Ford Aerostar Heater Valve

How to Find the Culprits behind Ford Aerostar Heater Valve Problems

The Ford Aerostar has been one of the most favorite family vans in the United States since 1986. With its ample space and excellent features, everyone in the family can have a very comfortable ride. One of the Aerostar's components that provides you real comfort is the air conditioner. The a/c sets the right amount of temperature inside your van. But this won't function properly without the heater valve. This valve is the one responsible in dissipating heat inside the vehicle's cooling system. There are several causes why the heater valve fails. Here are some tips that can help you find out why your valve suddenly stopped working.

When the blower keeps on releasing hot air

It feels uncomfortable when the temperature inside your van is high even if you have already put the blower control to maximum. When this happens, it's possible that your Ford Aerostar heater valve is stuck open. If you want to check its condition, access your heater valve from the dashboard. Look for a device that appears like a small knob. Try to turn it to the left. If you can't move it, then the valve is stuck and must be replaced ASAP.

When the heater doesn't give off hot air

The heater valve works with the radiator and the coolant in dispersing heat from the engine. The heater valve redirects some of the engine heat back into the car. When this component is damaged, your Aerostar's heater won't give off enough heat. In diagnosing this particular problem, you must check the valve for coolant leaks. You need to look closely at the valve and feel the opening of the knob to verify if there's coolant spilling from it. Examine the radiator too. You may experience the same problem if the radiator is severely damaged.

When the blower fails completely

The heater and the cooler in your Aerostar work using the same set of components. That's why it's possible for both devices to stop functioning all at once. In this case, check not just the heater valve but the other components too. Usually, a blown fuse is the major reason why the heater and the a/c don't turn on. You'll know that the fuse is broken once the ceramic part turns black. This fuse must be replaced to bring back the normal operation of your cooling system.

  • Five Tips in Maintaining your Ford Aerostar Heater Valve 04 March 2014

    The Ford Aerostar heater valve is a vital component in your vehicle's cooling system. It is a device that opens and lets the coolant from the engine flow through the radiator or the heater core. It transfers some of the engine heat back into the passenger compartment. Because it entails a very sensitive and crucial operation, the heater valve is prone to wear and damage. It is your job to take care of it to ensure its longevity and efficiency. Here are some maintenance tips for you:

    • Do a regular inspection of your heater valve.
    • You should start with the basic-a regular maintenance check. A careful inspection of the heater valve allows you to see the slightest to the most severe damage. By detecting the problems early, you can think of the best solution to restore the proper functioning of your heater valve. Think of this as a preventive measure to avoid a more costly repair in the future.
    • Stop leaks immediately.
    • Coolant leak is the main reason behind the early deterioration of the heater valve. To stop leaks, you need to buy and install a new heater valve. Don't forget to check the heater hoses for holes and cracks. The leaking won't stop if you change the valve alone. Place fresh gaskets too to further seal the tube openings.
    • Refill your coolant reservoir frequently.
    • Low coolant levels could result to leaks. It damages not just the heater valve but also the radiator. That's why it is very important to always take a peek inside the coolant container and see if there is enough fluid. Never run your car with inadequate coolant to prevent your engine from overheating.
    • Flush out contaminated coolant.
    • A corroded heater valve can contaminate your coolant. If you're replacing your heater valve, then you must change your coolant too. It's possible that your coolant fluid is already full of rust particles and other harmful substances that may clog your newly-installed valve.
    • Remove clogs.
    • The heater valve is not the only component that is prone to clogging. The coolant lines, the heater core, and the radiator can also get damaged because of clogging debris. Clean your heater valve every once in a while to remove impurities. You can also add an anti-corrosion chemical into your coolant to keep the components of the cooling system protected from rust.
