Hello !

I was checking my GTA 5.7 and found a problem :
cable broken, it was burnt... see A.
this is possible the sensor which is missing the connection
now.

see the pics !

How do you call this sensor?
i had removed this thing and coolant was coming out of it...
is this a temp sensor ??

I need new one and the whole cable with hose too.
where can i get it ?

and one more thing, code 34 is flashing suddenly..
is this the reason of this error code ?

 

yes that is the temp sensor which has a single yellow wire to it and goes to the computer.

 

please tell me more,
what is this temp doing ?
i thought there is only 1 temp sensor
i m reading the temp stats in the interior, its displaying correctly.
then why is there an second temp ?

is this for the dual fan switch ? or
and this is possible giving the error code 34 ?

can someone please make also a pic like this ?
then i know how its looks before..

and where can i get it ??

 

ok that sensor controls the fan throuth the computer however i,m sure you have a duel fan being a 5.7 this controls the fan motor also you may have another one on the thromstate housing not knowing the year of the vehicle. you can buy one from jeg or summit and with a new connector just know what temp you need due to your thermostat this is a cooling fan temp switch

 

my fault this switch does not go to the computer but does control the cooling fans

 

Yeah it's just a fan switch.

 

Looks like the cooling fan switch.
rather usless in a dual fan setup but, still nice to have hooked up.
the harness wire should be grey iirc.
there are no yellow wires in the fan circuit for any year that I know of but, that (me knowing) doesn't mean much

 

Thanks a lot boys !
thirdgen.org is really useful !!

i will order the parts now..
i m planning to buy a hypertech coolant switch
180 degree of 200 on, i ve thermostat 180 installed

 

Good call on the fan switch. Before you order, search fan switches on the cooling forum, there are some less expensive alternates available and ALOT of different temp. options.

 

give me an example, i already tried the search function

There's alot of options! Personally, I run a 730 ECM so I just program what temp I want my fan on/off and plugged the hole.

 

yes but one thing i don't understand...
why have this 2 cables ? red and black ?
i thought the pigtail was only using one wire??


and this ::

 

its should be something like this ...
this will fit my engine..

 

You'll have to ask on the cooling forum.

I would *guess* that the black is ground and not needed since the unit should ground itself through the casing to the heads. I've no experience with fan switches though.

 

yeah, i think that too.. thanks a lot !
