It is possible to expect pre-loved Magnums priced at $1000 and over to be in great condition, and some are only utilized for errands at the park or to inspect the animals at the farms.

Certain models have new batteries and come with helmets and the 54-inch snow blade. Some have not been used off-pavement, or on trails.

Incredibly, the majority of units that are listed on auction and trader websites have 2002 versions. Reasons, why owners have sold the quads, are due to the starter not working at all times, the wheels spinning, without the motor spinning without power steering, and the 4×4 being not used as often as it was prior to. 

These issues, however, shouldn’t stop you from buying the 2002 Magnum. Check for any hidden flaws. Also, ask about any modifications that have been made to the vehicle.

How to Change Oil on a Magnum 325 (20 Steps)

a Magnum 325

To assist novice owners (or those who’ve misplaced their manuals for service) Here are the steps for how to do proper oil and filter changes for your vehicle:

1. Put the Polaris Magnum 325 on a smooth surface. The engine should be running for about 3 minutes to warm up and make the oil flow easily. The engine should stop after that.

2. Cleanse the drain plug on the base of the tank, which is on the left-hand side of the vehicle.

3. Before removing your drain plug put the drain pan underneath the tank. Be sure not to let the oil touch your skin, causing severe burns because the oil could be hot.

4. Let the previous motor oil completely drain.

5. To ensure that the sealing surfaces are clear of dirt and free from scratches or burrs, replace the washer that seals the drain plug.

6. Put the drain plug back in and increase the torque up to 14 Ft-lbs (19 Nm).

7. Remove the bolt or clamp and take off the oil hose from the fitting at the lower part of the oil tank.

8. Take the screen fitting off and thoroughly clean it. Apply Loctite(TM) PST 505, or any other similar pipe thread sealant, or PTFE sealing tape to remove threads that are free of oil.

9. Fit the fitting to your screen, and tension it up to 14-17 ft-lbs (19-23 Nm).

10. The same way, connect the oil hose into the screen fitting. Tighten your clamp until it is the tightest setting of 25 in-lb/2.08 Ft-lbs (2.82 Nm).

11. To take off the oil filter to clean it, put a towel under it, then turn it counterclockwise with an oil wrench.

12. Clean the surface of the crankcase filter using a dry and clean cloth.

13. The O-ring should be lubricated with an oil film. Make sure it is still in excellent shape.

14. Then, you can install the new filter and rotate it with your hands until the gasket for the filter touches the surface of sealing. If it does, rotate it by hand for another half turn.

15. Be sure to eliminate the engine oil that is within the crankcase. For this to be done, you must remove the drain plug located on the lower left side of the case.

16. The crankcase drain plug should be torqued up to 14 Ft-lbs (19 Nm) for reinstallation.

17. After the old oil has been gone from both the crankcase and tank remove your dipstick. Add 2 quarters (1.9 Liters) of SAE Polaris Premium 4 synthetic oil.

18. After that, put the gear selector into neutral, and then adjust your parking brake.

19. Switch on the engine and allow it to idle for between one and two minutes in order to allow the new oil to circulate into the system.

20. Stop the engine and look for leaks. If none are found then recheck the oil level on the dipstick, and make sure to add oil as needed. The level of oil should be above the upper line on the dipstick. Then, dispose of the filter that was used and the oil.
