Charge Air Cooler - recore or replace with a different model?

If the radiator repair shop couldn't fix the cracks then JB Weld probably wouldn't work either. They showed me in the soapy water tank where it was leaking, but I still couldn't see the cracks. If I thought JB Weld would work I would try it.

The CAC is rubber mounted at the top, but the bottom is direct mounted.

Here's a company with a very good durability warranty.

The problem with Dura-Lite is they don't want to actually sell anything. You have to sign up for a user account just to see their catalog and user accounts are only for dealers.

Sure, but I have to know what to buy first. I need a catalog to look at all of the designs so I can pick the one that is the right size and easiest to adapt to the piping in my bus.

Dura-Lite is OEM for Prevost don't kid yourself they are not the best around for sure

I found some posts on another forum by a guy who works for a large fleet of Prevost buses. He said the OEM for the CACs in their Prevost buses was Valeo and they were replacing them with Dura-Lite as they failed because the Dura-Lite last a lot longer.

So, what brand charge air coolers do you recommend?

It almost seems like I should retrofit my bus to the cheapest charge air cooler I can find, buy a bunch of them, and just plan to replace it every year. It seems like almost every brand of charge air coolers has people who absolutely love them and just as many people who absolutely hate the same brand.

I don't think any last long,you will never see it but the EGR equipped engines see 50 PSI of boost or more 5 to 7lbs at idle.Prevost is great about telling you manufactured the product used. I checked my manuals for the H-45 and they have 3 different manufactures depending on the serial number so they are looking also .I still do not understand why one will not last
