The Chrysler Sebring convertible is a popular choice for drivers who enjoy the thrill of open-air driving. However, over time, the hydraulic motor that powers the convertible top may fail due to wear and tear, fluid leaks, or electrical issues. Replacing the hydraulic motor can seem like a daunting task, but with the right tools, materials, and guidance, you can complete this repair yourself and save on costly mechanic fees. This comprehensive guide will walk you through every step of the process.
Before diving into the replacement process, make sure you have all the necessary tools and materials. Having everything on hand will save time and ensure a smoother repair process.
- 19mm socket wrench – For removing bolts.
- 18mm socket with extension – For accessing hard-to-reach areas.
- Flat bar or crowbar – To pry off seat components.
- Allen wrench (5/32 or 4mm) – For loosening insulator plugs.
- Bent-nose needle pliers – To handle small hydraulic lines.
- Screwdrivers (flathead and Phillips) – For general disassembly tasks.
- Replacement hydraulic motor – Ensure it is compatible with your Chrysler Sebring model year.
- Hydraulic fluid – Use Dexron II automatic transmission fluid or Mopar Fluid 5127381AB as specified by Chrysler.
- Zip ties – To secure loose wires or hoses during reassembly.
- Container with a spout – For refilling the hydraulic fluid reservoir.
- Shop towels – To clean up any spills or leaks.
Before replacing the motor, it's helpful to understand how the hydraulic system works. The convertible top on your Chrysler Sebring relies on a pump-driven hydraulic system to raise and lower the roof. This system includes:
1. Hydraulic Motor (Pump): Powers the movement of hydraulic fluid to lift cylinders.
2. Hydraulic Lines: Transport fluid from the pump to the cylinders.
3. Lift Cylinders: Convert hydraulic pressure into mechanical motion to move the top.
4. Reservoir: Stores hydraulic fluid for operation.
When any component in this system fails—especially the motor—the convertible top may stop functioning properly.
1. Start by removing the rear seat bottom:
- Use a flat bar or crowbar to gently pry up the front edge of the seat bottom where it clips into retainers.
- Once loose, lift and slide out the seat bottom.
2. Next, remove the rear seatback:
- Locate the center loop and side tabs securing it in place.
- Use an Allen wrench to release these attachment points, then carefully lift out the seatback.
- Once you've removed both sections of the rear seat, you'll see a heavy rubber mat covering the pump assembly. Fold or tape this mat upward to expose the hydraulic motor and related components.
1. Identify all wiring harnesses connected to the hydraulic motor.
2. Carefully unplug these connections by pressing down on their release tabs and pulling gently.
3. Inspect each connector for corrosion or damage before proceeding.
1. Locate the two main hydraulic lines attached to your motor (usually labeled "up" and "down").
2. Use bent-nose needle pliers to loosen and detach these lines from their fittings.
3. Be prepared for some fluid leakage; position a container or shop towels beneath to catch any spills.
1. The motor is secured with four insulator plugs that act as vibration dampeners:
- Use an Allen wrench to unscrew these plugs one at a time.
- Keep these plugs handy for reuse if they are in good condition.
2. Gently lift out the old motor from its mounting bracket.
1. Position your new hydraulic motor in place within its mounting bracket.
2. Secure it using either new insulator plugs (if provided) or reuse your old ones if they are undamaged.
3. Reconnect all electrical wiring harnesses securely.
1. Attach each hydraulic line to its corresponding fitting on the new motor:
- Ensure a tight connection to prevent leaks during operation.
- Double-check that lines are not kinked or twisted.
2. Use zip ties to secure any loose hoses or wires out of harm's way.
Refilling hydraulic fluid is a critical step in ensuring proper operation of your convertible top:
1. Locate the reservoir cap on your new motor and remove it.
2. Using a container with a spout, slowly pour in Dexron II automatic transmission fluid or Mopar Fluid 5127381AB until it reaches the recommended level.
3. Operate your convertible top several times to circulate fluid through the system:
- Watch for air bubbles escaping from the reservoir; this indicates trapped air is being purged from hydraulic lines.
4. Recheck fluid levels after cycling; add more if necessary until no bubbles remain.
1. Fold down or reposition the rubber mat over your pump assembly area.
2. Reinstall both sections of your rear seat:
- Attach seatback first by aligning its tabs with their mounting points and securing them with an Allen wrench.
- Slide rear seat bottom into place and press down firmly until it clicks into retainers.
3. Perform a final inspection of your work area for loose tools or debris before closing up.
If your convertible top doesn't operate smoothly after replacing its motor:
- Check for air bubbles in hydraulic lines; repeat bleeding process if needed.
- Inspect all connections for tightness; loose fittings may cause leaks or reduced pressure.
- Verify electrical connections are secure; damaged wires can prevent proper operation.
To avoid future issues with your Chrysler Sebring's convertible top:
1. Inspect hydraulic lines regularly for signs of wear or leaks.
2. Keep fluid levels topped off according to manufacturer recommendations.
3. Operate your convertible top periodically during storage months to keep components lubricated and functional.
Replacing a convertible top hydraulic motor on a Chrysler Sebring may seem intimidating at first glance, but by following this detailed guide, you can complete this repair confidently and efficiently. Regular maintenance of your vehicle's hydraulic system will ensure years of trouble-free operation, allowing you to enjoy every sunny drive with ease.
A faulty hydraulic motor may cause slow operation of your convertible top or prevent it from moving altogether. You might also hear unusual noises when attempting to operate it, such as grinding or whining sounds.
Use Dexron II automatic transmission fluid or Mopar Fluid 5127381AB as recommended by Chrysler for optimal performance and longevity of your system.
Yes, you can manually operate your convertible top by applying force to move it into position; however, this requires significant effort due to resistance from lift cylinders filled with fluid.
Hydraulic fluid should be checked every few years or whenever you notice slow operation of your convertible top. Low fluid levels can indicate leaks that need addressing promptly.
Leaks are often caused by worn seals in hoses or cylinders, which allow fluid to escape and air to enter, reducing system efficiency over time.
