cooling gremlin

[my7mgte527]

i got cooling gremlins again... this time the 2 eletric fans are not working. i wired them up to the aux cooling fan . i had to call the dealer for that 1... now the fans dont work and cars is over heating... any ideas of what it could b. im thinking its a eletrical problem but idk if the cooling fans have a relay or a fuse that goes to it... :1zhelp:

Let me get this straight your using main engine e fans that are wired for the tiny a/c fans?

That wont work. They only come on when the a/c is on or your engine is above 210* or so.

Or is it just the 2 small fans dont work and you still have clutch fan. If thats the case those not working is not the problem for overheating.

 

[my7mgte527]

the a/c fan isnt working and the 2 eletric fans r not working either

YA wiring the main cooling fans to the small aux fan that only turns on will not cool the motor unless you have installed a larger fuse and thicker gauge wiring cuz it'll just blow a fuse almost immediately. plus if you get them running you need to make sure they are blowing towards the motor, cuz if you wire them backwards it'll be blowing air the wrong way and cause overheating.

How are the main engine fans wired?

+2^^

You should do some research before doing stuff like this
Your lucky someone didn't install a piece of wire instead of a fuse
This is exactly why most car fires start
Overload the electrical and shit melts

 

[my7mgte527]

they were wired blowing 2 the engine

You blew the relay.
The proper way to run e fans is to wire in a relay to each fan.
In some cases, a 30amp relay is just barely enough for the current draw.
I installed a radiator fan switch in the water elbow, and ran two independent relays off there, each with it's own direct line to the battery.
Problem with that location for the rad switch is that the fans would run for at least five minutes after shutdown, because the fans can't cool the reference(water elbow) coolant.
The proper way to do it is to weld a bung into the radiator itself, and wire the radiator switch at that location. That's why car companies do it that way.
But then I got smart and put a new oem shroud and belt-driven fan on. never had a problem since,

 

[my7mgte527]

what relay is it and where is it located bc im gunna fix it in the am

 

[my7mgte527]

cant find the location of the relay and can any1 post a diy on how to wire this up properly bc im dieing here bc of the heat wave

 

[my7mgte527]

fixed the problem and the relay was good so srry if i was a pain in the but lol

 

[hvyman]

What was the problem?

 

[my7mgte527]

the a/c fan relay had 2 much on it so me and my father decided to rip out the ash tray and run 2 toggle switches for the time being. i kno where is a kit out there ill just have to find it one day but if wana do eletric fans it would be best to find the right kit for it if not then it would be ur best bet o run toggle switches just to make it a simple instal

 

[hvyman]

Can run engine fans on the a/c fan circuit.

What did the ashtray have to do with running toggle switches?
And I think Hvyman was trying to say that you CAN'T run engine fans on the AC relay.
If I recall correctly, the ac fans only come on if the ac is indeed on, OR if you exceed a dangerous temperature- something like 225 degrees or something.

 

[my7mgte527]

no they accually come on as a safty measure i he clutch fan didnt work properly correct me if im wrong though

 

[hvyman]

Yes they come on when the engine is too hot or anytime the a/c is on.

And ya i meant cant.

Can always either refil the clutch fan with new fluid or get a new or good used one. The 1hp gain you get from removing it is lost in amp draws on the alternator.

 

[my7mgte527]

well the fans i have now work fine and i think the engine running 2 hot would b from the blown head gasket or the sylicone stuck in the bottom end by the freeze out blugs but the car runs fine now so im not worried due t the fact im in the process of building a custom 7mgte and planning on making a goal of 900 2 the wheels with the propper tuning of course

 

[jonahs_supra]

do you have a relay or soleniod wired up with the toggle switches?

 

[my7mgte527]

im running 2 30a fuses bc they r on toggle switches for the time being until i can afford the propper kit
