There are 2 fans on your motor , air con fan comes on when the air con is switched on. The engine coolant fan comes on when the motor reaches operational temp, around 85 to 95 degrees . there is a heat censer on the engine block or radiator that controls battery voltage to the fan. with a volt meter check both sides of this censer for battery voltage, with the engine hot. replace if faulty.

SOURCE: Cooling fan wont work

The water temp sensor is located near the thermostat housing. This sensor is what tells the ECM to turn the fan on/off. The water temp sending unit is located near the same area. You know you have the correct sensor is because the water temp sensor has a 2 prong plug. The water temp sending unit only has 1 prong.

SOURCE: cooling fan

Whoever told you the temperature gauge on cavalier is normal 3/4th is the lie. It is however in operating temperature range but on the hot side. Have you flushed your coolant and replaced thermostate, and gotten air vapor locks out.

I have a 1994 honda civic I have over heating problems the radiator,temperature sensor have been replaced it runs fine for a week or two and the problem starts all over

Are you sure is your temp sensor have you check the thermostat or the cooling fan if they are working properly? Most of the honda civic has problem with the fan relay or maybe you water pump that is going bad

Radiator fan won't turn on at all

on the 92 civic you have 2 sensors for the coolant, one is a coolant fan switch and the other is a temp sensor. the fan switch tells the computer to turn on the fans at a certian temp. i would suggest replacing the fan switch which is located on the thermostat housing. if that doent work it could be the relay. I have owned my 92 civic hatch for 10 yrs and have done all the work to it myself. Also a mechanic by trade. Hope this will help you out

My honda civic radiator blowup what can be the fault

Hi!!
A radiator can blow up due to several reasons, the main and most frequent are:
  • A faulty Thermostat.
  • Low or leaking Coolant,
  • A defective or unplugged Coolant Temp. Sensor,
  • Defective Water Pump,
  • Faulty Radiator Fan Relay or blown Fuse.
  • Faulty Radiator Fan Motor or wiring,
  • Clogged Cooling System passage or Radiator.
  • Worn out (too soft) Radiator Hoses.
  • Wrong size Radiator Cap.
  • Dirty A/C Condenser Coil (the coil in front of the radiator)
Good Luck!!! A HELPFUL - 4 THUMBS - rating for this solution would be greatly appreciated. Thank you for using FixYa.

99 honda civic lx, my fans are'nt turning? Could this be a fuse??

Do you mean radiator fans or heater fans?

If radiator fans, they don't work all the time, but only when it gets too hot. When the car is not moving, they will usually go on eventually. But in normal speeds, you don't need fans.

If there is a problem, it is usually the relay, but could be the ground, one of two fuses, or the temperature sensor. The main fuse is a big one, because they draw more electricity then anything else. The switch is usually in the radiator, and powers the relay primary from a small fuse. The relay secondary then goes from the large fuse to the fan, and back through ground.

Let me know if you mean the heater fan.

check and make sure both fans are working properly. you can do this by jumping it directly to the battery and see if it comes on if it doesn't the fans need to be replaced.
