My Answer is. I would like to speak with RIP. I I have and issues I have been testing one thing at a time with a fan issue. Your explanation to the other guy gave me almost all I need. Would appreciate a convo. I am a professional auto painter . Trying to help a friend for free just because. I have been getting diagnostics done after every fruitless parts change. Lol.

Op
why not post symptoms first and not a barrage of parts.
must we decode that to a symptom,. kinda hard right.

I will not guess. what is wrong, nor what is not working on your car. now what fans you are talking about, up to 4 fans on cars.

cab blower fan (wild guess blower is ok) and so is HVAC, ?
radiator fans
Condenser fan.

my wild guess to , engine over heats?????????
if yes, the scan it first. no not last FIRST.
it dont work like you think its not a 1988 Samurai.
sorry,
on modern cars, they got smarter, the engine goes
gee the PCM knows water temp why have a fan temp regulator.
hark , now it dont. (saves cash on useless parts)
but has a relay , (well until you have my car and the relay is now 100% electronic, called a huge transistor)
we've used this tech in industry for years, but car makers just learning how still.
i digress. but evolution and history helps diagnosis.
what is there?

Ill look for you, ive posted this 100s of times
the book is 4 bucks to see online. the real deal
lets look now.
XL-7 (the dash matters big time)
answering for , overheats engine, and fans on RAD dead.
(some are staged, PCM brains... now. and also chain ops based on if A/C is on or not) facts.
first I see 2 fans... ok.
the next page shows nice block diagram of the fan system
yup, NOT Simple.

ill post those words for you.
"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 engine control module (ECM) to operate both fans together at low or high speeds. The cooling fans receive positive voltage from the cooling fan relays which receive battery positive voltage from the underhood fuse block.
During low speed operation, the ECM supplies the ground path for the low speed cooling fan relay which is fan 1 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 fan 1 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 series/parallel relay which is fan 2 relay, and the right cooling fan. The result is a series circuit with both fans running at low speed.
During high speed operation the ECM supplies the ground path for the low speed fan relay through the low speed cooling fan relay control circuit. The ECM grounds the high speed fan relay, which is fan 3 relay, and the series/parallel relay, which is fan 2 relay through the high speed cooling fan relay control circuit. This energizes the series/parallel 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 fan 2 fuse 1 on the cooling fan motor supply voltage circuit to the right cooling fan. During high speed fan operation, both engine cooling fans have their own ground path. The result is a parallel circuit with both fans running at high speed.
When the request for fan activation is withdrawn, the fan may not turn OFF until the ignition switch is moved to the OFF position or the vehicle speed exceeds approximately 16 km/h (10 mph). This is to prevent a fan from cycling ON and OFF excessively at idle.
end quote.

i bet you didnt scan it , like 99.9 % of all posters here dont.

Diagnostic Fault Information

is the ECT showing overheat, yes no?
if yes, it must operate a fan or 2.
the book even covers all tests for fans dead, in a large truth table.
both the FSM and alldata.com have that, its no secret ,its published in 4 major places.

lets back up
if the engine coolant is low (no that side tank the engine and rad)
the ECT will lie. if that happens the fans may not come one
that is because the ECT is useless measuring air, for water.
that water must touch ECT for ECT to work.
this is FIRST
then scan the ECT does it show overheating, IT must if it IS overheating. fix that next if it lies to you,(IR gun in hand)

The system has staged fans.
i cant find the trip points in my crappyy online pages.
but is like 225f then 250f trips. is my guess...
about. if the engine over heats, check fuses first then scan it.
it will simply tell you why its bad.
eg, fan1 output dead.
or if you hot wire a fan and its dead, then it is.
(only on cars with non modulated fans,,hot wire them,else not.)

now the link to the 4 buck real book.
the non dash XL7 (my guess) you this pick yourself... cant see car.
https://suzukipitstopplus.com/Products/10182-2007-xl7-service-manual.aspx

this is how it really works
the ECU has software that decide trip points for fans.
hard coded, this is. based on how hot it is and if A/C is on not.
its way smarter than 1988 and better.
the DTC errors can see an open line, shorted to ground or stuck 12v.(runs all time error)
(tells you relay is good or not)

    added the schematic, as you can see the PCM grounds the coils in allcase to turn on fans
    but note the series center relay
    if one fan is open , some modes will be dead 2 fans. due to the series mode.
    tricky no?

    this magic saves fuel... btw.

