Engine Coolant for Nissan Versa

The lady at the Autoparts place was saying “Dex-Cool”. I was like “Dex-Cool?” I thought Dex-cool was for GM vehicles. Also the mechanic said his shop is particular about what they use fluid wise when it comes to vehicles. They will only add what manufacturers recomend for the vehicles. It makes sense, especially if the vehicles are still under warranty. He says its not critcally low, he just wanted to bring it to my attention. I’m glad he did. Also they said a flush was unnecessary. I’ll have to look in the manual and see when they recomend that service to be done.
