Grand Caravan V6-3.3L VIN E Flex Fuel (2007)
Spark Plug: Description and Operation
DESCRIPTION - PLATINUM PLUGS
The V6 engines use platinum resistor spark plugs. They have resistance values of 6,000 to 20,000 ohms when checked with at least a 1000 volt tester.
For spark plug identification and specifications, Refer to the Specifications.
Figure 1 Platinum Pads
Do not use an ohm meter to check the resistance of the spark plugs. This will give an inaccurate reading.
When the spark plug has a single or double platinum tip, the recommended service life for normal driving conditions per schedule A is 100,000 miles
(161 000 km). The spark plugs have a recommended service life of 75,000 miles (121 000 km) for severe driving conditions per schedule B. A thin
platinum pad is welded to both or just the center electrode end(s) as shown in.
