YES
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.
what procedure??
A 97 Deville would be equipped with the Northstar V8 engine, therefore, it has 8 spark plugs.
You still have to remove the transmission on a van to access the rear freeze plugs.
i would check the freeze plugs on both sides of the side of the engine block.
The 2005 Cadillac SRX has a V6 engine.
The Lincoln LS 3.9 liter V8 engine has ( 8 spark plugs ) It depends on the V8 engine , it could take ( 8 spark plugs ) but there are also V8 engines that have two spark plugs per engine cylinder so they take ( 16 spark plugs ) A little more information please ( make , model , engine size )
you remove the "air"(sai) valve
In a word, no. The Northstar engine is a DOHC 4 valve-per-cylinder engine, while the LSx is a traditional pushrod engine. The ports of the northstar are wider to accommodate 2 intake valves, the ports on an LS are narrower and tall feeding a single, large intake valve. The heads on a Northstar are wider and therefore the valley is narrower. The starter on a Northstar is located in the valley. All of these attributes dictate the design of the Northstar intake manifold which, looking similar on top, is very different than an LS manifold on the bottom.
Which engine, V6 or V8?Which engine, V6 or V8?
It has the 4.0 Northstar V8...basically the Cadillac STS Engine with a smaller bore.
