Cooling System Durant OK
All engines need to be cooled in order to run properly, which is the purpose of a cooling system. Keep reading for information on how cooling systems work and how to keep them working so that they keep engines working.

Subaru: Coolant Comes out of Reservoir Durant OK
If you encounter a vehicle that experiences coolant coming out of the coolant reservoir tank, it may be caused by the radiator cap pressure valve being stuck open by debris sucked up through the reservoir tank hose. As the cooling system cools down, it sucks coolant back into the radiator.
Tech Tip: Sorento Coolant Reservoir Replacement Durant OK
Engine coolant is flammable at certain temperatures. If coolant is spilled during the service procedure, all residual coolant must be removed from all surfaces before releasing the vehicle back to the customer. Make sure that the engine has cooled down to outside temperature before starting the repair to avoid being burned by hot coolant.
Cooling System Antifreeze Requirements Durant OK
Coolant suppliers who say this is so much nonsense have developed their own proprietary OAT-based products, which they say can be safely used in all makes and all models. The Better Business Bureau challenged one coolant supplier on this claim, insisting there can be no such thing because the vehicle manufacturers all have different and sometimes conflicting coolant specifications.
Compressors, Condensers & Refrigerant Durant OK
When the A/C stops blowing cold air, most people can only tolerate the loss of cooling as long as the thermometer remains below 80 to 85 degrees and the humidity isn't too bad. Beyond that, a trip in heavy stop-and-go traffic can be a near-death experience. As temperature and humidity go up, so does the level of discomfort. Eventually, the desire to remain perspiration-free will overcome a person's desire to postpone repairs, and you'll soon see their vehicle for service.
Diagnostic Solutions: Cooling Fan Failure Diagnosis Durant OK
Most modern liquid-cooled engines use a belt-driven water pump to circulate coolant through the lower cylinder area into the cylinder head, and from the cylinder head into the radiator. A few "reverse flow" engines are on the market in which coolant flows directly from the radiator to the cylinder head, which reduces cylinder head temperatures and better controls the rate of combustion in the cylinder head.

Chrysler & Jeep Cooling System & HVAC Service Durant OK
Chrysler Technical Service Bulletin 07-002-02 says the problem can be caused by a low coolant level in the cooling system. On these vehicles, air trapped inside the cooling system can displace coolant when the system is refilled.

Cooling System Service Durant OK
Cooling system service is an absolute "must-do" on any import nameplate. Once a cooling system suffers long-term neglect, it turns into an on-going source of problems for the owner and his servicing technician because, when corrosion starts to take place, the effects can't be reversed.
Diagnosing and Repairing Cooling System Leaks on Hyundai Models Durant OK
Cooling system problems will present themselves in a variety of ways, and it’s important that your service writer has the skills to ask the correct questions that will help your techs make efficient repairs. Some are straightforward, but if the car is leaving puddles of coolant whenever it’s parked there isn’t much more you need to know. Here are informations about diagnosing and repairing cooling system leaks on Hyundai models.

Temperature Control Essentials: Pinpointing the Causes of Cooling System Failures Durant OK
If a thermostat fails and sticks shut, it blocks the flow of coolant and will quickly cause the engine to overheat. If it sticks open, the engine runs too cold and never reaches its normal operating temperature. On engines with computer controls, this can prevent the engine management system from going into closed loop, causing the engine to run rich, waste fuel and pollute.
The Heat is on...Helping Your Customers and Their Vehicles Keep Their "Cool" Durant OK
Cooling problems can be lumped into two categories: coolant leaks and overheating. The first will ultimately lead to the second. But until the loss of coolant is large enough to cause the engine to run hot, a few drops of coolant on the driveway may not seem like a big deal. Nothing could be further from the truth.
Water Pumps: Why They Fail and When to Replace Them Durant OK
Water pump operation is important because, if the coolant's circulation rate is too slow, the coolant will begin to boil in the engine's water jackets. Unfortunately, when coolant boils, it becomes gaseous and can no longer cool hot cylinder walls and cylinder heads. The result is overheating, which is a primary cause of catastrophic engine failure.
