How can I tell if my Camry fan is bad?
The fan wiring is some of the more vulnerable wiring in your Camry. You can test the voltage going from the fan relay to the fan itself. If it is getting 12+ volts, the fan should be coming on. But if it’s not, which means the fan has gone bad.
Why does my car have a radiator fan?
You probably already know the purpose of the radiator and the cooling system in your car. When you are driving fast, the wind is passing through the radiator to cool the coolant down without issues, but when you are driving slow, there is no wind pushed through the radiator. This is why we use a radiator fan.
Why is my radiator fan not working on my Buick Rendezvous?
If the engine coolant level isn’t high enough to keep pressure in the engine it will run hot. But, there won’t be enough coolant to reach the temperature sensor. Without the coolant hitting the sensor, the temp reading will be significantly lower than the actual engine temp.
Why do you need a radiator fan in a car?
To stop the engine from overheating, we take the help of coolants that flow through a radiator into the engine. The radiator’s job is to keep the coolant cool so that when it returns back into the engine, it is able to absorb more heat. A radiator fan is thus used to keep the temperature of the coolant in check. Thus, it has an important job.
How does the AC work on a Toyota Camry?

Can a / C compressor fail on a Toyota Camry?
Although highly unlikely, it is possible for the A/C compressor to fail from general wear and tear. It’s very hard to diagnose this yourself since most other compressor problems are internal. It’s recommended that you follow Step 3 before having the compressor checked. The Toyota Camry uses R134a refrigerant as part of its cooling process.
What are the symptoms of a Toyota Camry engine failure?
Symptoms include smoke coming out from under the hood, dirty coolant, white smoke coming out of the tailpipe (even after the car has warmed up), and of course engine failure. The best thing to do is periodically check your oil and inspect your coolant.
Why does my PCM not turn on the fans?
You are looking to see if the PCM sends power to one or both relays to turn on the coolant fans. This should happen as the high side of the system approaches 214 psi. If it exceeds this amount of pressure and the system doesn’t turn on, one of the sensors in the system that the PCM uses to know when to turn the system on and off has failed.
