It's a good engine, just bad to work on.
The oil capacity of the 4.6L 32 valve Northstar in a 1997 Cadillac is 7.5 quarts.
7qts
it should
assuming it's a Northstar engine. It's in the center of the engine below the intake plenum chamber.
what solenoid are you referring to
Depends on the model
The era gap is huge when considering a 1990 Deville to a 1997, no way is it possible unless you have tons of time to make extreme modifications and LOTS of money.
The flapper valve at the opposite end of the manifold from the throttle body in a 1997 Cadillac Seville with a 4.6L Northstar engine is typically referred to as the "intake manifold runner control valve" or "IMRC valve." This valve helps optimize airflow and enhance engine performance by controlling the intake manifold's runner length based on engine speed and load. It's an important component for improving efficiency and power output.
It is located on the back of the engine (drivers side), on the side of the cylinder head, just above where the trans axle bolts onto the engine. It is brass with a black connector and is very tricky to access.
On a 1997 Cadillac Seville with the Northstar engine, the intake air temperature (IAT) sensor is located in the intake manifold. Specifically, it's typically found near the throttle body, often integrated into the air intake duct or manifold assembly. Accessing it may require removing some engine covers or components for better visibility and reach. Always consult a repair manual for detailed instructions and diagrams.
If it is the same as the '94 SLS Northstar, Its under the intake manifold. Sounds crazy, but true.
There are two variants of the NORTHSTAR. The base Eldorado produces 275 bph and the ETC produces 300.
