The Dura-Lite™ Tester-Kit™ is designed and manufactured to be used to pressure test charge air coolers safely and efficiently. The kit comes complete with everything required to pressure test most charge air coolers. With the Dura-Lite Tester-Kit, testing the charge air cooler will become as automatic as checking the oil and will give you confidence in knowing that an engine is performing at the required level.
The pressure tester comes complete with everything required to test the majority of charge air coolers.
The pressure tester components are made with high quality materials and coatings to help resist corrosion and extend the longevity of the kit.
Charge Air Cooler Test
The Dura-Lite Charge Air Cooler Tester-Kit is a specialized tool designed specifically for testing charge air coolers quickly and accurately. With this tester, you can measure the amount of pressurized air the CAC loses over a designated period of time. This will determine if the CAC is leaking or not. A leaking charge air cooler will rob performance, increase fuel consumption, and increase DPF regeneration cycles.
Adding a charge air cooler test to your regular scheduled maintenance list can help you catch potential issues early on for your customer before they turn into major problems that require expensive repairs. By offering this service, you can identify trucks that have CAC issues and recommend a replacement before it causes loss of power, increased fuel consumption, and potential engine damage.
CAC Pressure Tester
Leaking charge air coolers are one of the most common causes of reduced diesel truck performance. The problem is that the signs of a leaking CAC are not obvious to the operator or even the maintenance technician, until it is so bad that greatly increased fuel consumption is noticed. In a CAC air cools air, so there will be no obvious evidence of a leak, unlike a leaking radiator that leaves a puddle of coolant under your engine.
Data shows that almost half of the charge air coolers aged over two years have leakage in excess of the recommended specification. The result is a lot of excessive fuel being consumed, loss of power and other engine issues being created, reducing the profitability of the owner’s business. For a fleet of trucks, leaking CAC’s can easily cost tens of thousands of dollars in extra fuel bills. The cost of a Dura-Lite CAC pressure tester and the 20-minute test is quickly earned back in improved engine performance and restored fuel economy.
Why do you need a CAC tester? A semi-truck’s turbo system is crucial in helping the truck’s engine to work as efficiently and smoothly as possible. Although charge air coolers are designed and built for hard work under high temperatures, OE, and other aftermarket charge air coolers leak! Unfortunately the leaks only get worse over time, and it is a recommended to do a leak test every time the oil is changed. A well-maintained CAC will help prolong the engine’s life by preventing damage caused by elevated coolant temperatures.
CAC Test Kit
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.
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.
