First we must be sure that the power is reaching the fan ,disconnect the wires from the switch .run a wire from the positivefanwire direct to positive terminal on battery ,do the same onthe negativeside,and the fan should run if there is nothing wrong with it. if it doesnt run then thatis the problem, if ok then connect wires back to swich, before getting too serious turn on ignition, with a test light check that there is current at the relay ,at the switch and at the power in to the relayfrom the mainpower supply.there should be afuse that protects all these things some where ,and thhe more i think on it the more ifeel that is where we should be looking,i`ll wait on you but remember ,the problem doesn`t have to be big to stop things working

    did you replce the fan itself? did you run a independant wire like i sggested it is an expensive and foolish way to just replacing things until you fin ally have changed everthingin the car .you need to fins the cause ,have you found the fuses?

Fans only turn on if idling for 10 minutes or longer and engine temp is at a certain temp. If not working, then either relay or temp sensor is bad.
Make sure thermostat is new as well.

    The fan motors could be burnt out. I would check power running to fan and motor with a voltmeter. You can check fan motor itself with an ohmmeter in the ohm setting.

My honda crv B20B engine of 1996 fails to start at first attempt but will start at third try also drags at rear wheels when turning either side


Maybe the fuel cut relay, or fuel pump? For the dragging, if it is all wheel drive then try replacing the rear differential fluid, make sure it is genuine Honda Dual Pump fluid.

The engine fan won't turn off - it's never happened before - don't have the owners manual or I would try to remove a fuse - help please! I guess I'll disconnect the battery for now.


Hi,
The radiator coolant fan switch is the key here, It'll be mounted either on the radiator or a thermostat housing and controls the cooling fan( large brass unit with 2/3 heavy wires ) ! A replacement will be the best money you ever spent, (OVER HEAT JUST ONCE AND IT'S GAME OVER) . Drain the coolant (and save) when cool/cold and replace thermo rad switch , re fill with saved coolant , check for leaks and bring up to normal enging temp and observe fan operation.Good Luck

1996 Honda Odyssey engine cooling fan stays on.


I don't thing there is a short there is radiator fan switch that control these fan, it works off of heat. There is also a fan relay that control look in fuse box inside the hood for fan relay and make sure its NOT stuck , if it isn't then its the fan switch.This switch may be bad and cause the fan to turn on. Replace radiator fan switch located on water outlet on engine and this should solve your problem. A

01 jetta overheating on the highway


The most likely cause of this is the fan not kicking on... and the best place to start looking is the fuse for the rad fan (under the dash). If this is good check radiator thermo-switch... Observe the engine as it comes up to operating temp... if the fan does not kick on by about 200 degrees, disconnect the terminals at the switch and connect them together briefly. If the fan comes on then the switch is faulty, if not then suspect the cooling fan relay. If the fan runs normally but vehicle still overheats, the next thing to check is the T-stat. Feel the upper hose when at operating temp... it should be warm... if not remove the T-stat and reassemble... if the problem goes away it was your T-stat, if not it is either a bad pump, or a restricted (clogged) radiator. If the pump is not noisy or weeping coolant, it's probably OK... Hope this helps...;-)

OVER HEATING


In the fan circuit...You have a temp switch screwed on the radiator, a fuze and a relay in the fuze box plus a fan.  Swap the relay with another relay, replace the fuze.  The other fan should come on when the a/c is turned on.  If you fix the fans and it still overheats, you may have a BLOWN HEAD GASKET.  ALSO ARE YOU BLEEDING THE AIR FROM THE SYSTEM?  DO YOU SMELL EXHAUST IN THE COOLANT?

Thermostat replacement in 1985. Need diagram or very explicit intructions.


The thermostat housing is on the left side of the engine at the front, bolted to the side of the block with two bolts - top and bottom of the housing. Obviously, before starting, let engine cool and release pressure from system, drain out coolant (about half) so little is lost when stat housing removed. If coolant is old, this is a good time to replace it. When replacing the stat, get a SAAB stat, as it's a three stage stat, not a two stage (open and closed) as are most after market stats. If you car runs hot in traffic or hot days, consider the low temp stat (and rad fan thermo switch also) to extend engine life. Tighten the bolts to 13 ft-lb. Refill and bleed out any air. Hope this helps, give a "thumbs up" if it does; thanks Saabreur
