Hello,

Owner's manual for my 01 Civic Sedan states engine coolant should first be replaced at 120,000 miles or 120 months. I am not near there yet and one of my relative's who is a mechanic said I should not wait that long to have the coolant changed. I think he is right. Any thoughts on why the owner's manual states coolant need not be changed sooner? I do get the fluid levels checked regularly.

Thank you.

 

Many newer cars are designed to be able to run longer intervals on fluids. It doesn't mean you should wait that long. Some climates have to change the coolant twice a year anyway, to cover the extreme differences between summer and winter temps.

I wouldn't want any fluid in my car for that long. Acids and other contaminants build up. Many newer fluids are more resistant to this, but coolant is too cheap to NOT change it more frequently.

 

Thanks. I really don't think they should have printed that in the owner's manual.
