Infiniti I30 Radiator Fan
Uncover the Mysterious Problems of Your Infiniti 130 Radiator Fan
Your Infiniti 130 radiator fan is supposed to regulate the hot and cold air inside the cabin so that you and your passengers can keep your cool. The fan is also supposed to circulate the radiator fluid through the radiator while providing cool air to the engine block itself. Because of these important functions, having a broken radiator fan can really make things hard for you. Just like your famous fictional detective, you need to do your own deducing in order to figure out what's wrong with your Infiniti 130 radiator fan.
The mystery of the fuse
Because the radiator fan runs on electricity, one of the first things that fall suspect is the fuse that controls your cooling system. Locate this fuse and thoroughly inspect it for any defects. Replace it immediately if you find any. If you don't find any broken bits or burnt areas, don't let the fuse off the hook just yet. Use a DVOM to see if it has any problems that can't be seen by the naked eye. If nothing turns up, return into its hole.
The mystery of the fan wires
If it's a case of not having your Infiniti's fan kick in after the engine starts, then it could be because of the fan wires. Use a voltmeter to check if both the positive and negative feed wires are putting out 12 volts. Take out these wires if they are faulty and install new ones. Use the voltmeter on the fan relay as well. If this is faulty, find a replacement with the right CFM rating.
The mystery of the fan clutch
The fan clutch isn't some mysterious artifact, but it does have some value to your Infiniti. It can turn your radiator fan even as it holds it against the engine. You'll be able to tell when this piece is burnt out or broken so replace it when you see any problems.
The mystery of the temperature sensor
If your radiator fan doesn't come on even after your Infiniti becomes hotter under the hood, then your problem could lie with a faulty temperature sensor. This component is guilty of not noticing that your engine is about to overheat, so you'll need to take it out and get a new one.
