The fan clutch on my W114 started going bad again (I've replaced it before) and I decided I wasn't going to pay the $100 plus for a new one again. For less than the amount of the clutch I bought a 16 in. (2600 cfm) electric fan to replace the one in front of the radiator and hooked it up so it comes on as stock (210F degree switch) and also anytime the A/C compressor is on. I ditched the stock fan clutch and got a adjustable, thermostatically controlled 14 in. (2100 cfm) to replace it. I just finished it today and haven't driven it too much yet. I've tried it with and without the A/C (85 degrees here today) and it is running about 190F in stop and go driving. If you don't mind deviating from stock this may be the way to go.
