My Ride: 2001 330Xi
Im about to get a 2001 330xi that is in excellent condition, however it just hit 90K. So obviously this cooling system is the biggest priority in my mind. Would the best way to make sure I get everything I need be by purchasing the Level 3 kit from ECS? I just want an easy purchase where I wont get into the repair and realize im missing something...

http://www.ecstuning.com/BMW-E46-330...ine/ES2228847/

would you guy advise against buying the aftermarket kit? I like OEM, but $500 more...obviously you get what you pay for, so just wondering your experiences.

You might want to check the service history on the vehicle to see what has already been replaced.

It's my grandpa's. He's 81 and called me a few weeks ago asking if I want to buy his car because "his sport car days are over". The alternator and voltage reg were just replaced a month or so ago, but nothing has been done to the cooling system. I've already got my excel sheet going for all the stuff to full proof once I buy it from him. I've looked around for the cooling kits and the Ecs kit looks to be the best deal and it comes with much more than say the tischer kit...the tischer kit would be nice though since I could just go pick up the parts since I live in MD.

The kits on ECS Tuning are great and even the kit with the aftermarket parts is pretty good. I prefer going with OEM so I have no doubt in my mind that the parts will not fail in a few months and for the peace of mind but that's totally up to you.

Selamat Datang, NameIce.

If you are losing a lot of coolant each time you drive and it is not leaking, there is only one place it is going, out the exhaust. Most likely you have a blown head gasket. Did your engine overheat? Check the tailpipe for coolant smell. Check oil for coolant contamination, and check coolant for oil contamination. Also, if your coolant becomes pressurized after only 30 seconds to one minute of running, it is pressure from a bad head gasket. Check these things and report back.

Why the challenge? Mango freely shares his knowledge and experience in his own unique manner. This is an information sharing part of the forum for fanatics, to help us keep our cars running as designed.
If there is something he posts that you disagree with, just say so and say why. Please do not start a peeing contest here. Go to the Political talk part of this forum for that.

Cheers

Hi All,

Sorry for this semi annoying post as I should know the answer to this after having read this thread...I'm currently at 115xxx kms (canada).

I called a local well known authorized bmw shop today to do this overhaul and the technician said he didn't at all feel "right" doing an overhaul on a car that has not exhibited any issues (no leaks or overheating). His suggestion is basically to wait for something to actually cause an issue and deal with it then. He of course recommended shutting the car off, etc at any indication that things were going ary. The cost is also quite steep ($1200 Canadian dollars with the parts and labor).

I've read through a substantial portion of this thread and basically understand that I'm essentially around the km point where I should be doing this. Does everyone agree? Or are there owners out there who believe this should be addressed when something does truly break (doesn't sound safe given some of the stories on here but not sure if the failures are always so dramatic and truly non-preventable once an issue comes up). ie are ppl facing major failures because leaks were ignored, higher temps were ignored etc.

Ideally I would just be able to do this on my own, and thus the cost would be significantly lower and the decision would be easier, but don't want to screw anything up. What's the best DIY out there for this? Just want to feel more comfortable before tackling it...

Thanks so much.

Look up the individual DIY's for each of the cooling system parts. It's about a 6 on a scale of 10 to do the whole job.
Look on this forum and youtube.
You have to make up your own mind as to whether or not to PM all of this.

I would highly recommend either doing this yourself, or having it done, especially given the high miles. If your tech "doesn't feel right" doing a cooling system overhaul on a high mileage E46, he has no business working on your car. Find a highly experienced BMW mechanic that knows these cars well. Replacing all the parts at once is so much faster and easier and should cost a lot less than changing them in groups (belts/pulleys, hoses, rad/fan/tank/sensors). My engine got destroyed because of a coolant expansion tank failure that was both quick and final. Don't take any chances, listen to the great Mango.

It didn't take anything as drastic as this story to convince me. Long ago I just replaced everything in the cooling system, including the radiator.
What is amazing to me is that anyone can hear this testimony and want to ride out an old system until it fails.

For auto tranny, do I need any o-rings for the tranny cooler lines? What about o-rings for the heater hose?

You do already know you'll need to replace the tranny fluid thermostat?

You won't need to disconnect the tranny cooler lines. The little trans cooler easily disconnects on the coolant side.
