Thanks

The hose connecting to the AST right below the radiator cap? It's about 2" around, and about 13" in length on mine.

 

Uhm...that sounds like you're talking about the upper coolant hose. The one from the AST is smaller and hoses are measured in ID (inner diameter) as far as I know, 2" would be a too big for the AST.

 

I think the AST overflow hose is 1/8"-3/16" ID.

There is no hose to the AST that is "2 inches around"...

 

does anyone know forsure?

 

Why not just buy the OEM part (N3A1-15-380C)? Those hoses are usually $10-$15 bucks or so from Ray.

 

Got one here in my hand. it's 7mm id or just over 1/4 and about 34" long. $17.44 from Ray

 

2 inches in OD (outside diameter).....

but I didn't know you wanted it measured in ID.

 

Use The ******* Search Function!!!!

 

sorry that is the wrong hose. gadd has the right one though.

 

So those of you who moved your AST, where did you get your coolant hose from?
Because right now Im using emissions hose and I want to use coolant hose but can't find any vendors. (stock hose wont work for my location)

 

autozone ftw....

 

Oh dear
