Where are the freeze plugs located in a 07 Dodge charger with a 2.7litre engine

the wire end plug AC is there, see that, just follow it to the heater
works on all cars this simple obvious step.
or of confuses ask your local shop tech to show it to you.
or just plug it in and pray PnP

There r freeze plugs. But disconnect bottom hose on engine n let drain..utube can show u bettr

On the side of the engine block and cylinder head There may also be some located on top of the head under the valve cover

iF THE ENGINE IS NOT LEAKING. THEN FREEZE PLUGS ARE NOT A WORRY, IF THEY ARE LEAKING LOOK FOR GREEN COOLANT ON THE SIDE OF THE ENGINE ABOVE THE OILPAN AND UNDER THE MANIFOLD.

my purge valve solenoid on my 2007 dodge magnum is under the hood on the back left hand side...gonna replace it when the part comes in tomorrow because after all my research that should resolve the issue.

P0660 DODGE Description

The Intake Manifold Tuning Valve (IMTV) system is monitored for failure during continuous, key ON engine OFF or key ON engine running self-test. The test fails when the signal on the monitor pin is more or less than an the expected calibrated range

Symptoms- Engine Light ON (or Service Engine Soon Warning Light) Possible Causes- IMTV signal circuit open, shorted to power or ground.
- Damaged IMTV actuator.
- Damaged ECM.
When is the code detected?Dual plane intake system-Control solenoid failure

My 07 dodge charger brake light,abs, esp, bas light on an check engine light on an the hand show u how fast u going don’t work I took it to auto zone an they run a check on it an the code showed up u1120 an u1121i replace the rear brake sensors an drove it around the corner but the lights are still on.

Both sides, front, and back of the block. It's not a job to be taken lightly. If by any chance you can happen to see one. Look for an indentation on the engine block under the exhaust manifold. Looks king of like the inside of a baby food jar lid. Since you have a transverse (sideways) engine. Front and back are relative, meaning...the front of the engine is on the passenger's side, and the back of the engine (driver's side) is mated to the transmission. If you are able to locate the plug(s) that is/are leaking and remove it/them. They can be replaced with expansion freeze plugs that go in the hole and tighten with a wrench. The function of the freeze plug is to release pressure to from freezing. If an improper coolant mixture is in the engine and the coolant (antifreeze) happens to freeze. The plug pops out to diminish the chances of the engine block cracking. They are however prone to rust under certain circumstances.

I hope this helped.

Did you replace the cables, and the PCV valve? or check if the coils are leaking power, and if the check engine lights on. ok

In my experience with the 2.7L engine, the spark plugs are located on the top of the engine below the individual ignition coils. The coils are placed between the intake manifold and the valve covers, 3 per side. The coils are held in with "torx" screws. Simply remove the screws, and disconnect the connectors to remove the coils. The spark plugs will be underneath. Be sure to properly gap the spark plugs for maximum life and emissions compliance. Also, an improperly gapped plug can shorten the life of the coil packs.
Hope this helps!
