Question 1
what makes an engine a Hemi?...  

Answers
1)   The term 'hemi' was coined in the 60's when Dodge designed a new head for their engines utilizing hemispheric combustion chambers. It raised efficiency of the burning process, which raised horsepower. The name stuck to this day. - Pancakes

3)   I read this description many years ago. The heads of the engine where the pistons approach are manufactured in what was described as a hemispherical configuration which allowed for more compression, even firing, hence more power. The ignition would would actually ignite the Fuel with a spherical action to aid in power distribution and exhaust. - tech10

4)   Simply put the heads where the air and fuel go in the combustion chamber, it looks like a half round ball - rick b

5)   The shape of the upper combustion chamber,its hemispherical with the location of the spark plug on top in the center. It provides an up to down even, balanced flame front expansion. It requires proper fuel management in these leaner engines. VVT and other advances in valve timing make these changes possible. - Joseph

Question 3
Can I leave the back door open for extended amounts of time without it running down my battery?...  I own a 2007 PT Cruiser.

Answers
1)   how long?
20 minutes an hour should be ok
overnight might run down the battery - Dave87gn

2)   Yes, i left it for hours and still got the battery, hope this helps - Faisal

3)   It depends on how good your battery is. On a fully charged battery an hour with any lamp on will not damage you requirements for the starter. If you drive the car , and are constantly refilling a good battery with a healthy charging system a half hour will not hurt you. Have fun with your car and buy yourself a battery charger just in case. - Joseph

4)   If you have an interior "light defeat", which turns out the interior lights when a door is opened for an extended period of time, use that to turn out the light.

If you have one it will be on the headlight switch and rotate is either all the way clockwise or all the way counterclockwise, can never remember which way. One way will turn on the interior light(s) regardless of door position and the other way will turn out the lights if the switch has that capability. - Don't know everything !

How to install billet grille on a Chrysler Concorde limited 2003?...  

Answers
1)   Follow the directions that came with it. - Mark B

2)   We just installed the billet grill on my Sebring and it was a learn as you go process.
Don't believe the no tools required claim,or think you just snap it over your existing grill, you will need tools.

We ended up taking the whole bumper off. there were a couple screws and we removed the entire grill and replaced it with the billet grill, it looks great.

The grills sell on E-Bay for around $100
if you are unsure just have it professionally done. - kinz
