Lets talk cooling fans for a bit here. On some of these 87-91 models, at least 1 or 2 cooling fans are found behind the radiator. I have been paying close attention to these fans because I had my rad changed yesterday. On my car in particular, I have the heavy duty system, which includes 2 fans. 2 fans are standard on SSE models and optional on LE and SE trim Bonnevilles.
Under what conditions would these fans come on? Is the primary fan on all the time? Does it come on when the engine reaches a certain temp? Does running a 180T-stat affect the running of these fans. I went for a little drive after coming home from the shop to get the rad and I noticed when I popped the hood at home (engine on) the fans were not running
Is this normal?
