Is EGR valve same as EGR cooler?
Is EGR valve same as EGR cooler?
Light-Duty Engines A portion of the exhaust is channeled through an EGR control valve and proceeds to the EGR cooler. From the cooler, EGR flows to a throttle valve assembly where it is mixed with filtered, high-pressure, fresh combustion air that has been cooled by an intercooler to recover some of its density.
How to replace the EGR cooler on a VW T6?
Tried removing the valve from the old cooler and no chance, much hammering and prying and broke it out, black and minging inside but didn’t look choked, little vacuum valve was sticky compared to new but hard to tell much about the egr valve itself… But no sign of oil or water where it shouldn’t be
How does the EGR cooler work on a diesel engine?
The cooler in your truck’s EGR system works with the EGR valve to create a mix of air, fuel, and exhaust gases that reduce emissions. These EGR coolers are a known weak point on most diesel engines, which leaves a lot of questions for owners.
What happens if the gaskets on the EGR cooler fail?
If the EGR cooler gaskets fail, or the cooler gets damaged for any reason, it can cause an exhaust leak to develop. An exhaust leak may be heard as an audible hissing or tapping sound coming from the front of the vehicle. This will reduce the efficiency of the EGR system, and negatively affect engine performance. 3. Check Engine Light comes on
How does faulty EGR valve cause turbo failure?
The valve ensures the EGR system is disabled at idle, when it would otherwise lead to erratic idling, and at peak power, when adding exhaust gases would reduce power output. The EGR valve is likely to stick and become coked up on some applications. BTN Turbo warns that this can have a significant effect on turbocharger performance.

What happens to the coolant when the EGR valve is closed?
Cooled when the coolant flow removes heat and the EGR valve is closed, and then heated and stressed as hot exhaust gases pass through. Each time it heats up, the metal inside the cooler grows and strains against the restraints of the unyielding metal shell, causing stress and strain.

What happens if my 6.0L EGR cooler fails?
If this cooler fails or the coolant passages become clogged (a common occurrence on the 6.0L), it may reduce flow to the EGR cooler, or create a sludgy oil/coolant mix that won’t flow through the cooler.
