Why does my car coolant have a gray color?
The coolant can’t do its job if it’s mixing with oil and its cooling properties are compromised. The exhaust exhibiting a gray or white color is another sign of coolant leaking into the combustion chambers.
Why is my car’s oil cap milky white?
I checked my oil today, and the cap is milky white, which would lead me to believe it’s the head gasket. When checking the dipstick, it is normal oil colored and when taking the radiator cap off to check for bubbles, it is normal coolant colored with no bubbles. Please advise. My car has 160000 miles. My car has a manual transmission.

What does it mean when coolant is leaking from your car?
Coolant: This comes in many fluorescent colors, and can leak from many places throughout your cooling system. Coolant has a sweet odor and a slimy texture. Losing coolant will lead to overheating if not addressed, and if the engine overheats, you can be left stranded and with a huge repair bill.
What happens when the coolant level is too low?
Once your coolant level gets too low your engine will start to overheat which can lead to significant problems. Overheating can lead to further deformation of your cylinder head or engine block as well as other leaks in your engine from excessive expansion and contraction of components.
What causes coolant to bubble in the radiator?
When your engine is running, the high pressures in your combustion chamber can push exhaust gases into the cooling passages causing coolant to bubble in the radiator and pressures to get so high that coolant will actually be forced out of the coolant reservoir.
