I should know, I was making and selling these for close to 10 years.
But they have one big flaw: they are not resistant to oil.
It’s easily explained. What happens to rubber matting when oil gets onto it, it turns soft.
Same with the seals, then the heat dries the seals out, cause them to crack and then they leak too.
This is a common practice where they take your old CAC and either sell you one with a new core or weld a core into your existing end tanks.
Either way, what you have is old end tanks with a new core.
Now depending on the core depends on the life/ problems you can expect.
One thing is certain though, with old end tanks you have heat/flexing stress in these that can cause brackets, spouts and even the tanks to fail.
New plate and bar CAC’s
These coolers are gaining momentum now as they use the same core design as high pressure CAC’s and oil coolers that you see in industrial applications.
In industrial applications they can be running up to 300psi.
That’s over 10 times the pressure in a normal prime mover.
Yes they are slightly heavier however their strength against heat and cracking is above all the others available.
Should you have a turbo failure or a leaking seal the oil can be cleaned out quickly and doesn’t mean a new cooler is needed along with the turbo etc you already have to replace.
A-one charge air coolers are able to test your CAC in your truck, has the ability servicing your existing CAC or supply you a new CAC from their full stock of all new plate and bar CAC’s available around the country.
is hard to tell if yours is leaking or not as it won’t leave oil or water stain on the ground when you pull up.

GET IT CHECKED: It’s hard to tell if your charge air cooler is leaking or not because it doesn’t leave a stain.
