  Q: How to Maintain and Fix a Drive Belt on Chrysler 300M?

  A:

  You should begin service and repair of the drive belts by unfastening the locking nut on the generator/power steering tensioner pulley, putting the vehicle on a hoist and removing the belt. Slide off each of the two push clips and remove the lower air shield. Turn the tensioner adjusting bolt counterclockwise until the belt can slip off. Begin by unfastening the generator/power steering drive belt, loose the nut that tightens the tensioner pulley and twist the tensioner pulley screw to make the belt easier to remove. It is important to clear the belt pulley grooves of oil, grease and coolants before placing the drive belts. It is important to replace the belts if they become very worn, aren't well connected or have lots of glazes, yet minor ribbed-side cracks are normal. It is important not to use a dressing or restorer on Poly-V belts. Use Special Tool 7198, Belt Tension Gauge, when installing, to ensure the accessory drive belts are properly tight. Put the air conditioning belt around the drive pulleys and tighten the tensioner adjusting bolt until the air conditioning maker's recommendation is met. Lastly, press in the tensioner pulley locking nut to 54 Nm (40 ft. lbs.). After that, install the drive belt and adjust it to the required tightness. After that, put the generator/power steering belt on, tighten the adjusting bolt until the right tension is reached, fit the lower air shield with the push clips, lower the car and tighten the tensioner pulley locking nut to 54 Nm (40 ft. lbs.). Use the belt tension gauge for belts of any age and follow the chart in the manual for 2.7/3.5L engines.

  Q: How to Remove and Install a Drive Belt for the Generator/Power Steering on Chrysler 300M?

  A:

  The front timing belt cover on the Poly-V generator/power steering belt has an adjustable tensioner pulley. To remove the belt from the serpentine, loosen the nut on the tensioner pulley, lift the vehicle on a hoist, pop out the two clips holding the lower air shield and pull out the air shield. After that, turn the tensioner adjusting bolt counterclockwise so you can take off the belt. Before you install the drive belt, remove all debris and wipe the groove on the belt pulley clean of oil, grease and coolants. Guitars with serious wear, split cords or heavy glazing of the top need the belt replaced, although a few little cracks from the reverse bending are normal. Never put any dressing or restorer on Poly-V belts. You should use Special Tool 7198, Belt Tension Gauge, to achieve proper tension when installing accessory drive belts. Install the generator/power steering belt first, then go on and tighten the adjusting bolt until it meets the right tension requirements. Reattach the lower air shield and the push clips holding it, bring the car down and complete by tightening the tensioner pulley locking nut at 54 Nm (40 ft. lbs.).
