Would you change the Water Pump
Hi All- Going to take my 2006 3.0si 6spd mt Z4 in for some needed maintenance (fluids & inspection). It has 56000 on it and has given me zero problems in the 4 years I have had it (other than the top motor - but that is another issue). My question is - after reading many threads - I cant decide if I should proactively change the electric water pump & tstat or wait until i get put on the roadside. It isnt the 56K that worries me, it is the 14 years of age. It is a weekend car mostly and it only driven about 3k per year. Any other preventative items you would do on a 14 yr old Z4 with 56K? I do change the oil & filter myself each spring - so that has always been done, but other than a coolant flush & brake fluid 3 yrs ago and an air filter, I have had to do nothing. Thanks!

I wouldn't. It's not an infamous issue and I suspect electrical motors / pumps are more usage-driven wear items rather than age-driven. I also really dislike anything that involves draining coolant.

It has been mentioned the electric water pumps appear to last longer on the E85 and E86 models perhaps due to less cramped conditions and more airflow - so less heat. I have 156k miles on mine and I've been getting water pump codes now found in INPA. So my pump will be changed very soon. Unless yours is showing error codes I would keep using it.

Whatever is more convenient for you. In general, water pumps can last but some don't. If you have the time why not. If it's an everyday car I would probably replace it, but if it's a weekend car like you mentioned it can wait at least for me.

If you don't go far from home and the towing cost is not much, it's your second car etc it's easier to wait. |

It's going to come down to will it be convenient for him to change it now or later?I could understand if his water pump is pushing 80k, but at the rate of 3k a year of driving he has another 7-8 years before he needs to really worry about it. Tempotantrum, if you change your coolant religiously you should be fine for a while it will prolong the life of the bearings in your WP. However, if you have the extra time now why not? I'll leave it at that. Last edited by T-Bears; 08-31-2020 at 07:15 PM.. |

Back then money was tight and workshop fees were not an option. This was on the E85 that has better airflow in the engine bay. Drove the on the replacement pump for another five years or 130k before trading up cars. Funny enough, I had my E89 for three days and the water pump failed. Yep 32,000 miles and 4 years old. Extended warranty covered the towing pump and loaner. I don't normally believe in replacing good parts, I was simply advocating risk evaluation. |

I guess we'll find out soon enough if the OP will have the time or money to install or take it to the shop. Was your E89 Manual or auto? I looked online the new Z4 will only be offered in auto. Auto is nice but two of my cars are auto, a 6sp manual Z4 would be nice. |

My Z4 3.5IS has the DCT. I love the DCT, shifts fast, on demand and hard. Exhaust note during a shift is near perfect for me.
I let my wife drive my cars and she does not like standards. Compromises people make to stay married for nearly 30 years. |
