Cooling System

When you think of the cooling system on your Mazda, you may think of the radiator, but there are many other parts to this system that are instrumental in keeping your engine running cool. The radiator might be the biggest part, but without the series of hoses and connections, the coolant in the radiator would go nowhere. Engines create a lot of heat, and the cooling system must take that heat and reduce it. This prevents the engine from overheating.

Your engine should operate at a high temperature because that is where you get the best performance. The higher the heat, the less likely internal parts will wear out. The cooling system keeps the temperature at a uniform level. Your Mazda RX-7's cooling system consists of things like hoses, water pump, a pressure cap, transmission cooling lines, fan and thermostat. Every part of the system may need replaced at some point due to the tremendous amount of pressure it takes during a normal day. All that high-pressure tension on hoses and clamps can cause these parts to fail.

When you need to replace any of these parts from your cooling system, you want to use OEM Mazda parts that will deliver factory performance and be an exact fit replacement part. Some aftermarket parts may not be the right length, which may mean hoses need stretched to fit points causing stress on a part that has enough stress just doing its job.
