They both should feel warm or hot to the touch with the engine on. There are two hoses coming to and from the heater core. Heater core’s are typically pretty affordable. Feel your passenger floorboard to see if it’s wet. A bad heater core can also leak, so watch out for that. Without the warm coolant going through it, there can be no heat. If you have a heater core that clogged, it’s not going to be able to pass coolant through. Over time, they are known to clog and fail. If it looks like it is colder than normal, that’s a pretty good indication that there is something wrong with the thermostat. If your Equinox has a built in temperature gauge, take a look at it and see if it is in the spot it is normally in after a bit of driving. When this happens it’ll feel like the heat is barely working, or you may notice that it’ll work if the vehicle isn’t moving, but if you get on the highway it stops working. This allows the coolant to continuously enter the engine.
Sometimes when a thermostat goes bad, it stays stuck open. It does this by allowing water to enter the engine when it is getting hot, and by keeping coolant from entering while the vehicle warms up. The job of your Equinox’s thermostat is to regulate the temperature of the engine. Never touch the radiator cap unless the vehicle is ICE COLD. It should have separate lines to indicate “cool hot” and “cool cold”. The overflow reservoir will be connected to the radiator by a tube coming from the top (usually right by the radiator cap). You can verify this by checking the coolant level by taking a peek at the overflow reservoir. Is there isn’t enough line pressure, due to low coolant, then the heater core will not be able to get any coolant itself. While not having enough coolant may make your engine run hotter, it can also cause your Equinox to not be able to create enough heat. Anytime you’re putting your hand around the radiator or fans in the engine assume that they are hot and that the fans can kick on at any time, even without your key in the ignition. The exception to that would be when you would have reason to believe that the hose going from the reservoir to the radiator is clogged. There is almost never a situation where you would need to take the radiator cap off of the radiator to add coolant. If the heater has stopped working in your Equinox, this process has failed in one way or another.Ĭhevy Equinox Heater Not Working: DiagnosisĪ word of caution: If there is no coolant in your overflow, you can refill it by adding more to the overflow reservoir.
#2008 chevy equinox heater blows cold air driver#
At this point, the blower motor blows air across the it and the newly heated air blows on to the driver and passengers. If the heat is blowing, but blowing cold, it has something to do with the coolant getting to the heater core, or the heater core itself.Īt the simplest level possible, the heater works by passing hot coolant from the engine into a tiny radiator called the heater core. If it’s not coming on at all, it’s usually either the blower motor or some other wiring issue. Not having a functioning heater makes driving much less comfortable, and can be a sign of certain issues.Īt the simplest level, there are two main reasons why the heater is not working. I guess my question is.One of the most common (and inconvenient) problems with the Chevy Equinox is when it has no heat coming from the heater. The smell seems to be gone (possibly a little residual smell that will go away?).
No overheating and the gauge seems to be working properly again.īrought the car back and they were able to find a leak at the heater core, so now that's been replaced. Same problem (no heat when idling and smell of coolant). They also wanted to replace the dash cluster gauge for a ridiculous amount of $ (I passed on that for the time being). The mechanic's first solution was to replace the thermostat and flush the system. So, I brought the car in to get it checked out. When the car is off, the gauge would only go back to about 50%. Also, the temperature gauge on the dash appeared to "stick". Recently, I was getting overheating messages on the dash, but when turning the car off then on again pretty much right away, the message went away. There was also a strong coolant smell when heat was on. My 2008 Equinox had not been getting heat in idle, but heat would come on when driving.
