    • Performance Engine Cooling
      Hot Under The Hood? Performance Cooling Fans Chase Away Excess Heat
      Auxiliary fans are great for providing a boost to your vehicle's original cooling system if you've encountered overheating conditions. For those who live in climates that see high temperature and humidity, excessively high coolant temperatures can be a major problem - one that will not go away if ignored. Aluminum engine blocks and cylinder heads found on most of today's cars are much more sensitive to overheating than traditional engine blocks made of iron. All it takes is one stretch of time with parts reaching excessively high temperatures to cause permanent metal warpage, leaks, and damage to a myriad of moving parts.

      Auxiliary Oil Coolers Keep Engine Oil Temperature Under Control
      You may have seen Performance Engine Oil Coolers for sale on our website or elsewhere, and your first reaction may have been "who needs one of those? Not I." We can't say we blame you if your presumption is that either a) your engine is cooled by liquid antifreeze/coolant, so this thing can't be for you; or b) the word "performance" led you to conclude that hot-rodders are the primary target for these add-ons. In fact, if you tow a trailer, or tend to load up your SUV to the max, or drive at high speeds in very hot summer climes, you just might be the real target customer for an engine oil cooler. Allow us to provide some educational background on motor oil, and the critical roles (plural) it plays. Please read on!

      Antifreeze Explained: What It Does And Why It's Needed
      "Antifreeze" is a chemical, primarily consisting of ethylene glycol, which when mixed with water serves to lower the freezing point and raise the boiling point of the mixture. Traditionally, the combination of antifreeze and water is known as "coolant". As opposed to air-cooled vehicles which rely on fan-driven air blowing over engine components, water-cooled engines use a radiator, water pump, thermostat, heater core, hoses, and passageways within the engine.

      Servicing Your Vehicle's Cooling System
      Everyone knows that your vehicle's engine needs its oil and filter changed at regular intervals. Most folks also know that there are other items which need regular servicing and replacement, such as the air and fuel filters. But what about the cooling system? The fact is, a modern vehicle's cooling system does such a great job at preventing an engine from overheating that we all but ignore it. The reality is, all vehicle manufacturers have a recommended interval when the coolant should be replaced.
