88 BMW 735i What are signs the water pump is bad or about to go? Heres Why I Ask

I'm experiencing different things and it was mentioned could be the water pump.

1) While driving car seems to want to cut off and even when the pedal is to the floor it will not take off for a few seconds.

2) Started smelling a little antifreeze in the car

Thanks in advance for the great feedback!

Re tthe smell:

This model is notorious for leaking heater cores - if it is, your up for a nightmare repair or simply bypassing it and loosing the heater.

and the hesitation can be a binding airflow meter, assuming the engine has been maintained correctly.

poor running is also possible from unmetered air entering the engine, from say a bad oil cap seal, dipstick tube seal or cracked crankcase ventilation hoses or the main air distribution hose.

this is a good way to trash your engine if you keep it up ... repairs are better so it operates as designed ... you can burn rubber doughnuts with the car if you like and put two inches on your chenny. waste of perfectly good engine to do that IMO and all that rot. you fox up that engine .. toss the car ... engine is worth more.

Maybe. Look at the water pump. If you see any signs of anything even a little suspicious, replace it. If you have enough miles on it to worry, replace it anyway. This car doesn't have one of the really bad water pump issues that later 7-series models had, but it has water pump issues.

This could be damn near anything and it's something you need to address immediately. This could be anything from a damaged O2 sensor wire to a vacuum leak to an internal engine problem. You need to worry about this.

This is most likely a heater core leak, and yes, you will still smell antifreeze even if the heater isn't turned on. These cars are notorious for heater core leaks, and when you replace the core with a new one, sooner or later that one will leak too. And it's no fun to replace either because the whole console has to come apart.
