Some of the Lumina radiators have oil lines and transmission lines hooked to them if this is the case with your car then there maybe a crack in the plastic tank on the side of the radiator I would recommend checking that before replacing the head gasket much cheaper and a lot easier if you bring it to a shop it usually will run about $125 for a replacement tank parts and labor included; if you do it on your own it will probably cost about $50. If it has no oil lines connected to the radiator then it is most likely the head gasket, and well that's not gonna be fun.
I have a 1993 Chevy lumina van that has heat but doesn't have a fan how do I fix the fan?
The only way to fix that problem is to buy a new radiator. Your old one has cracked around the fitting.
If the windshield wipers are not working on a 1990 Chevy Lumina, the problem could be with the wiper motor, the wiper motor relay, or a fuse. The least expensive fix to this problem will be replacing the fuse if it is blown.
trying to fix simular problem
Take it to the garage.
Remove the radiator and take it to a radiator shop.
$150-200 u need upper and lower intake gaskets new o-rings for injectors radiator fluid and you should change the oil
replace spark plugs and wires
It depends on the exact problem. If it's that both brake lights in the back do not work and the middle one works, it could be your turn signal switch.
If your lucky, get one from junkyard or from a cheap parts car.
I have a 92 lumina euro that did that and it turned out to be my crank sensor. The problem could also be the Torque Converter Clutch, bad plugs and wires, distributer cab, low idle could cause this to.
Go to the parts store and ask for a new one.
