Hello, Under the car in the front end,remove bottom cover You will see a bracket approximately in the center behind this bracket is the oil filter adapter, the oil filter is on the passenger side and the oil pressure sending unit is on the opposite side (difficult to see) You will need a oil pressure sending unit socket to remove it after you remove the electrical connector. Hope this helps

98 caddy deville nothstar v8 how to replace heater coil have no heat and I'm loosing water somewhere


the heater core in a 1998 Cadillac is very tricky to replace.
start with getting a pressure test to determine where the exact location of the leak is, it may not be the heater core.
if you do decide to pull the dash apart to change the core make sure the battery is disconnected for at least an hour to allow the airbag system to discharge.

Hello, the sending unit is to the right of the oil filter adapter, it is behind the engine mount bracket, it is hard to see and difficult to access. You will need deep oil pressure sending unit socket. It has a electrical connector.

I have a 1996 Caddy Sedan De Ville with the Northstar engine. Where is the oil sending unit or does it have one?


The oil pressure sending unit is behind the front engine mount. You will need a deep special oil pressure socket to remove and install.It is NOT an easy task. There is no short cut but you might find it easier to remove the oil filter adapter, if you do that you should replace the "O" rings on the adapter. The oil pressure sender is mounted on the filter adapter

Where is the oil filter located on a 93 caddy deville?


Hi, it is located on the drivers side, above the transmission, between the engine block and the exhaust pipe from the front four cylinders. A tip, wait for it to cool down, it's a tight spot, water hoses and wires all in the way, and thats after you remove the air cleaner assembly. Not really that bad when it's cool...
Take care
