    Never any leakage, I'd know I keep it in a garage every night. It shows low on coolant about once a month, and i usually have to add about half a gallon. I only drive it about 300 miles a month.

Hi and welcome to FixYa!

You may have a faulty radiator blower motor. If the blower blows weak it will surely be not enough to make the engine cooled down. One good reason the water boils on the bottle. Another issue can be a clogged radiator and a faulty water pump. These can make the engine hot too when faulty. Please give enough attention on the possible causes to prevent severe damage to the truck.

Hope this helps and thank you for using FixYa! Have a good one!

One of two things has happened. Either your coolant has gotten really low (easy enough to check) or you heater core is starting to plug up.

Why does my 2004 avalanche not heat up when i am


Check the coolant level. in the winter time It will not over heat very easily but vapor locks can occur and low coolant level will do what your describing ...When you drive the water pump is spinning faster causing coolant to intermittently flow through the heater core so it gets warm then cold at an idle.. also a thermostat that is stuck open will also cause this its also in the cooling system, if the cooling system is full I would replace the thermostat..good luck hope this helps

Low coolant light


Have the car put on a rack and look for a white powder, this will be the residue left by the coolant leak, if you find nothing then pressure test the system and look for a pressure drop after a few minutes, if you have a loss of pressure then the system is leaking, if there is no sign of the leak then it is going inside one of the cylinders.
