Hello, The thermostat ( PN A642 200 16 45) on my 2010, E350 cdi bluemotion is stuck open. This particular PN has what appears to be a solenoid on top of thermostat housing, which I assume holds theromostat closed until desired temp is reached. My local parts shop sold me a replacement OEM part but without solenoid and cannot source identical part. My question, can I run replacement without solenoid. If not can anyone provide source (dealer last option).
Thank you in advance for your thoughts
