Heat Vapor - Related to Radiator?
Hi guys, although I am thinking this could not be a problem, but then again I am not sure about it. I have two questions and it maybe related to radiator coolant, not sure. So, please read a little background to understand what I did, and hopefully nothing wrong. I was trying to fix the faulty Auxillary water pump on my E60 M54 2004 model which was faulty. In the process I drained the old coolant out from engine block (PITA to reach the drain plug) and the radiator. Fresh coolant from Febi Bilstein (BMW OEM) was filled at 50% concentrate. After venting and refilling, I only filled 7.75L into the system.
Question 1: Bentley manual says 10.5L if the engine block is drained, so is the manual wrong or is something wrong with my E60?
Continuing on with second question, well the engine is behaving as normal sitting on 93F when it is on normal temperate and the coolant seems to be doing its job. Here in Australia, it is winter season (South Sydney) with early morning temperatures shown as 12-13 (feels colder). When I start and drive the car for first 5-10 minutes, whenever I stop the vehicle I see vapor smoke from the front grill like what you will blow from your mouth in cold weather.
Question 2: I don't see any other car giving out vapours from the hood, its seems only on mine. Upon smelling, I dont' smell any oil or anything. Is there something else that could be wrong or does this has to do with only taking 7.75L coolant?
P.S. Coolant used was from Febi Bilstein, supposedly the OEM supplier to BMW which is re-badged by BMW.
