View Full Version : plastic flange/ overheating

hi all, I'm extremely new to this site, so please excuse me if I'm starting a new thread here about an old subject...

okay- so, four months ago, I bought my '98 318ti. it had 78,500 miles on it when I got it, and since then I've put about 6,000 miles on it. the guy I bought the car from had just replaced the radiator and the thermostat right before he sold it to me.

so you can imagine my disappointment the other day when my car overheated while exiting the freeway. I immediately pulled over and had the car towed to my mechanic, ($60) who said it was a plastic coolant flange that had cracked, ($375 including labor) which made sense since there was coolant everywhere. he fixed that, then he also replaced the thermostat because is was fried, ($50 plus labor) but it is still overheating. he said he thinks there is a chance of some engine damage, so he is going to check that out. ($1700 estimate) :frown: :mad:

my questions are these: one, if the radiator and thermostat were already replaced, why the heck weren't these stupid plastic pieces replaced at that time, especially if they are as notorious for breaking as I've been reading about on here?!

and two, if these f'ing plastic pieces are so notorious for breaking, shouldn't they maybe be recalled or something?

First of all you are being ripped off. Second did you replace the water pump? That's one of the biggest reasons why e36 BMW's overheat.

I took the car to a reputable shop in my area that someone from this site referred me to. I really have no idea about what repairs cost, as this is my first ever BMW...

no, I've not had the water pump replaced. and to the best of my knowledge it wasn't replaced before I bought the car. this is all really frustrating since I've barely even driven it!

These plastic flanges are behind the engine inbewtween the firewall and the engine. This is not a simple fix since you have to take apart some of the engine to get at the pieces. I had mine replaced when mine crapped out about a year ago and that price sounds about right. BMW should've made these pieces metal instead of plastic maybee the would've held up better.

One member says you got ripped off,not sure if he was meaning the car or what you just had fixed. If he new any better he would realize you did not get ripped off on the price of these repairs. Maybee he/she will understand that once this happens to them.. He should look up the part and read up on what has to be done top get at this part...

The m42/m44 don't have water pump problems like the rest of the e36 family.

BMWs in general are known for the plastic coolant parts failing somewhere around 60-100k miles. Maybe even faster if you live in a warm climate. It is the nature of plastic and it is a service item.

You don't expect BMW to cover all of your radiator hoses and belts do you? Those wear out just the same. After 8 or so years plastic that is constantly getting hot and then cold, hot and then cold will get brittle.

As to why it was not replaced when the other work was done.. Not sure. People usually want the cheapest way to get in and out of the repair shop. Most people seem to wait for these parts to break before fixing them.

well, it looks like a case of bad timing for me.... I just spoke with the shop and asked them about the water pump, the fan being plugged in, the temp sensor, and burping the coolant, all of which is fine... he said he is almost %100 sure it's a warped or cracked cylinder. :frown: so I'm looking at about $2000 total, when all is said and done.

damn those plastic coolant tubes, I wish BMW had made them in metal!!

question: shouldn't there be a beep that goes off when the temp goes in the red? I think that would've been an extremely helpful feature in these kinds of cases, since it's nearly impossible to keep your eye on the temp gauge at all times, (especially in LA traffic!) the bummer of the situation is that I had JUST looked at the temp gauge about three/ four minutes before this whole thing happened and it was fine.... crazy that so much damage can happen in such a short period of time!

Ever since i over heated and blew my last engine, I constantly check my temperature and even more now that i have the DASC. i try t check every 5-10 minutes or when i think i smell something. A quick glance takes 2 seocnds. Two seconds can save you 700 dollars :tongue:

Like shes really going to do the work herself.

Anyway, rgirl, if you plan on buying a replacement engine (500-950 dollars), i can ask my dad to do the work for you for a much lesser price than M shop would do it for, to swap over engines.

Make sure you have the system bled. All the air is out.. You may not have a warped head/ blown head gasket.

The way to tell is see if there is oil in your cooling system. Or if your engine OIL is milky, brownish. If you have this they yes you have a head issue.

But a bad waterpump or air in the system will cause the car to overheat.

I just replaced the rear plastic section. It took me about 3 hours. But I also did plugs and some parts cleaning. I didnt bleed the system correctly and the car got hot within 2 miles.. I shut it down and let it cool off. then bled the system and now its fine.

Bleeding the system is very important.


