Yes, the previous owner did install one but he could not get it to work right... My current fan and radiator keep the car right at 160F at all time, even in heavy traffic, even in the hot summer valley so cal weather (highs at around 100F or a hair more). I actually have the coolest running car of my cruising group .

Without fan, while driving the temp goes up to 190, the radiator will still not boil over. But without fan anf without air movement (stop and go only) I now know it will boil over.

Down the road I will replace the termostat or try to trouble shoot the one currently installed to see why it did not trigger the fan when supposed to.

But I have other things more important on my to-do list right now
