Just wondering is it really mandatory to replace the engine coolant at 100k? I'm almost near 100k and have done every other maintenance according to the maintenance schedule + few things of my own.

Any other things I should consider at 100k? Did spark plugs, replaced the trans fluid, will do differential fluid. Thanks!

I plan to do all fluid changes at 60k interval. Fluid is cheap. I like to have a peace of mind.

It's easy to change out 1 gallon of coolant. Drain the radiator with petcock...no tools required. Don't even have to raise the car. Remove overflow tank and dump out coolant. Fill coolant in overflow tank until slightly over full mark. Fill engine with remainder of 1 gallon coolant container. You're done.

Do this again in 1000 miles and you've replaced I think half the coolant? Someone I'm sure will chime in with the percentage.

But this is the easiest way to change coolant. I just replace 1 gallon every 30k miles and call it good.
