Re: Radiator fans will not run unless AC is on

You need the 50/50 mix, 225 is the turn on point in most modern vehicles. The 2 fans may run at a slower speed with ac as opposed to the high temp turn on, the programming for that can vary. Make sure the system is bled, info on how to is on youtube. The cap could be bad, not holding pressure, cheap enough, replace it.
