Low Brake Fluid Warning
Weston posted a question in Ask the GM TechnicianMy warning lights come on when temp outside is in the 40’s and below. It says “ Low Brake Fluid, Stabilitrak Off, Traction Control Off” and this morning it also said low coolant. I live in south Florida so this happened last year when I went to Ohio in December, the truck had 12,000 miles on it. Got back to Florida and it happened one cold morning so I took it to dealership. They could not find anything wrong. Later with 38,000 miles the low coolant light came on. I took it to dealership again, they could not find anything. Now I am back in Ohio for Christmas and the lights started coming on again when I got into colder weather. They do go off at times while driving but come back on within 10 minutes if the temp outside is still below 40. It is very annoying as the warning bell starts going off and the lights flash. Any advice?
A few weeks ago, my thermostat in the radiator was replaced. Ever since, my dash now says "low coolant" even though the coolant level is fine. I can't really find anything on other forums, so here I am... Any suggestions on what it could be, or needs to be done? It's a 2012 GMC 2500 Denali, diesel. I'm not super car savy, so if you can "dumb it down", help a girl out, I'd appreciate it! lol Thanks! Also, posting this in multiple forums... hope that's not taboo...
Coolant changed, and then...
brainpause posted a topic in 2000-2014 Silverado & Sierra HD2001 2500HD 6.0 Took my truck to a national chain that I've used before and Trust. Never mind which one. Had the coolant changed and some other front end issues worked on this past Saturday. When I left it was a little warm so I was running my air conditioner. Then yesterday it cooled off quite a bit so I turned on the heater and a few minutes later the low coolant light came on. I started to drive home anyway thinking it was maybe just a little bit low. But I hooked up Torque application using my OBD2 diagnostic in the coolant temperature was steadily Rising. I decided to take my truck back to work and drive a work truck home. Here is where I admit some ignorance about the procedure and I wonder what might have happened. When the coolant is flushed, aren't they supposed to run it through the heater core somehow? Or maybe they did and then it had an air bubble in it and so it didn't fill the heater core? Or maybe there was a very large air bubble somewhere else in the system? I did check the Overflow container and it looked empty but it was dark. The engine was fully warmed up. So what could have possibly happened or what did they forget to do? Or maybe it just needs a little more coolant?
Low coolant light
Cdigiorno posted a question in Ask the GM TechnicianAt random times my "low coolant" light comes on. The temp gage will show around half way 220 I think. Just had the oil changed and everything looked normal. I check the coolant and it shows normal. Any idea. 2001 gmc sierra 1500.
