SOURCE: I have a 2005 Jetta 2.5 and it seems like one fan runs to fast

One fan should run when engine is running. Other fan should run when AC is on.

SOURCE: Cooling fans and AC on 2000 Jetta 2.0 litre GLS - not working!

worked on one of these last week as well done the door locks and gearchange.Cant remember but look around the rad area for a reostat pack ,also check the earth on the fans and for a feed as that will give you a clue what could be wrong ,but the fan should come on with the AC so something is amiss .My favourite is to run a feed from the battery and then try pushing it behind the positive ,and then do the same with the earth,Cant live without the AC here in alicante spain ,its still about 28 outside now and its 22.11 ,try it out then get back to me if you cant sort it because i have to go now to pick er indoors up from work

SOURCE: cooling fans in op until engine is shut down

Check out clarks-garage.com he has a complete troubleshooting guide for your cooling system along with a schematic. In short, check the low speed resistor on the firewall. Should be around one ohm.

SOURCE: Why does the fan keep running on 2005 jetta after turning off

You are talking about the thermo electric cooling fan, its operation is independent of the car's electical system. It is switched on and off by the engine temperature. When you park, the engine heat soaks upward to heat the thermostat turning the fan on. It will run until the engine cools down and the thermostat switches it off. Quite normal operation.

What is the max. temp. for 2004 4x4 trailblazer

Depends.
A normal cooling system runs between 195 degrees when the thermostat opens, to 230 degrees when the cooling fan kicks on.
If you are experiencing air temps over 90 degrees, the cooling system could run at 210 or higher.
Idling and moving make a difference too.

Engine fans come while driving then after a little while they go off and that happen every so often.

This should be normal operation of the fans they do not run all the time as most people think as the engine temperature increases the fans will come on to help cool down the engine once the temperature decreases then the fans will cut off and it will continue to cycle that way there is nothing wrong with that its normal. You will notice however that when you turn on the A/C the fan will turn on and stay on till you turn off the A/C this is also normal some vehicle have two fans one for the A/C the other for engine cooling unless your engine is getting too hot then they will both come on but normally one is for the engine cooling the other for the condenser A/C and this one will only come on when the A/C is running.

I have a 2002 Dodge Ram Quad Cab 4x4. The a/c runs great as long as the truck is moving, but as soon as you come to a stop it starts blowing warm air. Please help.

Generally if the a/c works fine at highway speeds but kicks out or slowly begins to blow warmer and warmer air as the vehicle is driven at slow speeds or is stopped the a/c condensor cooling fan is usually at fault. At highway speeds there is enough air being forced through the radiator, condenser, and oil coolers to keep everything working and cool but when the vehicle is moving slowly or is parked the electric and mechanical cooling fans have to be working to pull enough air through to keep things working. If the cooling fan isn't working or can't pull enough air through the a/c condensor the system will kick out once the internal pressure reaches a certain point. Once the vehicle is moving again the system can get rid of the heat that it has gathered from the passenger cabin, the pressure drops back to normal and the system cools again. I would start by looking for a blown cooling fan fuse in the fuse panel under the hood. Usually they are 25 amps or larger and run only the cooling fan.

Jetta 2003 2l fault code p2182

P2181 Cooling system performance

Check Thermostat operation & Temp sensor for ECU. CHECK ENGINE CCOLANT TEMP SENSOR IN WATERHOSE, NORMALY A 4 PIN PLUG. ON SENSOR SELF PIN 1&3 OR C&D AT 0 degrees
5000-6500 ohms,60 degrees 530-675 ohms,90 degrees
200-275 degrees

Could also be the cooling fans - I've heard of fixing it by replacing the fan motor and clearing the code as well. The easy fix seems to be the coolant sensor though - I've seen several online threads where owners cleared this code by changing that sensor.

2004 dodge ram is over heating, the thermostat and fan clutch have been replaced.Doesn't(over heat) in cool weather,but will in mod. weather if driven over 70mph or hilly terrain due or increase of rpm,and...

Water pumps can stall out, but do you have air trapped in system.
Had you recently had the system "open" to replace hose, thermostat, temp sensor. Some Ford and GM have a bleeder screw on a high point in cooling system to bleed out trapped air.

Check your trans fluid color. Since the trans cooler is built into radiator (automatics)

IF the engine is overheating the trans CAN overheat
IF the trans is overheating the engine CAN overheat

They share the same cooling source and trans fluid gets hotter than oil, but yet it has a wimpy cooler built into radiator. Maybe add trans oil cooler to system.

Also outside temp affects the cool down rate of the radiator, ie...hot air trying to cool down hot radiator/engine is less effecting than cool air cooling hot radiator/engine

Fanning running

If no engine lights are coming on, and the dealership has diagnosed it normal, I wouldn't worry. Electric fans may stay on even after the car is shut off to help cool the engine. Usually there is a warning in the engine bay stating this.
