[C320-list] Coolant leak

[Robert E. Sloat]

Bob-I have a 2002 C320 and a very slight leak developed a few years ago at 
the same fitting.  I just removed the fitting and wrapped the threads with 
teflon tape and put it back on and the leak stopped.  Do this when the 
engine is cold, remove the radiator cap to eliminate any pressure in the 
system, have someone put their finger over the hole on the engine block and 
raise the hose to the hot water heater after you remove the fitting.  This 
will almost eliminate any coolant leakage during the repair.  I did this and 
it was a 5 minute job with about a tablespoon of coolant deposited on the 
paper towels place below the fitting.
