How-To Fix Coolant Gurgling and No Heat On a Nissan Frontier and Xterra

I discuss how to check the level of your coolant on your Nissan Frontier and Xterra. This can apply to other vehicles as well but there I provide some specific details gear toward the Nissan. If you are having gurgling sounds under the riders dash or experiencing no heat at a stop or start then your coolant level is too low. Filling up your coolant to the proper level is easy. I recommend using the manufactures recommendation of coolant when refilling. This fix applies to the 4.0 L and the 3.8 L Nissan engines. On most new model vehicles the manufacture will use 100k mile coolant so that is why I recommend sticking with OEM. This fix will take you all of 5 minutes but you will want to make sure you keeping checking the level of the coolant and filling it up to the max line or no more than 1in above (this recommendation is only for the Nissan Frontier/Xterra but all other information can apply to other makes and models).
