Question about 1991 Oldsmobile Cutlass Ciera
If you put coolant(antifreeze) in the coolant resivoir and radiator and it,s been leaking for 3 weeks be careful. The engine should be low on coolant and it can run hot into the red zone and be destroyed and maybe cause a fire.Look under the hood in front of the firewall,by the rear of the engine . You should see one heater hose that enters the fire wall and another that exits the fire wall. Autozone,etc. will sell you a couple of hose clamps and a little piece of plastic pipe that ypou can use to by-pass the heater. Be aware that you ain,t gonna be able to defrost the windshield,etc. after you by pass the heater. BTW - that 4 cylinder engine is plagued with overheat problems. it,s a factory made disaster.

First you`ll have no heat if you do this,but you already know this. Depending on whether you have a 4or6 cylinder really shouldn`t matter, with a 4 you should be able to see the down below the exhaust on the drivers side under the steering arm on the firewall two black hoses these are what you need to block. Now for the the actual work,raise the the car,drain the fluid. Back by the firewall from underneath you should be able to see the hoses,depending on wether you have the original or the normal screw type clamps they will have to be removed,the screw type are a little easier to take off. If you still have the original clamps auto stores usually have a special locking pliers type tool for making the job a little easier cause these clamps have to be kept open to slide them back on the hose. Once the clamps are out of the way you`ll have to gently pry the hoses off the heater core.Wear protective eyeware as the core will still have fluid in it. Now if you can get or bend a piece of 1/2 inch aluminum tubing to put in the open ends of the hose from the top pull the ends of the tubes up where you can get to them fit in the tube and put on the clamps. It is best to use the screw type clamps because these will have to be tight and unfortunately only one off the tubes are 1/2 inch the other is probably 5/8 inch make shure that once you have connected the piece off tubing to the hoses you position it away from the exhaust pipes and secure it. Also you`ll notice a black pastic box looking thing somewhere along the heater hoses DO NOT MESS WITH IT or you`ll be buying a new heater hose.Good luck Ken firstname.lastname@example.org
