Renault Laguna III - 2.0dCI Sport Tourer Owner's Review - TeeCee

The problem with the spring types is that it's abso-ruddy-lutely essential to get 'em sat back perfectly in the hose identations left when it was removed, with the hose also pushed onto the pipe by exactly the same amount as when it came off. This applies whether or not the clip is replaced and the alternative is a leak. This probably isn't something a garage should let the lad do without oversight, as experience and "feel" are everything here.
A jubilee will usually crush everything into place and form a decent seal regardless.
Best approach is to replace the hose and its clips. If it's off anyway, it's a bit daft not to take the opportunity to replace a perishable object of indeterminate age and critical function with a known good one.
