DIY Coolant Flush/Refill?
 

Hi guys, i'm just wondering if there is an article for coolant flush and refill especially made for 350z/g35. I've noticed there's quite a few Youtube videos demonstrating the procedures but I think it's safer to follow one made especially for our cars. If anyone knows any, please LMK! Thanks in advance



I've got 2 more question to ask for those that have done coolant flushing:

1) In that same DIY here, it says to "fill the coolant until the coolant reaches the neck of the radiator cap (the level should be right to where the overflow hose is)." My question is, if I wait until it reaches the neck, it'd be too late since I would already have extra coolant in my funnel. Am I misinterpreting what the DIY says?

2) What brand of antifreeze do you guys all recommend, or are they all the same in terms of quality? Should I buy 50/50 antifreeze or mix it with distilled water myself?

enjoy.......

i just did this and it's very easy to do, but a PITA to get the air out of the lines. I just ordered the Lisle 24610 Spill-Free Funnel for the next time I have to do it.

It will cut a lot of time from removing the air out of the system.

One question, why do I have to replace the drain plug? Can't I just dry the old one and re-use?

I think "replace" means "reinstall".

Thats what I used and it was very easy considering I had never done it before.

Reuse it...

SO on the coolant flush is it necessary to drain the block too?

According to this DIY, it is not required since draining the block will be more difficult to do.

Great find on the DIY. Subbed

That DIY just tell you how to replace your current coolant, I don't see anything in there about how to flush it with water.

Consider Evan Waterless Coolant. Has a much higher boiling point.
