Hi guys. As the title suggests, my 3 week old coolant looks pretty disgusting and i can't tell if its oil or gunk that i didn't flush out during the recent radiator drain.
Coolant is 3 weeks old where i replaced a faulty radiator temp switch. The mini doesn't overheat even in heavy traffic now (it used to because the aux fan wasn't coming on ... but it went into the red probably 3 times total). Looked into the rocker cover and it seems fine.
Here're some photos of the radiator, looking into the rocker and soaking up the gunk with a paper towel. What do you guys think?
