Polaris Ranger 700 Xp Common Problems

The Polaris Ranger 700 XP: a workhorse, a trail blazer, and a valuable asset for anyone needing a reliable UTV. But like any machine, the Ranger 700 XP isn't immune to its share of problems. Knowing the common issues, how to diagnose them, and, more importantly, how to address them, can save you time, money, and a whole lot of frustration out on the trail or around the property.

The 700 XP: A Background Check

Before diving into the nitty-gritty, let's quickly recap what made the Ranger 700 XP so popular. Released in the mid-2000s, it was known for its robust engine, decent payload capacity, and overall durability. It quickly became a favorite among ranchers, hunters, and off-road enthusiasts alike. However, its age also means that many of these machines are now showing signs of wear and tear. Understanding the typical trouble spots is key to keeping your Ranger running strong for years to come.

Starting Troubles: When the Engine Refuses to Roar

One of the most frustrating problems with any vehicle is a no-start condition. The Ranger 700 XP is no exception. Several factors can contribute to this issue:

Battery Blues: A weak or dead battery is the most common culprit. Cold weather can exacerbate the problem, as can leaving the vehicle sitting for extended periods. Solution: Check the battery voltage with a multimeter. A fully charged 12-volt battery should read around 12.6 volts. If it's low, try charging it. If it won't hold a charge, it's time for a replacement. Clean the battery terminals to ensure good contact.
Fuel System Foibles: The fuel system is another potential source of starting problems. This could be anything from old, stale fuel to a clogged fuel filter or a faulty fuel pump. Solution: Start by checking the fuel. If it smells stale or looks discolored, drain the tank and refill with fresh fuel. Replace the fuel filter. If the problem persists, check the fuel pump. You can usually hear it prime when you turn the key. If you don't hear it, it may be faulty.
Spark Plug Snafus: A fouled or damaged spark plug can prevent the engine from firing. Solution: Remove the spark plug and inspect it. Look for signs of fouling (carbon buildup), damage, or excessive wear. If the plug is in poor condition, replace it. Ensure the spark plug gap is correct according to the manufacturer's specifications.
Crankshaft Position Sensor (CPS) Issues: The CPS tells the ECU (Engine Control Unit) the position of the crankshaft, which is crucial for timing and ignition. A faulty CPS can prevent the engine from starting. Solution: Diagnosing a CPS issue often requires a multimeter and some basic electrical knowledge. You can check the sensor's resistance. Consult your Ranger 700 XP service manual for the correct resistance values.

Overheating: When Things Get Too Hot to Handle

Overheating is another common issue that can plague the Ranger 700 XP. It's crucial to address overheating quickly, as it can lead to serious engine damage.

Coolant Conundrums: Low coolant levels are a primary cause of overheating. Leaks in the cooling system can also contribute to this problem. Solution: Check the coolant level in the radiator and overflow tank. Top off as needed. Inspect the hoses, radiator, and water pump for leaks. Replace any damaged components.
Radiator Restrictions: A clogged radiator can restrict coolant flow, leading to overheating. Mud, debris, and even insects can accumulate in the radiator fins. Solution: Clean the radiator fins with a soft brush and a garden hose. Be careful not to damage the fins.
Thermostat Troubles: The thermostat regulates coolant flow to the engine. A stuck or faulty thermostat can prevent the engine from cooling properly. Solution: Remove the thermostat and test it in a pot of hot water. It should open at the specified temperature. If it doesn't, replace it.
Water Pump Woes: The water pump circulates coolant throughout the engine. A faulty water pump can't circulate coolant effectively, leading to overheating. Solution: Check the water pump for leaks or unusual noises. If you suspect a problem, remove the water pump and inspect it. Look for signs of damage or wear.

Drivetrain Debacles: When the Wheels Won't Turn

The drivetrain is responsible for transferring power from the engine to the wheels. Problems in the drivetrain can manifest as loss of power, strange noises, or even complete immobility.

