GS rad and shroud install problemo
 

Finally made my fan shroud yesterday 40$ for a piece of lexan 1/4" thick and 16/26". Got it all in wired up the fans to stock fan harness took it for a boot fans go on at 180. I then noticed they never shut off. I look under the hood the wire for the thermo-switch for the fans got blown off or something. I thought that switch was to make the fans come on? Does it make them go off to? My temp guage was staying at 190 even though the fans were on for about 10min while i was driving. So im asking is it that since its broken my car wont cool down and the fans wont go off? And if i get a 160deg thermostat will my temps be cooler? Thanks Mike

Here are some pics

switch isnt actually like that i rigged it so i could connect it but no luck.

Does the MS run the fans off the switch like the stock ECU?

On the stock ECU the fans get turned on by the switch and if the wire is off the switch they don't turn on. Did you have your AC on?? That turns on the fans and keeps them on.

Going to a lower temp thermostat will only circulate the water sooner. You will still get as hot it will just take longer to get there and if you need heat in the winter it will affect the heater.

Umm i have no clue about that for the MS running the fans, anyone know can they chime in. I dont have A/C. I dont drive in the winter so i dont need heat. And is 190deg a normal temp or is it to high cause my switch is fucked cause usually it cools down then goes back up and the fans go off. How do i fix it do i have to set something on the MS?

Does anyone know what to do? Do i have to wire my fans into the output on the MS my cars not cooling down and the fans are not shutting off...

What type of MS are you running? If it's a standalone configuration, you need to mod the MS to control fans. If it's parallel, then the stock ecu should still be controlling the fans. If it's a MSPNP from DIYAT, it should control the fans no problem.

Its a MS PNP from DIYAT, but it does control them but they never turn off...it reaches 180 turns on, they stay on and my coolant temp still stays the same. And my thermo switch isnt even hooked up and they still turn on but never turn off.

You need to seal the sides of the fan shroud.get some weather stripping and seal the gaps around the entire shroud.

Alright thanks. But why do the fans still come on if the thermo-switch isnt connected?

Because you probably don't have them hooked up correctly with MS. Post a screen shot of the settings your running for fan control, and explain how you wired them up in DETAIL. Nobody here knows how you set this up but YOU.

I cut the harness from the stock fan and connected the 2 10 inch fans to it. Heres a pic i made on paint not that great Attachment 213623

but you get the idea, for the MS part i haven't touched any settings for fan control what ever came with the MS i left the only things i touched on MS were timing and req fuel and some tuning thats it.

You say you don't have A/C but did you?? Why I'm asking is did you hook both fans up to the main fan harness. You diagram shows them hooked up to one lug, fine, but was it the main fan plug?

No i did not have A/C before i just wanted to rad fans so it could cool off faster. And yes i do have both hooked up to the main harness and yes it is the main fan plug.

hopefully these pics help you out

You still didn't post your MS settings.

So the fans come on at 180* per megatune guage but they never go off? Try puting it to 200*F or so. You need to see what the settings are.

What settings? Where do i go to get them? The shift light-fan-output thing? Im nood at MS help me out here where i find these settings.

Sorry, I don't know MSI, I use MS II. I go to MT, then Exteded, then Output Port. Their, I can select different outputs to be controlled by various inputs, such as fans controlled by coolant temp.

Alright i think i know what your talking about...if this is it here it is:

one of those i think it is? And do you think its not cooling down cause its not sealed?

Damnit, answer my questions. Do the fans come on at 180 or do they come on all the time? I already asked you this. Right now, your screen shot shows they come on at 215 and have to go down to 210 (hence the 5*F hysteria) to shut off. That means they 'should' come on at 215, off at 210, and repeat. Do they run all the time as in key on the fans are on? Jeezus, answer the questions. Do they run all the time? Ok, I asked the same thing 3 times, maybe you'll get it this time.

Lmao alright they come on at 180. And the thermo switch isnt hooked up and my temps dont even go down when there on.

Well, you have them set to come on at 215 by the pic, so somethings wrong. If MS is running fan control then that thermo switch has no effect. Why don't you try turning the car on when it's cold and varying the setting on fan control and verify you can make them come on and off by changing the on/off temp. For example, put it to 0*F and 1000*F, they should go on and off. Turn your brain on and think, troubleshoot, and eliminate possible problems until you discover the error.

Yes i know i was fooling around with that and they were going off and on didnt know why. And so thats why the thermo switch is pointless i see. Soo what would i have to set them at then, is it not cooling off cause my fan shroud isnt sealed and its pulling air from anywhere?

I don't know, but you should definitely try sealing the shroud. Oh, and please TRY to use a little bit better grammar. I hate being a grammar Nazi, and yours isn't terrible, just saying I had to read it twice to understand it.

