To find the correct compression pressure range, you need to:
1. Locate your engine's specifications: Look for a sticker under the hood (often near the radiator), in your owner's manual, or a repair manual specific to your Dakota's year and engine. This will list the correct compression pressure range for your engine.
2. Consider the testing procedure: The way the compression test is performed dramatically impacts the results. Things like engine temperature, throttle position, and battery voltage all play a role. Always follow the instructions in your chosen repair manual.
Without knowing your engine size, any number I provide would be unreliable and potentially misleading. Using an incorrect value could lead to unnecessary repairs or misdiagnosis. Always consult your owner's manual or a reliable repair manual for your specific vehicle.
