Welcome to Just Commodores, a site specifically designed for all people who share the same passion as yourself.
When l did mine (6l50), the difference was 6 degrees. I wasn't putting in enough with the if temp gun.Use an infra red temperature gun to check the fluid temp at the pan. I’ve never seen more than a couple of degrees difference to what the scan tool displays.
Don't overthink it. If the program with the Elm 327 works just use that. 35 degrees is fine.As you all know I love testing things so what I will do as long as I dont forget is I will use via the OBD2 327 Cable Street Program (always forget the name of it) thanks for Tazzie, Argggggh by the way I contacted Tazzie about this is his program will work on a WN series cars but the the same time the same day the Forum had a upgrade so maybe the PM went missing. Anyhow I wil use his program to tell me say 35 deg C then remove the already loosen plug to see what happens but if nothing come out I have add more or start the process again but at the same time I will check the IR Gun itself for accuracy itself. or Nominate 30 deg C only.
What do you recon guys is 35 deg ok to check as if a lot come out then it goes to a trickle I it will put the plug in and I say IT OK!!
Yes I will write downs a list so I dont forget anything "eg" go through all the gears for at least 10 seconds and other.
Yes, Yes because this is one of my Failure after my Strokes "eg" forgetting stepsDon't overthink it. If the program with the Elm 327 works just use that. 35 degrees is fine.
Good idea to write a checklist and mark it off.
