How did we estimate these prices?

Jerry's experts researched and collected data from 2500+ real repair shops in all 50 states in the US, including everything from the total cost of repair services to the hourly labor cost for mechanic labor in each shop. We combined that data with our expert database of hundreds of real repair jobs, thousands of real cars, millions of real car part prices in order to best estimate the cost of each repair service. Our labor cost estimate is calculated by taking the average hourly labor rate for a certified mechanic in the US, times the number of hours it takes on average to complete a repair. We recommend you compare your local shops with Jerry and contact those shops directly to get final pricing for your vehicle.

What parts do I need for my air bleed housing assembly replacement?

You can check your vehicle repair guide or
owner’s manual
for more detailed information. But here is a general overview of the parts you may need:
  • Air bleed housing assembly: This is the primary part you’ll need to replace. Depending on your vehicle, the replacement price can range from $20 to upwards of $100. 
  • Coolant: Before replacing the air bleed housing assembly, you’ll have to drain the engine coolant. When you finish the replacement, you’ll have to refill the system with fresh coolant. A one-gallon container of coolant typically costs between $10 and $30.
Some reputable brands we recommend for reliable air bleed housing assembly are AC Delco, Dorman, and Motorcraft. Meanwhile, some of the the best coolant brands include Prestone, Zerex, and Peak. You can typically find these brands from retailers such as AutoZone, RockAuto, and Advance Auto Parts, both online and in-store. However, like price, recommended brands may also vary depending on your vehicle's specific year, make, and model.
You’ll have to contact your local dealership or authorized parts retailer if you want OEM parts. If you’re fine using aftermarket parts, you can find them at your local auto parts stores—like AutoZone and Advance Auto Parts —or online retailers like RockAuto and Amazon.
Generally, you should opt for original equipment manufacturer (OEM) parts whenever possible. OEM parts are designed specifically to fit your vehicle and come with a manufacturer’s warranty. They tend to be high quality—but they’re also pricey. 
Aftermarket parts, on the other hand, offer a more universal fit and come with a cheaper price tag. 
While OEM parts are typically the best option, aftermarket parts have their place. And you may choose to go with an aftermarket, universal coolant to save some cash—just make sure you check the part number to confirm it works with your car.

How will a mechanic replace my air bleed housing assembly?

If you visit a mechanic for the replacement, these are the general steps they will follow:
  • Allow the engine to cool completely
  • Drain the coolant
  • Locate the air bleed housing assembly—it looks like a black box with a bleeder screw on the top and is typically located near the cooling system’s highest point or the thermostat housing
  • Disconnect any hoses attached to the air bleed housing assembly
  • Remove the assembly’s mounting hardware
  • Remove the old air bleed housing assembly
  • Position the new assembly and install the mounting hardware
  • Replace any hoses that were removed
  • Refill the system with coolant
  • Bleed the cooling system
  • Check for leaks while the engine is running 

What happens if I don’t replace my air bleed housing assembly?

If you don’t replace a faulty air bleed housing assembly, you risk developing the following issues:
  • Coolant airlocks: If the air bleed housing assembly doesn’t work to release air, the engine cooling system may develop pockets of air that block the flow of coolant. This will reduce the cooling system’s efficiency and may lead to reduced performance and engine damage.
  • Engine overheating: If the system develops airlocks, the engine is likely to overheat, resulting in potentially costly damage.
  • Coolant leaks: A faulty air bleed housing assembly can cause coolant leaks.
  • Expensive repairs: If a faulty air bleed housing assembly causes coolant leaks or airlocks, you’re likely to develop severe damage, like blown gaskets or a seized engine. 

What is an air bleed housing assembly?

The air bleed housing assembly is responsible for removing air bubbles trapped in the cooling system. Air bubbles prevent coolant from cycling through the engine block properly, leading to overheating issues. 
The air bleed housing assembly typically sits at the highest point of the cooling system. As air rises, it collects beneath the assembly. Many modern air bleed housing assemblies are designed to purge air passively as it collects beneath the assembly. 
Older systems have bleeder screws mounted on top of the assembly—when you crack the bleeder valve, the air escapes the system, helping maintain proper coolant circulation. 

When should I replace the air bleed housing assembly on my car?

There is no set replacement schedule for the air bleed housing assembly. That means you should only replace yours when it fails. Here are the most common signs of a bad air bleed housing assembly:
  • Engine overheating: If the air bleed housing assembly can’t release air bubbles, the cooling system may be unable to circulate coolant properly to maintain the optimum operating temperature. This can lead to engine overheating issues.
  • Coolant leaks: Coolant leaks are a common sign of a faulty air bleed housing assembly.
  • Strange sounds: If you hear bubbling or gurgling sounds coming from the cooling system, it could be a sign that air is trapped inside.
  • Erratic temperature gauge: If your dashboard temperature gauge is bouncing back and forth, it may be a sign that the air bleed housing assembly is malfunctioning.
  • Coolant discoloration: Air can cause the coolant to appear milky or frothy. If you notice your coolant looks strange, it could be a sign of a bad air bleed housing assembly.
  • Reduced heater performance: Air bubbles in the coolant can affect the heater core’s performance. If you notice that your car’s heater doesn’t work as well as it used to, it may be a sign of a faulty air bleed housing assembly. 
Keep in mind: Many of these issues can point to other problems with the cooling system, like a faulty water pump, cracked radiator hoses, or a low coolant level in the coolant reservoir. 

How often should I replace my air bleed housing assembly?

The air bleed housing assembly doesn’t typically require maintenance or service, and there is no set replacement schedule for it. That means that you’ll only need to replace yours if it malfunctions. 
But due to its location and purpose, it’s unlikely that the average driver will notice the air bleed housing assembly is faulty. Typically, a mechanic will discover the problem during a routine radiator service. Because of that, it’s extremely important to maintain your
cooling system
and keep up with regular maintenance. 

Can I replace my air bleed housing assembly myself?

An air bleed housing replacement can be a solid DIY project—if you have the right know-how and tools. 
This is typically considered a mid-level job, requiring basic mechanical skills and knowledge of automotive cooling systems. Moderately experienced home mechanics should be able to replace the coolant air bleeder with relative ease, but novices may struggle. 
If you’re not confident in your automotive repair skills, you should reach out to a professional mechanic.
