How to Flush and Fill an Automotive Cooling System

Cooling systems in today’s vehicles are prone to problems if not properly maintained. Saving a penny or two today will end up costing you dollars tomorrow if preventative maintenance is not performed including the all-important cooling system flush and fill. Read More

The Importance of The Serpentine Belt

 Let’s talk about the Serpentine Belt. Sounds scary by name alone and thus a very important part of any vehicle. Here’s what you need to know about it and how to recognize if replacement is necessary. Read More

How the Water Pump Reduces Engine Heat

The consistent motion of the engine results in a large buildup of heat, which affects the performance of a vehicle when the amount of heat reaches a definitive threshold. Too much heat will... Read More

Identifying a Leak Within the Cooling System

 A leaking cooling system can result in costly repairs if the leak is not addressed. If the water pump has failed, then it will need to be replaced before the vehicle can be safely driven. In addition... Read More

Testing Your Engine's Electric Cooling Fan

Most vehicles that use electric cooling fans, as opposed to engine driven fans, typically have two fans mounted on the engine side of the radiator. One fan serves as the main engine-cooling fan, while the other cools the air conditioning condenser. Read More

How to Test and Replace the Engine Cooling Fan Clutch

Engine cooling fan clutches are found on conventional rear wheel drive vehicles with the front of the engine facing the radiator. There are essentially two types of fan clutches, thermal and non-thermal. Non-thermal clutches are less common and operate continuously at 30 to 60 percent engine rpm. Read More

Cooling System Freeze Plug Problems and Replacement Procedures

Engine freeze plugs push outward in the event that an insufficient amount of antifreeze/distilled water mixture in the cooling system allows the engine to freeze. When the mixture freezes, it expands. Without the freeze plugs, the engine block would crack and be unserviceable. There are generally eight freeze plugs made of steel that are evenly spaced around the engine block. Read More

The Coolant Temperature Sensor and Its Affect on Engine Cooling

The coolant temperature sensor (CTS) is one of the most important sensors. It is sometimes referred to as the “master sensor” because of the number of systems on which it relies. The CTS is a thermistor-type sensor. A signal voltage is sent to the CTS by the Powertrain Control Module (PCM).

How to Cure Automotive Water Pump Cavitation

Cavitation is the formation of vapor bubbles in the cooling system and their subsequent implosion. Vapor bubbles form in coolant when the coolant temperature increases, coolant pressure drops or a combination of a decrease in pressure combines with an increase in temperature. Read More

Preventative Maintenance for Water Pump and Cooling Systems

Most believe that the best time to do preventative maintenance on the cooling system is before summer, the hottest time of the year. In reality, you should follow your vehicle manufacturer’s recommendation on maintenance intervals. Cooling system issues can cause major headaches no matter the time of the year.

How the General Motors LT1 Reverse Flow Cooling System Operates

In 1992, GM introduced the LT1 engine, a revolutionary new 350 CI small block to be used in all its rear wheel drive vehicles. All of these engines from 1992 through 1997 use a reverse flow water pumps that is driven directly off the camshaft. Read More

8 Possible Reasons For Breakdowns In Automotive Cooling System

The function of the cooling system in any automotive engine is to remove the heat that is produced during combustion by circulating the coolant between the radiator and the engine. The cooling system of a vehicle includes important parts like radiator, pressure cap, cooling fan, thermostat valve, water pump, temperature gauge, hoses & pipes etc. It is essential that vehicle owners should ensure proper working of these components to maintain the overall health of the automotive. Malfunction or breakdown of any one of these parts can cause engine issues such as overheating, poor performance and failures. It is essential to check the cooling system periodically for potential problems to avoid unnecessary damage to engine. Read More

Different Types of Cooling Systems In Automobiles

When an automobile engine gets heated while running, it is the job of the cooling system to reduce the heat and protect the engine from overheating. Irrespective of the outside temperature, the cooling system has to keep the engine at right temperatures, not too low or high, but at a moderate constant proportion. Excessive cooling reduces vehicle fuel efficiency whereas overheating damages the engine. Typically it is the responsibility of cooling system to dissipate excess heat into the air and keep engine operating at its most efficient temperature. Automobiles use two types of cooling systems air cooling and liquid cooling systems. Read More

Water Pump and Timing Belt Replacement

Both the water pump and timing belt are important when it comes to engine maintenance. So, while you’re going through the difficulty of replacing the water pump, save some time and labor costs by replacing the timing belt at the same time.

How Long Do Water Pumps Last? Consider These Factors.

The lifespan of a water pump varies from manufacturer to manufacturer, but most last from 60,000 to 100,000 miles or more. Most pumps are replaced prior to failure as they are replaced in a lot of cases with the timing belt.

How to Check for Leaks in an Automotive Cooling System

Cooling system leaks can be internal or external in nature. Either one is cause for concern and immediate attention to head off any possibility of overheating or catastrophic engine failure.

Flex Fans Versus Clutch Fans - Their Pros and Cons

Engine cooling fans are necessary to draw air through the radiator while the vehicle is moving at a slow speed or when at an idle. When the vehicle is moving at sufficient speed, air is being forced through the radiator at a greater cubic feet per minute (CFM) than the fan is capable of, making the fan redundant.

Cold Weather Cooling System Protection

The weather in most parts of the country is bitterly cold right now, and much of the country is blanketed in a thin (or even not-so-thin) layer of ice and snow. Even areas that typically never see snow or ice are shut down due to the severe winter storms that 2014 brought with it.

Diagnosing Overheating Problems on Vehicles with Electric Fans

Engine overheating is a serious problem that can swiftly cause catastrophic damage to the engine. Engines, being a thermal device, are subject to contraction when cold and expansion as their temperature rise.

Heater Malfunctioning May Not Be a Cooling System Problem

Vehicle AC and heating systems have many common parts, which work synchronously to produce warm or cool air for the driver and passengers. Unfortunately, a single malfunctioning part or improper installation can result in failure or decreased capacity of the heating and air conditioning systems.

How Difficult Is Water Pump Replacement? Can Anyone Do It?

The location of the water pump in relation to the engine can vary by application. Whether you can replace it yourself depends on how much experience you have.

Consequences of Overheating

It is hard to disagree that one of the most destructive things a person can do to their vehicle is to allow the engine to overheat. Severe overheating can render the engine -- and many of its component parts -- completely useless, resulting in a large repair bill.

Evolution of the Automotive Radiator

From the time of the very first vehicles until the '70s, radiators were made of a combination of brass and copper. No other material could compete with this combination in terms of heat dissipation, resistance to corrosion and ease of repair.