HOW TO BLEED YOUR COOLING SYSTEM:
It really helps to have a friend lend a hand by sitting in the car revving the motor and keeping an eye on the temp gauge. Start off by removing the coolant reservoir cap and the plastic bleeder screw right next to it. Fill the coolant reservoir with a 50/50 mix of coolant and distilled water. Have your friend start the car, turn on the heater to full hot on the vent position and rev the motor to about 2500 RPM, if the temp gauge goes past the 12 o'clock position, shut the motor off, let it cool down and start over again. Watch the coolant reservoir, as the engine warms up the coolant level should drop, refill as the coolant is sucked out of the reservoir. Watch the bleeder screw hole also, when coolant with no air bubbles begins to overflow then you're almost done. It's a good idea to have some paper towels handy to mop up any overflow. Screw the bleeder screw back in (be careful to not break the plastic screw) and continue to rev the motor, you should see a continuous stream of coolant spraying in to the reservoir from the small hole at the top. Continue letting that spray in to the reservoir while your friend revs the motor for a couple of minutes to ensure any remaining air is gone. If the heater is blowing hot air when you're revving the motor AND when the engine is at idle then your cooling system is properly bled. If your vents are blowing cool air at idle then you still have air in the system, try revving the motor more and/or squeeze the radiator hoses to help dislodge any trapped air. Once your system is fully bled, top off the reservoir and replace the cap. Check the coolant level in a day or two and top off as needed. (Courtesy of Understeer.com)

well, I asked the M shop if they bled the system properly, and they assured me they did and that the problem was with the 2nd head, that water was leaking out of it? at any rate, I'm having it towed to the shop the guy who sold it to me uses, and his mechanic is going to have a look at it and do the work for much less. mechanic #2 told me that he might be able to tell whether or not this engine had any damage to it prior to me buying the car, in which case, the guy who I bought the car from would swap me out into a different car..... so complicated! but I'm hoping this is the case, as I really don't wanna spend a bunch more money on repairs! (and 1996Bmw318TI, THANK YOU so much for the dad offer, I will definitely keep that in mind and keep you posted after I hear back from the 2nd mechanic guy!)

thank you everybody for all of the info, it's much appreciated!

Well look at this way. Your engine might not be so healthy no more if it went to the red area. You might have some internal parts damaged or fried a little. Im not sure how many miles your engine has. If your going to spend more than 1,500 in trying to fix the problem (which the engine might already been hurt from the over heat) i would suggest to buy another engine that is healthy. You might fix it, then a few months later itll just blow. Im not saying this will happen for sure but can be possible if the engine is internally damaged. If your lucky like me, you can get one for 500 bucks. Ill ask my dad for you how much hell charge for swapping the engines. I can tell you for a fact itll be cheaper than what a shop would charge. My dad is so cheap its unbelievable sometimes. I sometimes tell him why dont you charge more than you? I can tell you this, he takes his time so if hes busy, he can do the swap in 2 weekends. He takes a long time but he loves to do his job right, and rather take his time and do it good, rather than rush and mess up.

Does anyone have pics on these plastic pieces that go bad? I diffidently don't want this to happen to me(blown engine do to over heating). I heard the thermostat housing is plastic?

Where behind the engine are these plastic pieces or better yet do you have the part numbers or pics? I got 140,000 on my "95TI and never had this issue occur yet. Are we all doomed to have this occur to us?

Forget it...I found it on another thread.....Thanks all

I'll go for removing the intake manifold to get this job done. One, I need all intake gaskets and all heater hoses under intake. It looks like there are three hoses. While I got this intake off; does anyone know if there is anything else I should clean or replace besides those plastic cooling pieces. I might get three bottles of throttle body cleaner and brush to scrub intake. I wonder if there is anything I should do to maybe even the fuel injection system?
Note, this is all preventive maintenance. I don't want to blow my engine or have vacuum leaks or broken cooling hoses. Oh well, this could take all weekend. I hope I'll have a better idle, engine seems to miss at idle slightly.

All the new BMW come with plastic pieces as well. But I think the rule of thumb is 10years or 100,000 miles before the plastic breaks down from the constant heat. These car company's don't want your car to last for ever I guess.

Just so you know, it isn't always best to shut the car off right away if it starts getting hot. The best thing to do is to pull over safely, let the car idle, and turn the heat to full and the blower on full blast. Make sure all other engine loads, like AC, headlights, radio, etc are turned off. The heater core will act like a second radiator and should reduce engine temperatures significantly.

Once the engine has cooled to a normal range, shut it off (if you know it was temporary problem you could continue driving at this point). If this procedure doesn't work to reduce the temperature, shut the engine off.

bummer, I definitely feel your pain.... hopefully your engine is okay, because that's the expensive part! my gripe from the beginning is that there should really be some sort of warning light or beeping sound that goes off when the temp starts going into the red, as it's very difficult to keep your eye on the temp at all times- especially in traffic, etc... I was probably driving for less than 5 minutes, and my engine was screwed.

anyways, good luck!
