First off I am a little confused, you say the temp went thru the roof but then its running at 170.
The problem is it can be a lot of things. Sticking thermostat; clutch fan malfunction; restriction of air thru the radiator; oil cooler restricted causeing a flash boil int the EGR cooler; blown heads or gaskets.
What is puzzleing is no loss of coolant. I have to wonder if what you heard was the clutch fan actually kicking in an out, they sometimes are real loud especially if they have a chipped or cracked blade.
But then we are back to the temp gauge going nuts.
You really need to have it scanned on live data with a good scanner that can log data while driveing.
