by removing the tank cap first.

If the engine starts, there is a possibility that the cap is indeed blocked. Clean the hole, then try to start the vehicle again.

Based on the explanation above, it is very important to clean the tank cap hole regularly. You don't have to go to a big workshop; you can clean it yourself at home.

The way is simply to wipe it with a clean, highly absorbent cloth. This way, you can ensure that no water settles in the hole and binds the dust that enters.

However, if the damage is quite severe, it is best to take the vehicle to a trusted workshop, like the following web. There are many benefits you can gain by servicing at an official workshop like Daihatsu, namely:

1. More complete and quality tools
2. Technicians are certainly trained and competent
3. Provides original spare parts and accessories
4. Costs are clear, as there are specific price standards
5. Service history can keep the resale value of the vehicle high
6. Warranty facilities

This means that, although the price is slightly higher, it is very satisfying and your vehicle is guaranteed. No more worries about the effects of a dirty fuel tank cap hole, because Daihatsu provides comprehensive care.
