Do the F53 gauges actually work?

On my Itasca Suncruiser the temp, oil, amp gauges always read right in the middle. Are they actually reading anything or are they just indicators that something is working? I think I read somewhere on another forum a long time ago that they really don't show much. Thanks

Many members here post.. they all have their doubts that factory dash gauges do anything until too late.. many recommend SCAN GAUGE .. I use added gauge that are dedicated.. and know to be reputable.. I also have and use obd2 scanner in live data capture mode.. yes.. it's a bear to run 6 gauges independently.. and time consuming.. scan gauge just plugs in.. my dash does look like cockpit.. but old school.. I find scan gauge hard to read.. but most say it's the way to go..
Good luck and let us know what you did and maybe better members then me will help you

The F53 gauges are just indicators of that something is working. The temperature gauges will not move off dead center until there is an overheat conndition (too late). I use ScanGauge II which provides digital readings of actual temps. Now I see the temps rise when going up mountains and see them go down when coasting downhill, etc. Of course the ScanGauge monitors a lot of data points besides just temps.

They are just like idiot lights. On/off. By the time they show a problem it is too late as stated above.

The gauges are electronic and controlled by the ECU rather than the older analog type that were directly connected to the source sensor. Considering this I suspect they are more of a range indicator and will move in steps rather than something more analog like a fuel level gauge.

Checked my Temp gauge with my OBD reader just to see what the real temp was - right on with the thermostat.
My volt meter is right on.
No info on the oil pressure. It registers when the engine is running, but not sure of anything else.

My 1993 has a "real" oil pressure gauge. Evidenced by the type of sending unit at the engine, which larger than the "idiot light" style. My 1995 F150 has the idiot gauge. So right in between there was where Ford decided the public didn't need actual oil pressure readings. Rumor has it that is was a warranty thing and dealerships were fed up with customers coming in and fretting over lower oil pressures at hot idle. IE, they had no clue how a gauge is supposed to work nor engine oil pressure. Have been on that side of automotive service, I can actually believe that.
I think I saw somewhere where temp gauges were being altered to show cold, normal, and hot. Basically. For the same reasons. Sad and I expect true.

On my old truck I can alter the gauge wiring, swap senders, and have an oil pressure gauge that actually works though I can't seem to get around to doing so. Unfortunately on the later models all that runs through the computer and you can't pull that off.

I have a ScanGuage and ODBII reader and the dash guages all match pretty closely the readouts from those two digital devices. With the $20 BlueTooth ODBII reader and the Free TorqueLite application on your android tablet or phone you can display just about any digital or analog gauge imaginable however the dash is pretty accurate once you understand what the ranges they display are.

That the V10 in the F53 is usually so stable under normal/moderate driving conditions probably creates some confusion however when you beat that horse and try to drive up mountains fully loaded at 75 MPH instead of slowing down to a more reasonable speed you can see the engine power load go completely up to 100% and especially when Effective or Real Feel outside temperatures are at 100 degrees plus you will see a rapid increase in engine temperature indicated on both the OBDII readout and the dash gauges and rightly so since motor homes and their tires are not designed to maintain speeds over 65 MPH for long periods and especially not when pulling a grade in hot weather. You have to be mindful that a V10 engine when running at 100% output can be burning as much as 1 gallon of fuel per mile which simplistically stated equates to over 120,000 BTU or around 131,760,000 joules which is a lot of heat for your cooling system to deal with every minute your running at that power level.

When I drained and filled my coolant system, I started up the beast and watched hoe the engine coolant and transmission temperatures slowly rose and creeped past “normal” toward “hot”. I turned off the engine and let everything cool down. Next morning the coolant reservoir level dropped was down from the full max level to about 1/3 full. Started the beast again and temps only rose to normal. The indicators definitely changed in a step pattern likely created by a computer chip, unlike the old analog gauges of yore.
