I have been reading the posts on this, and still have a question: My fan clutch on my 67 327/300hp car is the Eaton replacement style unit with the coil spring. The clutch was purchased in the mid 80's but has probably only seen 1000 miles since then. From what I understand, my unit is probably designed to engage at too hot a temp for my car (like maybe 210 deg. F). The clutch doesn't appear to be engaging by using the spin count techniques mentioned in earlier posts. It doesn't appear to be acting any different now than when it was new, just probably the wrong engagement temp? Does this sound right?
Next question is this: Should I try the simple adjustment as mentioned in various articles? They describe moving the tang around to the opposite side, but that obviously completely overrides the thermostat funcion. I suspect the tang only needs to be moved a few degrees. I tried heating the spring up with a blow dryer and it only moves maybe 20 degs no matter how hot I try to get it. Clearly 180 degrees is overkill.
Any advice?
