6 or 8 years back I was having some overheating issues, mostly after prolonged highway speeds or after exiting a highway. Temps would climb above the first bar of our dummy temp gauges towards the second bar. I ended up pulling the fan clutch and separating the halves and the silicon had turned into a dark brown sticky syrup. I cleaned it out best I could and refilled with half 3,000 CST and half 6,000 CST silicon, slapped her back together and the problem was solved.
Late last summer i started to see signs that my temps were rising again, but were not as concerning. I did a full flush and fill with new coolant in the fall and just bought a new Aisin fan clutch. I think my old rehabbed one could be the original and could be on its way out. Before I install it I’m curious to hear if anyone has modified their fan clutch like you see in the 80’s forum ( lowered opening temps and thicker silicon)? I’ve got some tubes of 8K, 10K and 15K CST on the shelf. Gets hot here in Texas so I’m thinking about cracking open the new one and beefing up the silicon before installing, any thoughts or experience? ‘77 original 2F here.
