i got my swap done, a 95 LT1 in my 92.
i used the 92 fans.
a couple time the fans didnt come on and i almost overheated.
when i went to the car later, they worked.
since the swap it seemed to run cold, and heater wasnt very warm.
now the fans wont come on at all. what could this be? the switches should be fine, they are new. is there a sending unit on the car that was haywire?

 

check yur wires for shorts and melting becuase of engine heat same thing happened to me

 

alright, ill look into it!
thanks

 

Are you sure the cooling system is bled properly ? Which heater lines did you use.

 

i used the same heater lines that the thirdgen used with that vaccume switch. i hooked it to the water pump tit that is right below it, the one that angles up.

its so wierd. they stopped working over the weekend and didnt run again til yesterday, and now the fans are working and the car seems to be running cold, like they are comming on too soon.

 

Josh, you should be using 4th gen heater lines, at bare minimum the sections with the bleeder, at this point it seems you only have the bleeder in the T stat housing, if thats even there, gonna have to question it with the way half your other stuff seemed to be missing, without that bleeder you cant get all of the air out of the system and you probably have air pockets.

 

so where do i get that?

i just used rubber heater hose. it has the bleeder on the stat housing.

if someone has a pic that would be cool, that helps me alot.

this is why i tried to pay someone on this, i literally dont know what i am doing.

 

You can see it here on the left by the alt fan.

 

so from there how does it get to the heater core?

is that a wrecking yard item?
