To find out if your 1971 Buick Riviera with a 455ci engine has a 5-blade or 7-blade fan, I recommend the following:
* Check your owner's manual: This should have details about your specific car's specifications.
* Look at the fan: If you can access the radiator and fan, you can physically count the blades.
* Consult a Buick enthusiast forum or website: Many dedicated forums and websites exist for Buick models. There's a good chance someone has already discussed this topic, and you might find helpful information.
* Contact a Buick parts dealer: They often have access to detailed information about specific models and their components.
Remember, finding the exact fan blade configuration for your 1971 Buick Riviera will require research and possibly some hands-on investigation.
