Radiator Repair

[cmillsap]

The Radiator/CAC assembly on my bus is the original and was beginning to age out. Some of the copper fins were becoming brittle and cracking and falling to the trough below the radiator. So it was time to replace it. Removing the radiator/CAC assembly provided us with good access to do some other maintenance and upgrades like replacing the original exhaust system with stainless and replacing all the hoses and related parts.

Since we had good access to the driver’s side of the engine compartment, it was a good time to do a thorough inspection of the area. As you can see by the pics, we found an exhaust leak on the manifold and proceeded to replace it.

The radiator is presently being redone. We built new upper and lower tanks for the radiator and installed a new copper core. We also built a new shroud and coated it with bed liner coating. The CAC was cleaned, pressure tested and a small leak was repaired on the bottom flange before it was repainted and made ready to re-assemble. I will post pics of the new radiator/CAC/shroud/fan assembly before we install it. We hope to receive it back from the radiator shop this afternoon.

Below are pics of the work done so far.
