It sounds like the approach to solving your problem so far hasn't been very systematic or "evidence based" – at least the list of parts replaces suggests that the people working on it have been using a "shotgun" approaching, replacing parts in hopes that one (or more) of them will solve the problem. Start off by doing basic checks: Is there hot water ...

Any chance the coolant wasn't filled completely and burped? The heater core is the last thing in the system getting coolant as it sits the highest. Also make sure there isn't any air trapped in the system. Use the bleeder screws (open them slightly) and squish the hoses. As has been suggested elsewhere, you told us all the repairs that were done, but not ...

If you have a confirmation that the head gasket is going bad. There is a product that states that it has the capability to fix head gasket leaks, you can give that a try(I have never used it personally). It is called Steel Seal, there are a lot of videos on the You tube about how to use this product, give it a try and write a followup review so we too will ...

It looks as though you could add a third party CarPlay-compatible receiver to your vehicle. A quick search on the Crutchfield site shows me at least 50 options. Even if you do not choose to purchase from them, their site is a great source for market research. Full disclosure: this is what I did on my 2004 WRX and I used a receiver from Crutchfield.

There's a few things going on here: What's a tune-up? Most cars built in the past 25 or 30 years don't need a tune-up anymore, as most of the engine management is now taken over by computers and sensors instead of spring tensions and adjustment screws. So when you said you got a tune-up, what did you really get? Vehicle ageing I own 4 vehicles, the youngest ...

They got over on you. You can utilize the red, orange, blue, green, purple, whatever color of coolant. The deal is, if you do use green instead of orange (Dexcool), you need to follow the change intervals for the green coolant (IIRC, it's usually 24k miles or 24 months ... depending on the brand, but I believe that's about nominal). The alternate colored ...

This feels like a broken blend door. A blend door controls how much air is allowed to flow past the heater core, or past the a/c evaporator. A broken door means that air physically stuck going past the heater core, thereby heating it up. Unfortunately, those doors live inside of the heater box, which usually requires you to rip apart the dash (and then ...

The reason this occurs is to take care of the humidity in the vehicle while your defroster is running. MANY older vehicles have this as a common function when your defroster comes on. It's odd though that the temperature setting doesn't change your AC temp. Chevy's 2011's were all CAN BUS computer controlled systems, it might just be a glitchy computer issue....

You will need to remove the airbox and the plastic cover over the valve cover to gain access to the CPS and actuator. The cam position sensor and actuator are located on the top of your valve cover to the left of the number 1 spark plug. From there you can remove the wires to the CPS and the actuator and have access to remove and replace them.

You will need to replace the entire switch assembly. Replacing the switch should not be that difficult. You should be able to do this by: Remove the steering column trim covers. Disconnect the multifunction turn signal switch harness connectors. Depress the lock tabs on the multifunction lever. Remove the multifunction lever. Replace in reverse. You ...

From your description and comments, I'd suggest you have a dead spot in your Throttle Position Sensor (TPS) right after idle (low end of the throttle). If the TPS is not reporting the correct throttle position, the computer will not lengthen the pulse width of the injector to give the engine more gas, which will in turn cause the engine to die. If you get ...

You can fix this yourself with some sockets, a wrench, a torque wrench and probably about 200-500 dollars in work and a few days wait that most machine shops will charge to restore a busted head. You'll need about a hundred bucks to get a new gasket and you'll probably need a good weekend to take all the manifolds, wires, injectors and hoses off the head and ...

P0420 is probably the most common code seen. It refers to "Catalytic Converter Efficiency" Basically, it Engine Control Module (ECU) monitors the chemical constituents of the exhaust, both before and after the catalytic converter. The Catalyst is really a small furnace that reburns the exhaust and adds more oxygen where necessary, to eliminate harmful ...

There is actually a letter that was sent out (I also have a 2011 Chevy Equinox with this issue and just had my cat. conv. replaced because of it) saying there may be thermal damage or melting on it and if you have this issue to take it to your dealer to get it repaired. Did you get that letter?

You need to confirm where the leak is coming from. Make sure it's not coming from the water pump gasket. If it is there are products available to help with water pump gasket sealing. Make sure the intake gasket isn't leaking. IIRC on some 3.4l engines, there are plastic coolant elbows that crack or go soft and break. They go from the alternator bracket to ...

You're not going to be able to buy an airtight vehicle. That would be dangerous for multiple reasons. There are a few possible explanations for dust "pouring in" to your Equinox, such as loose door seals or a loose or damaged cabin air filter, but the biggest source of dust is almost certainly opening the doors after stopping. When you have just stopped, a ...

It looks as though there's just a bad scuff on the rim. As Spinovious said in the comments, if it will hold air, it's probably good. Since this appears to be a cast aluminum rim, I'd suspect it would crack/shatter before it would bend. Once the tire technician gets the old tire off, they can spin the wheel and see if there is any distortion. I think that's ...

The equinox of this year are a bit odd, is it a used ECM or new one? For the most part you are not be able to reprogram used ecms of this type unfortunately because the way the VIN and security data is stored. Basically, you can not rewrite it. Even if you had it flashed you will see it still has the ecm's original vin. You will need to buy a new one, ...

High humidity can condense then freeze on the evaporator coils more readily than dry air. This blocks the air flow . To avoid this keep fan on high with all vents open. Possibly, from the accident, there is some distortion to a vent that restricts air flow, to or from the coils.

Welcome to the site @Gina. This sounds like it could be transmission related, it's not switching gears when it needs to until it has warmed up. That could be due to the fluid being low (more likely being old) or there being a problem with it. I'm not familiar with the Equinox and whether it's possible to check your transmission fluid yourself, I'd suggest ...

There are differences in the coolants, see the link (not the only one and there may be better) : http://www.elf.com/en/advice-corner/coolant-and-antifreeze-faqs/antifreeze-types.html The choice is down to the metals that are used in the engine (aluminium, cast iron etc).

You need to raise the front end of your car and open the coolant reservoir cap (not the overflow), make sure engine is cold or the coolant will blow out and scold you, but what you're looking for is basically air in the system. Even though the coolant level may seem full there may be air trapped in the system. To get the air out you can turn the engine on,...

It could be connected, but without knowing what the code is behind the check engine light (CEL), there's no way to tell. That said, I'm doubting the two are connected. If the dash readout told you specifically the gas cap wasn't tight (or isn't sealing), it would have either continued to tell you the same or would have turned off if it is re-secured. If it ...

Kind of sounds like the impeller of the water pump is going and needs to be turning at a pretty high speed to get enough coolant circulation.

The upper heater hose has a T and there is a restrictor in it. Its plastic. Drill it out to 1/4" and that should help get rid of the air lock in the heater core.

It can be many things I mean, way many things, as SteveRacer has already cited. The most common (but not unique) is a failing catalytic converter. Please note that often a bad catalytic converter usually is a symptom of a problem, not a cause. If you replace it without solving the source problem, it will fail again in very short time. If this is the case ...

This sounds like a stuck or faulty heater circuit valve. There's a pipeline from the engine coolant system that goes up to a heat exchanger in the air conditioning duct. There's a valve that regulates how much hot coolant flows in this circuit, and if that valve sticks open or its actuating linkage is broken, the system will be on hot, hot or hot - No matter ...
