I am new. I've owned this 2000 stype for 10 years and it was a VERY SPECIAL GIFT to me from my husband who passed away shortly after. It has such value to me.

That being said, on a few trips into work in the morning since the weather change, I noticed the fan running after I had turned off the engine. No lights inside coming on temp looked ok.

I work at a large crane company and asked one of the mechanics to look and see what he thought. He found the upper hose leaking antifreeze. I found the hose was a 4 outlet one and had to order it. In the meantime, he took the old hose off put epoxy on it and put it back on. Put antifreeze in and now the car is overheating and pegging out the guage. The warning light comes on inside the car say engine power decreased.

They believe it to be air in it. Cannot seem to get it to stop overheating. Now he tells me I could have a cracked head. I am SO UPSET. Anyone with any advice PLEASE?!?!

 

Hi- I'll ask the mods to move your post to the S-type section to get maximum attention. In the interim, do NOT start the engine!

There are 2 bleed screws for your vehicle.
1- on top of the coolant reservoir. That's where you normally add coolant. BE VERY CAREFUL with that bleed screw, they are prone to be very brittle. This screw does NOT unscrew all the way, just a 1/4 turn or so.


2- Back at the firewall near the brake booster. The big black thingy on the right. Again be careful with that screw as well.


You are going to want to replace most of your cooling lines if you haven't figured that out already.


Good luck and let us know if the bleeders do the trick.

 

Another vote to change every hose on the car. The car is over 14 years old and they are a wear item.

Has any maintenance been done? Like changing the anti-freeze and transmission fluid?

Very important if you plan to keep the car.

We also don't have your car details which makes it tough to give answers.

You probably have a big air pocket in the engine from removing that hose, reinstalling and not bleeding the cooling system. As a result, yes, you've overheated the engine.


Pull and redo both heads. While you're in there, replace all of the timing chain parts, water pump, etc. You'll probably spend over $5k so be prepared.

 

I presume he means the car.

There's several tests that can be performed to confirm this. If so, then as tony has stated above, quite a few dollars will need to be invested to make it right.

Could you tell us how your mechanic determined that a head is cracked?

 

I would suggest this- first try to adress and seal any external leaks. If you have some leaking hoses- fix them. Also look for cracks around the coolant reservoir. When all the external leaks are fixed, bleed the system out of any air and drive around a bit. If it continues to lose coolant or if your coolant is mixed with oil and its color is brownish then start thinking about a cracked head. The head fix can be quite costly, so I would suggest to start with the simple stuff and then go on to the more complex repairs.

 

Guess she wasn't as desperate as we were lead to believe.

 

I feel bad that it was a gift from her departed husband that finally gave her trouble. I can understand the emotional value, as well.


It is regrettable that she didn't perform routine maintenance that would have likely prevented the problem. I'm servicing my own 2001 S Type 3.0 right now and replacing hoses, including the upper and lower that have the plastic connection. Those are known to become brittle and they go bad on BMWs too.
