I had been alerted about the potential for the rubber hoses going to the coolant recovery tank on my Allure developing leaks. If one of these blows while underway, the result is obvious.....loss of coolant and dead on road until fixed.
The four small hoses (3/8") are actually fuel hose. Mine were rock hard and, as I progressed thru the replacement, I did find evidence of pinholes and some leaking at three fittings; at the radiator, at the turbo and at the recovery tank.
As recommended, I used silicone heater hose. These silicone hoses are used in heavy industry including in air craft. I found it at a local Cardinal Rubber Supply for about $1.47 per foot. It is very supple and flexible. It is recommended that you use special 'lined' hose clamps with this type of hose as the regular stainless worm gear clamps will cut into the outer sheath. I found the clamps at my local NAPA store for $1.99 per.
It only took about one hour to replace all four of the hoses. If you are careful and pretty quick (obviously with a cool engine and radiator cap removed to release any pressure in the system), loss of coolant is minimal. I lost perhaps a pint.
If you are so inclined to do so, suggest you check those hoses if you have this particular set up. I am an advocate of preventative maintenance to avoid unwanted interruptions in my valuable vacation and travel time.
