      @TOY SOLDI3R If you're just gliding, just keeping a certain speed on a level road, you'll need less fuel at a lower rpm. That's the reason why we change gear. If you need to speed up, go up a hill, you need the right gear to work against this outside added resistance. If the chosen gear is too high, you work against the engine that can't bring the power to the wheels if the gearbox has other plans. In those cases, you're not saving fuel.

      The most fuel economic thing you can do if you need to drive is to drive far-sighted. The light is red anyway, that guy will make a turn, you know the traffic at that time of the day and take a different route...all that will safe fuel.

        I had a oil gunked starter when I was kid once. An old man stuck a 2X4 on it and whacked the board with a hammer. Problem solved, other than the oil leak. But it was a pinto after all.

            I think on those dual AC units it might be better to leave both sides wide open. then if they stick maybe they will just be stuck wide open.

                          How long can a contrast additive be seen if the coolant leaks out somewhere?

                          I've got a leak but it takes about 3 months until you notice that it's gone.

                          I'm thinking about buying my own goggles/UV-Light to find it, but first I need another refill + the predator piss.

                                    RAF old radio engineers’ secret was the Drop Test. Remove equipment, lower it sharply to ground. Replace in aircraft. Do similar with your computer. Vacuum and brush the innards. Pull out and replace cable connectors. Unclip the boards, pull out a little, push back and lock.

                                      Have a 12 yr old Honda CRV. A couple of years ago I had the transmission flushed as recommended by manufacturer. When that happened the AC quit working correctly. The fan would blow but it wouldn’t start cooling until I hit 40 mph. No one could figure it out. I ended up getting a new AC. Complete system. Still wouldn’t cool until I hit 40. It was that way all summer & beginning of next summer. Then all of a sudden it started working. Any idea what caused this?

                                        @mrnt1257 No. It's just happenchance. It just happened while it was in the shop and not somewhere else. Perhaps the shop yanked some wire out of the way with too much force and damaged it, but there's no way to prove it. I had two similar things happen to me. In one instance, i gave the car for a MOT with working air conditioning, and they gave it back with inoperative air conditioning. Turns out the clutch coil thermal fuse went out inside the shop. It also happened out of the blue about 7 years later on the road, so it's just a bad clutch coil design. Another saw a shop puncture my AC refrigerant pipe. This time, thankfully enough, i videoed the engine bay before giving the car to the shop, and showed the video (where you clearly see no oil leaks on the ac line) to the shop's director, threatening to sue the shop. Got it fixed for free.

                                        TeraVolt so the transmission flush caused an electrical problem that just corrected itself? Seems to me something got stuck & finally unstuck.

                                        TeraVolt what would cause it to not run? And then suddenly start?

                                                So instead of fixing it properly, we should just leak refrigerant into the atmosphere and top it off when it gets less convient for our selfish selves. Got it. I mean who really needs an ozone right? If you can't afford to fix your vehicle properly, question your life decisions.

I can get it to run most of the time, except when it's super hot out, my car has sat in direct sunlight and it's hot out, or my car has sat idle with the AC running a lot. Traffic, lots of stops and starts, stuff like that. It will run cold then suddenly go hot. Sometimes it will come back on, sometimes it stay hot for the rest of the travel. Sometimes it comes back on after a few miles of travel with no stops.
                                                                    I've been told:
                                                                    my AC is clogged, and it was blown out. No change.
                                                                    my relay is bad, it was replaced. No change.
                                                                    the door that allows the switch from cold to hot might be bad, it was checked and deemed to not need replacing.
                                                                    I've even been told there's nothing wrong with my AC. But I beg to differ when I'm sitting in traffic, in 100 degree weather, and the AC is blowing even hotter air.
                                                                    I paid for a diagnostic and they said "maybe" my condenser needs replacing, which costs $400 plus.
                                                                    I can't afford to pay $400 on a maybe. I took it somewhere else and they said I needed freon, which I didn't, then I had to get that corrected because they put it to where the hi was lo and the lo was hi. Problems are still happening, every day of this horrid summer.

                                                                      If it comes back on after a little while, it smells wet and is super cold.

New connector and it's perfect again. When AC starts acting up, park the car and look if the compressor clutch is spinning, if not then try giving a good yank to the AC clutch's wire and connector and see if the clutch suddenly resumes spinning. If yes it's the connector. If the compressor clutch always keeps spinning when AC is acting up, then you might have a faulty expansion valve or moisture inside the AC system and again this gives erratic cooling because the refrigerant isn't always flowing through

I've been an ac tech for almost 40 years and never once have I used an manifold set to to discover the unit was low on refrigerant. The manifold set will tell you if something is not right on the system but for checking refrigerant come on man. All that is needed is to check the refrigerant charge is knowledge and an accurate thermometer. A bare hand will tell more than a manifold set will tell about the charge. I would be interested in hearing how you can check the charge with a manifold set. A manifold set is used only to check pressure, system temperature and system operation. Although the manifold set is handy for charging the system it is not necessary unless the superheat charge method is being done of which would be a waste of time on a leak prone system of an automobile.

Had PEP BOYS TAKE A PEEK said the compressor was bad but the system has no leaks and is fully charged. System blows hot air. But I can hear the compressor clicking.

With the constant automatic ventilation that meant some hot air always. Since I didn't have a shop manual on the vehicle I told him to take it to the Chevrolet dealer who does all the service anyway. I told him to ask for the old part back. They said it was a $80.00 cable that broke. Would cost over $800.00. He freaked but with a pregnant wife and needing AC for her I told him I would pay $500.00 to help him out. The tech who fixed it scratched up and damaged the dash taking it apart. The dealer agreed to fix the scratched and damaged dash and provide a free rental while they had the vehicle.

                                                                                      He gave me the old cable which I threw inside the top of my Mac box. About a week later I picked up the cable and it wasn't broken like they said it was. To me it looked like it just slipped off the wheel. I played with it for about 8 minutes and had it working fine. Didn't really need the part. But you know how it is when you go to a dealer for service. I was going to take the part back and question them about it. But they probably would have said it could jump off the wheel again and stop working so they just replaced it. I'm fine with that but they should have at least discussed what they found first. Chevrolet service sucks. I have owned three Corvettes and was never happy with their service. I feel bad for anyone who buys a new C8 and expects top notch service for their new car. To the techs at the Chevrolet dealer it's just another car.
