I need information/advise on the hose fitted to a Yanmar 4JH3 T(B)E between the intercooler and the turbo housing,
The hose is quite short, 120-140mm, bore ~20mm. It is a clear, not internally reinforced, with a mesh outer reinforcing/protective sleeve ? It has been in place for at least the last 12 yrs.
Is it possible that this hose is silicon, or could it be common clear plastic hose !!??
Pictures show the hose and the connection spigots.
Any suggestions, should I replace it with standard coolant hose ?
