Lexus RX 300
Automotive Air Conditioning & Heating Parts

Controlling engine and transmission temperatures in your Lexus RX 300 is a difficult job. While the radiator, cooling fan relay (or fan clutch), and cooling fan keep coolant from getting too hot, the thermostat makes sure the antifreeze doesn't get too cold. The area in between is the ideal operation range for your engine. Other fluids rely on an engine oil cooler or transmission oil cooler to keep operating temperatures in check. Your local NAPA has all the your engine heating and cooling system needs, including import fluids like Altrom Pentofrost antifreeze.

Several factors can affect how well your Lexus RX 300 handles the heat. A worn out water pump not only fails to move coolant, but it can also be the source of a coolant leak. A stuck heater valve or leaking heater core won't just leave you cold, it could leave your floorboards or fan blower motor wet. Your radiator cap may seem simple, but it is a critical component in controlling how much heat your cooling system can absorb. And while an oil change may be in your routine maintenance, you need to consult your owner's manual to find out when an antifreeze change is due.
