A couple of thoughts. You have typically two temperature gauges on the regular display: one is coolant temperature and the other is oil temperature.

As shown here in this 2014 dash. The oil temp is the one next to the tach and the coolant is the one on the lower right.

You can view additional digital gauges at any time by switching to the Performance display. Regardless, you should have no digital/analog display that registers zero when the engine is running. In fact there is no zero demarcation on these gauges. If both the oil and coolant are at "100" it sounds like you have either a fuse out, sensors that have failed or other issues.

 

As a followup, I had my local mechanic do a diagnostic reading and it threw a code for the thermostat and an intermittent coolant temp reading. I did notice the analog temp gauge fluctuating in it reading between 100 and 220 during the last 2 drives I took and then a total failure to register any reading on the last drive So, I'm having him replace the thermostat and the coolant sensor at the same time. Not a very expensive fix. I am happy to know that the oil temp never reached a high reading and also happy that the coolant fan running several times for the 18 min timer coupled with the factory battery tender that the lowest my battery reading got was 11.9 volts. Even though this is a "new" used car, even having an issue right out the gate I'm very pleased with the quality of the car and I believe it's going to be a keeper.


Thanks for replying to my posts. This corvette newbie needs the help!

 

I am not talking about the oil temperature gauge, that reads normal. The coolant temperature analog gauge on the right bottom indicates 100 and never moves from that. It did the first drive I took and most of the second drive that I took yesterday and then stopped indicating normal coolant temp at right around 220. The digital gauge under performance data only shows an engine temp and that reads 0 degrees. I know that the reading is not right, because the coolant in the overflow tank feels warm to the touch and I believe the engine temp should read around 100 even when the motor is cold. The fuses are so cryptic that I can't determine which is for specifically the analog gauge. And I have no other issues with the cluster as in the engine light or any overtemp light. I believe it's the sensor, but I was hoping the troubleshooting would be kind of cut and dry. If you know what fuse is for the coolant gauge, I'd be happy to know. Thanks for your reply......it's pretty hard to find specific information online.

 

I've been digging through the threads here and I have found a bunch of good info on the issue I'm seeing...... There is more information here than anywhere I've seen so far......thanks for that!!

 

Glad that your mechanic was able to diagnose and fix the issues and especially, that you are looking forward to enjoying the C7!

 

You will find that the major of us are very pleased with the quality. I also have a 2014 Z51 Stingray and it has never had any issues that required repairs for a 7yr old car.

Glad that everything worked for you and although there are no perfect cars, I am sure that you will have a great owner experience.

Oh, and welcome to the forum where there is a vetteapedia of information from the members and search box.

Hey Kyle - I have a 2014 "daily driver" C7 with about 60K on it. Yes, having had a couple Vets, they can be enjoyed as daily drivers year round in California. Looks and runs beautifully!

Now to your temperature issue. I had the same problem. I asked my Corvette expert in my area to take a look and he replaced a thermostat that was stuck open and the temperature sensor that also went out. Go figure, both at the same time. Luckily, he replaced both during the same service and gave me deal. Ever since then, everything is perfect! The temperature runs consistent and the fan issue went away. It's important for C7s to run at the correct temperature!

Enjoy the Corvette experience. Stay positive and test negative!

My mechanic found the same thing. Just pulled the car into his shop and he'll be changing both the thermostat and the coolant sensor. I should be back on the road tomorrow. Thanks for the reply! I'm excited for my first road trip coming up in a week or two. Depends on whether the pass going east is clear of snow and ice. So far, it's dry pavement.

Drive safe!

 

About the cooling fan running for 18 minutes... is that after parking and shutting off? In over seven years of ownership, I have never heard my fan running after parking? (non Z51, manual)

 

Hi Autoxal,
The fan will continue running after turning the car off for 3 reasons: 1) The thermostat has gone out. 2) The temperature sensor has gone out. 3) Driving the car hard or in hot weather and the car needs cool down. Absent those 3 circumstances, the fan will not continue running after turning off the car. The fact that you haven't had issues 1 and 2 means you are good to go. If the issue does occur, rest assured that many of us have experience it, the fix is quick and not very expensive.
Thanks, Gene

 

Not that my memory is 'perfect'... I can't even remember hearing any cars at the Ron Fellows - Spring Mountain school with their fans running after track sessions (temps in high 90's)? During the open lapping, day three, I did have a couple occasions to feel the car I was driving "back off" power when engine temps started getting out of range high. ????

 

They probably were out in the open where the car could not impact the ambient. My garage does not have AC. Parking the car in the garage has a noticeable short-term impact on the temperature in there.

 

Im having the same problem..What did you do to fix that. I replaced the sender by the thermostat, still the same problem
