Plastic cooling system woes?
Some BMW models are notorious for failures of plastic parts in the cooling system. And I have experienced similar problems with Volvos I have owned. Our cars seem to be better than some.... but not perfect.
On one hand nobody wants to spend a ton of money when not needed. On the other hand I'd far rather spend $500 or even $1000 in parts and a pleasant day working in the shop, than risk being stranded on the side of the road in a cloud of steam.
So what parts should be replaced at what mileage or age?
My specifics: 2010 128i, 163k miles on it. Powertrain is stock. Daily driver, spirited use. I'm the third owner and I have service records. Nothing has been replaced in the cooling system AFAIK. This car has been super reliable and fun, best car I've ever owned. I would be happy to put some money and time into preventative maintenance, I just want to be smart and do the most critical items first.
What do you recommend?
