Coolant level inside reservoir?




The extra coolant may come out when the system pressure reaches the maximum pressure the cap is designed for. Hopefully it is not too dirty and stain around the reservoir.












In a proper 50/50 mix, I never loose coolant more than few millimeters depth in 20,000KM, which include 120C coolant temp at the track ( fun drive ).
If ever you remove coolant from the system, real topping up need some drive cycles....takes time to burp all the air out.




Then, the extra coolant should have flowed as soon as the floater went up. Wonder why he did not see coolant under the car already.

That's black and white plastic meeting on the reservoir is the gauge I use as well when topping off the coolant.

Mine are over 10 years old but still look / feel fine (at least on the outside).
Replacing them next week (regardless of outer appearance) due to age.
Might as well since I'm changing the coolant anyway...




FCP Euro has them so I'll go that route.
Thanks!
