I am going to flush out the DEX tonight and put green stuff in.

Does anyone know the size of the inlet hose to the heater core?

Assuming the top hose is the inlet right?

The reason I ask is because I am putting a T in the top inlet hose, and I want to make sure I have the right size T, before I slice it open.

Thanks

I don't know the size off hand, but the top one is the inlet. If you buy the Prestone flush kit, it comes with various sized Ts, and one of them will fit.

I have two remaning of 3 sizes, I used one in my '95 lumina with the 3.1L that stayed with the car

The largest one looks like it may fit... i think it'* 3/8ths?

Well Atleast I got my 180 T-stat in.

I am much more relaxed now...knowing that the big time heat is gone.
