I see various threads about what will fit. has anyone summarized this? What are my choices? I currently have (I think) A stock radiatior for a DX EG hatch. The inlets are of a smaller diameter than the hoses coming off the B18 Block. The solution currently is a smaller diameter hose inside the oversized hose with a clamp cinching around both. I have a leak, (small) havent yet decided if it is the hose junction or the radiator itself. If it is hoses is there a better stockor aftermarket hose that fits? If it is the radiator, what are my choice for replacement, and what if any modifications do I have to make to change to something more optimal?
