Coolent temp sensor with 2 posts HELP!!
 

So I want to replace my coolent temp sensor, but I can't find the one I need !!!! check on here and other site everyone has the 4 post one but know one sells the two post one that I need, for my 400E:confused:

Sensor
 

A0055421017 or optional A0055422617

Not the right part.

Yes it is.

That is the coolant temp sensor for the 400E that is on the intake that controls signal to the relay for aux fans. I have a 400E and tjts1 is right.

Thanks I coul not find it anywhere!!!!!!!!!!!

Stupid me for using EPC and having spent the last 10 year selling and installing parts for Mercedes in addition to owning a 400E witch i replaced that sensor two weeks ago using the parts number i gave, That must be why my temp meter is working.

I am not trying to be rude when I said it was the right part but the 2 wire sensor he is asking about, that is the correct one. There is also a 4 prong sensor for temp. The 2 prong controls the Aux fans not the gage. You are correct in your statement but he is correct with his statement also.

There are 3 sensors on the manafold a two prong for fans, (the one I need) what are the 4 prong And one prong for ???

temperature gauge.

AHHHHHH Thanks

So got a new gauge sensor, coolent temp sensor, and res cap just installed them took it for a ride and let it idol parked for a while temp got to the middle of the 100-120 and the fans kicked in successsssssss!!!!!!!!!! Thanks for the help
