Hi everyone, in need for some guidance/ or help.
I have a 2004 Mack ch613 and I am having a squealing noise from the turbo area under the hood, it only does it under a load when it’s hot. It won’t do it cold! It’s been doing it for a couple months now the motor was just rebuilt with new turbo. I replaced the Intercooler and all the intake boots and I have no intake leaks. I’m thinking it’s exhaust but I’m not sure where to start, and help is much appreciated, I also have a video of the sound it makes.
thanks
