Lower Rad Hose

[Michael R.]

Check for assumptions and variables.

Correct carrier radiator? Correct mounting blocks for the radiator not modified?
Correct mounting angle on the rear sloping tabs and isolator blocks of the radiator frame?
Engine front mounting points under the water pump arms correct with both the metal bracket as well as the composite isolator at the proper height. That isolator often becomes compressed. Compare existing used ones with NOS or new supplied by MAC'S.

Michael: Are you saying you think it should be a straight line from the water pump to the carrier rad? FUC-3 shows a preformed hose, and I found a preformed hose on the original carrier engine/rad I have on one of the spare hulls.

Hi Rob,
I have no concern that you or anyone else would not consider the variables on a specific project they are actually working on. I know it is not a straight line. I cuss each time I have to remove and replace the lower hose when the engine is in the carrier. I have learned that longer than necessary is not good, and a little heat to make the hose more pliable helps. That angle off the bottom radiator outlet heading into a straight water pump inlet is enough to convince us all the offset hose could be just the ticket.

I was writing from the broader view that we need to exercise caution when looking at images only. The image may be limited to the specific area of the lower rad hose.

I have samples of NOS lower rad hose from the former Levys parts stock. They lack a part number inventory tag or other form of identification to show they came from "the system" within CF Supply Depots before being sold off to Levys. They do not have an offset.

My copy of FUC-03 is at work right now, but the drawing of the cooling system shows a formed hose if I recall correctly.

I could tell a few horror stories about parts and rebuilds we used to get from Levys, but I can tell similar stories for many of the contractors who supply rebuilds for the DND. Worse yet, can you imagine the quality controls involved with parts that corrections canada (Corcan) removes from worn out vehicles and go back into the supply system? I opened a crate yesterday that had one of the nicest condition and identity tags I have ever seen stating the component was serviceable. It obviously was not.

[Michael R.]

No question what was correct at the time the drawing was made before the "B" series C01UC 103402-B was supplied.

I'll check the overall length of the one on the desk. I am thinking it may be a touch short for this application. The NAPA listing says the hose is 147mm, which works out to 5.78 long. The carrier listing shows 8-1/2, meaning the preformed hose may be 2-3/4 short. I guess the true test will be when I go to install it on the carrier.

Can the length disparity be offset by the difference between long and short water pumps? (does the short hose work with the long pump?)
I have not checked.
