Why do you need a Dura-Lite CAC test kit?

Here’s a quick look at some of the risks you take when regular CAC testing is neglected:

Reduced Fuel Economy

If the engine’s power is reduced at a given RPM, then the engine is working harder and burning more fuel. Low power and reduced fuel economy are the best indicators of a leaking CAC if measured carefully and trends plotted. Of course, there are many factors that affect fuel economy, so the data must be compared for similar trips or periods.

Engine Overheating

In the worst case, as the CAC really starts leaking excessively, the cooling system can have trouble removing all the excess heat from the engine. An overheating engine can cause significant damage in a short period of time, such as premature piston, ring, and valve failure.

Soot in Engine Oil

Soot occurs naturally in every diesel engine; it’s why your oil turns black so quickly. In a normally operating engine, the small amount of soot that accumulates in the oil won’t change the viscosity of the oil or affect its lubricating capabilities. However, in cases like a leaking CAC, soot can become excessive, thicken the oil, and leave deposits in the engine. Left untreated, it can clog your oil filter or in the very worst case, clog up an oil passage and cause permanent damage. Soot sticks to components in your engine and is abrasive, accelerating wear. Soot can be measured in an oil sample if it accumulates fast enough.

Using a Dura-Lite CAC test kit to check for leakage and doing routine oil samples is the best practice and such a simple procedure to insure long engine life.
You should test your charge air cooler every time you change the oil or perform preventive maintenance on your truck. That way, you know your truck and its systems are always ready to handle whatever jobs are thrown their way.

If the CAC is leaking, consider replacing it with Dura-Lite’s 7-year, million-mile guarantee Evolution® Charge Air Cooler.  Find out more...
