First-generation Lincoln LS (1996-2006) firing order
The first and only generation of the LS so far has used two main engine options – the base V6 engine and a higher-trim V8. So, we’ll start with the 3.0-liter which was Ford’s Duratec engine, and make our way through the firing orders and the differences between both these engines.
Lincoln LS 3.0L firing order
The Lincoln LS 3.0L firing order is 1-4-2-5-3-6, and it’s a common firing order for Ford’s Duratec engines of that time. The engine’s layout is also simple since it’s a regular V6 engine with a passenger’s side bank and a driver’s side bank.
In other words, there are passenger’s side cylinders ordered 1, 2, and 3 front to rear, while the driver’s side cylinders are arranged in a 4, 5, and 6 order, also looking at the engine front to rear.
Lincoln LS 3.9L firing order
On the other hand, the V8 version of the LS had Jaguar’s 3.9-liter V8 engine under the hood. So, if you own this one, the Lincoln LS 3.9L firing order is 1-3-7-2-6-5-4-8. The engine’s cylinder placement is also accordingly different from the V6, since this time both cylinder banks have four cylinders.
The first cylinder is on the passenger’s side of this engine, and it’s followed by cylinders 2, 3, and 4 looking at it front to rear. The driver’s side cylinders are laid out in order 5, 6, 7, and 8, also looking from the front-most one toward the rear end of the engine.
