The clip will prevent removal, but you can leave it "down" for insertion. It'll act like a spring lock. The hoses have a similar action with their clips. On installation, the clip can be up or down. I prefer down so it clicks loudly when inserted all the way.

Same for the main rad hoses and CVV hoses.

Ahhh...makes perfect sense...since the end of whatever you're inserting is like a flared barb. One way in, no way out...brilliant!

I had the same exact ah-ha reaction when I first starting working on my car ten years ago and wondered what these ends are all about.

thanks everyone. I'm not confident that the puny clip will hold (I know it went all the way in but I didn't even want to tug on it to see if it would fall off in hands again). I'll get another clip and replace the ET and thermostat as was suggested.

Take a look at this picture again. The center round nozzle...should that be sporting an O Ring as well?

Is there a hole in the center of that center protrusion or not?
Could that not be a groove in which a locking clip fits rather than an O-ring channel?

yeah you're right, no o ring. no hole in the center since the transmission fluid and coolant doesn't mix.

No that is only for mounting. No Oring there.

very very high engine temperature

hi guys today i was driving my car... parked it at home to pick up a few things . when i came out to leave the car would not start ! i turned the key and the the only thing that appeared on the dash was the airbag light the engine did not even turn over. So i checked the battery and jumped started it ... weirdly enough it worked fine.

However this was a bit weird as i had driven it about 60 miles before switching it off.

Now there is a new problem .... when i turn the key to position two the engine temperature goes straight to the red line .... on a COLD ENGINE !! also the mpg meter goes straight to zero. When the car is running on a cold start the engine temperature gauge remains at 3pm (red line ) and also the mpg meter stays at zero whilst driving.

Any help would be appreciated, going to take it for a diagnostic tomorrow but a little scared to drive it even though i think it a faulty thermostat.

Prob not a faulty thermostat since the gauge reads hot on a cold start.
Also two gauges are working incorrectly. Could be a gauge cluster defect.
Try the OBC hidden functions cluster sweep to check it.

I am looking to get a 2003 330 with under 75k, perfect timing to do the cooling system as it is still on the stock system.

Does anyone recommend the ECS set, or is it recommended to go with the OEM kit they sell? Also I know it is probably a dumb question, but is the stage 2 kit (link below) a good way to go, or should i go all out with the stage 3? I do not plan on driving this car much, perhaps 2k miles per year.

Not sure if they are all oem parts tho. That is important. Especially pump and ET and two main hoses.

ECS has similar parts, but you are correct not all of them are OEM. I prefer the aluminum water pump pulley though.

So I should be OK with stage 2? Or should I go all out on this, even though this car will get light mileage

Plenty of examples of fails for poor quality components. And many fail sooner rather than wait for high mileage. Heck, even the oe fails at high mileage!
You can buy components separately. Don't have to buy a kit.
I'd use only oem parts known to us on this board, and I did buy separate Al underdrive pulleys for my own car. So that's how I feel.
Unless you're on a real budget, and really HAVE to just get by.
Have tow insurance?

I was unaware the non-OEM was such bad quality, as some members here have bought the ECS kit without issues.

I will definitely take the advice, and go for OEM parts. The question is should I be going stage 2 or stage 3? Car has 72k on stock cooling system, will not be driving more than 2k miles per year.

Put together your own OEM kit. It doesn't have to be "Genuine BMW" just made by the OEM. It'll come out cheaper than the ECS kit probably.

Thanks, should I be looking at ECS, or from another source?

One item I think definitely needs an upgrade is the water pump pulley, would you agree the aluminum pulley from ECS is the one to go with?

To Shop:

Use www.realoem.com to get part numbers.

Then take numbers and go to www.furiousmethod.com to create a list of part prices to see who gives the best deal at that moment.

Already said I like the Al pulley.

I have their pulley. It's a nicely made product and I'd recommend it.

There are many forum sponsors that all have competitive pricing. Mango's first line of the first post in this thread has several...

You can add FCPEuro to that list. If you call them apparently they will match pricing with anyone and they offer a warranty with all the parts they sell.
