Coolant level the coolant level is not getting down since one year in my GMC ENVOY 2003. is ot normal?

YOU MAY HAVE A THERMSTAT IS THE STUCK PARTIALLY CLOSE
NOT ALLOWING FULL FLOW OF COOLANT THROUGHOUT ENGINE, TRY TO REPLACE THE THERMSTAT. WHAT ENGINE IS IT? 4.3L,5,7L ?

Modern engines run at high under hood temperatures. If the temperature gauge is running normal and there is no signs of steam out of the water bottle, there should be no problem, but keep an eye on the coolant level and check the engine after a long slow run if you are still worried.

There is no adjusting or tuning to do,for the last 25 years,the computers etc, do that
60,000 is long enough for spark plugs
You should have flushed the brake fluid, every two years
Coolant every three
Trans fluid and power steering every ,three or not more than 30,000 miles
Fuel and air filters every three years 30,000

The cooling system in your vehicle is filled with DEX-COOL engine coolant. This coolant is designed to remain in your vehicle for 5 years or 150,000 miles (240 000 km), whichever occurs first, if you add only DEX-COOL extended life coolant.

A 50/50 mixture of clean, drinkable water (if the water in your area is of poor quality, it is recommended you use distilled or de-ionized water) and DEX-COOL coolant will:

• Give freezing protection down to -34°F (-37°C).
• Give boiling protection up to 265°F (129°C).
• Protect against rust and corrosion.
• Help keep the proper engine temperature.
• Let the warning lights and gauges work as they should.

Hope this information helps

heres a diagram to show you where the coolant temp sensor is located, its behind the alternator on the left side (driverside),the sensor just unplug the connector and then unscrew it and out it comes.

If you are getting the low coolant message you are looking for the coolant level sensor not the coolant temp sensor. I do believe the sensor is in the jug, is it filled to the full line?

I would look into a tune-up as the spark plugs are a common cause of issues on this vehicle. I would at the very least remove the plugs and inspect them. If they are fine then it may be a clogged fuel filter.
Check the coolant and oil level

maybe the same problem, if its not getting to 195f its not enough.

u have to take your dashboard at the glove compartment to cheack the vacuumpod ot your damper door

That code represents a lower than expected reading for temperature (coolant). First thing to do is check your coolant level, as if it is low, then the sensor can not read correctly. Second, you may have a thermostat that is stuck open, allowing the coolant to cool off too much. The sensor should be mounted on top of the engine, near the thermostat housing.
