How long for radiator fans to come on? - Honda Prelude Forum

My coolant level was a bit low in the radiator so I went to add coolant and bleed the system as per the Honda/Helms manual and the engine temp came up about normal speed but the fans didn't come on.
Of course I started this just before dark so I only gave it around 15 minutes but shouldn't it have gotten hot enough to run the fans in that time?

Same here, ive never seen them on unless my csr is actually over heating.

My fans turned on a little bit after taking an hour + drive.. They dont often come on while the car is not in motion i dont think.. or otherwise overheating. *shrug*

Well I guess thats good to know.

But how would you go about checking the fans to make sure that they actually work?
