I just found the service manual online. It's showing to change the coolant every 36000 miles. Did they use the 100000 mile coolant in 2012?The process itself is pretty easy from what I've read in the service manual. If you bought your car new, the Blue Honda coolant is actually long life and rated for 100k mile so long as any mom and pop shop didn't top it off with some other stuff...
My local dealership charges $150 for a coolant flush, when it would take probably twenty minutes or so do to yourself plus about $30 bucks for the coolant from Honda.
My Accord is at 63K now and at 20% on the MM - as soon as it goes to 15% and tells me what I need to do, it's getting drained and filled again.
Measure the coolant with a voltmeter with the negative lead of the voltmeter on the battery (-) terminal and the positive lead of the voltmeter in the coolant while the coolant is at operating temperature.I have 2012 LX-P 4 cylinder with 34000 miles. What is the recommended change interval for the coolant. Do you just drain the radiator or have it flushed at the dealer? Thanks for the input.
Miker - awesome information here. I had no idea this was a way to test it. Thank you for this, for sure!
You are welcome.As always, Miker has excellent info and a nice writing style.
I wanted to add that the 7th Gen manual backs up his point. 1st coolant change is at 7 years or 105,000 miles, then 3 years or 36,000 miles thereafter, even though you are still using the Honda "blue" long life coolant.
A radiator drain and fill is all that is required, though some back flush the engine block (I do not). The "old" stuff is not poison, it is just fluid that needs refreshing. After all, you don't drop your oil pan and clean it with every oil change, do you?
