				Hi
 
 I know this has been asked probably a zillion times, but looking through the forum I'm seeing that the number recommended for the CTS is 90541937, however this number doesn't show up on the vauxhall parts catalog I'm looking in, if I filter on my VIN for either the 2.6 or 3.2 the number listed is: 90510493
 
 Can't see that number anywhere in the forum. I've got a 90541937 here, a black one believing it would fit either engine. Just want to check if there is more to this or is that one ok after all?
 
 
 Thanks

				Which coolant temp sensor?
 
 I can think of four on any Omega with aircon...
- 
				Also it is plugged into the correct loom?
 
 The purge valve has the same plug but runs a 12v reference not 5v.
 
 Presuming that you mean the ecu temp sensor on the coolant bridge rather than the thermos witches on the radiator.

 Aye, its the CTS on the coolant bridge.

 Ecu or gauge?

 The ECU one.

 The CTS body is black. This is on the elite. Prety certain it was the same on the 2.6

				Blue rings a bell...  :-\
