How it Works
Remove turbo hoses and clamps.
Install Tester-Kit plugs and clamps. Mount gauge and double check system.
Apply 30 psig of air. Remove air supply and check gauge. See chart (below) for Leak Down Rate Specifications. If leakage occurs beyond these specifications, it is strongly recommended that you replace your existing cooler with a Dura-Lite Evolution® Charge Air Cooler.
Release air. Test is now complete.

What Our Customers Are Saying
I have used Dura-Lite on past trucks. I just installed an Evolution US-CUSDAC-281F CAC on my 379 Peterbilt with a high HP Caterpillar engine. The exhaust gas temperature was lowered compared to the stock CAC. Great fitment, easy install, and very well built product!
Dura-Lite’s unique design holds up against the punishment of the road so well that it’s warrantied for a million miles. That’s a no-brainer. Be sure to test often and always ask for a genuine Dura-Lite Charge Air Cooler.
Product appears to be of much better quality than the OEM cooler I removed.
The OEM coolers just do not last, and when ordering new trucks the option should be available to specify Dura-Lite.
Love the idea of warranty with that many miles, and this charge air cooler is not that much in price compared to other coolers.
Your product is the very best and I’m happy to order a new one, my Dura-Lite was installed 12 years ago and has run well for over 2,000,000 miles!
Thank you Dura-Lite for making quality products that last.
I have been using Dura-Lite coolers for probably about 20 years. I have always been satisfied with the Dura-Lite product and I can’t ever remember having to make a warranty claim..
I have used Dura-Lite charge air coolers in much of our fleet
I like your products; you need to push out more radiators for the same vehicles.
