According to the Owner's Manual, the 2001 Cadillac Deville holds 7.5 quarts (or 7.1 L) with a filter change.
Depending what make it is; Deville has a 4.9 (V8). Deville Concours 4.6 (V8)Northstar engine. Eldorado has the 4.6 (V8) Northstar engine. Fleetwood 5.7 (V8) Seville 4.6 (V8) Northstar engine.
you dont. a cadillac tech does
A 97 Deville would be equipped with the Northstar V8 engine, therefore, it has 8 spark plugs.
The 4.6 liter Northstar engine takes 7&1/2 quarts with a filter change!
The Northstar engine is factory spec'ed for Dex-Cool or equivalent. Do not use standard "green" antifreeze.
If it is the Northstar engine which I believe it is, it is inside the motor under the intake manifold.
waterpump or radiator hose
No it does not. The only engine in the 1988 Cadillac De Ville was the 4.5 Digital fuel injected engine. The 4.5 engine is a 2 valve per cylinder overhead valve (not overhead cam) engine. It was a good engine but not in the power category as the Northstar.
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.
Next to the winshill wiper fluid
there is one before and one after the catalytic converter.
Speed is computer controlled and there is no governor that you can remove.
The 1998 most likely has a Northstar engine. On this engine the starter is under the intake, and the intake has to come off for replacement.
Cadillac Northstar is a a type of motor car engine produced by the American compant Cadillac. Northstar engines can be found in Cadillac garages and via online websites.
Well, if it is a Deville with the Northstar 4.6L engine, the manual calls for 7.5 quarts with filter.
They are located to the right and slightly above the oil filter looking at the front of the engeine
The 2000 General Motors/Cadillac Deville came equipped in the 4.6L Northstar engine. Removing the main belt will require depressing the tensioner to free it. The new belt can then be routed across the accessory drive pulleys. The OE AC Delco belts for this application are 6K815 and 3K243.
Cadillacs and the northstar engine are notorious for squeaky belts. if i were you i would not do it yourself. take it to a dealer mechanic.
how can you tell if you need a radiator in a 99 cadillac northstar engine
double platinum Bosch gapped at .55 - pretty standard stuff!
How to change the ect on the northstar engine
The 2005 Cadillac SRX has a V6 engine.
