Hi Everyone,
I have this BMW 545i - year 11/2003 and to this present, I have no problem with the engine. But a friend of mine said that this model gives a lot of problem with over heating. Please clarify me whether it is a myth or a real fact. Thank you.

According to few research on other forums as well, the 5 series in general water pump go bad after certain miles. Most people experience such issue once they reach 80k+ miles which cause the over heat. So just keep that in mind...

Like any other car, parts start to wear and after 75k miles you just want to keep an eye on things. My water pump and expansion tank went between 80-90k miles. The expansion tank is known to leak from the seem underneath and hoses will get old and harden eventual. Normal wear I think.

My Ride: 545i
I also have a 545i and knock on wood, it's been running flawlessly. I also agree that while the engine is great, other parts will require replacing like the water pump, thermostats, etc.
Love my 545i!
Love my 545i!

I always check under my hood almost every morning before I use for the day. Well I keep that in mind about the year of the car and its wear & tear.

The 545i is a monster! Pure fun on wheels.
Not the greatest engine gasket and seal design but careful maintenance (frequent oil changes) and avoiding overheating can keep them quite happy for a long time.
RE Cooling System - Very easy if the cooling system fails and overheats to ruin gaskets (the aluminum parts of the engine over expand and break the gasket seals). Not to mention you could be in the wrong place (stuck in a traffic jam) when it overheats, preventing you from getting off the road and turning the engine off quickly, and do serious damage to the engine itself (warped heads, etc.). And weigh the cost of towing, inconvenience etc. Murphy's law says it will happen on the way to the airport while going on vacation.
Proactive maintenance after 85K miles is the key. You will have a cooling system failure. The only question is when. If you repair each part piecemeal as it breaks you will have many chances to overheat the engine.
Save up a fund and do the water pump, thermostat, hoses and coolant expansion tank and you will be able to sleep like a baby for at least another 60K miles.

I'll do cooling stuff at 80k.
