Allure hose upgrade

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.

If you are interested in knowing more about this type of hose, Google 'Flexfab.'

A couple of things...the coolant you lost..was it mostly from the hoses when you disconnected them or was it from when you removed them from their point of origin or where they connect? Also, I was looking at mine since we have the same year and model and I see one of the hoses connect way back inside the engine compartment. Was one of them difficult to get at, as it appears on mine? Thanks

Dave, lost very little coolant from the hoses. I lost most of it from the nipple at the side of the radiator due to a fumble on my part. I learned quickly to do my first connection at the recovery tank, measure and cut the hose, slip on the clamp and do a quick swap at the other end. I did have to cut the old hoses with a knife at the ends to get them to release.

The one hose you see most deep in the engine bay goes to the turbo assembly. I was able to reach it fine by standing on a folding step stool and leaning in.
