Upper Radiator Hose - do I have the correct part?
Hi all,
I'm in the middle of replacing the cooling system hoses on the gold '86.5 and ran into a snag with the upper radiator hose where it connects to the water manifold. The new hose will not go on due to a difference in the diameters of the hose and water manifold nipple.
The inner diameter of the new hose (928.106.238.08 by CRP Industries) is 1 3/4" at the water manifold end whereas the corresponding nipple on the water manifold housing is 2" in diameter (2 1/8" if you factor in the metal ring).
The old hose (#928.106.238.04 - original 20+ year old part) inner diameter at the water manifold end is 2". When I replaced the hoses on the green '86.5 last year, I didn't have this issue. I found the old hose from that car and it too was 2" in diameter on the water manifold end.
According to the PET, 928.106.238.08 is the correct part# for my model year.
Has anyone encountered this problem before?
If so, what was the resolution?
Thanks,
Adam

Hi Adam,
The hose needs to be a tight fit. If you use some dishwasher liquid it slides on there very easily and is a perfect fit. I cannot compare it to a Porsche hose as I do not have one. I suspect that the diameters would be the same or similar. We need to compare new for new as an old hose will have taken a set of the diameter it slides over.
CRP & Elaplast are the 2 OE's I am aware of.

Hi Adam,
Glad that worked, however I will order a Porsche hose to double check that the OEM hoses are the same.
Thanks for the heads up.

I have found that different distributors sell different hoses and also different thickness hoses .
I got 2 sets at the shop one from the dealer and one from one of the suppliers I went with the dealer hoses since they looked like original hoses and the original thickness .
The supplier parts were thinner walled and also bent slightly differently
