Hi, I need to replace my original heater hoses. There is one that comes from the pump and goes to the heater core and there is a smaller hose that tees off and goes the intake manifold. I cannot find the reason for the smaller hose. Do you think I can eliminate it? See photo.

You can buuut it does kind of help reduce air pockets and cyl head hot spots

 

Thanks, I did not know, it makes sense.

I will keep it, I have been looking for an original but no luck.

when you replace hose see if the intake fitting can be removed its pot metal and will probably crumble! so be warned - my 87 ended up towed to dealer for warranty intake replacement Later I replaced with brass fitting, if you dont it could leave you high and dry at worst possible moment my .02c

 

I was looking at the manifold today, Its not going to come off. I am installing a new manifold, and will do brass.
Thanks for your input,

Louis
