Had to replace my thermostat 2014 CTD, kept throwing a code related to low coolant temperature. Got new part at dealer about $100. It's located on side of engine under the throttle body area on my 2.0L diesel. Wasn't that difficult to replace.Not sure but I think the thermostat housing is cracked. Car has 39000 miles. I am the original owner. Is this a common issue? Anybody replaced theirs if so. Where is it located and how difficult replacing it.