I doubt the coolant temp. sensor is bad , the ECM - engine control module turns the fans on . Do you have a check engine light lit ,does the vehicle run alright , shift good ? The coolant temp. sensor is an input to the engine control module , the control module uses the temp. sensor for fuel control ,according to temperature .
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 engine control module (ECM) to operate both fans together at low or high speeds. The cooling fans receive positive voltage from the cooling fan relays which receive battery positive voltage from the underhood fuse block.
During low speed operation, the ECM supplies the ground path for the low speed cooling fan relay which is fan 1 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 fan 1 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 series/parallel relay which is fan 2 relay, and the right cooling fan. The result is a series circuit with both fans running at low speed.
During high speed operation the ECM supplies the ground path for the low speed fan relay through the low speed cooling fan relay control circuit.

When you turn on the A/C the fans should come on , do they ? What is the temperature gauge showing ? overheating ?
Did you replace all the fuse's relay's etc... I suggest you take it to a ASE certified professional technician . code have DTC'S diagnostic trouble codes stored !

    or , check fuses, check the relay.
    then check fans.(test them with a battery)
    if all those are ok, scanning is mandatory.

  • Anonymous Aug 28, 2015

    ps this car even shows on dash, im overheating.
    too bad all symptoms not stated.
    the fans can fail lots of way.
    and are tested 3 ways. to get that data.

Where is sensor for radiator fan located

this is covered 100% in the FSM.
but first youd have to be on the right engine page, and was not stated by you.
4L or 4.7L ?
you could read all this for free., (posted 100 times)
http://www.jeep4x4center.com/knowledge-base/index.htm?utm_source=cj#service

the schematic is 8w-42 (chapter 8w is electrics)
see "wiring AIR-------" page
page 9 .
42-9 4.0L only.
you see what.? a fuse F10 (blown)
you see the fan controller
and the fan relay
and the fan.
and THE PCM
the PCM decide when the fan is on, or off.
so..... if the thermostat is stuck open, the ECT shows, low heat
and the fan never turns on.
so did you do the FSM fan test? in the book.?
it shows how to do that. it has you overheat the engine on purpose
(idling it too long)

the 4.7L is totally different so, no engine stated, all answer will be wrong.

Cooling fans are not coming on, what could be the problem?

Either the temp sensor is bad, or the relay is bad. or the fan motor is bad. Or you have a blown fuse.
Look for fuse first.... To test if fan motor is bad disconnect the connector to the fan and jumper it to the battery.if it spins it's good. the other two. use a component locator to find their location and replace. they are inexpensive. Temp sensor is in the cooling circuit (radiator...maybe next to thermostat) the relay will be in a fuse box under the hood.

Hi i have changed the head gasket on my vw polo and now it is overheating on every journey the fan doesnt seem to come on any ideas what it could be as i have put new temperature sensors and thermostat and...

Hi Marie.

Test if there is voltage to fan motor with engine hot (use a test light or a Voltmeter). If there is 12VDC to fan motor and motor does not turn, then the fan must be replaced. An alternative way to test the fan would be energizing the motor by connecting it to 12VDC. If fan does not run when motor is energized, then the fan is defective.

If fan does not get power fuse, fan relay, thermostat and wiring must be tested. If you have already replaced thermostat, test the rest.

Check the fan fuse first. Most VW use a 30 Amp fuse located in the fuse plate. Refer to the car owners manual for fuse location. Depending on the year of your Polo there is a Coolant Fan Control Relay on the main relay panel. If the relay is good it must power the fan when the engine is hot. Before going for the relay check that two of the relay's contacts are getting power. If there is no power to the relay and fuse is good it means that there is a wiring problem.

Regards.

Check fuse. If it is good, follow the fan wiring until you get to the relay. You can test relay with a multi-tester. Between the relay, the temps sensor, and the fan motor, are all the reasons a fan won't come on

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.
