What is the firing order of the Hemi engine?
What is the firing order of the Hemi engine?
The Hemi engine cylinders are numbered in the following firing order- 1, 8, 4, 3, 6, 5, 7, and 2. When the MDS is activated, it disables every 2 nd cylinder. So, 1, 4, 6, and 7 cylinders are deactivated accordingly to achieve rotational balance.
What are the updates to the 5.7 Hemi engine?
A few notable updates to the 5.7 HEMI include: Variable Camshaft Timing is Chryslers terminology for variable valve timing. This allows the engine to advance or retard cam timing for optimal performance at all RPM’s. The 5.7 HEMI cylinder head is also re-worked to improve flow. Intake manifolds receive an update, too.
Is the tick on the 345 Hemi engine normal?
Ticking on the 345 HEMI is an interesting discussion for a few reasons. Some claim the ticking is normal and doesn’t affect longevity or performance. However, engine ticks have led to other 5.7L HEMI owners replacing their entire engine. What are the potential common causes of 5.7 HEMI ticking?
Why does my Hemi engine turn off 4 cylinders?
Multiple Displacement System (MDS) is also known as “Eco Mode” by many drivers or car owners. This system turns off 4 cylinders on the Hemi engine. The aim of this operation is to ensure you use less gas while driving under light loads.

Can a 5.7 Hemi engine crank no start?
If the voltage returns to 5V while the coolant temp sensor is disconnected then you know the sensor is shorted. Try disconnecting the coolant temp sensor and cranking the engine to see if you have spark at one of the coils. For your question about the extra ground, yes, it is always good to have a soild, reliable ground.
When did the first hemi engine come out?
The original hemispherical combustion chamber engine design was introduced with the FirePower name for 1951 model-year Chrysler and was rated at 180 hp. The history of the Hemi is filled with plenty of memorable highlights such as Richard Petty’s dominance at the 1964 Daytona 500 where he lapped the field.
