Have there been any problems with their parts before? I know they have a 1 year manufacturing defect warranty.

It's not missing much, but it's best to build a kit for yourself (it's cheaper). Using RealOEM, decide what you want to replace. I would try to get as many OEM parts as you can (not necessarily "genuine BMW").

Water Pump - Saleri
Hoses - CRP Contitech
Expansion Tank - CoolXpert (that's what Mango says)
Thermostat - Wahler
Radiator - Behr (I think, but Behr is good regardless)

I'm not sure on the sensors.

330ci should I renew my coolant system???

Hi
I've got an 04 plate 330ci it's only covered 13000 miles from new curious to know people opinions if I should renew the water pump and expansion tank due to its age and not the mileage.

Also is there anywhere in the uk any one knows of getting a complete kit to do so? I would want oem parts for the car if possible

Cheers for the help in advance

Has the coolant ever been replaced? I'd just do that. 13,000 miles means none of these parts have seen many heat cycles. Your water pump is definitely fine. Maybe replace the expansion tank if old plastic (but it's really a composite) scares you.

It got moved b/c it's a general cooling question. People will still see it. I'm one of the only people up right now though b/c I'm at work and I have nothing to do on Saturday. I just have to be here in case.

Just do a complete coolant drain and refill if you are in doubt. I would also change your oil. That needs to be done at least once per year even if you don't come close to the 15,000 mile interval.

Your car has such low miles that I wouldn't really be worried about much at all. The suspension bushings are probably still good and everything. I might do a brake fluid flush since that fluid is probably quite old. Brake fluid tends to absorb water over time. I'd also think about getting a new battery if that one is original.

I think many of the things you might be concerned about can be gauged by examination. Just as if a mechanic were going over the car to evaluate it. There are youtube tests for a number of things too.

Has anyone vacuum filled their cooling system? Any problems issues with doing that?

How do you do that?
What's the point?
Normal gravity fill does pretty well.
Fill, bleed, drive!

Why does this sticky tell people to replace certain parts blindly or based on mileage instead of doing a proper diagnosis? Like belts, bearings, and thermostats for example? It's a pretty wasteful use of money and time prematurely replacing those parts...

I called a independent BMW mechanic, 2 of them in fact. Both said that when 1 component fails in the cooling system, the rest are soon to follow.

Replacing the rest was cheaper than a tow, simple as that.

You asked a mechanic running a business if you should get more work done on your car. Why shouldn't he try to convince you to come in for more work in a situation of uncertainty?

And you pay $500+ for a tow?

I would not do it. The ET is designed for positive pressure and so is the rest of the system. I'm sure a slight vacuum wouldn't hurt it, but why risk it. The regular bleeding method works perfectly.

Not all tows are equal. What if you're 500 miles away from home on a road trip? or hell, even 100 miles.

Good you got it done, dreamliner. It's a vehicle--a mode of transportation. Not a pair of roller skates. Man up and pay $500 to keep it running.
