Hi, I need to change pressurestat in my Marea 110 JTD, but this device is drawn mounted vertically in ePer, although it was mounted horizontally (connector towards the front of the car). I need to buy a new one, but I'm not sure, that if I used part number found in ePer, it would be the right one - I know about at least two same looking pressurestats. Could someone please pair this device with a Fiat or OEM part number for me or tell me which Fiat model this pressurestat comes from? Unfortunatelly it can't be purchased based on the information engraved on it here in CZ. Thanx a lot.

Magneti Marelli
B837 (This should be compressor model)
283000 (Magneti Marelli model number)
507774000
R134a/12VDC (Coolant / power)
The connector has 5 pins ::.
