(89 Cherokee Pioneer 4.0L) I was reading some other posts in this group about cooling fans (electric) and it got me to wondering. My fan works but some times I notice it doesn't work. for instance, If I am sitting at a drive up window or a long stop light etc... sometimes it over heats. that is, until I put the transmission in park, then the fan kicks on. I have been keeping a watch on it and sometimes it works normally and sometimes I have to put it in park, then it comes on normally after that.
this sounds bizarre to me. am I nuts? is this possible?
I have AC, it works fine then, I have a brand new radiator and fresh coolant.
