How a Bad Diesel EGR Cooler Can Impact Your VGT Turbo

Gross sales Highlight: Diesel EGR Cooler Package

Not All Diesel EGR Coolers Are Designed The Identical

Diesel EGR coolers use engine coolant to scale back exhaust fuel temperatures earlier than the fuel is recirculated via the consumption system. Decreasing exhaust fuel temperatures is vital for lowering NOx emissions. Plus, engines that run with larger EGR temperature don’t adequately cool the combustion, which might scale back the life expectancy of the EGR valve, engine valves, and head gaskets.

However not all diesel EGR coolers are the identical. The unique tools EGR cooler’s fin-and-tube-style design is liable to clogging and leaking.  Moreover, many aftermarket EGR coolers function varied tube designs that don’t present the mandatory cooling. Offering a superior different to each designs, BWD® is proud to supply a diesel EGR cooler with an upgraded 20 spiral tube design. Check out our DEK1 above, for instance.

Examined to Guarantee OE Cooling Effectivity

Most aftermarket suppliers fail to adequately take a look at their EGR coolers for correct efficiency. We topic our diesel EGR Coolers to 100% manufacturing unit testing for air and water leaks. To see how our Diesel EGR Cooler performs towards each the OE and our aftermarket rivals, see the outcomes of our warmth trade take a look at above. Notice that autos with exhaust fuel temperatures not within the optimum temperature vary are vulnerable to failing NOx emissions inspections.

The Advantages of a 20 Spiral Tube Design

The OE EGR cooler includes a tube-and-fin-style design that’s liable to clogging from soot and to inside leaks from fractures brought on by overheating. To deal with the design flaw, our diesel EGR cooler includes a 20 spiral tube building that resists soot clogging and prevents leaks to take care of correct system movement and strain. Plus, our design supplies the identical cooling effectivity because the OE design.

Indicators That Your EGR Cooler Wants Alternative

If the EGR valve isn’t working correctly, it might result in costly repairs or complete engine failure. Changing this small half is usually the simplest method to hold your engine working as easily as doable.

That’s why it’s necessary to be careful for warning indicators that your EGR cooler is failing.

Be careful for white exhaust steam or smoke popping out of the tailpipe. This often means the cooler is both cracked or leaking on account of gasket failure. If the coolant seeps out of the valve, it should combine with the exhaust and begin to boil because it strikes via the engine, which causes the fuel. It might additionally imply there’s condensation on the cooler, which might result in steam.

A leak is a leak. In case your EGR cooler is cracked or leaking, you’ll have to switch your coolant extra usually than you’d usually, on account of all of the waste. In case you discover your engine is gobbling up extra coolant than regular, the cooler could also be damaged.

The EGR valve will flip black over time as carbon builds up within the tube. If the cooler fails, coolant will begin to combine with the carbon, which creates a sticky, tar-like substance. Be careful for soiled or sticky surfaces when analyzing your engine. When you have a severe leak, the coolant could wash away the carbon fully, leaving you with a clear EGR valve. If the valve seems to be moist or moist, you in all probability have a leaky cooler.

If the cooler is cracked or leaking, there’s additionally an opportunity the exhaust fuel will leak into the EGR cooler. This may push coolant out of the overflow bottle, which ends up in overheating.

When you have a leak and an excessive amount of coolant enters the engine consumption valve, it might result in what’s generally known as hydro-locking, which damages the interior elements of your engine. Coolant doesn’t compress like air and gasoline, which places added strain on the combustion chamber, together with gaskets, rods and bolts.

EGR valve and cooler leaks usually activate the “Examine Engine” mild. Examine the EGR system when inspecting your engine.
