Dodge Grand Caravan 3.6 Spark Plug Gap, Torque and Interval
Dodge Grand Caravan 3.6 Spark Plug Gap, Torque and Interval with application chart, generation boundaries, verification steps and official manufacturer lookup.
The covered 3.6L Pentastar service specification uses a 0.043-in (1.1-mm) plug gap and 13 lb-ft (17.5 N·m) installation torque. Mopar's 2019 schedule calls for replacement at 100,000 miles.
The covered 3.6L Pentastar service specification uses a 0.043-in (1.1-mm) plug gap and 13 lb-ft (17.5 N·m) installation torque. Mopar's 2019 schedule calls for replacement at 100,000 miles.
The torque row is anchored to the 2011 Grand Caravan 3.6L service information and the interval to the 2019 3.6L guide. Verify the exact approved plug for the VIN before servicing another year. Older 3.3L, 3.8L and 4.0L engines use different plugs and must not inherit this Pentastar row.
Work on a cold engine, remove debris from each plug well and start every plug by hand. The 13-lb-ft value assumes clean, undamaged threads and the specified gasket-seat plug; anti-seize changes friction and can lead to excessive clamp load unless the plug maker explicitly accounts for it. Replace damaged fine-wire plugs rather than aggressively bending the electrodes.

Dodge Grand Caravan Spark Plug Specs
| APPLICATION / ITEM | SPECIFICATION | NOTES |
|---|---|---|
| 3.6L plug gap | 0.043 in | 1.1 mm; approved plug only |
| 3.6L installation torque | 13 lb-ft | 17.5 N·m; cold clean threads |
| 2019 replacement interval | 100,000 mi | 160,000 km; mileage based |
| Plug quantity | 6 | One coil-on-plug unit per cylinder |
| 3.3L / 3.8L / 4.0L | Separate specification | Do not transfer Pentastar values |
Work on a cold engine, remove debris from each plug well and start every plug by hand. The 13-lb-ft value assumes clean, undamaged threads and the specified gasket-seat plug; anti-seize changes friction and can lead to excessive clamp load unless the plug maker explicitly accounts for it. Replace damaged fine-wire plugs rather than aggressively bending the electrodes.
Installation details that protect the aluminum head
Let the engine cool, disconnect each coil carefully and remove loose grit from the plug wells before the plugs come out. Debris entering the cylinder or a plug started at an angle can turn routine maintenance into cylinder-head repair.
Thread each plug in by hand through several complete turns. Apply the final 17.5-N·m value only after the gasket-seat plug is seated normally; the service information warns that excessive torque can stretch the shell and impair heat transfer.
Use the interval as an inspection opportunity
The 2019 maintenance schedule places plug replacement at 100,000 miles and says the interval is mileage based. Earlier replacement may be justified by a confirmed ignition fault, contamination or damage, but a misfire code should still be diagnosed rather than answered with six parts automatically.
Keep removed plugs organized by cylinder. Oil deposits, fuel wetting, cracked porcelain or one unusually eroded electrode can point to a coil, injector, sealing or mixture problem that deserves a separate test.

Dodge Grand Caravan 3.6 Spark Plug Gap, Torque and Interval FAQs
What is the Grand Caravan 3.6L spark-plug gap?+
The covered Pentastar application uses 0.043 in (1.1 mm).
What is the 3.6L spark-plug torque?+
The covered service specification is 13 lb-ft (17.5 N·m).
When does the 2019 guide replace the plugs?+
At 100,000 miles (160,000 km); the schedule says this interval is mileage based.
