So.....it IS both a temperature sensor and an oil level sensor after all! Does anyone know what kind of warning I would get or if it would drop into "Limp' mode when oil temps are outside parameters?

Somewhere I saw it was both an oil level and temperature sensor but it looks like it's only an oil level sensor. I couldn't find anything mentioned in my owners manual either.

Thank you for the feedback and the links all. I have the adapter in the front in place and temporarily plugged until I decide on a gauge and mount. I have been looking for a blue tooth type of sensor that can cast to an app on my phone but they are prohibitively expensive. Has anyone seen...

Where will I get a notice and what kind of notice will it be for temperature?

Finally adding a true oil pressure gauge. I don't want to run an oil line into the Envoy so am going with a wired one. Would you go with a digital or analog style? What P.S.I. range? 2002 4.2

Hi Mooseman, I did put an oil pressure gauge on it a few years ago when I first had the problem. It was a temporary hand held type that I ran the hose up to the windshield and could watch while driving. I think I posted the results on here somewhere. The numbers were good. I put an AC Delco...

I thought I had the problem solved. Berrymans crankcase soak, new pressure switch, Valvoline R&P. Etc.....I hadn't towed my 2000 lb trailer in two years. With all of my driving to the desert, four wheeling, driving around town, pulling long grades I haven't had the low oil pressure warning...

207k miles on what I believe is the original fuel pump. Envoy still running perfectly. No abnormal noise from the pump. Installed a new filter last year and everything looks good. How long do these pumps go? Should I replace it if it's still working just fine? I'm planning a 2-3000 mile...

Thanks for the replies all. Sorry Mooseman for the double post. I couldn't find the previous post this morning. I thought maybe it got lost. I didn't look in the technical section. 😃

Is there a filter screen under the oil pressure switch? 2002 Envoy 4.2

I've been hearing about a fine screen that is under the oil pressure switch. While my Envoy is doing good after my new pressure switch, a Berryman's Crankcase soak, and running Valvoline Restore and Protect. I'm wondering if there really is a screen under the pressure switch, if it would be...

Old battery 5 years old finally gave up the ghost. What should have been a ln easy swap turned into a 3-4 hour ordeal. The positive battery cable was replaced around 2.5 years ago. Brand new O.E.M. AC Delco. The negative cable was just cleaned In that short time the positive cable looked...

I am going to install the Firestone air bags inside my stock coil springs. 2002 GMC Envoy, 4x4. The instructions show the air lines going out of the bottom. I see that as a potential problem with ground clearance. I do some offloading and picture the lines being damaged. Does anyone use...

I'm seeing these supplemental oil feed line kits for my 4.2 Atlas. They take oil from accessory port in front by the oil filter and run it to the back of the block to add additional oil supply to the rear main bearings. My Envoy has 205k miles but is in excellent condition. Meticulously...

I do have the GU6/3.42 ratio diffs.
