Nissan Maxima Radiator Fan Problem Indicators and How to Deal with Them
For a luxury four-door sports car like the Nissan Maxima, image and comfort are on the forefront. Imagine marring that image with such a simple, yet embarrassing, issue such as radiator fan malfunction. The radiator fan is part of the vehicle's cooling system that prevents the engine to overheat. When the radiator fan breaks, you are looking at a humiliating overheating episode. Do not fret, here are some common Nissan Maxima radiator fan issues and how you can easily troubleshoot them.
The Nissan Maxima's radiator is equipped with electric fans which are controlled by a control circuit either by a sensor, a thermal or a computer program. This control operates the fan through a relay. If the switch fails to send signal to the relay, the fan will simply not respond or operate. This means the issue is with the faulty switch relay and need to be replaced.
Thermostat's out of whack
Observe the radiator fan and start the car. Let it run for a few minutes on a minimum of 40 mile speed. If you see that the fan is turning but the temperature remains the same then the issue might be your thermostat or lack of coolant in the system. Check the level of your coolant and see if it needs to be refilled.
Blown fuse and faulty electrical wires
Here's another procedure where you can use the volt meter. Check the wires to see if there are still powers on them. The volt meter should read at least 12 volts to confirm that the blames is not on the fuse but the radiator fan. However, a reading below 12 volts means the fan needs replacing.
It's the fan
On the other hand, if the temperature becomes cooler, but the fan is not working, then it clearly points out to the radiator fan. It can be that the fan blades are broken or the fan motor is dead. Another indication that the fan is the problem is when you have to constantly replace fuses. It is definitely not normal to replace a fuse every month.
The old ones
Manual radiator fans used in the older models are solidly mounted or utilize a fan clutch. For manual radiator with a fan clutch, observe the radiator fan with the engine running. The fan should be rotating faster than the motor, if not, then replace the fan. For mounted radiator fans, when the fan is not rotating, the problem is with the belt not with the fan.
Taking Care of Your Nissan Maxima Radiator Fan
Your Nissan Maxima radiator fan plays a very significant role in your engine's cooling system. This seemingly simple contraption can actually make or break your driving experience. Imagine having your handsome Nissan Maxima breaking down in the middle of the highway because of overheating. The radiator fan keeps the radiator cool enough so that it can properly run. A malfunctioning Nissan Maxima radiator fan can cause expensive damage if left alone. Here are tips to avoid having a bad radiator fan:
Do not wait for any symptoms to force to look under the hood. Make time not just to take a peak. Start the engine and let it run. Check if the fan immediately operates after switching it on. This is the part where you can do diagnostic procedure. Check the conditions of the fan, the belt and even the coolant level.
Look at the fuse
Inspect the condition of your radiator fan's fuses. All you need to do is hold the fuses individually in to a well lit area and check for signs of damage. Also check the circuits inside, to determine which ones are already blown. Replace the blown ones with new.
When you are done inspecting the radiator fan and its surrounding components, take out the radiator fan. It is located either on the front or the back part of the radiator. Set it on a table and closely inspect it. Have a rag soaked in a de-greaser and wipe off grease, tar and dust from the fan blades. You can use pipe cleaners to rub the muck out of the hard to reach areas like in between the blades.
Put everything back
After your routine inspection and cleaning, put the radiator fan back. Make sure all screws are attached and plug it back to the wire. It's important to make sure that you put the radiator fan back properly to avoid malfunction in the future.
Out with old
Finally, if you do find yourself looking at a broken radiator fan, do not be afraid to buy a replacement. Remember that buying a Nissan Maxima radiator fan is way cheaper than risking serious damages to the engine and the radiator itself.
