2008 GL450 - Code P0128
I have an 08 GL450 with error code "P0128 - coolant temp below thermostat regular temp".
From some other posts I gather the thermostat is stuck open and I need to replace it. Is this correct and does anyone have a diagram showing the location of the thermostat and procedure? Is this an easy replace or should I take it to the shop? I'm unsure if I can get to it.
Thanks!
