I installed my DeWitts E97EL radiator a couple of weeks ago and now they just called and said the GM hose assembly for the EOC is off backorder. How hard is this install? I don't have a lift but it's a tad cramped with the car on my ramps.

Should I opt for a shop with a lift?

TIA,

John

Not sure exactly what you are asking, but it's hardly necessary to put your car on a lift to install a couple of EOC hoses. The hardest part of that job is finding somewhere to route the hoses and keeping them off the headers and moving parts of the serpentine belt.

I was asking about the end that attaches to the motor. The ends that attaches to the radiator won't be an issue.

Oh, I used something a little bigger, and was told it was necessary to be bigger. I think these are #10 lines (5/8th inch).



Although I'm not certain that bigger lines necessarily mean more flow, because that is dependent on the type of pump being used.

John, with that setup I had to unbolt the motor mount and jack up the engine a bit to get the lines in not to bad really and I did it on jack stands in the front only. then used a block of wood and my floor jack to lift the engine a bit. It didn't take too long after iquit wrestling it and jacked up the engine to get it in and hooked up. as for the sizes of the hose vs the hard lines Dewitts test showed more flow capacity with the hard lines. which is the OEM choice also

I'd like to see a link to that 'test' if you have it. I can believe that the flow is equal, if the oil pump is a positive displacement pump (which it may be, I'm not sure) but I absolutely don't believe smaller lines with lots of bends in them flow better than smooth hose with bigger lines.

Thanks Ernie, that's what I was needing.

It might be on Dewitts site although it was a phone conversation with Tom Dewitt he makes both types so has nothing to gain by pushing one over the other
