Hi all, I'm getting 5.1 KM/L - I think this is poor but not 100% sure though - would be nice to know what the best mileage one can get from this 2002 Envoy Vortec 4.2L I6 engine - and / or perhaps what ways one can improve the gas mileage (gas is getting way too expensive nowadays) Thanks

Update; I was able to vacuum and recharge the A/C system; * BTW - Let Vacuum pressure sit for 5 days straight and did not drop below -26 Psi. Here are the results - Ambient Temp = 71 F With Compressor Running; Low Pressure Reading = approx. 41 Psi Hi Pressure Reading = approx. 152 Psi...

Hi Getting ready to add refrigerant but just double checking for the correct amount - (Standard A/C= 1.8 and with Rear A/C = 3) There is a console between the drivers and passenger seat - (see pic) does this mean this envoy its equipped with Rear A/C system? Thanks

Wow that is very good news :2thumbsup: as I thought with such a drop I would perhaps be dealing with a big, big leak somewhere - ok will proceed to perform 100% vacuum and then fill it up - then lets see what happens - thank you for your help !

Hi Ok today I hooked up vacuum ; Vacuum pressure Low side = between -29 psi to -30psi (but closer to -30 psi) Vacuum pressure High side = needle bottom out After 45 min; Low side = - 28 psi High side = needle bottom out After 90 min; Low side = -27 High side = needle bottom out After 150...

Ok I was finally able to remove the MODE actuator ONLY by using the Cool Tool as well - Great Minds Think Alike ! :) (took a while to build but wouldn't work without it) Here it is in Action LIVE on how it works ! Watch It Here....

Its very hard to see but TJ you have a very good eye 👁️ in spotting that hair line crack as that is exactly the way it is .. After many - many hours of fighting - yelling and screaming with that crazy actuator - it finally came off like butter - upcoming will share how I was able to do it :)...

Thanks TJ - As per your suggestion I plan to do some vacuuming tomorrow - last time I mentioned the word "vacuuming" out loud the better half jumped up for joy :bonk: When you said; " Is 29 inches of vacuum enough to properly evacuate a system before recharging in preparation for putting the...

Alright after tearing the car apart I was able to get to both the DEFROST and MODE actuator - TJ they are the same model as what you have - after some testing the DEFROST actuator seems to be working ok - just in case someone is wondering the way my actuators work - when cam at the 11 o'clock...

Mooseman, thanks for your suggestions :) * when I bypassed the low pressure switch to make the compressor run (momentarily) it DIDN"T make any noise at all - I didn't even hear it start up - so that is good news :) * thanks for the cool video - have now ordered a leak detector - and its on its...

Thanks TJ for your input - alright, I will NOT run the compressor at this stage - Now comes the fun part - In this state; * how does one go about confirming that the compressor is actually working as it should ? * What is the best method now (step by step) to search in determining whether...

Alright here is update; Actuators = Started to replaced the actuators and just more than 3 hours into it found out that I didn't have the proper sockets - went to Lordco and they didn't have any in stock - still searching - yes no room to move - really really tight spot - not happy :( A/C...

Ok will do - planning to do the actuators this weekend (as long as there is no rain 💦☔ ) - will keep you posted on how many times I have yelled and screamed while doing this - 🤣 Thanks again for your help thus far !!

Mooseman - thank you for your detail response - :) there is one thing I'm beginning to understand is that YOU really really really know your stuff !! NICE :2thumbsup: Yes it looks like I have 2 separate issues and lucky me both at same time :( As per your suggestions this is what I have done...
