ok guys i need some help i just picked up this 01 blazer and im wondering if this tube has to be connected to anything... or is it just a vent tube


idk what this is either but, this is what its connected to on the bottom of the radiator

 

That is the AIR (air injection reaction) pump intake tube. It should be zip tied to the radiator shroud on the passenger side of the radiator. It should not be back where it can get caught in the fan.

 

i know that is it supposed to be connected somewhere to the motor or just left open like that (i just bent it that way to get a better picture)

 

As stated, it is the intake tube... It doesn't need to connect to anything but the AIR pump under the radiator. The other end is open to let air into the pump.

 

ok thanks wasnt sure if it needed to be connected to anything important

 

Like said, just make sure its ziptied to something to keep it out of the fan.
