I told the mack salesman about it and he told me they didn't have the one for my engine, they only had the 16psi, and he said that I needed the 10psi but he was not sure if there is one for this Truck. Is it the same one for all of this models?

I have the same problem now with my 1997 ch613, I got an E7 355 and it's pushing coolant to the overflow tank but it's not retrieving it, i notice that when the bottom tank gets full and the fan clutch kicks in, the coolant gets sucked back up to the top tank and that's when it cools normal, but now it's not doing it and it's pushing coolant off the bottom tank cap until the alarm turns on and shut off the truck, it doesn't get hot it's just low on water. I've try almos everything change water filter, change top tank, change most of the main hoses, new gaskets on air compressor, took off water pump and its good, oil cooler is clean, radiator got clean twice now. What else can I do? We did some test to check head gaskets but we didn't find any carbon monoxide . I can run 100 miles before alarm is on.

Hello I have a Mack it is a ch600 1997 and I'm having a problem, some time during the day the rpms will go all the way up, the niddle will go back sometimes but others it'll just stay hi and I have to shut it off. It's doing it more often now. If some one can help me with that I will appreciate.
