1995 Ford Aerostar Replace Coolant
In 1986, Ford followed Chrysler's lead and released a minivan, known as the Aerostar. This van was far different than its Chrysler counterpart, the most notable difference being that the Aerostar was rear-wheel-drive. The 1995 Aerostar came standard with a 135-horsepower, 3.0-liter V-6 engine and had an optional 155-horsepower, 4.0-liter V-6 available. Ford recommends checking the strength of the coolant mixture every 15,000 miles, and replacing the coolant as needed. Automotive professionals recommend replacing the coolant any time the vehicle has overheated, as excessive temperature may negatively impact the coolant's rust inhibitors.
 Tools Used
|3 gallons 50-50 premixed Ford Premium Cooling System Fluid (or equivalent)|
 Procedures to Replace Coolant
- Allow the Aerostar's engine to cool and remove the radiator cap. Raise the front of the van and slide jack stand beneath the frame rails. Lower the Aerostar onto the jack stands.
- Crawl under the van and place a drain pan under the radiator petcock -- drain plug -- and remove the petcock by hand. If necessary, use a pair of slip-joint pliers to loosen the petcock.
- Allow all of the coolant to flow from the radiator and into the drain pan, and tighten the petcock.
- Slide the drain pan under the lower radiator hose and loosen the hose clamp connecting the lower radiator hose to the radiator, using a Phillips screwdriver. Pull the lower radiator hose from the radiator and allow the fluid to drain into the drain pan. This removes almost all of the fluid from the engine block.
- Reattach the radiator hose and tighten the hose clamp.
- Raise the Aerostar from the jack stands, using a floor jack, and remove the jack stands. Lower the Ford to the ground.
- Fill the radiator with 50-50 premixed coolant to the base of the radiator filler neck. Wait about two minutes to allow air to displace in the cooling system and top off the coolant, if needed.
- Install the radiator cap and tighten it. Loosen the cap to its first stop, known as the pressure relief position. Fill the coolant overflow bottle to the "Full Cold" mark, with 50-50 premixed coolant.
- Turn the temperature and fan setting on the heater to their maximum. Start the Aerostar's engine and hold the rpm at approximately 2,000 for three to four minutes.
- Wrap your hand with a clean shop cloth and remove the radiator cap. Since the cap was in the "pressure relief" position, there will not be pressure built up in the cooling system.
- Fill the radiator to the base of the filler neck with 50-50 premixed coolant. Reinstall the radiator cap and tighten it. Add coolant to the overflow bottle until it reaches the "Full Hot" mark. In total, the Aerostar's cooling system holds 2.95 gallons of coolant.
- Pour the old antifreeze from the drain pan into the empty coolant bottles. Seal these bottles and take them to a used automotive fluid recycling center. Many auto parts stores recycle these fluids free of charge.
 Tips & Warnings
- Automotive engine coolant is highly toxic, so keep it away from animals and children.
