Experienced mechanics share their insights in answering this question :
Hi there. If all the mountings are secure, the only thing I can think of is something that is pushing the fan into the radiator. Have the engine and transmission mounts checked. If the engine and transmission are moving around more that normal, the engine may be bumping the fan into the radiator. You may want to try having another qualified professional take a closer look at the car in order to see if they can pinpoint the cause of this problem.

Any time fan blades hit the radiator, it`s worth a look at both the water pump shaft freeplay and at the motor mounts (and trans mounts while you`re at it). The aforementioned parts do fail, and when they do the fan can hit the radiator. You must remove the belt in order to check shaft freeplay.
The most common reasons for a radiator fan not working can be a blown-out fuse, a bad relay, or a broken wire. The faulty coolant temp sensor might also be a reason behind it. Whatever the case, a dysfunctional radiator fan can be fatal.
The radiator fan (or fans) pulls cooling air through the car`s radiator. Positioned between the radiator and engine, cooling fans are particularly helpful when the car is stationary or moving at speeds too slow to force air through the grille.
A pusher fan, in the context of a car`s cooling system, is a fan mounted to the front of the radiator. Most often, a pusher fan is used in cars with significant aftermarket modifications and is typically an electric fan.
If you are wanting to try and resolve this yourself, then first turn off your heating, and ensure you have a valve key to loosen the valve at the top of your radiators. This is called “bleeding the radiators”. You can also ask your plumber to do this as part of your boiler servicing.
If your cooling fans are working, but the engine still overheats, the radiator itself might be going bad. Over time, rust and corrosion can disrupt the flow of coolant through the radiator, meaning it can`t do its job as effectively.
If you`re a DIY person, learning how to fix a radiator fan can help you save your car engine from damage. Overheating issues often result from bad cooling fans. If you know how to, you can easily correct them. This chapter will show you how to repair a radiator fan using only a few tools.
The cooling system is one where air bubbles can be a significant concern. They can lead to hot spots in the engine, which can cause it to overheat and lead to all sorts of internal engine damage that will be costly to repair.
A faulty radiator fan can cause many problems. These are some of the most common: Engine overheating: A bad radiator fan can cause the engine to overheat, especially at low speeds. If your car starts overheating, pull off the road as quickly as you safely can and turn off the engine.
Electrical fans can either push air through the radiator or pull air through it. A pusher fan sits in front of the radiator. When a vehicle is moving, a pusher fan can obstruct airflow due to its positioning in front of the radiator. A puller fan on the other hand sits right behind the radiator.
Generally, you want the case fans in front of the case drawing in air while the fans at the rear blow air out. If your case has vents at the top, they should be placed as exhaust fans because hot air will rise.
Signs and symptoms of radiator airlock include: Overheating during normal driving. Heater not functioning correctly. Reduced performance.
Worn bearings, bent or broken blades, and unbalanced rotating assemblies can cause a fan to screech, howl, or otherwise make noises it shouldn`t. Fortunately, switching out a worn fan for a new one isn`t a huge ordeal.

An unlikely, but possible, cause is a bad thermostat. Try turning the Fan switch to the “On” position to see if the blower comes on.

Radiator fan cycles on once then never again
ANSWER : Hi, thanks for writing in. There is a pressure sending unit that is used by the AC system that runs the radiator fans to maintain proper head pressure (mounted on the top of the accumulator). If this unit is defective, the computer goes into a default mode and runs the fans. I would recommend having an expert from Your Mechanic come to your home to diagnose and repair. I recommend having one of our certified automotive technicians from YourMechanic come to your home or office to inspect, diagnose, and repair the issue.

Car will overheat if I don’t have the fan on. When fan is off it doesn’t come on to release heat from engine. So the fan is always on.
ANSWER : Check the wiring to the coolant temperature sensor and see if there is power to the sensor switch. If there is no power, then check the cooling fan relay and see if its clicking on. If there is no clicking motion, then remove the relay and check for power to the relay. If there is power to the relay, then the cooling fan relay needs replaced. If there is no power to the relay, then check the fuse. If the fuse is burned, replace the fuse. If the fuse is good, then check power from the fuse to the main circuit on the fuse box. If there is no power, then the fuse box needs replaced. If the fan comes on with the air conditioning system switch turned on, that is because the switch overrides the cooling switch to make the condenser cool down to make the air conditioning system work properly.
If you need further assistance with your cooling fans not coming on when the engine gets hot, then seek out a professional, such as one from Your Mechanic, to help you.

If the wire on my radiator fan is bad, do I have to replace the entire fan?
ANSWER : A broken wire can generally fixed, but if the break is too close to the connector, you may want to replace the connector itself. If there is any corrosion inside the connector, then definitely replace the entire connector and the component it connects to for the best result. Consider having an experienced technician, such as one from YourMechanic, come out and take a closer look to offer a more personal diagnosis on the radiator fan.

Hey Chris what direction is the radiator cooling fan Supposed to blow? Towards the engine or towards the radiator ? It is a 201
ANSWER : The fan should blow air toward the engine (i.e., same direction as the air flow when the vehicle is in motion). If the fan is not OEM, the air volume may be off and the electrical characteristics could be different. The wisest course is to remove the fan and install a GM supplied part. Furthermore, if the fan is not firmly held in place with the correct fasteners, there is a possibility of it coming loose and damaging other parts or causing personal injury. The fan must be bolted to the vehicle. If you desire that this be rectified, please request radiator fan repair/replacement and the responding certified mechanic will get this resolved for you. If you have further questions or concerns, do not hesitate to re-contact YourMechanic as we are always here to help you.

Radiator fans wont turn off unless I turn off the car, why?
ANSWER : It sounds like you have checked just about everything that controls the fans other than the fan power relay itself. As you may know the coolant fan relay turns the fans off and on by receiving information from the coolant temperature sensor at specific temperature thresholds. When this relay is not working properly, this can cause the fans to come on intermittently, stay on all the time or sometimes not at all. When this happens you will notice a temperature spike and drop occasionally as the fan comes on and off. I would suggest having an expert from Your Mechanic come to your home to diagnose your coolant fan.

Can I remove the fan clutch and put 1 or 2 fans with a thermostat to cool the engine?
ANSWER : Hi, thanks for writing in. The problem with using electric fans is the amount of air flow that the fans produce. It would not be an answer that could be answered without knowing exactly what the fans air flow is and what is required by your truck. You can try them and see if they work by monitoring the temperature in heavy traffic with the air conditioner on. If it starts getting too warm, then there is not enough air flow. Hope this helps and best of luck.

I have issues with my radiator and radiator fan assembly.
ANSWER : You are correct in thinking that the combination of leaking radiator and non-functioning cooling fan is contributing to your overheating issue. Generally, modern radiators are not repairable and will need to be replaced entirely. The cooling fans can also be sourced from a used parts dealer. It will be used, but less expensive than a new set of fans. Replacement just means that it is designed just like the OEM unit and should fit perfectly. A certified technician, like one from YourMechanic.com, will be able to inspect or replace these components for you, if you are not comfortable doing the job yourself.