Sorry i just type so fast sometimes and forget to proof read before i post. Alright im going to use this tape,
http://www.constrictors.com/images/Info/TempProbe.jpg
I believe its called heat tape, it looks like tinfoil and is very sticky :). Its used around your furnace pipes to hold them together and good for heat hence the name, and i have lots of it. So im going to give that a shot and tell you how it works out.

That's called duct tape. Anyway, I would suggest using some weather stripping myself to seal it up.

Ok so i used weather stripping but it was round not rectangular so it sealed better then i put that tape over it. Went for a drive fans went on at 180deg but there always on and the car temp stays at 184deg all the time says megatune is this normal? Or should it be cooling down fans go off then come back on or stay at that current temperature, cause i dont want my car overheating.

this does not sound right?
your fans should come on when MS tells them to come on, if your ms is set to turn fans on at 215 and they are coming on at 180, then you may have a problem...
however, think your problem is that your MS looks like it is set to turn fans on at 180 and off at 155, that's not good, your car will never be at 155 while driving, that is way too cold...
Set fans on at 207, of at 197 and see how that goes for ya...(or you can do on at 197 off at 187)
do that, report back

Alright thats what i was thinking, il bbs lol

No go changed it to what you said...fans are still coming on at 180deg. Where it says fan on and fan off temperature i think thats if you wire it to the MS with the pins.
Attachment 213595
And i changed it to inverted on this one on the bottom and they went off...fooled around with the numbers never turned on put it back to normal fooled around with the numbers again and they are still coming on at 180deg:vash:

Shit, I dunno. Why the hell would MS turn them on sooner? Turn fan control off and go for a ride and see if they still come on a 180. Do you still have the stock ecu? Is the stock coolant sensor thing maybe cutting in and turning them on? Your settings look fine, you must have some wiring wrong or something.

perhaps a sticking relay?

Did that turned them off still come on lol. Nope no stock ecu just the MSPNP. Um the thermo-switch(stock coolant sensor) isnt even hooked up and they still come on and when it is they still come on. And i believe someone said that when you use MS its not even used to control the fans to come on. Pic again of how there hooked up

i need this fixed insurance is going to be on this weekend!!!:mad:

when you got your MSPnP, it came with instructions, no?
if it did, did you follow instructions on how to wire up the fans, did you even install it yourself?
Did your Stock fan come on at 180, or do you even know this.
Describe in proper english the series of events that lead to the problem.
ex: install MS, tune, all good, install fans, problem...etc.

Here's a brillant idea. I dunno where I come up with this shit:

Email Matt or Jerry and ask them exactly what you change to alter the temp that switches the cooling fans on.

duh duhrer

Read, people. Or search. Output 2 controls the fan. On-Off Limit controls the switch temp. Notice that it says, right next to that, in parenthesis, that the value is deg F +40...meaning that a value of 215 means temp switchpoint is 175.

The hysteresis value controls the time/temp variance for on/off control (so that the fan isn't constantly switching on/off right at the switch point).

This is all explained in the MSPNP manual, as well as in previous posts on this forum. READ!

Besides, 180°F is just barely warmed up. Take Zapac's advice and set it for ~200 (remember, in stock form, the fan turns on at 207°F...so stop freaking the fuck out).

Okay i put the on-off limit to 247 cause you said its -40 so that means they go on at 207deg right, and then i put the off hysteresis to 50 so that means they turn off at 197. Am i correct?

OMG, he said read. Do what he said. It would be the best thing you could possibly do. I know what you need to do now, I read.

I did fucking read cant you just answer the god dam question yes or no is it that hard...
edit:my manual got burnt up :giggle:

We should build a corral for you people. Round you up and beat you with the fucking documentation!

Congrats, you are the second person on my ignore.

Sort of. You're ok on the 247, but I'd go with more like 240 to start with. But 50 on the hysteresis is ridiculous. Leave it at 5. But go test it; at what temp does the fan come on with the changes? Does it decrease temps? If so, what temp do they turn off? Test at idle and at speed...does the temp decrease at idle with the fans alone, or does it take some air movement (car at speed) to get temps low enough for fans to turn off?

But seriously...don't do something because that's what some Joe Blow on the interweb said. Read what they said, understand how/why, and verify against the sources at your disposal. Then do something because you actually understand what you're doing.

This should be shown on the google homepage to let everyone know what the proper procedure for using internet advice is. :bigtu::bigtu:

Alright thanks for all the info, and the hottest it got was 187 so it really never got hot enough for me to check if they went on cause i only drove around the block cause my insurance doesn't start till Friday :eek5:, but when it does i will check from there thank you once again. And i really dont give a shit if im on your ignore list i already have a fan club...:fawk:
