CAUTION: Cover up the drive belts and pulleys using a clean shop cloth before sanding or filing to prevent metal filings from falling onto them.If no pressure marks or traces of rubbing are found on the hose as described, check the gap at the closest point (A) between the cast boss of the oil filter housing and the upper coolant hose.There must be a gap (A) of at least 1/4 inch (7 mm) when 10wnrakrtool the engine coolant is cold.If gap (A) is 1/4 inch (7 mm) or greater, no further repairs are necessary.If gap (A) is less than 1/4 inch (7 mm), the upper coolant hose must be replaced with the new modified version.Parts InformationUpper Coolant Hose BMW Part Number 11 531 433 340We replaced the upper radiator hose with the new type, cleaned the engine 10wnrakrtool compartment, filled the cooling system and pressure tested it to make sure there were no other leaks. Luckily, the engine hadn''t overheated. Most of the steam was created from the coolant leaking on the exhaust manifold. The owner was fairly good-natured about his near catastrophe. Relieved, standing at the counter while paying his bill, he said lightheartedly, "You know, my pants and shirt were badly wrinkled when I left the house this morning. I think this was the strangest way I''ve ever had my clothes pressed." I had to agree. ills

* Using the face of a clamp-type collar as a bearing surface in a rotary application. The saw slot can quickly abrade the surface rotating against it.Doug/Zero-Max: Improper tightening of multiple screws can cause bushing slippage. Axial movement of the bushing on the shaft when tightening can cause some alignment loss. Some connections feature a single tightening screw flint can be torqued if necessary for proper clamping force.Best practicesWhat are considered "best practices" when designing with locking devices?Carl/Ringfeder: Aside from the obvious design parameters, engineers should ask the following questions:* What are the application requirements of the device?* Is the locking device only used to simplify installation or is adjustment, removal, or maintenance necessary?
