The torque specification for the spark plugs on a Dodge Caliber is 27 Nm (20 ft. lbs.). It is important to tighten the spark plugs to the specified torque to avoid over-tightening, which can cause distortion and damage to the cylinder head. To ensure proper installation, start by hand-threading the spark plug into the cylinder head to avoid cross-threading, and then use a torque wrench to tighten it to the specified torque.

What is the torque on spark plugs for a 2007 Dodge Caliber?
Install your new spark plugs and torque them to 13 +/- 2 ft lbs. Apply a small amount of dielectric grease to the inside of the ignition coil boots.
How tight should spark plugs be tightened?
Screw in the plug until it “seats,” that is, it’s finger tight. Turn the plug an additional ¼ turn. If you’re installing a new plug, screw in the plug until it seats, then turn it an additional 2/3-3/4 turn. This crushes the washer between the plug and the head, forming a tight seal.
What happens if you don’t torque a spark plug?
If you put them in without torquing them correctly (i.e. too loose), they will eventually get blown out of the head taking the threads with them, making for an expensive repair, If they are over-torqued, you’ll either also rip out the threads, or snap the sparkplug in two, which are also very expensive repairs.
Do I have to use a torque wrench for spark plugs?
Applying the right torque when fitting spark plugs is critical to ensuring a secure fastening; DENSO always recommends using a torque wrench to achieve the correct installation torque setting.
What is the torque setting for spark plugs?
Recommended Torque and Tightening Angle
| Thread Size | Applicable Models | Recommended Torque |
|---|---|---|
| M14 Taper seat | All Types | 10-20N・m |
| M14 (Gas) | If the cylinder head material is cast iron | 20N・m |
| M14 (Gas) | If the cylinder head material is aluminum | 17.5N・m |
Do spark plugs have to be screwed in tight?
It is essential to tighten a spark plug to the specified turning angle or torque setting. First, screw in the plug finger tight until the gasket meets the cylinder head. Then seat the plug/gasket with a torque or turning angle wrench as specified in the chart below.
Do you need a torque wrench to install a spark plug?
I have installed spark plugs for 45 years and have never used a torque wrench . A person just has to develop a feel for what is tight . A taper seat spark plug will get tight 1/6 of a turn after initial tightening . This should be good enough .
What is the spark plug gap on a 2007 Dodge Caliber?
Notes: Gap 0.044″.
What is the spark plug gap on a 2008 Dodge Caliber RT?
These spark plugs come with a gap of . 035-. 038 thousandths, however, the recommended gap is . 032, so the gap on these plugs must be checked/reduced before being installed.
Do you really need a torque wrench for spark plugs?
Applying the right torque when fitting spark plugs is critical to ensuring a secure fastening; DENSO always recommends using a torque wrench to achieve the correct installation torque setting.
