no smoke (anymore )
no oil in coolant
no coolant in oil
no puddles on floor
i think i might need to replace rad cap? would that help
No there are no fill lines but typically if there is ANY coolant in the overflow when you undo the radiator cap you will be able to see coolant. At any rate the level in the overflow wil vary depending on conditions. How long has this problem been going on?ifoam said:overflow, i dont see any "fill" lines on the radiator
cant smell any coolant. no leaks underneath. its gone down half an inch over about 2-3 days.0341TODD said:can you smell coolant? is there ever any leaks underneath the car? How many times have you seen that it was low and then filled it back up again? Does it happen regulary or is it over a long period of time?
I dont know how cold it gets where you are at but with cooler weather I have seen a drop in my coolant level. It wasnt enough to make me think that I had a gasket problem as the coolant still held good color, did not reflect and had no particles in it. To be on the safe side, I bought a NISMO cap rated to 1.3 bar (IIRC on that rating) just in case the seal was not perfect. A cap can cause gradual coolant loss. Also, IIRC the NISMO cap fits any Nissan.wes said:If that is the extent of how far it has gone down I would not worry. It is perfectly normal for that level to fluctuate.
You have to fill the radiator and then bleed the system to remove the air. If you didnt do this then the level going down might just be escaping air being replaced with fluid. Also the level will go up and down with temprature of the engine/coolant. Look at the hot and cold lines on the coolant bottle.ifoam said:overflow, i dont see any "fill" lines on the radiator
