Temp seems to go up to 98c (seen it at 99c for a sec) then goes down is this normal ?
Please learn how not to double post. And erase one of the dupes so we won't be seeing double for years.

Chirping is very likely a drive belt bearing on the way to fail. Learn how to tell which one is bad or replace all three before you reach catastrophe soon. I'm not kidding.
Opening the bleed screw when warm and running will not only do no good, it will do harm. It will lose the good bleed you may have had.
Learn the in's and out's of your car better as these are beginner questions. Your car will stay in better shape that way.

Fluctuating temp may be due to old thermostat, or less than a perfect bleed. You must follow the procedure accurately.

Pull the belt and spin the tensioner and idler pulleys, they should be silent. Or use a wooden dowel and touch something solid as close to each pulley as possible. On the idler you could use the bolt that holds it on and hold the other end to your ear, the sound will transmit through the dowel. Just be careful of the belts.

Hi all,

after doing a cooling system re-fresh another weak point has come to light...

i have the ol' misty windscreen so it looks like im in for some heater core fun. Does anyone know if there is a way to tell what type of heater core i would have prior to pulling the stereo etc. out?

this:

Sorry for the silly question, but how can I find out whether my expansion tank has been replaced? As I've bought the car with no service history ( I know, could be tragic ) to me it looks newer, but then again I'm new to the e46 and I'm still trying to figure what needs to be done.

If in doubt, replace it.

It's recommended that you do a full cooling system refresh. Don't wait for even one item in your cooling system to fail - as it could be the end of your engine. I bought mine in Dec 2016 with 99k miles, a few records, and runs like a top. But I will be replacing the entire system per Mango's recommendation, as soon as the weather gets a bit warmer. I have all the parts already in the garage. If any of the parts I replace look to be in really good shape, might be able to sell them on ebay.

Yes I think it's probably the safest option to just replace everything to save any future hassle.

So from reading a bit of information I should not purchase anything except OE parts? There are cheaper parts on ebay but even being a young women with little knowledge I have some scepticism as to whether they will do my car any justice or just break within a couple of months and cost me more money!

Sorry if I seem like I have no idea, there is just soooo much information on here I'm having a hard time trying to figure out what's right or wrong! I have a 2000 318i in titanium silver, it's my baby and the very last thing I want to do is ruin it!

For critical parts like coolant hoses or expansion tanks most folks would advise OE. If there is a large number of users reporting good results with non-OE parts, then you can probably justify going that route. Certainly for something like an A/C compressor few owners would go with genuine BMW. You have to do some searching to find a consensus depending on the part. In general, most advise steering clear of Chinese parts which can bd confusing since some "OEM" parts could in reality be made there. Gotta do your homework.

I found that many more experienced E46ers are using FCP Euro to order most critical parts - they may not always be cheapest, but have a Lifetime Warranty on everything. I have found them easy to order online and shipping is usually free (over $49 in purchases). Shop ebay at your own risk! But saving a few bucks isn't worth it to me. (at least on mechanical items)

They also price match. https://www.fcpeuro.com/page/price-match

Thank you for the information! Much appreciated! Although I've had a look at the site that you provided and it seems they don't stock parts for the 318i model? Well I can't seem to find them anyway! :/

Double check your production date on the drivers side door sticker. The 318 seems to have only been made through 1998 in the US. After that the 323 in 99-00.

According to Edmonds.com

Hi all,

Against Mangos better advice, I thought I got away with re-using the ET base... it appears the plastic around the auto trans thermostat was too stressed and after 2 months worth of daily driving heat cycles in 40 degrees celsius (100f for the feet and inches crowd) unsurprisingly it split and started a slow leak.

I have a replacement ET base, and what I would like to know is; Will I have enough room after removing the airbox to replace this part without removing the fan and radiator from the car?

moral: listen to mango, especially if you live somewhere that gets proper hot

Thank you sir! "Listen to Mango" definitely sounds better than listen to the fruit. But these days--I'll take either!

As far as your install question, I'm not sure. It's been a while since I've been under the hood. These days, my ponytail just flaps in the wind. Sorry, I hope you figure it out, though.

Good luck!
