refill DEF tank

Diesel exhaust fluid (DEF) is an essential component of a diesel powertrain. As you drive, the fluid is released into the exhaust stream, breaking down harmful chemicals and reducing emissions. That means that every now and again, this fluid will need to be topped off.

Wondering when to refill your vehicle’s DEF? In most instances, you will be alerted to low fluid levels by warning lights on your dashboard. Since your vehicle needs DEF in order to meet EPA regulations, failing to refill it will result in reduced power and speed. However, your vehicle will return to normal once the DEF tank is replenished.

Tips On Refilling Your Diesel Exhaust Fluid

Diesel exhaust fluid, also referred to as DEF for short, is a necessary component of your diesel powertrain. As you continue to drive your vehicle down the roadway, this DEF is released into the exhaust stream. Its job is mainly to breakdown chemicals in the exhaust system. This breakdown, in turn, reduces the emissions from your vehicle, making it more environmentally-friendly.

Where Is The DEF Tank Located At?

Your diesel exhaust fluid will need to be refilled regularly. You'll find the tank for this fluid typically next to the tank for the diesel fuel. This can vary depending on the specific vehicle manufacturer. It's a good idea to read through the owner's manual to learn where the DEF is stored so you'll be able to easily assess it when your fluid is getting low. You should notice 'DEF' written on the cap for the diesel exhaust fluid tank.

How Often Should DEF Be Refilled?

Since DEF is a fairly new concept that was enacted to meet new FDA regulations regarding vehicle emissions, most vehicles will have electronic alert systems. Just as your check engine light will flash on the dash when there's something wrong with your engine, the DEF light will come on when your fluid level is low. This is the easiest way to determine when it's time to refill your DEF tank.

Ensuring you have an adequate level of DEF fluid in your vehicle will make sure that it runs smoothly and has the power you need it to have.
