Ford ranger guage question Sign In

Ford Ranger, 2.3L, 4cylinder, 190000+ miles, 1995, Standard With aircon. Now the question: The needle on the oil pressure gauge has always in my ford been right on dead center to the oil can icon. Recently I have noticed that whenever I put the aircon on the needle moves to the high side of the icon just enough to almost miss the icon. When aircon is off , it goes right back to dead center. Now, should I worry about this?

Does it do this at all engine speeds or just idle? They do bump the idle up a little automatically when AC is on to keep alternator supplying the extra voltage and AC compressor at higher RPM to work more efficiently. You also are using more electrical load at that time so make sure this isn't a voltage issue and that the connections for power and ground are shiny clean and tight both at battery and where they go to. All body grounds too.

Re: Ford ranger guage question Sign In

Much better for it to go higher than lower eh? Smile

Those are what I call fake oil pressure gauges. Another words they stay near the middle when there is oil pressure. When there is no oil pressure it goes low. Basically that type of gauge is like an oil pressure warning lamp. It's either near the middle or its not. You may see it move a little but that is because of charging system voltage changing when the engine speed changes.

Re: Ford ranger guage question Sign In

Are you saying gauge read higher oil pressure with A/C on? Hmmm. About all oil gauges will read higher when cold and should be in range when idling when fully warmed up but lower than just sitting there and raising RPMs a bit. If A/C raises RPMs the oil pressure would go up a tad. If this is new and really only happens with A/C then I'm confused as to why.

IDK - you may want to get a mechanical gauge reading right on engine to see the real story apart from vehicle's gauge,

We are all like a bunch of gators in a pit and someone throws in slab of meat. There is going to be some fighting over it.

Those Yankees think Gator is some Redneck's nickname.

Yankees come down here and go to one of the lake parks. While walking their dog near the shore, they are surprised when a gator jumps out and snatches up lil FiFi.

The Ranger oil pressure gauges in those years are not really gauges like a normal oil pressure gauge. The gauge on those is like an idiot light that either shows the needle in the middle or low. It will never go high or in between middle and L. It may venture away from the middle, but that is due to system voltage and not oil pressure. The gauge doesn't use a sender. It uses an oil pressure switch like an oil pressure warning light would. It's a gauge wanna be that doesn't tell you anything but yes there is oil pressure or no there isn't. If you ground the wire at the sender with the ignition on, the gauge will go to the middle.

Still waiting for you southern guys to go up to AK and realize why you need to carry a gun when you fish. Gator has nothing on an angry griz. I also laugh when you wear coats in the summer.

Re: Ford ranger guage question Sign In

I wonder what a 14 foot 1000 lbs gator and a 700 lbs North American brown bear fight would look like?

How long can the bear hold his breath?

He probably wouldn't have to hold his breath for very long as soon as the gator bites the lil bears tail off as he is running away...Sly

Re: Ford ranger guage question Sign In

The right bear if determined would make hamburger out of a Gator. Claws like a chainsaw. Would like to see a Gator climb a tree or tear up a deck to get to a bird feeder and have seen that.

Can't come up with a pic but airport on Kodiak,AK you are greeted by a huge taxidermied mad bear! Family has first home there and have seen it,

Re: Ford ranger guage question Sign In

I guess you have never seen a large gator grab onto a limb and go into a death roll. If he gets you into the water, it's all over.

Re: Ford ranger guage question Sign In

prodrigsr - sorry for regulars here going way off the original issues of the thread. Just select "stop watching" and sorry again but it's funny for us (all volunteers) and get off topics once in a while.

Gators vs Bears. Silly as the two don't really habituate in same environments. Polar bears are very capable of crazy cold water and will pound out a hole in ocean ice in AK waiting for prey as seen on nature shows.

I think Nick here and I am the two regulars from the north at the moment and most others from the south. Doubt there could be a stand of of the two creatures as a gator couldn't take the cold or a cold country bear take the heat. No fight as they'd both croak.

I doubt either creature has any formidable challenge in their respective environments being top of the food chain,

Tom
