Answer 1

The A/C uses coolant gas (gas from the engine coolant), so the two problems are probably related.



The Chevy Malibu uses recommended green coolant, so you may have the wrong coolant filled in the resevoir. Check the color of the coolant, and if it is yellow, you probably have a leak in the hoses.



The lack of leaking when parked in your garage indicates a moving fluid, such as the coolant.



Alternatively, it could be the gear fluid, but it's unlikely as you should feel performance loss.

If the leak is slightly oily and yellow or green then it is most likely a coolant system leak. Look for a small black rubber hose attached to the top of the radiator, follow this hose to the coolant recovery tank. If the coolant recovery tank is empty then you have diagnosed the problem. Have your mechanic pressure test the cooling system to pin point the leak. If the leak is clear and oily it is most likely brake fluid. You will have to touch the fluid with your fingers to determine if this is oily. These leaks are most commonly found near one of the wheels or directly under the area by the brake pedal. These leaks should be taken very seriously as they can lead to brake failure. Have your mechanic check your brake system for leaks. If the leak is clear but not oily there are two possible sources. You will have to smell the fluid to determine if this is water that has condensed in the air conditioning unit or if it is windshield washer fluid. If it is windshield washer fluid, fill your tank and watch for drips. You can have leaks in the hoses or in the tank itself. Remember, you car may run with low or no fluids, but very expensive damage can occur. Take the time to prevent a costly repair by taking it to a mechanic

Answer 4

95 per cent of the exhaust systems built today are made up of iron alloy and galvanized steel. Exhaust pipes are made of either iron or stainless steel. Heat shields are made of galvanized steel. Galvanized steel uses zinc as a rust inhibiter.



Zinc, when hot and in the presence of iron and a catalyst, creates yellow green zinc oxide in the form of crystals. The connection is the catalyst - salt water - or compacted snow with road salt mixed in. If the snow is able to touch the exhaust heat shields and the exhaust pipes at the same time, the chemical reaction between the two dissimilar metals creates the bright neon yellow green crystals.





As the hot exhaust pipe(s) melt the snow, the neon yellow green substance drops to the snow covered ground - causing much consternation.

Did you ever find out what it was? I have a 2006 Impala that I just noticed the SAME thing today in the snow... bright yellow and not a large amout... I do know that the coolant in My car is Dex-Cool which is orange ... so not that

Answer 6

Most likely radiator coolant. When you were driving in high snow you probably loosened a O-ring clamp around a hose or the lead hose that goes to the water pump.

Answer 8

sounds like coolant to me. especially since your ac doesn't work . take it to a repair shop and have them take a look. it could be something as simple as a loose hose clamp or bad o ring caused by contact with the snow. good luck.

Answer 9

Bright yellow? sounds like a gas leak.

Maybe that's true
