Did I burp the cooling system properly?

So, I've finally researched and figured out my occasional overheating while going uphill issue is likely related to air bubbles in the system, since it started happening after a radiator change awhile back ago.

However, I read some instructions and there seems to be all sorts of ways to do a burp...and I went with the 1st one I saw. Placed car on ramps, opened radiator cap, race engine and turn on heater. I did it for 10-15 minutes, but I didn't really see any air bubbles come up. The coolant just sort of flowed over the radiator a bit. I won't know if it helped until my next long-distance uphill run.

Is there a specific way to do it that works? Do I have to place the car on an incline again, if I need to do it again?

Sometimes it works on ramps alone, sometimes it works better on ramps on an inclined driveway...gotta get that good steep angle going on

?
How long ago? If you've been driving it a while, it should have purged any trapped air by now.

Hmmm, over a year ago...I've switched between 3 different radiator caps as well, non of them seemed to fix the issue.

You're supposed to race the engine? Jacking it up really high in the front should be good enough. I thought you're supposed to let it idle. I squeezed the hoses and shook the car by the fenders. Seemed to work. Good luck.

Air and the cap aren't your problem.

Have you tried replacing the thermostat with a new Nissan OEM part? I think a lot of members buy Nissan OEM parts from courtesynissan.com. If you are having engine cooling problems, that's a fairly easy cooling system component to rule out. IIRC - Nissan OEM thermostats "fail open" to keep the engine from overheating during failure. The "fail open" by default approach is the reason I only use Nissan OEM thermostats.
