How to Change Polaris Ranger 800 Crew Oil & Filter

Step 1. Run the engine for a minute to warm the oil, which makes the oil less viscous and easier to drain.

Step 2. Position a drain pan under the engine, and remove the 6mm Allen drain bolt from beneath the crankcase.

Step 3. Let the old oil drain out, then reinstall the drain bolt and torque it to 16 foot-pounds.

Step 4. Remove the rear seat by pulling it upward to release it, then remove the storage bucket under the left rear seat.

Step 5. Position a rag or shop towel under the oil filter, which is located at the lower left side of the engine, then remove the oil filter using a gear leverage oil filter wrench.

Step 6. Smear a film of oil over the rubber O-ring on the new oil filter (included in the oil change kit) and install the filter. Hand-tighten the new oil filter, then give it an additional half turn using the wrench.

NOTE: Don’t overtighten the oil filter or it’ll be very difficult to remove during the next oil change.

Step 7. Clean the dipstick tube to eliminate debris that might fall onto it when the dipstick is removed. 

Step 8. Use a flexible spout funnel to access the dipstick tube, and fill the engine with 2 quarts of Polaris PS4 engine oil (included in the oil change kit). Reinstall the dipstick.

Step 10. Reinstall the storage bucket and the rear seat. Make sure the two tabs in the back of the seat align with the slots in the frame, and that the seat belt locks are above the seat so it can slide back into place properly.
