what is the best and proper coolant type and brand to use in my truck?
coolant on 2006 Toyota Tacoma
Toyota factory coolant for your specific year and model of your Truck. Get it form the dealer, that is what I do. It makes a big difference long term, because the additives are perfect for your engine and the bearing in your water pump. Change it every 30k or sooner.
especially never use Dexcool,it will ruin your cooling system
