Detroit Diesel 1990 12V71TAB

Jack
Been here, done this.
I'm on the road using my phone to check YF.
I use pretty blue silicone hose and correct clamps.
My DDC shop provided the all of the different size hoses and gaskets.
You will be draining your coolant to do many hoses.
When I get back to my desk in the morning, I'll post some pictures and my shops contact info.
You will need to provide the engine serial numbers.

Agreed. We labeled each and photograph catalogued. We removed each, made one trip, had all new cut to length, new t-bolt clamps, returned and reinstalled. We did the same with oil and gear hoses. Drained all fluids first...

Oh, I don't need the serials, this shop will ask when you call.
Try to talk to Steve. He looked all the sizes up in some old manuals and ordered in what he did not have.
Several days later I picked up a box full of shinny blue hoses and lots of gaskets.
On my 12V71TIs, this was over 10 years ago.
On my friends 12V71TAs maybe 5 years ago. This also included 8" exhaust hump hoses.
My 10+ year old hoses still look shinny and new.

You can order the correct constant tension, T-bolt or Aba hose clamps for silicone hose, on-line.
Better clamps are expensive, don't go cheap here.

Sorry, I could not find any good engine/hose pictures. I'll take some next engine room visit.

Also, No silicone hoses go on the low (pickup side) of the raw water pump. The suction will cave the hose in.
I used fiber glass tubing here with short union hoses.


Tell this shop I sent you.
