    My Cadillac SLS Seville is a 1998, 4.6 Northstar "Y" motor. I have found a test motor and trans that has never been in a car (part number 6RUS1611377). The seller thinks it's a 1995 or 1996 Northstar 4.6. The seller also clams it will fit in my 1998 SLS Seville. I want to make sure before putting out the money to purshase.

    Ok 3rd time is a charm....Not really sure if someone can answer this....I have a 1998 Seville SLS 4.6 "Y" motor. I have found a motor and trans that were with Cadillac's test lab, 1995 or 1996 (Part number 6RUS161377), the motor has under 50 hours on it's worth taking a gamble on it. What I need to know is if this motor will fit in my 1998 Seville SLS.

If it's the same size cadillac engine and the transmission on it is listed for your car (get the transmission model and check if parts are listed for it for your car at the auto parts store) then it should fit. What you may really need to know is will the electical be compatible with your car. If you still have the old engine you can probably swap out any parts you need but getting everything sinchronized could end up being the real job.

Hi! If i am to ask, I'll pick a 98 seville motor on the junkyard and recondition if which I assure will work. I wont settle for something that havent been tested on a car. I will pay anyway, so I'll pay for a motor that will work. Hope this shed some light. Have a good one!

    Thanks for the additional info. Just found out that it will fit. They are the same and you can use it. If you can ask for a warranty well and good.

The 1998-2004 Cadillac Seville SLS use the 4.6 L LD8 Northstar V8 motor. As long as your replacement motor is the same as your original motor then it will fit perfectly

1999 seville sls gas lid will not open


Check your fuses. If you can't find a bad fuse, it could be a faulty solenoid that opens the door.

There should be a manual release in the trunk near the gas door.

Hello: All Cadillac Devilles had a Northstar starting in 1996. It will not make any difference if it is a SLS (275 HP) or a STS (300 HP)

1998 Seville SLS, 42,000 mi, Limit speed to 90mph.


it mean that one of the electronic load leveling sensor is not reading. that sensor tells the air pump to fill up that air shock or air bag. the sensors maybe reasonable price wise but if the sensor is reading that an air shock is not holding air pressure and an air shock is not cheap.
