Why is the radiator not working on my Toyota Camry?
Just because the radiator fan is not on does not mean that it is not working. They are designed to only run when needed. If your Camry is running hot, and the fan is not running we’ve laid out the most common causes of this issue below.
What should I do if my Toyota Camry is overheating?
Do not choose a caustic flush solution as the chances of radiator or heater core damage are much higher. If the radiator leaks after flushing, radiator replacement is imminent. Inspect the front side of the vehicle and radiator for any obstruction (trash, bugs, etc.) that can reduce cooling efficiency.
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.
What happens if you open the thermostat on a Camry?
As the coolant heats up, the thermostat will open to allow full flow of the coolant through the cooling system. Unfortunately, the thermostat can fail in either the open or closed position.
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 does my cooling fan not turn on in my Toyota?
The Toyota’s fan only turns on when the coolant reaches a certain temperature, which is measured by a sensor. This sensor switches the cooling fan off and on as needed. A failed sensor can cause the fan to run excessively or not run when cooling is needed. The cooling fan in a Toyota has a relay to regulate when power is provided to the fan.
What to do if your radiator fan is not working?
The first thing that you would want to do is locate the fuse for your Camry’s radiator fan and make sure that it hasn’t blown. If it is blown, replacing the fuse will only solve the problem for a very limited period of time. Unless the wiring issue is fixed, the fuse will blow again.
Where is the radiator fan fuse on a Toyota Camry?
The radiator fan fuse is usually located in the under hood fuse/relay box. 2. Jump the radiator fan motor and ensure it runs. Disconnect the radiator fan motor connector and attach jump leads to the battery. Better yet, use a Power Probe II–it’s safer, since it is fused. 3.
Why are the radiator fans not coming on?
The only way the fans come on is if the a/c is on or if I disconnect the wire to the coolant temperature switch at the radiator. I have replaced that switch recently with OEM that I got from Toyota. This all started the front end of the car was bumped but no apparent damage.
How do you change the cooling fan on a Toyota Camry?
Disconnect the cooling fan connector. Connect battery and ammeter to the cooling fan connector. Check that the cooling fan rotates smoothly, and check the reading on the ammeter. Standard amperage: 8.0 to 12.0 A at 20 C (68 F) If not, replace the cooling fan.
What should the ammeter reading be for a Toyota Camry?
Check that the cooling fan rotates smoothly, and check the reading on the ammeter. Standard amperage: 8.0 to 12.0 A at 20 C (68 F) If not, replace the cooling fan. Reconnect the cooling fan connector. 1. INSPECT RELAY (FAN No. 1, FAN No. 3)
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 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.
What does the thermostat on a Toyota Camry do?
A thermostat is basically a valve that interrupts the flow of coolant through the engine when the car is cold. This lack of coolant flow allows for the engine to quickly reach operating temperature. As the coolant heats up, the thermostat will open to allow full flow of the coolant through the cooling system.
When does the cooling fan come on on a Toyota?
The cooling fan is usually activated when the air is running at medium or high speed. The fan switch is bad – The fan switch comes on when the coolant is a set temperature. You can test the switch by disconnecting the wiring harness and using a jumper wire on the contacts.
What does it mean when your radiator fan is not working?
This is what we call a blown fuse. A blown fuse is no big deal, and changing one does not cost a lot of money. If your car’s radiator fan is non-functional, check your car’s user manual and locate the fuse for the radiator fan controller or the fan.
Is there a problem with my Toyota Corolla cooling fan?
Problem: Cooling fan runs all the time. Checked the #1 cooling fan relay and main engine relay per Haynes manual, both work. Temp gauge on driver’s display works (temp sensor works). Ideas? Not clear to me if this car has a engine coolant temp (ECT) switch, or if the fan is controlled from the ECM. Background: ’99 Toyota Corolla (5 spd, 1.8L).
