How to Remove a Radiator From an Alero

The radiator of the Oldsmobile Alero is located directly behind the front grill and can be removed in about 30 minutes. The plastic tanks that are used on the Alero can be susceptible to cracking in extreme weather conditions. Occasionally, the radiator of the Alero can get clogged up or become damaged to the point that it needs to be replaced. You can save time and money by removing the radiator yourself.

Unfasten the negative battery cable of the Oldsmobile Alero from the battery post with an open-end wrench. Take the radiator cap off the top of the radiator, which is just behind the Alero front grill.
