Quick tip re leaking SLS hose.

Post by KimB » Sun 10 Jun, 2018 2:28 pm

I was losing fluid from the self leveling suspension reservoir container located in the engine compartment of the 380SEC.

Thinking it was the braided hose that ran from the bottom of the container to the SLS pump, I assumed the hose had started to rot out from the inside due to age.

I took it to my local indy, Roland Grellinger, for him to have a look. After removing the container, he found that the hose retaining clamp at the bottom had worked loose.

So he tightened the clamp up and all is good! Roland said it is a common problem and most people think the hose itself is the culprit.

I had same problem though when I tried to tighten the clamp it was already as tight as it could be. I removed the clamp and cut about 1/2 inch (12mm) of the end and replaced it, clamped it and now all good. Might help next time if clamp tightening fails.
