what is the greenish fluid under the car?
Hi guys, over the last month seen a few drops of a greenish fluid under the car. Today i noticed a bigger ammount on the floor about the size of a post it note.
Any ideas on what this fluid is and where it’s coming from. I have attached a picture below Thanks in advance |

Coolant is blue but that looks like a mix of oil too. Power steering fluid is also typically green for the CHF fluid.
Looks to be more water consistency so my guess is coolant.

Yes your right I also noticed oil drops in another spot, but they weren’t mixed with green fluid. It believe the vaulve cover gasket has a decent oil leak but the greenish part I m debating between power steering fluid or coolant as you said. Thanks for the prompt reply |

The CHF11s PS fluid is green when new, but not blue-ish, plus it gets more brown (dirty) pretty quickly, so a vibrant green-blue like this has to be coolant IMO. The brake fluid from my P.O. was green, but a strong green like the PS fluid, not blue-ish at all. A coolant leak is certainly a concern, and even moreso if mixed with oil, but hopefully the mixing happen once it left the engine.

Looks like coolant, not the hydraulic fluid from the steering system.
