I know this is an old thread but...

I've used vinegar to etch an aluminum boat for paint prep, im not so sure running through your cooling system is a great idea. I may be wrong, if you ask my wife I usually am.

Glad to see this thread still helping people out :) I came back to the forum for a brush up on some maintenance things like the rear diff and transfer case, I'll have to use this for a refresher course on the Coolant too. haha.

Great write-ups, I love all the pics.

I do have a comment though. The danger of flushing with water like this is that you can never drain all of the water out of your engine. You guys need to be careful, as you are adding premix (50/50) coolant to your system, and there is a bunch of flush water still in the block and heater core which will dilute the 50/50 mix, which is not acceptable! (In Canada that will evenutally cause a cracked block due to the really cold temps in winter)

To darylzero's point, if you think you should have been able to get another 2qt into the system, that probably means there is close to 2qt of your 'flush' water in the engine. In reality, it may be closer to 1qt, and the other qt is air bubbles. But do the math, if 1/7qts is straight water, that means overall your solution is no longer 50/50, it would be closer to 42/58. (3/6 (qts put in) = 50%, 1/7 water, = 3/7 50/50 premix, which is 42%)

I could be wrong here, but use a hydrometer to test the boiling and freezing point of the new coolant, and if it doesn't meet the spec, you will need to add some undiluted coolant to bring the solution to the proper ratio.

I was thinking the same thing. I was about to do my 2008 Rogue S that I just rescued. I ordered the Green concentrate as I'm good with saving a few bucks and using distilled water from the store. I bought 2 gallons of Vinegar and then started wondering if that is safe because I did not notice the service manual mentioning a chemical flush of any kind (I could have missed it.)

Rogue Noob, still love the write-up! It's nice to see a Rogue-specific one with photos. Thanks! :bigthumb:

Hi. FYI, I just called the Nissan dealership near me and they charge $95 but use the green coolant. I asked if I could get the blue instead and he said let the guy know when you bring it in. Also, they apparently also use a solution to clean it out during the flush and then another solution with the new coolant as a conditioner (and OEM coolant).

Looks like the blue costs almost double the green ... the guy on the phone seemed a little wishy washy on whether the blue would be OK as he first said well, some cars cannot handle the blue but then he came back and said the blue can go in the cars that were designed for green but not the other way around. I guess I'll talk to the guy actually doing it.

Just did mine today
Several drain and changes ( 5-6 ) and the last drain I actually took lots of time to find the ENGINE DRAIN PLUG and it took forever to open it ( because of its angle and engine was hot-ish )

Tnx for the pictures
It helped a lot especially for the engine drain plug

No need to use any engine drain plug at all to flush if you remix using concentrate instead of 50/50. I flush on the run and use vinegar or even pool (muriatic) acid as a cleaner and you use sense doing it. No distilled water used ever and zero problems.

The type of antifreeze matters not one whit as no car uses any new materials that were not used even back in the '60s.
