Does anyone know how to check the coolant level in the G37 coupe? I was told to look at the reservoir, and coolant is there between max and min. I drove the car a lot today, and let it cool off for like 5-6 hours, and the reservoir level went up a lil past max, and when I opened the cap on the block I seen no coolant.
I started the car with the cap open, and I seen the coolant rise up. I already got the car pressure tested, and bled using the little bleed hose in the back before and when I would check the level on the block is was fine for a couple days, but now I don't see any coolant or little coolant in the block when I checked in the morning I droved the car anyways and it was fine only because the reservoir wasn't low. I don't know how these cars work (only had the car for 3 months and has been dealing with this) thats why I'm on here because I don't want to ruin my car. No overheating issues either. All I know is previous owner replaced radiator and thermostat.

Sorry if I'm not making any sense.

 

the owners manual tells u

 

Coolant level will adjust in the reservoir tank but should remain full at the radiator. I keep mine right in the middle between Min & Max at the reservoir when cold, and it's always stayed at that level (and the radiator is always full).

Might be a problem w/ your radiator cap (hopefully).

 

I changed my cap maybe two month ago but Maybe it's defective I would hope since the shop said I'm not leaking after the pressure test.
