SOURCE: cooling fan on a8v-vm se

The whole colling speed is set properly within the computer so I wouldn't go adjusting that. You could get a different fan similar to the one thats in it, that may be a bit quiter.

Take it to the computer shop and show him them one you thats in it, that is on condition that you are confident about taking it out and putting on a new one in its place.

Make sure you are grounded when you open the computer and wear an ESD (Electo Static Discharge) strap or something. Especially when you are going near the motherboard.

Honda generator eu3000is Not getting power to carb in order to meter fuel

After reading about Honda's Eco Throttle system available on inverter generators it seems it is not a fuel metering system but a computer controlled speed regulator or basically an electronic throttle.
Because the engine of an inverter generator doesn't need to run at a constant high speed to produce the correct 50 or 60 Hz output this generator can run at slower speeds when the load is light. The electronic throttle is the means to make it happen - operated by the computer.

The throttle is probably operated by a stepper motor and the power supplied to it likely to be in digital form. I suggest you try and gain a more full account of how the system works before you delve deeper.

When I've stopped and removed the key both cooling fans run and it flattens the battery. They run at full speed for a bit and then reduce speed and speed up and down. It s a VW Touran FSI 2005 model

Try unplugging the cooling fan relays. if the fans stop running, replace the relays. The fan relays are located in the plastic box under the hood, near the battery on top of inner fender well. The box lid has fuse and relay description printed on it.

My ac is not working I have a Chevy Tahoe 2005 the fans won't turn on either .

Hi Maria , The A/C system wouldn't keep the fans from running but none working cooling fans will keep the A/C from working ! This is a fairly complex system if your not familiar with this sort of thing ! I will add the description from the factory service manual.
Cooling Fan Control - Two Fan System
The engine cooling fan system consists of 2 electrical cooling fans and 3 fan relays. The relays are arranged in a series/parallel configuration that allows the powertrain control module (PCM) to operate both fans together at low or high speeds. The cooling fans and fan relays receive battery positive voltage from the underhood fuse block.
During low speed operation, the PCM supplies the ground path for the low speed fan relay through the low speed cooling fan relay control circuit. This energizes the low speed fan relay coil, closes the relay contacts, and supplies battery positive voltage from the low fan fuse through the cooling fan motor supply voltage circuit to the left cooling fan. The ground path for the left cooling fan is through the cooling fan s/p relay and the right cooling fan. The result is a series circuit with both fans running at low speed.
During high speed operation the PCM supplies the ground path for the low speed fan relay through the low speed cooling fan relay control circuit. After a 3 second delay, the PCM supplies a ground path for the high speed fan relay and the cooling fan s/p relay through the high speed cooling fan relay control circuit. This energizes the cooling fan s/p relay coil, closes the relay contacts, and provides a ground path for the left cooling fan. At the same time the high speed fan relay coil is energized closing the relay contacts and provides battery positive voltage from the high fan fuse on the cooling fan motor supply voltage circuit to the right cooling fan. During high speed fan operation, both engine cooling fans have there own ground path. The result is a parallel circuit with both fans running at high speed.
Do you have a check engine light lit ? The thing to do would have it check at the dealer or a ASE certified repair facility ! They could hook up a advanced scan tool an diagnose fairly quick ! Or you could find a wiring diagram an try testing with a volt meter yourself ! But watch yourself so you don't short out the PCM - engine computer !

Cause to overheat on tacoma tacoma 1998 2.4 liter

over heating can be from

blocked radiator, blocked radiator core fins, thermostat, collapsing bottom hose , air locks in the cooling system, head gaskets/cracked heads problems, low water level in the radiator, faulty viscous fan hub ( if fitted to fan), problem in the ecm control of the vehicle, Running too lean or over fuelling, dragging brakes, overloading/over speeding, radiator cap faulty
There can be one single fault ( head gasket ) or a combination of faults

Mini Cooper temperature gauge goes to red zone when idle

check coolant level could be too low allowing air in the cooling system causing air pocket in engine around the engine coolant sensor.coolant sensor needs to be in hot coolant so it will cause the cooling fan to come on at a set temperature.make sure coolant correct level and the coolant level in the cooling overflow jug should be at full cold mark.the cooling overflow jug should never be empty,if you see empty cooling overflow jug air got in the cooling system so make sure when engine cold every time raise hood make sure cooling overflow jug coolant level at full cold mark.if jug stay empty you have cooling replace radiator cap,if coolant level all good,i would replace the engine coolant temperature and thermostat.when your car come to a long stop or driving along long line of slow moving traffic the engine coolant blower motor should running if not have vechicle code scan for faulty coolant fan motor control module.or ecm problems.

