Pulled the old fluid out yesterday... Red still, but fairly dirty. No signs of water either. Am going to check on the cooler today. Ron noted it's a good idea to have a water strainer inline. Mine did not have one. Guess it's too old! FYI - did some research on the dipstick assembly. Seems like they can be found for the velvet drives by Borg Warner, but they go for about $60. My rubber is pretty wrecked, but it still seals, so the nice new shiny handle/ dipstick is gonna have to wait!
