Hi everyone, I have a 2002 H1, since I had the hummer I have experienced a few problems:

1) The oil pressure guage always seems to be low, even when I am on full throttle, the guage is not even reaching half way, is this normal?

2) When I am on the highway going around 70mph, the oil temperature would rise to the red line, however once I slow to 60 mph, the temperature would lower back tot normal again.

I have checked the oil level, and its fine. So any input on the above issues? Thank you very much!

Hi, I believe when moving it should read at 40.

Probably the oil pressure sending unit.