Power steering pump on my 2001 mini one stays on when the ignithion is turned off

It is not your ps pump that is staying on, it is the ps pump COOLING FAN located below the pump. On 2001-05 Minis, this fan is wired directly into the wiring of the main radiator cooling fan, which has two speeds, low and high. When the engine compartment temperature reaches a certain level, the main radiator fan is supposed to come on, and since the ps cooling fan is also wired into that, it is supposed to also come on. But, that low fan speed is achieved by routing power to a resistor, located at the top back of the radiator on passenger side, that cuts the power down. This resistor is highly prone to corrosion and failure. When that happens, neither the main radiator cooling fan nor the ps pump cooling fan can come on UNTIL the engine compartment temperature reaches an alarming level, which switches through a relay power directly to the fans, by-passing the resistor. By then both fans are attempting to bring the temperature back down to a safe level. Then, if you turn your engine off before the temperature reaches the lower threshold so that the fans are still running, the ps pump cooling fan will just keep right on running, as there will be no relay signal given to turn it off, and your battery will be drained.
To fix this, the resistor either needs to be replaced, or, the resistor can simply be removed and the contacts jumped. This last fix will mean that when the lower temperature threshold is reached, the main radiator cooling fan will come on at full speed, and the ps pump cooling fan will also come on. After my ps pump failed due to fan failure, I did this to my '03 Mini, and have run it for years this way. No more ps pump problems. You do need to make sure you keep the fan clear of debris and freely turning, or you could have bigger problems, like a fire, since the wires will get very hot sending power to the fan motor when the fan is bound up with the motor not turning. A blown fuse will often be the first indication of a fan bound up.

Over heats after 10 minutes running. I have taken rad out and ran water through it, put it back in and when it is running the bottom hose collapses.

Is the cooling fan running? If so, drain the radiator with the heater control set to hot. Install a new thermostat, and fill the system with a 50/50 mix of antifreeze and distilled water. Bleed all air from the system by using bleeder screws if equipped, and by starting the engine with the radiator cap off radiator full. Watch for escaping air bubbles and keep the radiator full. When you see no more air escaping put the cap back on. If the fan is not running then that is your problem. Turn the A/C on and the fan should run continuously. If it does not the fan motor is more than likely bad. Check the fuse for the fan. If it is good, Apply 12 volts directly to the fan motor to check it. If it runs then replace the thermal relay.

Running hot at higher speeds.(6 cyl) Does not have a full shroud around radiator. Does it require one?

The shroud around the radiator fan mainly assists cooling at lower road speeds - it increases the efficiency of the cooling fan/s.
At higher road speeds the increased airflow due to vehicle speed makes the fan and shroud less important in that circumstance.

Running hot at higher roadspeeds can be caused by either engine mechanical fault (blown headgasket etc) or defective cooling system:-
Check for combustion gas bubbles in coolant reservoir - and ensure engine has no other mechanical running problems.

Check cooling system as follows:-
1) Faulty thermostat,
2) Blocked radiator air flow due obstruction such as grasshoppers or other insects,
3) Blocked radiator core (internal) by sludge/scale etc.
4) Collapsing radiator hose on intake side of waterpump (due to softened hose),
5) Cooling system not properly filled with coolant due air locks in the system - bleed off any air (as manufacturer specifies) during re-fill with coolant and ensure flow to heater core is enabled.

Running at idle speed

1) Check the "Economy Throttle" setting (or some similar verbage). Inverter types dont have to run full speed to produce full voltage.

2) Apply a load. These magically accellerate and decellerate according to load conditions.

Hope this helps,

1994 9000C Runs hot

Could be the fan thermoswitch. The thermoswitch, if there is one*, is located on the lower portion of the radiator just in front of the turbo outlet pipe. Here is a picture.
You may also have one of the fan relays failing. (On some cars, there were two relays, one for low speed and one for high). Here is a picture.
For general diagnostics of the cooling system, go here.
2 stage cooling fan wiring diagram here.
This also will tell you where to find other components to check, like the fan speed resistor, and provide other diagnostic checks.
