Replacing The Mercedes Benz Sprinter Heater Control Valve

Sprinter heater control valve, sprinter, heater control valveThe Mercedes Benz Sprinter is everything the brand represents; it is large, comfortable and sophisticated. Essentially, the Sprinter van is a beast when it comes to cargo and delivery. However, if you own an MB Sprinter or you are planning to buy one, especially the 2010 model year and later models, you should be aware that the Sprinter heater control valve in the heating system of your car is likely to malfunction sooner than later.

How does the heater control valve work?

The heating system of your car has the sole responsibility of keeping the interior compartment of your vehicle warm. There are a number of features which make up the heating system one of which is the heater control valve. The heater control valve was designed to regulate the amount of heat in the cabin when the heating system is on.

The valve achieves this purpose by controlling amount of coolant flowing from the engine compartment into the heater core. When the valve closes, the vents remain cool as the coolant cannot get to the heater core. Once the valve opens, the air in the vents warms up. Thus, if your heater valve isn’t functioning properly, then you are in for a cold drive.

What are the signs of a bad heater control valve?

When the heater is on, the temperature of the air in the cabin is regulated by the heater control valve. Thus, if the control valve of the heating system fails, the air in the cabin will most likely not be warm even with the heater on. Because the heater control valve regulates the flow of hot engine coolant into the heater, if the coolant is leaking from somewhere, your heating system will definitely be affected. A coolant leak could result in insufficient coolant to cool the engine and could eventually cause the engine to overheat. If you notice a coolant leak or any one of the signs above, then your heating system is malfunctioning.

What Causes The Heater Control Valve Malfunction?

A malfunctioning heater control valve could be as a result of a coolant leak in the system. If the coolant is leaking, the valve may not be able to fully regulate the temperature of the air in the cabin. Wear and tear is also a possible cause of a malfunctioning valve. A worn out heater control valve is likely to be less responsive and efficient compared a brand new one. If you live in a region where temperatures often drop drastically like during winter, a bad heater control valve could pose more than just a slight inconvenience compared for you.

How Do You Fix A Bad Heater Control Valve?

A bad heater control valve may not affect drivability although the ride could be cold and uncomfortable. However, if you notice a coolant leak, then overheating is only imminent and in that condition, you should definitely avoid driving.

To diagnose a malfunctioning heater control valve, we simply inspect the heating system watching out for the movement of the valve when the temperature selector is adjusted. In some cases, there may be movement in the valve without a corresponding change in temperature and in other cases, the valve may be completely unresponsive. We will also inspect the system for any signs of a leak to determine if the malfunction is as a result of a coolant leak.

Once a diagnosis has been made, we will proceed with repairs. It is imperative to know that heater control valves cannot be repaired – a faulty valve must be removed and replaced. Once the new valve is installed, we also flush the system and refill the coolant. This is particularly necessary especially if the old valve was corroded with rust to prevent contamination of the coolant.

The manufacturers of the Mercedes Benz Sprinter recommend changing the heater valve at least once every 100,000 miles. The heater control valve is part of a closed heating system so it is unlikely that your mechanic will be inspecting it during routine maintenance and inspections. Nevertheless, you can schedule an inspection yourself to ensure that the system is running as it should.

Common Problems with Mercedes Sprinter Vans

common problems with mercedes sprinter vans, mercedes sprinter vans, sprinter vans, sprinter, mercedes-benz sprinterMercedes-Benz Sprinter and the Economy

With the economy relying heavily on e-commerce and delivery services, the Mercedes-Benz Sprinter will play a significant role in its continued growth. Earlier this year, Amazon announced that it will be purchasing 20,000 Sprinter vans for its new Delivery Service Partner program. That alone shows how reliable the Sprinter vans are.

In order to fulfill this order and future growth in the United States, Mercedes-Benz announced a new $500 million investment in a manufacturing plant in South Carolina. The 2019 model is full of modern gadgetry that you find in passenger vehicles and will be the model that Amazon will first start using for its new delivery program.

The Sprinter has been around since 1995, so that gives us enough time to understand what common problems drivers/owners are reporting. Also, understanding the common problems with Mercedes sprinter vans allows fleet managers to plan and budget accordingly.

Common Problems with Mercedes Sprinter Vans

While there aren’t too many problems people report with the Sprinter, these vans are constantly on the road working. So, problems are bound to arise, no matter how well they are designed. Furthermore, because of the wear and tear of the vehicles, owners can expect to pay a significant amount of money in annual repair costs. More specifically, brake pad and broker rotor replacement, brake caliper replacement, and a starter replacement. That said, here are the two most common problems with Mercedes Sprinter vans.

