Why Argo Utility Vehicle engine turns over but won't start?
- M
  Michael HernandezAug 18, 2025
  If your Argo Utility Vehicle's engine turns over but won't start, several factors could be at play. Make sure the choke is pulled out if the engine is cold. Check that the fuel tank isn't empty and refill it if needed. A blocked fuel or air filter could also be the culprit, so remove any obstructions or replace the filter. Other potential causes include a carburetor adjustment that's too lean (adjust it as detailed in the engine manufacturer’s manual), defective or fouled spark plugs (clean, re-gap, or replace them), or a problem with the ignition system (have it serviced by a trained mechanic). Insufficient compression could also be the reason, requiring you to take the vehicle to a factory-authorized engine repair outlet.

How to fix inoperative electric starter in Argo Utility Vehicle?
- B
  Brandy WallaceAug 21, 2025
  If the electric starter on your Argo Utility Vehicle is inoperative, start by checking for loose electrical connections and clean and re-tighten them. If that doesn't work, the battery charge might be low or dead, so recharge the battery or replace it if necessary. If the problem persists, the starter motor itself may be faulty, requiring you to return the vehicle to an Argo dealer for servicing.

What to do if Argo Utility Vehicle will not move or turn?
- M
  Misty AdamsAug 23, 2025
  If your Argo Utility Vehicle won't move or turn, first ensure the transmission is properly engaged in gear and not in neutral. If that's not the issue, inspect the drive belt for wear and replace it if it's excessively worn. Other potential causes include a clutch that's not engaging or transmission failure, both of which require servicing by an Argo dealer. Additionally, check if the brakes are functioning correctly by adjusting the caliper or replacing the brake pads if needed. Finally, inspect the idler chain for breakage (repair or replace it) and the idler sprocket weld (have it serviced by an Argo dealer if broken).

Why Argo Utility Vehicle hydraulic brakes are spongy?
- P
  Patrick SilvaAug 26, 2025
  If the hydraulic brakes on your Argo Utility Vehicle feel spongy or there's excessive handlebar travel, it could be due to air in the hydraulic system, which requires an Argo dealer to bleed the brakes. Another possibility is a leak in the system; have an Argo dealer check all fittings, hoses, calipers, and seals for loose connections or leakage and refill as needed. Also, check for loose brakes and adjust or tighten them.

Why Argo Utility Vehicle pulls to the right?
- Z
  Zachary HarrisAug 28, 2025
  If your Argo Utility Vehicle pulls to the right, it could be due to several reasons. Check the tire pressure on both sides: the right tire might be too low, or the left tire might be too high; inflate all tires to the correct pressure. Also, ensure the right brake isn't engaged by holding the handlebar parallel to the dash and adjusting the brake assembly if needed. Finally, inspect the right side drive chain for breakage and repair or replace it if necessary.

Why Argo Utility Vehicle has severe vibration?
- K
  kingjasonAug 31, 2025
  If your Argo Utility Vehicle experiences severe vibration during operation, the engine might be loose on its mounts, requiring service from an Argo dealer. Alternatively, the driver or driven clutch or the engine itself could be defective, also necessitating dealer service. Other potential causes include a bent axle (remove and straighten or replace it), a bent wheel rim (replace it), or a worn or damaged drive belt (replace it; clutch service may also be required).

How to fix Argo Utility Vehicle tire that leaks air?
- T
  Teresa CarlsonSep 2, 2025
  If your Argo Utility Vehicle tire is leaking air, it might be punctured. Remove the tire from the rim and repair the hole with a radial tire patch or install a tube. The tire might not be properly seated on the bead; deflate the tire, carefully push the tire bead off the rim, clean the rim bead area, and re-inflate. If the leak's position isn't obvious, submerge the tire and rim in a water tank to check for escaping air through the rim halves or valve stem, then repair as needed. A defective valve could also be the cause, so replace it if necessary.

What causes handbrake failure in Argo Avenger and Frontier HDi Utility Vehicle?
- Q
  qsmithSep 5, 2025
  For an Argo Avenger or Frontier HDi Utility Vehicle experiencing handbrake failure, worn brake pads or brake cable adjustment could be the cause, requiring you to change the pads or adjust the brake cable. A leaking caliper or brake lines, or air in the system, could also be the reason, necessitating service by an Argo dealer.

Why Argo Utility Vehicle brakes are ineffective?
- E
  estradajulieSep 7, 2025
  If the brakes on your Argo Utility Vehicle are ineffective, the pads may have overheated and glazed, requiring cleaning by an Argo dealer or replacement. Also, if the pads are worn beyond 0.10", they should be replaced. Contamination of the pads with lubricant can also cause ineffectiveness, in such cases, the pads should be cleaned by an Argo dealer or replaced.

How to stop water leaks into lower body of Argo Utility Vehicle?
- J
  Jordan WashingtonSep 10, 2025
  If water leaks into the lower body of your Argo Utility Vehicle, the leak may have developed at the axle bearing flange, requiring replacement of the bearing flange gaskets. Alternatively, the bearing flange seal may be damaged and need replacement. Water may also be leaking around the outer bearing flange bolts; caulk under the 103-81 bolt heads with silicone sealer. If the lower body is cut or punctured, it should be repaired or replaced. Finally, ensure the drain plugs are securely in place.
