Hello. I have Mercedes S320 (2001). It's cooling fan doesn't start working until it's about 93 degrees. Is it normal? Also there has been no water leakages but it's coolant box still decreases water.

first check your water bottle/radiator cap, and yes 93 is just about normal so its fine

@schalk, dear bottle cap seems okay as there isn't any leakage from there. But i don't understand why it throws water with immense pressure from the waste pipe


there is a valve in the cap, replace the cap
