Why You Shouldn't Ignore Your Toyota Tacoma's 100,000 Mile Coolant Service

At 100,000 miles, my 2018 Toyota Tacoma TRD Sport was due for cooling-system maintenance, so in this video I walk through a radiator coolant drain and fill using Toyota Super Long Life Coolant.

This is a DIY coolant change for the 2016–2023 3rd Gen Toyota Tacoma. I show where to drain the radiator, how I refill the system, how I work air out of the cooling system, and the checks I make afterward.

This is a drain and fill, not a chemical or machine-powered coolant flush. If you’re searching for Toyota Tacoma coolant replacement, radiator drain and fill, 100K-mile maintenance, or 3rd Gen Tacoma cooling-system service, this is the process I used on my truck.
