2010 Malibu overheats and uses coolant without any visible leaks. 3 GM dealers have not tried to solve problem. Can only drive 50km before car overheats. Help!

Do you see a lot of white smoke rom the exhaust? If so, Head gasket. Check to see if the oil & coolant are mixing together, (ck the oil for coolant & the coolant for oil) . Its got to be going somewhere. Do you see any puddles after parked? SPEAK TO MANAGEMENT BEFORE YOUR WARRANTY EXPIRES. Good luck.

Antifreeze leak in 2005 Chevrolet Equinox, how much to fix.

Hi, if you have searched this problem recently on this car you will find that there is an issue with this particular engine (3.4 litre) that GM used on various vans and SUV's and the DEX coolant that is reccomended for this engine. Apparently the coolant corrodes the aluminum parts (intake, gaskets) causing them to deteriorate faster. I have had the unfortunate experience with this issue. First it was diagnoised as a cracked lower intake- car was leaking oil. Had that fixed but overheating issues persisted. Tried flushing the coolant but that only solved the problem for a few weeks and overheating started again, and coolant was boiling over in the reservor. Finally took it to GM (was having my own mechanic fix it prior to this) and they just called to say the gaskets are leaking into the combustion chamber and that is a $2000 (canadian) job. IF they find that one, or both the gaskets (there are 2) are also cracked (unlikely that both would be cracked) it is a $3000 job. I am considering trading in my car to the GM dealership. Only offerring $2000 for trade in as is. My advise is get your car to a GM service shop so the problem is properly diagnosed. I was told that I may have had this fixed under warranty if my vehicle dd not have 176,000 KM on it. Not sure if this is BS. Please connect with me here and let me know of your progress. I am stuck without a car and have a huge decision to make. I have been on tons of forums and there has not been one concrete solution that I found prior to taking it in to GM.

My Ford Taurus 2002 has a blinking engine light. Also, the coolant has a leak. My mechanic says there's a leak of the coolant that is going into the engine. Just to see where the leak is happening he...

well, coolant mixed into your oil is terrible. it breaks down the oil.Before you do anything expensive you could try GM cooling system sealing tabs. Or another off brand from a parts store. GM came out with these tabs when they realized they had weak intake gaskets in there vehicles. They seemed to work rather well. Just because they are a GM product doesn't mean you cant use it in other makes. And change the oil as soon as possible! maybe a couple times.

What type of coolant to put in

50/50 antifreeze and water. pontiac or GM recommends the use of Dex cool antifreeze but it really doesnt matter. You have to check the color of the coolant orange you need to use extended life, if its green just use regular 50/50

I have a 2004 Chevy Impala. I just recently noticed that I have heat while the car is moving but once I stop at a traffic signal the heat goes away and the water temp goes up on the gauge.

Check your coolant level. This will happen when air passes through your system; the engine will heat up rapidly, and the heater will go away. You do not want to run it that way, otherwise you'll be dealing with severe engine damage. If your coolant level is good by chance, you may have to look at replacing your water pump, thermostat, or both, but I'm confident that your are dealing with a coolant issue.

I own a 2000 Cadillac Deville and the low coolant light keeps coming on but when I check the reservoir, it is full. What should I do to correct this problem?

I had the same problem and they suggested that I add GM tabs to the collant system to keep it from and very slow and tiny leak. They added the tabs and the low coolant light stopped.

hello there

there are two types of coolant that were used in your car: your coolant bottle or cap may have a orange or green dot on it.

Orange dot = DEXCOOL
Green dot= Eythelene gycol (green stuff)

All the 97' and UP had dexcool. 96' was the transistion year, some one way some the other.

Hope this helps. Please don't forget to rate me.
