Nissan Frontier *FIX* Water Noise Behind Dash/Poor Heat Output

In this video I show you how I topped off coolant that was filled low from the factory which ultimately solved the issue of a water sloshing sound from behind my dash and improved heat output on my 2023 Nissan Frontier Sv. This process is the same for 2022+ Nissan Frontiers for all trim levels. 2022 2023 2024 2025 s sv pro4x prox Coolant used in video: Pentofrost A3 Something that I should have mentioned in the video but forgot to address, if you are low on coolant there is also a good chance that you may have a leak somewhere. It’s a good idea to also check for leaks after you top off coolant. In my case the truck was new and coolant was improperly filled, which resulted in the issues I was having. #nissan #frontier #coolant #water #noise #sv #pro4x #problem #nismo #4x4 #heat #truck #trucks #broken #2020 #2021 #2022 #2023 #2024 #2025 #fix #replace #replacement #stutter #mpg #mileage #fuels #bad #tacoma #taco #tacomas #truck #diy #howto #maintenance #service #2ndgen #2ndgeneration #toyota #toyotatrucks #toyotacars #v6 #vsix #clean #cleaning #gasoline #gasoline #exhaust #maf #fuelefficiency #fuel #fuelefficienttruck #better #fuelefficiency #rough #start #startup #startups #engine #running #run #idle #idling #problemsolving #problem #wontrun #coolantleak #coolant #factory #noises #water #sound
