Mustang Convertible Tops Explained

Mustang convertible tops are operated by a hydraulic pump system The hydraulic pump is used to pump fluid to the lift cylinders, raising and lowering the top. Power to the pump is supplied through a switch operated by the driver of the vehicle. The first push-button convertible top system was implemented in 1983 with the release of the Fox body convertible. Since then, Mustang convertible systems have remained largely the same. 

In order to lower the top in your Mustang, you must make sure the car is at a complete stop because the top is unable to be raised or lowered while moving. First, disengage the latches that lock the top to the header panel of the windshield. After you’ve released the latches, roll down your windows to prevent interference or damage when lowering the top. Once the windows are down, press “lower” portion of the convertible top switch. This will activate the pump, lowering the top. When it’s time to raise the roof, make sure the windows are down, press the “raise” portion of the switch, and lock the latches once the top has come to a complete stop.

The most common problems that afflict convertible tops are tearing of the top or the separation of the rear glass from the top. When the glass separates from a stock top or when it breaks, it’s almost impossible to prevent the top from leaking, which can lead to a moldy Mustang. Fortunately, there are many quality parts available that can get your Mustang sealed up and back on the road. Replacement tops can be purchased with or without glass installed, so you can save some money if your glass is still in good shape. That being said, it is a good idea to purchase a top with the glass pre-installed. Getting the glass properly installed and sealed up can be difficult, so pre-installed glass and can prevent some headaches. Convertible top installation should almost always be performed by an experienced professional since it can be tricky to get the top installed correctly. It is also incredibly time-consuming, so having a pro do it for you can save you a significant amount of time and hassle. 

Aging convertible top systems also experience lift cylinder and lift pump failures. After years of service, the hydraulic components eventually wear out and fail. These components are much easier to install for the average person, so they can usually be replaced quickly and easily at home. When replacing the lift cylinders or pumps, it is important to bleed the system. Bleeding a hydraulic pump purges all the air from the system, preventing overheating and ensures proper operation. Without bleeding, the fluid level could drop too low and ruin your new parts! Once the system is bled and checked for leaks, you should have many more years of trouble free operation.
