This concerns the MY16 V6S. The temperature gauge is the left right of a circle. At the bottom there is a very small blue zone and at the top, a very small red zone. At the exact middle mark there is a pointer THAT NEVER BUDGES (at least on mine). The manual says: "If the pointer moves onto the red line, the engine is overheating." So... um, the pointer stays put until and unless the engine overheats, at which time it moves to the red?? On a normal temperature gauge the pointer moves as the engine warms up. Not so on the F-Type? Or do I have a malfunction?

 

You do not have a problem. I thought I had one as well (also '16 V6S). Look at your gauge as soon as you start driving in the morning (typically I was way too excited to get driving to pay attention to the gauges). It takes just a very few minutes to rise from blue to EXACTLY the center line. If the engine was run previously during the day, it takes less than a minute to rise to the center line and not a micrometer beyond. That's some real solid temperature regulation.

 

That's how it is on modern cars, the temperature gauge doesn't move from exactly the middle until it's really hot.

This has been the case on Jags since the 90's. It sits in the middle of the dial from about 84°C up to 110°C or so... because seeing the needle move up & down could make people nervous, apparently...

There is an "upgrade kit" which was produced for the old X100 XK8/XKR and X308 XJ that converts the gauges to actual proper instruments, XK8 / XKR / XJ RealGauge - TheJagWrangler but there is nothing similar available for later models.

I did however come across a guy who wrote a modified software file for the instrument cluster in my Land Rover, that makes the gauge work correctly. (in the LR the temp gauge sits in the middle from 75° to 113°)

I asked Alex if he would be interested in writing new files for the Jags to correct this problem, but he is too busy and there would be some costs involved in reverse engineering, needing test vehicles, etc... it's not impossible but someone will have to fund it.

If you really want to see the engine coolant temperature then hook up an OBD reader, you get the true numbers via OBD.

 

Well, at least it's not a malfunction (silver lining, etc.). But lhoboy, we DO indeed have a problem. The manual insists that "at all times, not just during breakin, do not exceed 4000rpm until the engine has reached full operating temperature." How are we supposed to know when that occurs w/o a gauge telling us so?

Cambo: "That's how it is with modern cars." That's not how it is on the Mercedes SLK55 AMG (which I just traded in for the Jag). Its gauge digitally displays the degrees as the temp rises. The numbers blink until a temp of 176 degrees is reached, at which time the blinking stops and the car will allow high revving (not before).

This is a big disappointment. Stupid, as well.

 

It is obvious that us stupid Americans can't be trusted to either drive or interpret gauges correctly. Hence, the idiot gauges and offering only AWD Rs to us here.

 

It's not about "stupid Americans." Gauges have been disappearing on vehicles all over the planet.

 

Exactly. Not unique to Jag at all. Joe Average driver doesn't know how to interpret engine gauge readings. Actual malfunctions where the driver must intervene are now so rare that gauges are not of much benefit.

I would find a blinking engine coolant temp gauge very annoying. Hope Jag never adopts that bright idea.

 

As an engineer, I would pay extra for complete operating parameter readouts. Opted for additional OEM gauges for my MINI. Helps to forecast issues before they can cause a catastrophic failure, if one knows how to interpret the information.

 

I am hoping that some smart engineer will figure out how to get the engine info to display on the touch screen. They do it on Mercruiser's "smart craft" system for boat engines, by using the data from the OBD port or otherwise tapping into the ECU. Whatever they do it displays on the navigation screen, eliminating the need for the usual array of gauges and displaying fuel flow, oil pressure, volts, water temp, boost, etc. Maybe someone can copy that code and adapt it to our cars.

 

From memory, the oil pressure gauge in the R53 with Chrono Pack isn't connected to a pressure transducer...

 

Don't have the Chrono pack (GPS screen in its place). OEM gauge package only included oil temp and voltmeter. Both have proven useful.

 

The BMW 5 series I recently tested had an oil temperature gauge, but no coolant temperature gauge, just a warning light for that. All my cars to date had a coolant gauge or warming lights. So what's better? Do we need both gauges? Do we have a coolant warning light on the F-Type, or both, or what?

 

One water temp gauge that reads dead center if you are within a 35 degree acceptable range, and I presume all kinds of warning messages that flash up (similar to low tire) when you are overheating.

 

There are used to be aftermarket systems like this that could work with the F-Type. I haven't looked in a while though.

The issue with getting it displayed on the touchscreen is you need to 'tap in' with something like the Navtool JAGUAR NavTool video interfaces which will bring up the image to the screen.

But it won't give you touchscreen functionality for that image, just display only. Though it is possible to add a touchscreen overlay to the existing screen as well. A couple of forum members with older models have done this too.

Then you need to decide which device you use to get that info up on the screen. A little mini-Android-PC running an App would work, then you get the sensor data via OBD.

Or maybe there are some other black boxes which will do it. I haven't looked for a while... I think the Japanese Tuner crowd would have something available.

I guess the real question is what's this worth to you? I can imagine spending at least $1500 to get something like that up & running...

 

$1,500 would be fine. Maybe a heads up display projector would be easier.

 

Driving 90 on US 50 the loneliest highway in 102° heat for 400 miles & the gauge didn't move.
follow up: 106 in stop and go traffic on the I-70 headed towards Grand Junction, for about an hour... and didn't move.

If that image was just a jpg I wouldn't be surprised. LOL

 

115 today and in a trffic jam guage didn't move. Record hi but and draught but no climate change.

 

I have noticed on my new 2021 R that the temp gauge triangle indicator comes up to the dead center position pretty quickly from a cold start in the morning. Much more so than my Mazda CX 5 which shows actual temperature calibrations and takes a few minutes of driving before the needle is in the 210 degree F range which is its normal operating temperature.

I sure would have liked Jaguar to include an oil temp, oil pressure and amps gauge as part of the instrumentation.

 

By the time my temp gauge was in the red, I'd already received an extreme overheat text message on the console. Pulled over immediately. Cracked SC coolant pipe. Blown head gasket. I concur that it would have been nice to see it coming.

 

All the cars I've had recently, Corvettes, SLK AMG's, and a BMW Z4 had temp gauges that indicated the actual temperature. That's the way I like it.
