I don't know about Good but I find a lot of info on Youtube vids. Either take your chances there or someone here might link one they can vouch for as a good DIY.

The only issue I see time and again is those that leave air in the system. Gilley has posted often about the tips to keep that from happening.. RE; Air bleeder outlet up by the cowl on passenger side (I think).

** Here tis .... Guessing a vid of a person doing the flush/bleed using this feature probably knows what they are doing.

I just watched a couple vids on YouTube that were kind of helpful.

Slowly piecing it all together.

My car overheated today and I also noticed that my heater is only blowing cool air. I thought I'd just try and figure this out myself lol.

You need to have the system vacumed by a professional. You hava a air bubble in your cooling system and the bubble can be hard to get out. You probably opened up the cooling system at one point in time and introduced air into the cooling system.

dd posted about the pain in the ass it was when he did his and getting air bubbles but his experience many not be representative of everyone's.

No reason not to try it out and see as DIY - saves some $$

Probably want the car level or slightly high on the front end just a tad. If you run into problems, you can always take it in for a profess flush at just about any shop.
If your water pump is working it's probably just air in the system.

I should add that my experieces don't often go real smooth and I'm usually temped to have the work done at a shop.
Spark plugs, wheel spacers, suspension stuff,,, all going the long dollar when I want it done.

On a warmer day here, I'd try the coolant thing myself just b/c you really can't hurt anything. It's either get the air or it didn't work... try again or take it in.

The main thing is to get the front of the car elevated and go through the bleed/purge/burp process of the cooling replacment procedures. I think everyone's experience will be diffrent on this subject because it varies on where the air buble is trapped.
These Infiniti's cooling system are very complicated and are very low compared to other vhicales, so air can get trapped and conventional cooling purge/burp methods as seen in youtube videos MAY not help. I think its worth a shot to try it yourself but honestly I would have the system air vacumed and be done with it.

One trick i discoverd with my" flushing the radiator system then it overheating experience" is to do the general purge/burp routine with front elevated. Use one of those no spill yellow funnel's. After thats finished drive the vhicale on the highway to really get the system flowing and allow the thermostat to completly open up (drive the car kinda hard) then top off the cooling system. You should always do this with heater on hot and max/high on high power.
If that doesnt work the air is deep inside the system, it needs to be vacumed out!

I found the easiest way in many cars that i've had this problem with is:
Remove the cap from the radiator (not the coolant reservoir) and fill from there while the car is running. When the radiator is full put the cap on and let the car run the coolant through the motor. Keep an eye on your overfill tank so it doesnt overflow.

Use the bleed valve in the back if its necessary.

I used to sell my cars when something needed to be fixed. It was consumerism at it's peak.
And it was expensive.

Now I can focus on working rather than worrying about what I'll do in retirement.

I pretty much did exactly this and also changed my thermostat. Everything seems okay. So far. Lol
