Open the radiator cap WHEN THE ENGINE IS COLD and simply pour it in. I have had good luck with Barrs stop leak. If this doesn't stop it you will have to seek professional help. Good luck.

If you every desrire to use the heater again, you should refrain from the use of radiator sealents - this applies to all makes and models. They tend to plug the heater core just like they seal the hole you desire to seal.

Do not use sealant, pull the radiator and have it fixed.

Everyone I know has had to have the radiator repaired due to cracks in the tanks.

As does my 1996 Caddy Concours, this vehicle -=[REQUIRES]=- the use of radiator conditioner from GM, or Barr's Leak which is the same, even made by the OEM manufacturer of the tripple-marked-up dealer only item. Also note the requirement for non-corrosive coolant; straight bihydrogen monoxide (water) or the green stuff will cause you more problems than a shotgun blast to the front e


you can either pour it into the coolent tank or you can unplug the upper radiator hose from the engine and pour it directly into the hose i recommend pouring it directly into the hose

: The overflow cap (radiator cap) is on top of the tank that sits on top of the dr. side fender under the hood.some of the newer cars do not have a "radiator cap" it goes in to the overflow tank . i would not suggest using radiator stop leak because it can clog up the radiator and heater core on the car if you must use it only as a last resort.

Where do you put radiator sealant in a 1997 olds aurora?

Sealant is a very temporary fix that should only be used as a last resort. It may patch the leak but will also likely plug up the heater core and elements, making it impossible to use the heater or air conditioner. If you do decide to put sealant in, you can remove the hose leading into the radiator and pour it into that, or put it directly into the coolant reservoir tank. Not all cars have a traditional radiator cap that is easily accessible.
