Question about 1993 Chevrolet Lumina
Posted by Anonymous on
If the radiator cap is not allowing the radiator to maintain proper pressure, the coolant will boil and overflow the bottle reservoir.
Check radiator pressure and replace the cap if the pressure drops.
Hope this helps.

I found this forum site and from what I can discern, both fans should be running once engine temperature sensor turns them on. Can you switch wiring from 1 fan to the other? This would let you know whether you have a faulty motor or relay. Maybe you can pick up some tips too.

no fan comes on when engine cold start up .but it will come on when you turn on air conditioning or defrost on .if engine idling a while when temp get 190 degree the fan will kick on.if over heating you got air in system .wait until cools check coolant add more .crank engine let it idle few. minutes when start warming up turn off engine wait a while before removing radiator cap so you wont get scald.add more coolant .crank it again starting warming up turn off engine wait a while .add coolant .keep doing this procedure until your coolant stop dropping off .if you do this more than 6 times you got a leak some where.check crank level for signs.if oil level higher than normal.if everything looking good.when engine cool make sure add coolant to over flow jug cold level mark.

If your car is equipped with a 3.1 or a 3.4 litre V6 and you have preformed all of the above listed work then I would have to say its the intake manifold gaskets. They commonly blow on these motors. Just a design flaw, nothing but replacing them when they leak can fix this. Also run a coolant pressure test on the system to check for minor things like a leak that you cant see from visual inspection. Hope this helps.
