Suspected cause
If the fuse is not blown, likely the resistor is bad, this is assuming the high speed operation is fine (turn on the A/C).

I was un-able to have them kick into high while just sitting, idle in the driveway (what does that tell you about Seattle summer temps) but on Medium speed I have only one fan running - side opposite my "bump"

Coverage and how to read this overview
Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

(not to snivel, but I know it doesnt work now, and I am not at all certain it worked before)
I was going to piggy back this question, but I need to know quickly as my car goes in tomorrow for the estimate on the little fender bender I was in....
when the fans are on medium speed - do both side run?
I was un-able to have them kick into high while just sitting, idle in the driveway (what does that tell you about Seattle summer temps) but on Medium speed I have only one fan running - side opposite my "bump"
Thanks for quick replies.....
I get a Ford Fu***** to drive to work tomorrow!
ok. I hit some road debris with my Boxster and busted driver's side radiator. Radiator replaced. Fan suspect. (Imprint of fan where it spun against radiator so you know fan took a bit of a beating.)
Tech wanted to replace fan. I reminded him with PST2 (now PWIS) he can command one or both fans come on. He did and found both fans ok. Left original fan in car and that was about a zillion miles back and fan still ok.
Sincerely,
Macster.
Fans are wired to run at the same time regardless of speed. If the fuse is not blown, likely the resistor is bad, this is assuming the high speed operation is fine (turn on the A/C). You MAY be able to get your hands on a resistor separately -I wasn't able to a few months ago- otherwise you can swap the whole fan over. I do have one for sale if you decide to go that route.
UFFF - $100 for the resistor...(996.616.101.00 right) how do you check if thats what's bad?
the car is not here so I cant check the fuses... but shouldn't there be one fuse for both fans?
AND - this is the side that was hit... any chance these are related? (not to snivel, but I know it doesnt work now, and I am not at all certain it worked before)
I believe there's 4 relays total. From my experience it's usually the resistor though, especially if the fans come on at high speed (which bypasses the resistor). I think I'm only asking $100 for the fan w/the resistor. If you get just the resistor, you'll need to wire it in btw.
Anyway, you can unplug the fan and try energizing it from it's plug. If it comes on at high speed, but not at low speed, you need the resistor. If it doesn't come on at all, you need the motor.
OK - link to fan mod??
I checked and the drivers works on high (had to pull over when it kicked in) NOT on low... is that the resistor? and does the fan mod eliminate the need for 2 resistors?
so the fan is not working for sure on low... it works on high... the guys at the shop said they will have a look at it tomorrow
BTW - I dropped off the GT2 hood and am having it fitted up and the front clip re-done. I feel bad because the body guys could "tell" right away the car has a cheap paint job on the front (PO) but they should be able to get it back looking good and have it done right this time - (not that it will effect my re-sale, but its good having nice paint - sucks the PO put on a cheap one!!
now you can say you have GT2 parts on your car..... BTW... here is the fan mod you asked earlier.
The VF system comes with a 3rd radiator and intercooler. Doing my fan mod for both the front radiator and engine compartment will keep your engine cool at the track as well as reduce your intake temperatures substantially. Make sure the air is properly purged out of the intercooler system. If this is a track only car, yank the thermostat out of the car.
Radiator Fans
Connect a wire to the ground (Pin #85) of the 2 high speed fan relays located on the relay carrier located in the driver’s side foot well. The relays are #20 and #22. Feed this wire to where your switch will be located. Connect the wire to one side of the switch. Connect another wire from the other contact on the switch and then connect the other end of this wire to a chassis ground point.
With key on, this switch will now immediately turn on both radiator fans providing maximum cooling. When you turn the key off, the fans will continue to run for about 5 seconds until the relay shuts down. Your fan operation remains normal when the switch is off.
Engine Compartment Fan
Connect a wire to the ground of the relay located in the relay carrier behind the passenger seat, driver’s side. Relay #8. . Feed this wire to where your switch will be located. I simply fed the wire along the driver’s side of the car and under the door sill. Connect the wire to one side of the switch. Connect another wire from the other contact on the switch and connect the other end of this wire to a chassis ground point.
With key on, this switch will now immediately turn on the fan drawing air into the engine compartment. When you turn the key off, the fan will continue to run for about 5 seconds until the relay shuts down. Your fan operation remains normal when the switch is off. This mod helps keep the engine compartment much cooler when driving around town and is particularly beneficial to any engine that draws its intake air from inside the engine compartment, such as the EVO SC.
If you are adventurous, you can automate the operation of these switches so they will switch off at a specific speed, or operate when vacuum is present only, etc. You can choose any style switch you want and even use Porsche switches (relay required). I simply used 2 toggle switches that I installed in the batwing,

The hood is on.... my bumble bee theme is coming along
will be nice once done, its a way nicer hood than the one I had....it was really rough and had several large dimples from closing on something like a box?
cell - phone crappy pics, but looks like the last one to my eyes!
I am fairly sure it is lighter, I will try and get a weight next time I am down there...
Also I am having a ""poor little ole me" episode so if anyone wants to whack me up side the head i would appreciate it. The front clip is off now and we have had a look inside - now I have known for over a year that there was issues with the front end and with very little effort the body guys pointed out several - the car had been smacked pretty hard up on the drivers front and now I see some of the remains and some of the less than perfect repairs...I am sick....
no.... a differant sick this time
I am going out to enjoy the rest of the day with the kids and try to forget about it, put a positive light on the task, and move forward - with several beers !
waaa - this takes a while....the insurance co will come back and have a look tomorrow - meanwhile the nicest weather ever recorded in Seattle and I am driving a POS rental car
^^^ Gorgeous chick, Redridge! Is she Vietnamese?
I think this is a way better 'engine-cooling' thread than the "Cooler Thermostat" one......even though Ed's radiator fan issues obviously run in the higher temperatures!
Hey Ed.
Good luck with the insurance company (hopefully today). So, is part of the problem former damage that's has been found, or is it that the damage from the current fender-bender is more extensive than you thought?
James
so I talked to the body shop... they said 2 more weeks - I will be $1500 out of pocket when all is said and done. Not bad for a complete nose make over and replacing the hood. The time is killing me though.
Insurance is offering me $300 for my body injury claim... I went to the Dr and had a check up afterwards. I dont feel anything so I am sure I am OK.... but what about lost time and missed events and time spent messing around with the insurance co and stuff.... should there be any compensation for that??
opinions welcomed
I am bummed out... missing this weekends autocross
With the interest for extending the longevity of this post... May I ask where are the radiator fans located... and while we are at it where are the radiators located actually, and how many?
Both the fans and the radiators are located in the front of the car. Some cars came with (and other were modded) to add an additional radiator called a 3rd radiator which would be smack dab in the front of the car under the licence plate
pleas note how the first image makes one think of the 2 radiator set up, the second and third image show how much better a 3rd radiator is....
a concealed third radiator is very nice set up as well.... Its there, but it doesnt shout out "look at me"
those who are good with these will know that its there without the need for proof
Well how forgetfull of me, yes there is a small fan attached to the rear deck lid (and if you are like me, you think a small fan in the rear is plenty)
this is normally under cover as seen in this pic -
Good point!
So with this in mind I understand that air-cooled vehicles actually employ/have an oil radiator. So from the collective knowledge base here, can anyone explain (show an example perhaps) how these work and if they also use a cooling fan?
And BTW thank you for educating me on the difference between 2 and 3 radiator configurations. I have gained a new perspective on that!