Belt Breakdown: The CVT (Continuously Variable Transmission) belt is a critical component of the Ranger 700 XP's drivetrain. A worn, cracked, or broken belt can cause loss of power or prevent the vehicle from moving. Solution: Inspect the CVT belt regularly. Look for signs of wear, cracks, or fraying. Replace the belt if it's in poor condition. Ensure the belt tension is correct.
Clutch Catastrophes: The clutch system engages and disengages the engine from the transmission. Problems with the clutch can cause slipping, jerking, or difficulty shifting. Solution: Inspect the clutch components for wear or damage. Clean the clutch faces. If the clutch is slipping, you may need to replace the clutch plates or weights.
Differential Dilemmas: The differentials distribute power to the wheels. Problems with the differentials can cause noises, vibrations, or loss of traction. Solution: Check the differential fluid level. Top off as needed. Inspect the differentials for leaks. If you hear unusual noises coming from the differentials, you may need to have them inspected by a qualified mechanic.
Axle Afflictions: The axles transfer power from the differentials to the wheels. Damaged or broken axles can prevent the vehicle from moving. Solution: Inspect the axles for damage, such as cracks or bends. Check the CV boots for tears. Replace any damaged axles or CV boots.

Suspension Setbacks: When the Ride Gets Rough

The suspension system provides a comfortable ride and helps maintain traction. Problems with the suspension can lead to a rough ride, poor handling, and premature tire wear.

Shock Absorber Shortcomings: Worn or damaged shock absorbers can reduce the effectiveness of the suspension. Solution: Inspect the shock absorbers for leaks or damage. If the shock absorbers are leaking, they need to be replaced.
Bushing Breakdown: Worn or damaged bushings can cause play in the suspension components. Solution: Inspect the bushings for wear or damage. Replace any worn or damaged bushings.
Ball Joint Blunders: Worn or damaged ball joints can cause loose steering and poor handling. Solution: Inspect the ball joints for play. If the ball joints are loose, they need to be replaced.

Electrical Enigmas: When the Lights Go Out

Electrical problems can be frustrating to diagnose and repair. However, a systematic approach can often lead to a solution.

Fuse Fiascos: Blown fuses are a common cause of electrical problems. Solution: Check the fuses in the fuse box. Replace any blown fuses with the correct amperage.
Wiring Woes: Damaged or corroded wiring can cause electrical problems. Solution: Inspect the wiring harness for damage or corrosion. Repair any damaged wiring.
Switch Snafus: Faulty switches can prevent electrical components from working. Solution: Test the switches with a multimeter. Replace any faulty switches.
ECU Errors: Although less common, ECU (Engine Control Unit) failures can occur. This is often a last resort diagnosis, and usually requires professional diagnostic tools. Solution: Consult a qualified mechanic to diagnose and repair ECU problems.

Frequently Asked Questions

Why is my Ranger 700 XP backfiring? Backfiring can be caused by a lean fuel mixture, exhaust leaks, or timing issues. Check for vacuum leaks, adjust the carburetor (if applicable), or inspect the exhaust system.
Why is my Ranger 700 XP losing power going uphill? This could be due to a worn CVT belt, low fuel pressure, or a clogged air filter. Inspect the CVT belt, check the fuel pump, and replace the air filter.
How often should I change the oil in my Ranger 700 XP? Refer to your owner's manual, but typically, you should change the oil every 25 hours of use or every six months, whichever comes first.
Why is my Ranger 700 XP smoking? Smoke can indicate various issues, such as burning oil (blue smoke), burning coolant (white smoke), or a rich fuel mixture (black smoke). Diagnose the color and smell of the smoke to pinpoint the problem.
My Ranger 700 XP is hard to shift. What could be the cause? This could be due to a worn clutch, damaged shift linkage, or low transmission fluid. Inspect the clutch, linkage, and fluid level.
