It is hot and the low coolant light is on, two clues that your coolant is disappearing. three places for it to go. 1) into combustion chamber will cause rough running, white exhaust, and coolant smell at exhaust pipe, 2) into lubrication system, pull off your oil fill cap and look for foamy **** in hole or on bottom of oil cap or on dipstick, 3) outside engine and you will find coolant puddles where you park. coolant is generally green or orange/brown these days. also generally will be stains on the engine where the coolant leaks down and off.

first two mean a bad gasket or crack and will be expensive. last one means someone has to find the leak and stop it. if your interior stinks and your passenger's feet sit in a slippery wet spot, then the leak is in the heater core, that will not be cheap.

1998 Lincoln continental low coolant level added coolant and coolant level warning cleared know car is overheating even after bleeding air


There are electric cooling fans which have Relays and the fans themselves can break. These are triggered by separate heat sensors other than the one that controls the dash indicator.

Once you add coolant, if it stays full, you are okay for water volume. But water alone does not cool the engine. The electric cooling fans are just as important.

If the coolant level drops again, there are 2 potential problems for the loss. A leak or boiling over. You can tape a paper towel around the overflow tube discharge at the bottom of the car to verify that the water is being lost out the overflow.

Another thing to consider is that the cooling fans may have 2 speeds and high speed may not be working.

I have a 2001 Buick Regal. The light for the odometer is not coming on for a couple of months now and 2 days ago the light for the a/c controls is not working. Yesterday the low coolant light started...


it is probably just a burnt light on the dash for the a/c and the odometer, as for the low coolant light if the car jhas more than 100,000 miles on it you need to get the coolant flushed that is all the light is warning you about.

99 Firebird still overheating after repairs and antifreeze


overheating is most likely a bad thermostat, but the coolant loss is a second big concern. Does the exhaust look like steam? You could have a cracked block and the coolant is leaking into the engine. Also check the oil for contamination.

Replace the thermostat, if that does not cure the issue you have a slight head gasket leak. I am a retired Ford dealer tech and this is what I have found causes this issue.
