Engine 3126 (420hp)
My temperature gauge reaches normal temp (180) then quickly bouces within 5 degrees. Also noticed the temp cool to 170/160, which leads me to believe the thermostat is bad.
Where is the thermostat located? And is replacing this a simple job? or CAT tech required? Do I need to drain the coolant level first?
