there is a greyish tan thing that is no longer attached to any thing what was it for?

 

maybe part of air management system? I will look under my hood tonight

 

Where does the other end of that hose go? Looks kind of like someone did a quickie block off for the heater hose connection coming off the radiator.

 

sorry, forgot to get back to you. bet that is part of the air management system, check out these photos

 

Here I took your pic and outlined some things in paint

 

the first shenannaguns is some original insulation on a cooling line

the second thing on the radiator itself looks big in the picture but it really just a sensor that is not used (the radiator was replaced by the previous owner). there's no way that the hose on my car or yours from the air management system could plub there because the hose is too big for that connection & theres a prong for a sensor wire that the picture doesn't show too.

My guess is you air management system wasn't kept when the nice upgrade to a 355 was done. do you have headers?

Think he's probably right. See if the other end of the hose goes to a steel tube that runs along the frame towards the fire wall.

 

Based on the notes you made on that photo — yep, someone did a quick way to block off the heater hose port on your radiator.

The Low Coolant Sensor on the radiator is lower down on the tank. What he circled on your photo is the heater hose connection that's just below the fill neck. Looks like you've got a piece of a rag or something stuffed in there.

 

I have heater hoses off intake. no rag, looks like could be hard gasket like material. no leaks so good to go

 

thanks guys


no to the headers

 

It looks like someone plugged the hose with an old distributor rotor from a small cap hei. Mike

 

Hey 83z28, you've got a darn good eye!! I think you're right!!

 

And in scooter 500's pics, that nonsense is the pre 87 AC crap. I ripped all of it out. So much more room. Soon with the LS1 fans. And the serpentine setup.