Mercedes Sprinter Not Starting

As previously mentioned, the Sprinter vans are worked very hard with a minimum of 12 hour days, so problems are guaranteed to arise. One of these issues is not being able to start the engine. There can be many reasons behind an engine not starting. In the case of the sprinter van engine not starting, there are 3 main culprits:

  1. Battery – A dead battery is the number one reason why your sprinter van won’t start. Replacing a battery should not be too costly, and it will get your van back on the road delivering.
  2. Alternator – If the battery is fine, then the next reason your Sprinter is not starting is the alternator. Alternators can either undercharge or overcharge your battery, resulting in electrical charges. It’s best to get it looked at to see if it can be repaired or replaced.
  3. Starter – A major sign of a bad starter is slow and difficult cranking. If you are experiencing this, have one of our ASE certified mechanics check it out immediately. A sprinter van that is not on the road is one that is not delivering, so schedule your appointment here to get it back on the road as soon as possible.

We have locations in Texas (Dallas, Uptown, and Houston) and Georgia (Alpharetta, Buckhead, Duluth), so make sure to give us a visit to help you diagnose any common problems with Mercedes Sprinter vans.

Mercedes Sprinter Van AC Not Working

Again, these vehicles are pushed to the limits and issues are expected. Another reported problem with Sprinter vans is the AC not working. And there are common reasons why this is occurring:

  1. AC Refrigerant Leak – With so much wear and tear occurring with these work vans, the probability of an AC refrigerant leak is high. And if that is the case, then the AC will not work. It is hard to spot a leak with the naked eye, so make sure to get it checked by a certified professional mechanic.
  2. Electrical Issue – In some cases, the cause of the AC not working is electrical. This can affect most component of the HVAC system, such as the AC compressor and AC condenser. Your best plan of action to is to have one of our service mechanics diagnose your Sprinter van.
  3. AC Compressor – the least common reason why the sprinter van AC is not working is the AC compressor. This the easiest one to diagnose. For example, if hot air instead of cold air is blowing from the vents, it’s a problem with the AC compressor. You may also hear noise when starting up the AC. If you do, then your AC compressor needs to be repaired or replaced.

Having an AC system that works is important to keep drivers comfortable. The more comfortable they are, the more they can deliver, so it is important to get this common problem with Mercedes Sprinter vans fixed. Schedule your appointment today.

Brake Repair Services

Brake Repair

The use for brakes naturally arose when humans began traveling using transportation techniques other than their legs. Whether it is by land, air or sea, the need for brakes mitigates the risk of accidents which cause injuries and even death. With the popular rise of the automobile in the United States, accidents became a daily occurrence. However, two things occurred which increased fatalities: 1.) High-speed highways became the norm, and 2.) Vehicles became cheaper but more powerful.
Since fatalities from car accidents were on the rise, society realized that safety standards need to be developed and enforced to protect consumers. So, by 1970, the National Highway Traffic Administration was formed to combat the rise in fatalities and instill a culture of “safety first” in automobile design.
Recently, the NHTA is now adding the need for an Automatic Emergency Braking feature to qualify for a 5-star rating. So, having a well-designed braking system is a big part of an overall process of avoiding injury from car accidents. But how do car brakes work?

How Brakes Work

Understanding how brakes work will help you look out or any irregularities in your braking system, therefore increasing safety on the road for everyone. The braking systems of today use multiple sensors and electronics to stop a car as quickly as possible. Nonetheless, the primary braking system is still used.
When you press the braking pedal, that pressure moves a piston in the master cylinder, forcing braking fluid to enter the brake lines to the calipers and wheel cylinders. The force applied to the brake pedal is therefore proportional to the force applied to the pistons.
The calipers in disk brakes and wheel cylinders in drum brakes are connected to disk pads and braking shoes respectively. The pistons push the disk pads or braking shoes onto the rotor or wall, causing friction and resulting in the decreased rotation of the wheel.

Components of the Braking System

Braking systems include either disk brakes or drum brakes. Disk Brakes are comprised of a disc/rotor, calipers, disk pads and hardware necessary to mount the components to the car. The caliper is connected to the hoses and wires that send the braking fluid when the brake pedal is depressed.

Drum brakes are comprised of a drum/braking plate, brake shoes, a wheel cylinder, and hardware to mount the components. The wheel cylinder is connected to the hoses and wires send the braking fluid when the brake pedal is depressed.

Braking Fluid

Water used to be used as a braking fluid in the past. However, the braking process causes temperatures to rise past the boiling point of water. This causes water to vapor resulting in brake failure.
Braking fluid is a hydraulic fluid with a high boiling point. Hydraulic fluids are used to transfer power, in this case, from the pedal to the calipers and cylinders while surviving high temperatures caused by braking. Braking fluid also protects against corrosion of systems it comes in contact with.

When to Schedule your Car for Brake Services

This is what to look for to bring your car in for brake services:
  • Noise or grinding coming from the brakes
  • Brake pedal feels spongy or soft when pressed
  • Car veers a certain way when the brakes are pressed
  • Brake fluid level in the master cylinder is low
  • Brake system Warning Lamp is on
