I have an 1992 525i, my car was overheating and i didn't know because the antifreeze and everything was fine, the steering locked up and i got the car to my house in one piece.
then realized the belt broke for the fan i guess? so I am just wondering did i permanently mess up my steering or anything else from it overheating? and what are some cheap sites to buy a new belt, any help would be greatly appreicated! thank you!:)

How bad was it overheating, like redlined for 20 miles or slightly higher then normal for a few miles? Good chacne if it was not long that it did not cause any serious damage. You can try rockauto.com for a belt or even FCPgroton.com

fill with straight water and take it round the block a few times and get the car warm. then turn it off and have a look in the water and see if it is still water or if there is now oil in there as well and let us knwo

Because the the belt broke .The fan stopped pulling air through the radiator and the water pump stopped circulating coolant. The engine over heated. You are probably ok if you did not drive more than 2 miles at high temp. make sure the fan clutch is still working good .Newspaper roll test the fan clucth..ebay has 12$ serp belt. Other parts places will be near 20$. Make sure you understand how to relive tension on the pulley and that you weave the belt according to Bentleys manual.I would add 1 bottle Red Line water wetter, super coolant as preventive maint.

yes thats the trouble with the BMW design, the coolant temp sensor is away from the block and doesnt reflect the temperature there were it matters in these situations

My first car was a 91' 525iA, I drove it while it was overheating one day, like for 45 minutes while it overheated/dropped back to normal/overheating... cylinder head had a crack in it after that. Don't laugh, I was 17 in Germany with a provisional driver's permit allowing me to only drive from home to school or work, not even driving to school or work, I had no clue you had to shut the engine off if it starts overheating lol.

hey guys i really appreciate the insight, but there has been a twist in the plot, I finally got around to looking at it again and the belt didn't break it just fell off because my water pumpwas loose. bearing (i think) are blown.
Do you guys think i have to replace the water pump? thanks!

first do a compression check to make sure your head gasket has not failed. then if ok replace water pump, timing belt, thermostat, and backflush the radiotor. you should be good to go. if only driven a short time while it was getting hot you probably are all right with head gasket. check oil to see if there is coolant in it and check coolant to see if there is oil in it. if no to both you might be lucky.

OP,

Do an oil change and look for metal shavings. I'm not sure why your coolant low light came on if the belt just snapped? Check for coolant leaks / pressurise cooling system. Check and replace your spark plugs and inspect them for damage.

This is a good time to inspect your water pump and pulleys for seizing (that might have caused your belt to freeze and snap). Also check your fan clutch.

I do not suggest buying belts on Ebay.

Don't throw money at parts, inspect them first before replacing them.
