BMW E36 3 Series Cooling System Flush DIY
Furthermore, most manufacturers are now offering long warranty intervals and some even cover all your maintenance costs, just so that they can sell a car. That means that you basically have to do nothing and know nothing about your car.
Older cars though, are a different story. The E36 3 Series for example, comes from the 90s and didn't benefit from lifetime warranty or anything like that. Owning such a car these days means you're really passionate about Bimmers and you like doing some work yourself.
One of the things usually people forget to do is flush the cooling system every 2 or 3 years. By doing so they risk causing permanent and consistent damage to their engines due to various reasons we're not into right now.
To help you do this all by yourself, we found a great DIY guide here that explains both why and how to do this easy operation on your almost classic E36 3er. Good Luck!
