Leaking diaphragm... AGAIN.

There are many causes, but a faulty thermostat or improperly installed thermostat seal can explain your overheating issue. If the thermostat is catching the seal it can hang up or be slow at opening fully or operating correctly.

That temp sensor your referring to is fuel temp not coolant temp. I'm fairly certain Volvo dash's don't have any way to monitor that sensor. If your wondering if the fuel or coolant sensor is operating or reading correctly, get out your Insite set up and monitor those sensors while operating the truck. If you still don't Insite, shame on you... If you do and your not using it, shame on you...

As far as that filter your referring to, that is only on a CM570. I'm not sure what section you found the breakdown for that under your ESN. But you can see on the IFSM breakdown it's not there. If you had a CM570 ESN it would be there and it would've been #25
