The total repair cost will vary based on the condition of your vehicle and the number of repairs needed to fix your symptom. Proper diagnosis will save you money by finding the exact repairs needed to fix your car right the first time.
Over time serpentine belts stretch, crack, and the ribs that ride on the accessory pulleys being to wear smooth. A squealing noise that increases with engine speed or as engine driven accessories are turned on may be noted. The noise is caused by the belt slipping on the pulleys, insufficiently driving them. Ineffective air conditioning, a battery warning light, or intermittent power steering assist can result from this.
The bad thermostat can cause two different sets of problems, depending on whether it's stuck open or stuck closed.
A thermostat that is stuck open can cause the engine to run colder than normal and turn on the check engine light. It may also cause poor fuel mileage and the heater to blow cool air.
A thermostat that is stuck closed will cause the vehicle to overheat. If a new thermostat doesn't resolve engine temperature problems, the cooling system needs to be checked for other issues.

When the engine coolant temperature sensor fails, it will send inaccurate information to the vehicle’s computer, causing the computer to react to false operating conditions. This will cause the engine to consume more fuel than normal, depleting fuel mileage, and causing black, sooty smoke from the engine under moderate to heavy acceleration. The check engine light will illuminate, and on-board diagnostic trouble codes may be stored for exhaust and emission system failure, fuel delivery system failure, and engine cooling system failure. Overheating may also occur, as the coolant sensor may be leaking fluid out of the engine, creating a an air pocket in the system.
When the radiator fans stop functioning properly, the engine temperature will rise. The spike in temperature will be highest when the vehicle is idling at a stop, but should subside once the vehicle begins moving again.
Additionally, the air conditioner typically won't blow as cold. This is because the air from the radiator fans also blows across the air conditioning condenser, so when the fans fail, both systems suffer.
You'll also usually see the check engine light and notice a drop in fuel economy. It's possible the fan will start making noise if it's failing, as well.
When troubleshooting radiator fan issues in your Ram ProMaster City, it's essential to adopt a systematic diagnostic approach. Start by checking the fan's operation; listen for any unusual sounds or observe if the fan runs continuously even when the engine is off, which may indicate a communication error or a malfunctioning fan. Next, inspect the cooling fan relay located in the fuse relay box under the hood. A faulty relay can disrupt the fan's operation, so replacing it might be necessary. Additionally, examine the engine cooling fan resistors, as these components regulate the fan's speed; if they are damaged, replacing them could resolve the issue. If these steps do not yield results, consider the possibility of needing a new radiator fan unit, ensuring that any replacement part is compatible with your vehicle model. Should you find yourself unable to diagnose the problem after these checks, consulting a professional mechanic is advisable for a thorough evaluation and solution. By following this structured approach, you can effectively address radiator fan issues and maintain your vehicle's cooling system.
When diagnosing a non-working radiator fan in a Ram ProMaster City, it's essential to understand the common problems that can arise within the cooling system. One frequent issue is a faulty fan motor or fan clutch, which can prevent the fan from operating correctly. Additionally, a blown fuse or a malfunctioning relay can disrupt the electrical flow necessary for the fan to function. The coolant temperature sensor is another critical component; if it fails, it may not send the correct signals to the fan control module, leading to improper fan operation. It's also important to check for any communication errors within the vehicle's computer system, as these can cause the fan to run continuously or not at all. By being aware of these common failure modes, you can more effectively troubleshoot and identify the root cause of the radiator fan issue, ensuring a thorough and efficient DIY diagnosis.
When the radiator fan in your Ram ProMaster City fails to operate, it’s crucial to address the issue promptly to avoid serious engine damage. A malfunctioning fan can lead to overheating, which may cause the engine to run at dangerously high temperatures, potentially resulting in costly repairs or even complete engine failure. Common culprits behind this problem include a defective fan assembly, a faulty fan clutch, or issues with the coolant temperature sensor. Additionally, if the fan relays are defective, they may cause the fan to run continuously or not at all, further complicating the situation. Given that electric radiator fans have a limited lifespan, regular maintenance is essential to ensure they function correctly. Ignoring these symptoms not only poses a safety risk but can also lead to significant long-term damage to your vehicle, making it imperative to diagnose and resolve the issue as soon as possible.
