  What Does the Water Pump Do? The water pump is a crucial part of your vehicle’s cooling system, it’s hard to find a car without one. This week, we replaced the water pump on a 2005 Toyota Avalon, which got us thinking: What exactly does the water pump do, and how common are failures? The pump circulates coolant (antifreeze) through the engine block, absorbs heat, then sends that hot coolant to the radiator where it’s cooled and recirculated. If the pump fails or leaks, coolant may not circulate properly, leading to engine overheating. Today, we’ll dive into common Toyota water pump issues, though these problems can occur on all makes and models. Why Does a Toyota’s Water Pump Leak? There are several common causes of water-pump leaks. Here are the main ones: 1. Seal and Gasket Wear or Failure Over time, the shaft seal (which surrounds the impeller shaft) or the mounting gasket can wear out, bec ... read more

    If you own a Subaru, you already know they’re well-loved for their reliability, safety, and all-wheel-drive performance. But there’s one issue that some Subaru owners have experienced over the years — excessive oil consumption.

At Dickerson Automotive in Spanish Fork, we often get calls from Subaru drivers wondering, “Is it normal for my car to burn oil?” Let’s take a closer look at why it happens and what you can do to keep your engine healthy. Why Some Subarus Burn Oil Oil consumption can happen with any engine, but it’s been more common in certain Subaru models and years — especially those equipped with ... read more

 Understanding the New A/C Refrigerant 1234yf: What You Need to Know If you've had your vehicle's air conditioning serviced recently or drive a newer model, you may have heard about 1234yf refrigerant. This newer A/C refrigerant is quickly replacing the older R-134a in many vehicles — and for good reason. So what is 1234yf, why are manufacturers switching to it, and how does it affect you as a vehicle owner? Let’s break it down. 🔧 What Is 1234yf Refrigerant? 1234yf (short for HFO-1234yf) is the next-generation refrigerant used in vehicle air conditioning systems. It's designed to have a much lower impact on the environment compared to older refrigerants — especially R-134a, which has been the standard for decades. 1234yf is a type of hydrofluoroolefin (HFO) refrigerant. It cools just as effective ... read more

Active Fuel Management (AFM)—also known as Cylinder Deactivation—is GM’s variable-displacement engine technology. It's designed to improve fuel economy by allowing V6 and V8 engines to deactivate cylinders under light-load conditions, such as steady highway driving. When deactivated, these cylinders are closed off and filled with trapped air, effectively turning them into air springs. This reduces energy loss through pumping, helping the engine run more efficiently while maintaining a smooth driving experience. 👨‍🔧 How AFM Works 🔧 Hydraulic Lifter Control AFM uses a combination of solenoids and hydraulically-actuated lifters, located in the engine valley, to disable specific intake and exhaust valves. These lifters, supplied by Eaton and Delphi, temporarily prevent certain cylinders from firing, allowing the engine to operate in a leaner mode when full power isn't ... read more

When you're cruising down the freeway, you expect the road to be clear—free of hazards and distractions. But one of the most common yet often overlooked threats to your safety is loose debris that may suddenly appear in your lane. Loose items or parts falling from other vehicles can lead to serious accidents, vehicle damage, and even fatalities. While debris might seem like a minor inconvenience, it can cause life-altering consequences if not properly managed. Whether it’s a piece of machinery, a broken car part, or even construction materials, loose debris on the freeway can lead to catastrophic outcomes. In this blog post, we’ll explore why securing your load, checking for loose parts, and maintaining your vehicle are critical—not just for your safety, but for the safety of everyone on the road. What Is Loose Debris ... read more
