I have a 1988 oldsmoble cutless cirra wih same problem I have replaced the colant fan switch and the coolant fan relay but to no avail have not solved this problem however the fan on the back side of the radiator does come on when I turn the key off but the fan on the front side of the radiator never comes on any help yet??? You might need a diode wire. *You may have a blockage in the coolent system which can prevent the flow of the hot coolent to the radiator fan switch. Check the temprature of the upper and lower radiator hoses carefully by touch. If the one of the hoses is cool while the other is hot there may be a blockage.

How do you switch out a radiator on a '95 Hyundai Accent?
First remove both of the radiator's upper and lower hoses, then remove the two bolts that hold the brackets that hold the radiator in place. Unplug both fans electrical harnesses and the small hose that connects to the radiator overflow reservoir. Now you should be able to pull the entire radiator out of the car including both fans that are held to the radiator by four bolts each.
