Where is the reductant heater located in a diesel engine?
Where is the reductant heater located in a diesel engine?
The reductant heater is a component that is used to prevent diesel exhaust fluid from freezing or crystallizing in low temperatures. It is usually located in the diesel exhaust fluid filter reservoir and/or the reductant injector supply hose (s).
How to check the coolant level in the radiator?
Verify coolant level in the radiator and coolant reservoir. Add the recommended for your vehicle as necessary. Consult your car owner’s manual or repair manual. 3. Air pockets: Let’s say that you replaced the coolant a couple of days ago. Now the engine is overheating. But the coolant reservoir tank indicates the correct level. How can that be?
What is the reductant heater control system used for?
The reductant heater control system is used by the Powertrain Control Module (PCM) to heat up the Diesel Exhaust Fluid (DEF) to prevent it from freezing.
Where do I find the coolant reservoir on my car?
Open your hood and locate your radiator and coolant reservoir. Some older vehicles don’t include a reservoir, but most modern vehicles have a small tank for filling and checking the coolant level. The reservoir should be clear plastic, so you can easily see the level of coolant and the maximum fill line.
The reductant heater control system is used by the Powertrain Control Module (PCM) to heat up the Diesel Exhaust Fluid (DEF) to prevent it from freezing.
Where does reductant go in a diesel engine?
Reductant (DEF)Injector • The reductant injector is a Pulse Width Modulated (PWM) solenoid controlled directly by the PCM. The injector receives reductant from the reductant pressure line and sprays it into the exhaust stream, where it is mixed into the exhaust gases before entering the catalyst.
What causes low coolant level in radiator surge tank?
The low coolant level in the radiator surge tank may be due to the fill process at the assembly plant, which cannot purge all of the air from the cooling system and the surge tank. After the engine has been thermally cycled, air rises and causes the coolant to become lower than when initially filled. Coolant Levels
Why does my Duramax engine have low coolant level?
After the engine has been thermally cycled, air rises and causes the coolant to become lower than when initially filled. During a Pre-Delivery Inspection (PDI), the coolant level may appear low, but is at a level high enough to keep the Low Coolant message off.
