Message: <blockquote data-quote="sakuraguy" data-source="post: 984662" data-attributes="member: 6441">Ensure Radiator PerformanceIf your car is experiencing radiator and cooling system problems, there can be any number of reasons as to why. To help protect your car’s longevity, it is important to get your vehicle looked at by a radiator specialist as soon as problems arise. Here are seven few common radiator areas you’ll want to have checked to ensure peak performance.Check Your ThermostatEven if the thermostat isn’t the cause of the overheating problem, it should still be tested after a problem exists to ensure that isn’t damaged. One method used is to start the engine and feel the upper radiator hose. Ideally, the hose should not feel uncomfortably hot until the engine has had time to warm up. If the hose does not get hot, then this could be indicative of a thermostat failing to open. Another way to test the thermostat is to simply remove it and drop it into a pot of boiling water. It should open at this time and you can always test the exact opening temperature by using a thermometer.If you find that the thermostat needs to be replaced, be sure to install one with the same temperature rating as the one you’re replacing. Most cars and trucks built after 1971 need thermostats rated at 192 or 195 degrees. Using a thermostat with a lower rating in an effort to cure overheating can actually increase fuel burning, ring wear and emissions.Safeguard Against LeaksA loss of radiator coolant due to a leak is probably the most common reason behind a car’s overheating problems. The trouble with leaks is that the source of the leak can often be difficult to find. Possible leak areas include hoses, the radiator itself, the heater core, water pump, thermostat, had gasket, plugs, radiator cap, and much more. As you can seem troubleshooting a radiator leak can be a daunting and meticulous task.To start, try and make a visual inspection of the entire cooling system, not just the radiator. Look for any obvious signs of wear, cracking or splitting. A pressure test through a radiator specialist can reveal any internal leaks as well as seepage not visible to the naked eye. A leak-free radiator system will hold pressure for at least a few minutes.Ensure Fan HealthAlthough common and often overlooked, mechanical fans with a faulty fan clutch is often the cause behind overheating problems. This and other fan issues can reduce a fan’s cooling ability by as much as 50%. In warmer weather or under harsh operating conditions, this can absolutely be enough to cause overheating.If the fan clutch shows sign of leakage (you would notice streaks on the hub or blades), spins freely when the engine isn’t running, or seems loose when the fan is pushed, then it needs to be replaced. Failing to replace fans and maintain their efficiency can lead to overheating as the temperature continues to build unregulated.</blockquote>
