What are the components of a radiator?
There are two main components to a radiator: the core and the headers. On automotive radiators, headers can be made of three different materials: brass, aluminum, and plastic. As for cores, they are usually made of copper or aluminum.
The core of the radiator is composed of tubes and fins. At each end of the core are the headers which include an inlet/outlet for engine coolant, and sometimes include a transmission oil coolers and/or an engine oil cooler which is inserted inside one of the headers.
How does a radiator work?
To cool down the engine, hot coolant flows from the engine into header via the inlet and then cools down as it circulates through the tubes to the opposite header and cold coolant exits back into the engine via the outlet and the cycle is repeated. As it circulates through the tubes, the coolant transfers its heat to the tubes which, in turn, transfer the heat to the fins that are lodged between each row of tubes in a zig zag pattern. The fins then radiate the heat transferred by the tubes to the surrounding air, hence the term radiator.
Engine oil coolers and transmission oil coolers function the same way. They sit inside the header where coolant circulates and the heat carried into the coil of the cooler by the hot oil is transferred to the coolant outside the coil and is dissipated as it circulates through the core of the radiator.
What Causes an Engine to Overheat?
• A major cause of an overheating radiator is an inadequate level of coolant, which can be caused by a lack of proper maintenance or a radiator leak. Other possible causes include a defective radiator hose, an improperly functioning thermostat , or a radiator cap that is not tightened correctly. A loose water pump impeller may also be the culprit.
When is an Engine Too Hot?
• Generally, modern engines will be considered "cool" to temperatures up to 220 degrees Fahrenheit, which is when antifreeze normally begins to boil. As long as no other problems are present, the safety limit could extend to 265 degrees. Because of the materials used in construction of modern-day engines, there is less margin for error when it comes to overheating.
What Else Does Overheating Do to an Engine?
• When a radiator overheats, the engine will lose power and eventually shut down. If the vehicle is driven too long while overheating, damage to the engine can occur, such as blowing the head gasket or damaging rings and pistons. Damaging hot spots that result in erratic engine combustion may also be present.
What is the Proper Antifreeze Mix in Cold Weather?
• There is no need to fill your radiator with straight antifreeze at any time, even in the winter. Virtually all antifreezes are designed for a 50/50 mixture of water and antifreeze. The only exception would be in extreme conditions, when temperatures reach below 34 degrees Fahrenheit. In these conditions, the amount of antifreeze can be increased to up to 69 percent.
What are Common Signs of Poor Radiator Maintenance?
• A common problem is not replacing the belts and hoses as recommended by the manufacturer. Not flushing older radiators can result in their clogging and eventually overheating. An improperly installed thermostat will also result in the radiator overheating, as will leaks due to improperly installed hoses.

A. Yes we do. They will be more than happy to tell you about our services.
Do a preventative cooling system maintenance check at least once every two years.
#1 A radiator pressure cap test to check for the recommended system pressure level .
#2 A thermostat check for proper opening and closing.
#3 A pressure test to identify any external leaks to the cooling system parts; including the radiator, water pump, engine coolant passages, radiator and heater hoses and heater core.
#4 A visual inspection of all cooling system components, including belts and hoses a system power flush and refill with car manufacturer's recommended concentration of coolant.
#5 An engine fan test for proper operation. By performing regular checks, You can prevent problems, emergency repairs and/or replacements, effectively saving you time, trouble and money.
Flush and repair: We remove the radiator from the vehicle, Then it is cleaned externally using a powerful spray gun and flushed internally. Then we pressure test, inspect and repair as needed.
Clean and repair: We removed the radiator from the vehicle, Then we clean it and flush it internally by cleaning it in a specially formulated cleaner. It is then flushed, pressure tested, inspected and repaired as needed.
Rod-out and repair: We remove the radiator clean it externally and flush it internally by immersion. It is then pressure tested, inspected and repaired as needed. One or both tank (tanks) is removed and a rod is inserted into each tube to remove debris. Once complete, the radiator is reassembled and tested.
Recore: When a radiator core is to weak to hold up under normal operating conditions or it has been damaged beyond repair a new core must be installed.
Plastic radiator tanks and gasket replacement: We removed the radiator from the vehicle and detach the damaged tank and gasket. The tank and gasket is replaced with new parts and the radiator is tested.
Rebuilt radiator: We remove the radiator from the vehicle, We then remove both tanks from the core. we inspect the flow of the core and if needed we rod-out the core. We then place the radiator into a ultrasonic cleaner to clean the tube to header joints. It is then flushed and all the tubes are soldered at the header joints. The tanks are install and it is pressure tested.
