Cooling System

In our experience, for every engine problem related to changing oil, we see 100 times the problems related to the cooling system.

While you often hear how important it is to change your oil every 3,000 miles, you don’t hear enough about how important it is to cleanse, change and maintain your cooling system. If you don’t change your coolant, it will eventually change from a corrosion inhibitor to a corrosion accelerator.

Your cooling system is what keeps your car from a catastrophic failure. If your engine didn’t have some way to cool off, it would turn into a frozen block of metal . The purpose of the cooling system is to take heat away from the engine. Lack of cooling can cause catastrophic short term problems and engine failures. It can also cause long term damage to the engine. You need to have a full capacity of fresh coolant moving efficiently through the engine to avoid short term and long term problems.

Inspection

Engine combustion temperatures can reach 2000° F and higher. If your engine is running hotter than normal, either shortly after starting or over time, it’s probably time for an inspection.Check to see if there is any green, orange, or yellow fluid spots or puddles under your vehicle. If there is, you are probably losing coolant, which could indicate a leak in the system. This could be caused by loose or improperly adjusted belts and hoses, leaking gaskets or components, or possibly mechanical engine damage could be the culprit. Your Taskers mechanic has the knowledge expertise to correctly diagnose and repair your system so you can stay cool under the collar and under the hood.

Anti-freeze

The primary differences between the different brands of antifreeze are the type and/or quantity of anti-corrosion additives that are used. Ethylene glycol is the primary component of anti-freeze, and this never wears out but the anti-corrosion additives do. That’s one reason why antifreeze should be changed every two years (except for long life antifreezes, which have special additive packages that allow them to go up to 5 years/150,000 miles between changes). For the environmentally concerned, propylene glycol (PG) antifreeze is also available at slightly higher cost. PG antifreeze is less toxic than ethylene glycol. Remember that ethylene glycol is a hazardous waste and should not be allowed to enter the storm drain system.

Taskers Automotive has a special machine that uses a vacuum to completely remove all the old corrosive antifreeze before replacing it with fresh antifreeze.

Engine Cooling System Components:

Radiator — Coolant that has traveled through the engine is pumped through the tubes of the radiator and is cooled off for another round. The center of the radiator is called the core. Cooling fins surround the core. While you drive, air passes through the fins, the coolant releases its heat to the fins, which dissipate the heat. If your car is parked, an auxiliary fan may turn on to provide some cooling. Anti-freeze corrosion inhibitors help keep the coolant pathways clear. Radiator leaks can cause loss of coolant. Corrosion can result in either leaks or blockages. If there is not a full flow of coolant through the radiator, there will not be a sufficient heat loss through the radiator. The coolant will not cool completely and that can result in short term problems, long term problems, and maybe even engine failure.

Radiator top hose helps move the coolant from one place to another. It should be sturdy and flexible enough to handle engine vibration and high heat, and should not have any leaks. If the engine is cold, try to squeeze the hose. If you can easily squeeze the hose you should probably have it replaced. If you aren’t sure which is the cooling hose, stop by for a free inspection.

Radiator bottom hose helps move the coolant from one place to another. It should be sturdy and flexible enough to handle engine vibration and high heat, and should not have any leaks. If the engine is cold, try to squeeze the hose. If you can easily squeeze the hose you should probably have it replaced. If you aren’t sure which is the cooling hose, stop by for a free inspection.

The Radiator Cap is designed to seal the cooling system to a specific pressure.

Water Pump is the heart of the engine cooling system. It pumps coolant through the whole cooling system, and into the engine block. It is usually driven by a belt. Our free inspection will check to see the belt’s condition.

Thermostat — just like on your home furnace, water tank, or air conditioner, the engine thermostat keeps the engine at the proper operating temperature. The thermostat regulates the flow of coolant so that depending on the temperature of the coolant and the engine it cools down more or less. It rests in a housing just after the radiator bottom hose.

Thermostat Housing

Electric cooling fan pushes air through the radiator when the engine is running but the vehicle is not moving or for when the coolant temperature is too high.

Thermo-time switch or fan switch senses the coolant temperature and starts or stops the Electric Cooling Fan

 

 

Taskers repairs and maintains your vehicle air conditioning and climate control

The climate control works much like your air conditioner, refrigerator, or aerosol can.

Vapor is condensed into a liquid under high pressure. An expansion valve releases the liquid into a larger volume. As the liquid to vapor expands, the volume increases, the pressure decreases, and heat is absorbed. The vapor feels cool. This cools the air flowing into your vehicle. The expanded air coolant is then compressed and condensed back into a liquid. This is a continuous process.

In order to be effective your climate control or air conditioning sysytem needs to be filled to the proper level with coolant and maintain the proper pressures throughout the system. If there are any leaks you can lose coolant and/or lose pressure.

Taskers Automotive can check your air conditioning system to make sure the vehicle’s system has the proper system pressure and liquid volume.
