I have a 1995 Honda Accord EX 4 cylinder with 140,000 miles. Occasionally once I turn the car off it sounds like it continues to run. Not sure if this is related to the cooling fan or what? It can run from 5 to 15 minutes. I believe it tends to happen after I drive longer distances and it happens more often after I have the A/C on. The car never runs hot and has not had any problems starting. Where should I start?

I would check the timing of the engine to deal with the run on after the key is turned off.

Check the coolant level, add as necessary, and then purge the air from the system using the bleeder. The fan running is okay, but watch it closely. You may have a sensor failing that is indicating the temp to the fan.

I have a 1994 Honda Accord 2.4L Automatic Transmission. When you turn the car off, the cooling fan does not turn off at all. I used to be able to pull the fuse for it, but now it stays on. I had the fan relay under the hood replaced last summer. The mechanic says it could possibly be the ECM going bad. I am stuck with this one, because it can kill the battery. Please send response.

Car is over heating. Has new water pump. Has new cooling fan. Strange thing the car will over heat and when you turn off the car the electric fan comes on.

I dont know if the car has a termistat or not. Where is it located? What can cause the fan to act strange like that.

The fan relay could be sticking. The thermostat location follow the upper hose till it meets up with a housing where the hose is clamped to-its behind the housing. If its not there do the same for the lower hose.

I just replaced the cooling fan on the driver's side of the radiator as the original one stopped working. Now the fan runs without the vehicle being warm, meaning after running the engine for a few minutes the fans starts running and continues to run after the car is off and not anywhere near operating temperature. Is the problem with the radiator fan control module/fan time relay module brain?

Hi, thanks for the donation, found this info in our database. Are there any applicable trouble codes for the fan? As you can see from the fan relay wiring, the voltage for the load/switch side of relay is hot all the time. Voltage to the coil side of relay, goes hot when the key is on, yellow wire. The relay is energized by the ground circuit , solid blue wire/s, several switches have control over the ground circuit, right now, I'm not sure which one is causing the problem?

Yes, this is normal. Many honda models had this feature to cool the engine after it was shut off. Your highest temp. Is on engine shut off. The coolant builds pressure also. The cooling also helps relive this pressure.

Cooling fan will come on and stay on now and then after ignition has been turned off. Fan will continue to run until battery has completely gone dead. I have stopped the fan by removing the relay.

Hi mike osborn,

Try swapping the relay, it could be faulty and sticking. The fan would come on for a short while after engine is turned off if the temp is high at the upper hose outlet.

If swapping does not help and the temp is not high with sufficient coolant in radiator, the thermoswitch at upper hose joint on head needs to be replaced.

Hi maxima320,

Seems the idling speed is too high or the EACV is faulty or malfunctioning tdue to lack of coolant.

Use a jumper wire to bridge the SCS and turn ignition switch ON. Count the Check Engine Lamp blinks and let me know the code. Prolonged blinks = 10. Short blinks = 1.

Electronic Air Control Valve = EACV. It is located on the intake manifold just behind the injectors with a 2 wire connector and has 2 hoses running from it, 1 to the Fast Idle valve next to it and the other to the throttle body lower end. Removal is not difficult.

I forgot to mention about the fans running after engine is stopped. It most probably is due to a bad fan relay, sticking in closed position, or there is insufficient coolant in the system which might relate to the surging.

Surging couls also be due to idle speed set too high. Check the base idling speed with EACV disconnected.

Hi taman,

Vehicle is equipped with a system to provide power to the fan for cooling when overheating has occurred and ignition switch is turned OFF.

Check the coolant level in radiator, if it is low, it would cause the fans to work when ignition switch is turned off.

If coolant level is correct and you do not have overheating issues, the fan switch located at upper hose housing on engine is bad.
