coolant flush tip

i came up with this trick yesterday while flushing the cooling system on my '83 VF750F....the front cylinder drain bolt is hard to reach to re-insert..so i got piece of 1/2" O.D. clear vinyl tubing, slipped it over the shaft of a large phillips head screwdriver, leaving about 1/2" of the hose past the tip and a piece of tape on the handle to stop it from spinning....the 10 mm head of the bolt fits snug inside the tube and lets you start threading the bolt...worked perfectly

 

Smart move to open those cylinder block drain bolts. Few take the extra time to do a thorough job.

 

did the distilled vinegar and distilled water flush too...works great
