To completely remove old coolant, there is a fitting available from parts stores like Autozone or Pep Boys that is inserted into one of the heater hoses that is shaped like a T. Follow those instructions, remove all coolant by flushing until coolant comes out as clear water. Cap up the T and refill with fresh coolant.In reality coolant flushing is overated and in my opinion just another expensive myth perpertrated by repair facilities. As long as it tests to -10 degrees I have never flushed my Ford F150 and it has over 300,000 miles on it with no coolant problems.

Added wrong coolant 50/50 to my 2001 grand am what will happen

Hi Damita:
Shouldn't be a cause to be overly concerned.
My questions to you:
- Why did you have to add coolant, and "just because it was low" is not the answer.
- What kind of coolant did you add, and why do you think thay it is wrong?

If the engine overheated and that's why the coolant was low, we should be trying to discover why the engine overheated. Things like Bad Water Pump, blocked radiator, bad thermostat, blown head gasket.

The coolant level is the indicator that something else could be a problem.

Hope this helps.

Rear heat is not working

Coolant is the carrier heat to the heater core.

Check your service record for your last coolant and thermostat change. Recommended service interval is every 2 years.

99 gmc suburban's oil is light brown, had no coolant

Well if the coolant escaped and there are no external leaks, something happened to the cooling system to let it into the engine oil.
Either a head gasket, intake gasket, or some other engine failure.
I would probably notify the shop that did the trans service just in case it was something they did.

Where is the radiator drain plug?

Not all vehicles have them any more but if present, it will be on the bottom tank of the radiator itself. It costs a buck or two to provide them so they are happy to let you rip the bottom hose off to drain coolant. BTW, use something to collect the draining coolant; if the typical glycol, it is sweet and animals will lap it up prematurely ending their lives. Many service shops will accept old coolant for disposal.

My car said I need coolant do I take it to the dealership or can I take it to a local gas station?

Adding coolant is something that can be done by anyone including you. Open the cap on the system and add coolant while the engine is running, 'till it reaches the full mark, then replace the cap.
Don't ever open the cap if the engine is hot. Berst to use pre-mixed 50/50 coolant or buy a gallon of 100% and split it between two containers making two gals. of 50/50.
It is important to know where the coolant went. If you see any dripping where you park, most regular service shops can often help, especially if the leak is from a hose etc. If the leak is from a major component, I'd have the dealer or a Mercedes specialist work on it.

When I turn on the AC warm air blows through and never changes unless it's cold outside. Do I need to fiil or replace something?

Most probably just needs to have the AC serviced and refilled with coolant. Since the car is a '95. I had to bring in my to get the coolant refilled just a few weeks back and it is a 2004. We used to just call it a freon refill, but they don't use normal freon anymore, they use a coolant/refrigerant that is safer for the environment, but this doesn't matter for you. Just bring it in to your mechanic or to your dealer and have the AC serviced.

They should probably put in a dye as well to see if there is a coolant leak, If so, it is usually a very slow leak and repairing the whole AC unit wouldn't be worth it. Either way, it needs a fill.

Good luck!

I have a 2000 Saturn L Series and the other day my daughter was waiting outside of the store and all of a sudden she heard a gurgling noise followed by a clacking noise like something was loose in the...

Check your coolant level and see if you can find any coolant leak. Don't check the coolant level in the radiator when the engine is hot, open the radiator cap and refill with the recommended 50/50 mix antifreeze/water. It sounds like your low on engine coolant and there is air in the cooling system. Once you have topped off the radiator, place the radiator cap on the first click and run the engine with the heater on the highest heat setting and make sure the over flow coolant tank is filled to the full mark. This will work the air out for the cooling system, after you have done this. Just close the radiator cap to the seconded click to ensure it's closed, but be careful the cap will be hot. Good luck and keep me posted. Note the coolant has a life expectancy of 150,000 miles or 5 years, so if the coolant has never been replaced. You may want to have the coolant flushed and replaced and the thermostat too, but if finance and time is an issue. Just do as mentioned above and service the coolant system in the spring, just before the summer.

Hot air does not come inside the car. It blows cold air only.

First check for coolant leaks(under the car,chech the radiator hoses and heater hoses) particularly under the dash.(this is something you wouldve smelled)If you find coolant under the dah inside the car your problem is the heater core.Next check coolant level.If low add coolant water mixture (50%water/50%coolant) If all this checks out your problem may be the heater bypass valve.It's a disc shaped control valve located on one of the heater hoses.It's a very cheap fix by any "honest"service shop

Bad coolant sensor flashes on the information display

Take it back to the dealer and then have them check the computer to see if something else comes up. But this is not right that they did not solve the problem. Insist that you get some concrete service and a better answer. The '90's were not the best years for the Grands and there were recalls. The VIN should be checked to see is there were prior recalls.
